hope this helps on most often case
What about if someone does not have titanium and still this happens?
This usually happens when you change roms, even official stock, and you do not wipe data.
Wipe data is done to stop this from happening and also enjoying the rom from its basics so that it does not use any previously saved data from any other rom.
That is one of the things too.
And com.processes.acore wont let you use your phone for long enough.
Everything around just keeps crashing.
Press Thanks if I helped
