I have an HTC Inspire and am running MIUI 1.11.4. Occasionally, my lock screen will freeze up and i'll be unable to unlock my phone. The slider won't slide or anything. My battery percentage will still work as my percentage will change, but my phone will be stuck on the lock screen. The clock freezes also. The only thing that would be "unfrozen" is the battery percentage. This happens occasionally, i guess a few times a week. The only way to fix it, that i know of, is to take out my battery and put it back in. That itself is painstaking as I have a double layered case on my Inspire. Does anyone else have this issue? If so, any ideas on what's going on?
