Dropbox Uploads Consume Available Space

I notice that the Android Dropbox app, when uploading a file to the Dropbox server, first copies the source file to a cached file. Then it uploads the cached file to the Dropbox server. 

Why? I don’t know for certain. Maybe the app developers wanted to ensure that the source file isn’t altered during the upload process.

So what?

The cached file consumes precious storage space on your phone.

Regain lost storage space

To regain that space, delete the Dropbox cache. You can do this from within either the Dropbox app or Android’s settings (Applications, Application Manager, scroll down to Dropbox and press the Clear Cache button).

Speed Up Twitter On Android 

I’ve been using Twitter on my Android phone and noticed that over a period of days or weeks it slows to a crawl. A simple way to kick Twitter back into high gear is to exit Twitter and just delete all of its data, and then restart Twitter.

On my Android 5 phone, I go to Settings, Applications, Application Manager, and scroll down to Twitter, then press the Clear Data button. You’ll be asked to confirm. Click CLEAR – you do wish to clear all data.

Exit Settings and Restart Twitter. It should find your profile and download your tweets. Now it should be faster.

Try this at your own risk. It works for me, but your mileage may vary. 

ES File Explorer devolves into junkware

I’ve become fond of — maybe addicted to — ES File Explorer on my Android phones. It allows me to quickly manage folders, files, drive space, etc. I wrote a gushing article about it in early 2014. However, the latest version (v 4.5) is a mess. Apparently the company changed ownership last year, and we now see the new owners’ values. It’s an old story in computer software: the original developer carefully perfects his baby ’til he sells it, then the new (often clueless) owner tries to cash in and ruins the product.

I’ve stored earlier versions of ES File Explorer apk files that you may download and install:

  • Version 3.2.5.5 is a rock solid release of ES File Explorer from early 2015. It’s my favorite version. Its older user interface requires fewer keystrokes than the newer user interface.
  • If you’d like, you can try the newer version 4.05. It has a new user interface, but hasn’t yet devolved to the awful state of version 4.5.

To install either of these apks, you’ll need to go to your device’s Settings / Security screen and temporarily allow installation of applications from unknown sources.

New Samsung SM-G360T phone

My trusty Samsung SGH-T399 phone began to flake out last week. First it insisted that a number of apps needed to be reinstalled, then some apps lost their data. These sound like memory failures. Within a few days, the phone refused to re-start.

samsung galaxy core prime
Samsung SM-G360T

I replaced it with a low-cost Samsung SM-G360T, for $140 from the local T-mobile store. T-mobile calls it a GALAXY CORE Prime™. It’s small (4.5 inch screen), includes LTE, a quad core CPU, 8 GB of memory, 5 megapixel camera, replaceable battery, and a slot for a micro SD card up to 200GB. To keep costs low, Samsung seems to have deleted the magnetic sensor, the automatic screen illumination control, and lighted “back” buttons. I can live without these niceties.

The phone includes Android 5.1.1, which in most respects is an improvement over my old SGH-T399’s Android 4.

I notice on T-Mobile’s website that they’re now discounting this phone for $99. I recommend it, if your needs are similar to mine.  At that price, I may buy a second SM-G360T, as a backup phone.

T-mobile updated my SGH-T399 phone

(Originally published December 9, 2015) Last week,  without warning,  my Samsung SGH-T399 Galaxy Light phone from T-mobile began to download and update its system software to version T399UVUAOH2. Stagefright Detector now reports that my phone is no longer vulnerable to the Stagefright virus.

My phone’s About screen reports that its Android operating system remains at version 4.2.2 (Jelly Bean), but its kernel is now dated August 25, 2015 (Korean standard time).

t-mobile stagefright 480w

  • Tip: If your Android phone is vulnerable to the Stagefright virus, you can reduce (but not eliminate) its vulnerability by, within the Messaging app, turning off the Auto retrieve setting. The Stagefright virus arrives within an SMS (short message service) multimedia message, so if your phone is vulnerable, you do not want to download these messages.

Update, February 27, 2016: T-Mobile again updated my T-399 phone. It still reports Android version 4.2.2, but now reports baseband version T399UVUAPA1 and is dated January 4th, 2016, 20:32, Korean Standard Time. According to T-Mobile’s note that accompanied the update, it improves voice over LTE (VoLTE) and unspecified security features.

