It is best to do a factory reset after every android update. This one is even more critical because it changes the main runtime. I'd suggest doing it inmediately.Is it best to do a factory reset after getting lolopop update?
App data is precisely what you want to reset with a factory reset, as it carries old config that might break the new one. There are aps like Titanium backup to save sms and stuff to your sd or pc!Won't I lose all my apps and data?
Can I backup everything by just copying everything to my PC?
Edit:
I really don't want to lose my app data or text messages so how would I back this up?
