The new lollipop version keeps crashing and freezing with various apps. I have tried rebooting, and even doing a factory reset to no avail. For example...the game words with friends immediately closes after it opens, as does the app Mimi (a 4Chan reader)...both if these worked flawlessly with the old version. Also, at random times when using the app Reddit, the phone will lock up and become unresponsive...again, this is since the update. The battery also drains faster than before, and the keyboard settings change by itself. I wish I could simply go back to the old android version. Any ideas about what the problem may be?
