Well since yesterday my phone starts to freeze frequently. I removed my latest added apps but it still freeze. Often the screen turns black but not always. Besides recent installed apps i also removed apps that stay resident in the left top corner of the screen. (my phone became a lot faster after that). And i removed a few games also. The problem is would like to start fresh but some data on it inside some apps i depend on for my work, so.. i cannt do that. Are there ways to trouble shoot android, and find the program that freezes it ?
