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(s) and download your tweets. Now it should be faster.
Try this at your own risk. It works for me, but your mileage may vary.
