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.
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.
