Phone just for entertainment
I have an mt6589 phone and recently it just stopped detecting the network, after trying everything I realized there's no hope so i decided to use it as a phone just for games and entertainment. It's rooted.
I turned off messaging, calendar, and i accidentally turned off "phone" service because I confused it with dialer.
I use games, and browser and calculator.
Any recommendations to boost gaming performance or other tips?
PS: i do not have a custom recovery installed because i fear i will brick my device, just granted root rights.