Farook’s iPhone

Are you confused by the FBI vs Apple dispute regarding Syed Farook’s iPhone? I am.

In an excellent article published today, Cnet neatly summarized the delicate position in which Apple finds itself, following the issuance of a court order that compels Apple to help authorities unlock the iPhone 5c that was used by Islamic terrorist and mass murderer Syed Farook.

The nugget that surprises me is that the FBI appears to be preparing a brute force attack on this iPhone’s 256-bit AES encryption. This is a daunting task. To brute-force attack encrypted data that’s encrypted with AES-256, you need to try each of 2256 or 116,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000 possibilities.  That’s more than the number of atoms in the universe.

If Farook chose a strong passphrase, it could require thousands of years for most computers to decrypt his data. It appears that the FBI has serious horsepower to throw at this task.

Restore phone orientation sensing

Last week, my Samsung Galaxy Light SGH-T399 phone with Android 4.2.2 stopped responding to orientation changes. When I rotated the phone from vertical (“portrait”) to horizontal (“landscape”), the display no longer rotated accordingly. In vain I clicked on the Screen rotation button.

sensor test screens markedupI feared that I’d physically broken the orientation sensor when I dropped the phone the previous day.  I loaded a rotation app, but found that it was a pain to use.  Eventually I discovered (thanks, Google) that by typing an odd sequence of keys, I could peek beneath the operating system and directly examine the data streams from the sensors. When I did this, the phone’s screen rotation function returned.

Here’s how:

  • Run the phone app, which displays the dial screen.
  • In sequence, press the *#0*# buttons on the dial screen.
  • A hardware test screen with 14 buttons should appear.
  • Tap the Sensor button
  • You’ll see the numeric outputs of the Accelerometer, Proximity, and Magnetic sensors
  • Press the IMAGE TEST and Graph buttons for the Accelerometer. The displays should respond to movement of the phone.
  • Cross your fingers
  • Restart phone

That did the trick for me. Your mileage may vary.

A big voice for little phones

I love my little Samsung SGH-T399 Galaxy Light phone. One disadvantage of its small size is that its tiny speaker produces a tiny sound.

Etekcity Roverbeats T30 wireless mobile speaker

The Etekcity Roverbeats T30 wireless mobile speaker solves that problem. It gives my diminutive phone a big sound, yet is small enough (about two cubic inches) so that when I’m at home I carry it with my phone from room to room.

It runs on battery power for hours, but you must provide a battery charger with a mini USB connector.

Its only problem is that occasionally it disconnects its Bluetooth connection. This suggests that it needs to be reset, but there is no reset switch. I’m not convinced that turning off its on/off switch actually resets its CPU. Nevertheless, leaving the T3 off for hours does seem to restore its willingness to remain connected.

With that one connection caveat, I recommend this neat little speaker . . . and it costs only about twenty dollars.

Listen to podcasts on your smartphone

I just realized that I’ve not described how I listen to podcasts, recorded audio, and live radio broadcasts on my phone.

Prehistory

Winamp website
Winamp for Windows Screenshot

My first streaming audio experience was in 2000 with the Windows-based MP3 player program called Winamp. Its Shoutcast network of streaming sites is built upon the traditional broadcast model: content on each channel is delivered in a continuous stream. A listener may not demand or replay any content. There are (or were) thousands of Shoutcast channels. I still occasionally listen to Shoutcast streams on my phone using Winamp for Android (which may no longer be available). I wrote an article or two about Winamp’s latter day rough sledding.

Content on demand

I began listening to both live and pre-recorded audio with an older version of TuneIn. Its creator sold TuneIn to a company that has ruined it with too many ads and unnecessary “features”. I’ve stored an early version for Android. This older version is much better than the new version that’s available in the Android Play Store. If you have an Android device, feel free to download and install my version.

RSS Podcast iconWhen Tunein began to degrade, I turned to Podcast Addict on my Android phone. It’s very flexible, and its many options can intimidate a first-time user. Have patience. Its power is worth climbing the learning curve. I now use Podcast Addict for most of my phone-based audio listening.

