My keyboard now just stops working seemingly randomly. This has been happening since the afternoon of either Thursday 11/15 or Friday 11/16. It does not matter what keyboard app I'm using. I normally use Swiftkey, but this also happens with Swype and the standard keyboard. The keyboard pops up and the keys respond to the touches (i.e., key changes color and enlarged briefly, or whatever the relevant indicator is on whatever keyboard I'm using) but (a) no text appears in the input boxes, and (b) no word predictions pop up. Sometimes rebooting the phone fixes the problem, but sometimes it does not, and the problem has ultimately come back every time. The touchscreen otherwise works fine--it seems clear that this is purely a software issue. It doesn't matter what app I'm trying to type into--though I've noticed that sometimes I can bring the keyboard back to life by opening Facebook and trying to type in there. I assumed that meant that Facebook was the problem, but the Facebook app hadn't been updated for awhile when this started happening, and uninstalling Facebook didn't fix the problem. I downloaded the Addons Detector app for the purpose of identifying apps that were recently updated, thinking that doing so might help me identify other recent app updates that may have caused the problem. But even after rolling back or uninstalling anything that had been updated recently, the problem persists. The only other clue I have about this is that the keyboard issues have been coupled with severe battery drains. My battery used to drain about half way on a normal full day's use (15-18 hours or so). Since this issue started my batter drains fully before the workday is over (10 hours, max). Help!
