Lenovo Vibe p1m suddenly slow
Exactly this happened to me today, at morning I was watching videos, then I use the mobile again, and i cant even load youtube! Ill try deactivating some apps as phaethon said.

Deactivating some apps and uninstalling some helped, but mobile is still very slow :/

So I decided to factory reset my phone and everything is like normal, I have no clue what was the issue :/