  • Tip: If one of these programs responds slowly, go to Android Settings, More, Application management. Select the sluggish program. Press the Force stop button. Press the Clear Cache button. Restart the program.

Apple iPhone or iPad?

I recommend all three of these programs for Android. If you have an Apple (IOS) device, you may find better alternatives. I see on alternativeto.net that Apple supplies its own podcast program.

Tune in, turn on, and drop out in.

Listen to articles on your Android phone

When you want to read an article but don’t have time to sit down and read every word, have your phone’s @Voice Aloud Reader text-to-voice app read the article aloud to you.

@Voice app iconFirst, display the article on your phone (probably in a web browser). Press the Share button or icon, and choose the @Voice Aloud Reader. Allow a few seconds for the @Voice Aloud Reader app to start, load the article’s text, and begin reading.

On my Android 4.2.2 phone, the female voice is remarkably clear. It tends toward a monotone, and occasionally messes up (especially abbreviations), but is quite listenable. Within the @Voice Aloud Reader app, you can pause, rewind, etc., the reader.

Just plug in your earbuds, start up the @Voice Aloud Reader, and go!

Cel-Fi LTE signal booster

T-mobile works fine for me, except in my house. I think that the nearest T-mobile cell site is about a half-mile away, but the signal path is filled with old growth (signal absorbent) trees. I can’t use my cell phone on the ground floor, and it’s usable in only a few spots on the second floor.

Neither T-mobile’s tech support people nor its store personnel have helped. I read that T-mobile is now providing “signal boosters” to customers with weak signals in their homes. Apparently AT&T and other carriers offer similar systems.

CelFi LTE booster from T-mobileOn Friday, I fetched a new T-mobile “Personal CellSpot 4G LTE Signal Booster” from the T-mobile store, after paying a $25 deposit.

My booster is the “Cel-Fi” model RS3 or DUO, manufactured by San Diego-based Nextivity. It consists of two small boxes — the window unit and the coverage unit — and their wall wart power supplies. The window unit receives T-mobile’s LTE or HSPA signal (presumably at 1700 MHz), demodulates it, and transports the data via a 5 GHz unlicensed UNI link to the coverage unit. I placed the window unit on the second floor and the coverage unit on the ground floor.

cel-fi system schematic in house

What is its theory of operation?

Apparently the system is essentially a repeater. I have no idea how completely it demodulates the tower’s signal before creating the in-house signal. Is the in-house signal that’s transmitted by the coverage unit on the same frequency as the tower’s signal that’s received by the window unit? I don’t know, but I doubt it. Nextivity merely states that the coverage unit “cleans up” (whatever that means) the signal. Neither unit has any user interface other than some front panel LEDs.

Does it work?

Placement of both units is critical. I needed about an hour to get the system working throughout my house. Without field strength measurement instruments, I relied upon the limited information that’s provided by the units’ front panel LEDs. It works.

I’ve found almost no technical information about this system except a bit in a thread on Howardforums and a press release regarding Nextivity’s use of 1/4 and 1/2 Watt output power amplifiers in this product. If you have technical information — especially antenna radiation patterns — on this product, please let us know.

What if it quits working?

Occasionally (maybe once a week) the received signal from the Coverage Unit drops to one bar and/or my phone reverts to a slow EDGE connection. I’ve found that resetting the Cel-Fi system restores signal strength and LTE speeds at my phone. Follow these steps, in sequence:

  1. Remove power to the Coverage Unit
  2. Remove power to the Window Unit
  3. Wait 30 seconds
  4. Restore power to the Window Unit
  5. Restore power to the Coverage Unit
  6. Wait a few minutes while the two units establish a good wireless link and the Coverage Unit adjusts its output level

You should eventually see a full 5 bars received signal strength at the phone.

Is radio and TV broadcasting doomed?

The FCC plans to meet with broadcasters with a view to recovering some radio frequency (RF) spectrum from them. Recovered spectrum would be auctioned to cellular wireless broadband Internet service providers.

From a spectral efficiency viewpoint, this could make sense. Today’s modulation methods conserve spectrum (compared to traditional AM and FM broadcast signals) and the cellular model allows many geographically separated users to independently share one frequency. The packet model leaves each channel available for others whenever data isn’t flowing. From a consumer’s point of view, it allows program content on demand, rather than only when the broadcaster airs the content.

