After the lollipop update my phone's screen would turn on for no reason. I've done some research on the xda or android central forums (can't remember where/which forums). All I remember is someone said to download a app called "notification history" and watch for anything unusual. Well after a day I checked the log and I found that the notification that appears when the keyboard is open is what is causing the issue (see screenshot below). I already did a system cache wipe but to no avail and I really don't want to do a hard reset unless absolutely necessary.
