Since Lollipop, Messages and K9 Mail are crazy slow, near unusable (probably other apps, but those are the ones I use most). I've restarted a couple times. Help!!!
Have you attempted to boot in safe mode and if so and failed or no success, have you considered backing up and resetting the device to factory?
I got unwillingly slapped with 5.0 last night, took 2.5 hours to DL and install on my M8. Texting all day has been excruciatingly slow and randomly timing out on server error 65535 (which basically means "I dunno LOL").