I wonder how much longer the RF broadcast model will make sense?

Does car ownership have a future?

We’ve heard the mantra, “the Internet will change everything”, but did we think that it — together with smartphones — would threaten car ownership?

1914 Renault print advertisementVarious ride-sharing and car-sharing systems may be reducing the need for car ownership. Reuters recently published a detailed article titled Rise of the car-sharing apps poses threat to auto sector.

Another article titled Car Ownership Ditched as Flexible Travel Tech Upstarts like Uber and Blacklane Reshape the Industry recently appeared in England. It claims,

The car manufacturing industry recognises that this disruption is causing a trend away from car ownership and has invested in solutions that complement their automotive offerings.

Both articles report that the following ride-sharing and car-sharing service providers are expanding into global markets:
Cars stacked atop each other

  • Uber
  • Zipcar
  • Lyft
  • BlaBlaCar
  • Blacklane

The writers also mention investors who plan to create new ride-sharing and car-sharing services in major cities around the world. Maybe this is the end of growth for car manufacturing. Maybe it’s karma from the General Motors streetcar conspiracy of 1930 – 1960.

Restore TuneIn Android app

I’ve used TuneIn on my Android phones until recently. Its creator sold it years ago. For the past year or so, it’s been devolving, confirming the theory that adding programmers to a project only degrades it. (Read The Mythical Man-Month: Essays on Software Engineering.) Here’s my current TuneIn review on the Google Play store:

2013 version was okay. 12.9.2 version is broken.

TuneIn iconIt WAS very good. Now it’s broken. Bloated. Sluggish. Meaningless error messages.  Too many ads. Frequent crashes. Stupid social net UI. Lacks setting to choose continuous sequential play or stop playing at end of each episode. Its new continuous play behavior of episodes confuses ads with episodes so you hear ad + previous episode instead of your chosen episode. Frequent false complaints that it can’t find stream. The Search function is now broken and its results are unsorted.

I uninstalled TuneIn, downloaded version 9 dot something from uptodown.com, scanned it with Lookout, and installed it on my Android 4.2.2 phone. Whew! It works much better than recent versions.

I’ve made TuneIn version 9.3 available for download at this link. It’s 8 Megabytes in size. (The disastrous version 12.9.2 is 14 Megabytes.) Feel free to download and install it on your Android device. (You must first change an Android security setting to allow installing apps from unknown sources.)

Update I ended up installing TuneIn version 6.7. It’s “only” 3.9 Megabytes in size, feels responsive, and doesn’t display obnoxious ads or play pre-roll audio ads. I’ve made it available for download at this link.

Record bike ride info

I recently installed MapMyRide on my Android phone. I’m very happy with it. It uses GPS data to record speed, distance, and route of each bike ride. I use all of its default settings except Auto Pause; I turned it on so that it pauses each time that I stop the bike.

MapMyRide scheenshotI like hearing my split stats (time, distance, and speed) read to me at mile increments.

When you return home, tell MapMyRide that you’ve ended your ride. You can view your route on a map as well as your total distance, average speed, Calories burned, and average speed for each 1-mile segment. You may save your workout details for later viewing.

The free Android version does everything that I want. The paid version allows real-time tracking of your ride by a friend or family member and apparently it also integrates with a heart rate, bike speed, and cadence monitor. There are also Apple IOS and Blackberry versions available.

I know that we can mount dedicated bike computers that will provide much of the same ride information, but that requires careful mounting, sensor wire routing, and calibration. With this app, a rider just needs to run the app, press Start Workout, stick the phone in his pocket, and go.

Restore Android contacts

I drowned my three month old Samsung SGH-T399 Galaxy Light phone. It slipped into my bath water as I was using it in the tub. I quickly rescued it, yanked out its battery, SIM card, and SD card, and tucked it into a nice dry bed of uncooked white rice for the night. In the morning it started normally, but its display flickered and failed after warming up.

Import contacts.vcf screenshotI purchased a replacement SGH-T399 phone and installed my favorite apps on it. My Google Mail contacts were restored,  but the remaining contacts were not restored. By moving quickly,  I was able to go to the Contacts app on the old phone and export them to a contacts.vcf file. Then I used a USB cable to make the old phone a slave to a Windows 7 PC host. I copied the contacts.vcf file to the host PC’s store. (The contacts.vcf file is located in the phone’s /storage/emulated/0/ folder.)

