Factory Reset your phone, add one app at a time back.
this is exactly what I did. Despite telling my htc one m8 to backup I lost all my contacts
I at least had the good sense to backup all photos on my computer.
So now I'm starting fresh and it immediately went and updated to lollipop. What are some must have apps?
I have nova launcher prime (no idea why I spent money on this but *shrugs*). Any other good launchers, etc. I hate pretty much stock anything, not good. My phone is really used for texting, web surfing and google hangouts with the occasional email read here and there. I wanna keep it fast. Been looking at a bunch of top 10/20/50 lists but I'd thought I'd ask what gaf uses.
Mostly just texting, phone app, launchers, calendar and of course delicious free icon packs.
EDIT: And a good cover app. I was using this really cool one (I think called just "cover") but it wasn't compatible with lolipop and had no music buttons.