Then I removed the old phone from the USB cable, and replaced it with the new phone. Next I copied the contacts.vcf file from the PC’s store to the /storage/emulated/0/ folder on the new phone,  ran its Contacts app, and imported contacts.vcf. Done!

My new phone now has the contacts from my old phone. Both phones run Android 4.2.2.

Liberate storage on Samsung SGH-T399 phone

I discovered a method of freeing storage space on my Samsung SGH-T399 Android phone. Podcasts had stopped streaming, probably because the phone had run out of free storage space for caching. How could I create free storage space? I learned that the hidden /mnt/sdcard/.face folder had grown to 2.65 gigabytes and contained 67,000 files(!). I gambled that the facial recognition files contained there were nonessential.

I deleted the /mnt/sdcard/.face folder, then created a new empty /mnt/sdcard/.face folder. Suddenly the phone had 2.65 GB of free storage. Yesssss!

I used a terrific Android app, ES File Explorer, to discover this bloated folder, delete it, and create a new empty one. Its SD Card Analyst tool displays folders sorted in descending order by size. The .face folder was at the top of the list.

Note that the folder named sdcard isn’t actually the physical sdcard. For some reason, Samsung’s Android file system calls this phone’s internal storage folder /mnt/sdcard. The physical sdcard is named /mnt/extSdCard.

OpenSignal app for Android

About a year ago, I wrote an article about my attempts to locate T-mobile’s nearby cell sites. I’m still having difficulty.image I’ve tried several Android apps that measure signal field strength, with varying success. I’ve had the best results with OpenSignal 2.0 (available free from the Android Play Store). This YouTube video is a good introduction to the app.

OpenSignal seems to do a good job of measuring signal strength and data transmission speed. However, its estimates of cell sites’ locations aren’t at all accurate. I think that it relies upon its own database of cell sites’ geographical coordinates — and these data are inaccurate. It’s frustrating, because everything else about OpenSignal works nicely.

Most of OpenSignal’s many features work well. It has the polished feel of a good commercial app. I gather that OpenSignal regularly updates their cell sites location database, so there’s hope. In the meantime, I give it four out of five stars.

Samsung Galaxy Light 4G LTE SGH-T399

My trusty Samsung SGH-T679 phone stopped accepting touch input last Friday. I replaced it with a Samsung Galaxy Light 4G LTE SGH-T399 for T-Mobile phone. Like the T-679, it’s small and lightweight, but it’s much more powerful. T-Mobile is discounting them for $99, unsubsidized. At this low price, I didn’t expect such a great phone.

Samsung SGH-T399The phone’s performance is amazing. Apparently it has a quad-core CPU with separate GPU, 1 gigabyte of RAM, and 8 gigabytes of storage. It includes a slot for an SD card. The phone is fast and smooth. Its operating system is Android 4.2.2, which includes many refinements. Its email client — in fact, everything — allows more tweaking than my old SGH-T679 did.

The radios include LTE (true 4G), 802.11n WiFi, Bluetooth 4.0, and NFC (near field communication). Ookla SpeedTest reported 14 Mbps download speed while connected via LTE with a signal strength of about -100 dBm. I’ve seen download speeds of 29 Mbps via LTE with stronger signals.

Here’s a 12 minute video review by a happy SGH-T399 owner. This phone delivers megatons of bang for the buck.

Addendum: Like my old SGH-T679, the SGH-T399 occasionally refuses to accept a battery charge. I’ve found that the same reset procedure works for the SGH-T399.

I nearly melted down my phone

While listening to a podcast on my Samsung mobile phone via the Tunein app, a pop-up announced, “Charging paused. Battery temperature too low or too high.” The pop-up remained on screen until I unplugged the charger. The battery had only about a 6% charge, so as soon as I unplugged the charger, another pop-up warned that the battery needed to be charged. Catch 22. Room temperature was probably about 77 degrees Fahrenheit.

imageI grabbed a cold pack from the freezer and rested the phone on its icy carcass. The over-temperature warnings ceased while I simultaneously listened to the podcast and charged the phone’s battery.

Decades ago, I helped develop military radio communication hardware. The products needed to pass environmental tests for vibration, shock, high and low ambient temperatures, and humidity — while under continuous full-load conditions. We invested many hours in heat management.

My mobile phone is clearly incapable of passing such tests. It’s intended for intermittent use — what’s known as low duty cycle usage. I’d guess that my phone can handle about a 10 to 15 percent duty cycle at full output.

This is probably as good as we can expect from consumer-grade products. We just need to have frigid cold packs ready if we want more.

Listen to podcasts when streaming fails

I listen to loads of pre-recorded and live podcasts on my Android phone. podcast icon headphonesMost are technical; others are about ideas, current events, science, and sports. Duration varies from a few minutes to a few hours. My go-to podcast listening app is Tunein. It works fine 9 times out of 10. Occasionally, though, I’m unable to stream the entire pre-recorded podcast file.

Usually the problem seems to reside with the podcast server, but sometimes the IP transport is at fault. Regardless, I then resort to plan B: I first download and save the mp3 file, then use the Winamp or VLC app to listen to the downloaded file. On my (2.3.4 Gingerbread) Android phone, both players are more flexible than Android’s built-in sound player. Winamp works well, but it may no longer be available.

A quick fix for Android net connect problems

Airplane Mode screenshotOccasionally my Samsung Insight II phone (SGH-T679 running Android Gingerbread 2.3.6) quits communicating via IP with Internet hosts. Often, a wireless connection to a T-Mobile tower exists but there’s just no IP communication. Also, occasionally my phone insists that it can only establish a (low speed, perhaps 50 kbps) EDGE wireless connection to the tower; it refuses to connect at higher speeds (such as UMTS, HSDPA, or LTE).

A simple fix — short of shutting down and restarting the phone or system troubleshooting — is to temporarily place the phone in Airplane Mode (which shuts down its wireless radio transceivers) and then turn off its Airplane Mode (which starts its wireless radio transceivers). Your phone should connect to the cell site with the strongest signal — which may be different than the site that it was connected to before. Nine times out of ten this works for me.

Disguise your smartphone’s phone number.

Burner screenshot on smartphoneWhile watching a Youtube video clip about the recovery of a stolen bicycle, I learned about Burner, a smartphone app that allows a smartphone user to temporarily mask his or her phone number with an alias phone number. It’s available for iPhones, but not yet for Android phones. (originally published on 31 December 2012. 9 July 2014: Burner is now available for Android phones, as well as IOS.)

Theft recovery seems like a perfect use for telephone anonymity. The victim, who’s a Portland, Oregon resident, responded to a Seattle Craigslist for sale ad for what seemed to be his stolen bike. He used Burner to make his phone calls appear to originate in Seattle.

Bike theft is a low-risk occupation. Watch a NYC resident steal bikes in public view.

Samsung SGH-T679 not charging

Occasionally, for no apparent reason, my Android phone refuses to accept a battery charge. (originally published 15 February 2014)

Samsung Exhibit II SGH-T679 phoneHere’s the only way I’ve found to fix this problem on my Samsung Insight II SGH-T679 with Android 2.3.6 Gingerbread phone:

  1. Remove charger
  2. Turn off phone
  3. Remove battery
  4. Remove SIM card
  5. Remove SD card
  6. Wait at least 3 minutes. (I’ve had to wait as long as 60 minutes.)
  7. Replace SD card
  8. Replace SIM card
  9. Replace battery
  10. Turn on phone
  11. Plug in charger

This reset procedure works for me. It may or may not work for you. (8 Oct 2014) It also works for my new SGH-T399 phone.


Update

7 August 2014Samsung charger This may or may not be a coincidence, but I’ve found that since abandoning third-party battery chargers and returning to a Samsung manufactured charger, my phone’s battery behaves better, without loss of charging function.

I’ve also stopped buying third-party batteries. They’ve been short-lived. I found what seems to be a genuine Samsung battery on Amazon. The combination of genuine Samsung battery and Samsung battery charger seems to provide both longer battery discharge times and better charging behavior.

I’ve not needed to resort to the charging system reset procedure since installing the genuine Samsung battery and using the genuine Samsung charger.
