You can wipe that partition without loosing your photo . Not wipe "internal storage" !!

Your contacts will be back logging into your Google account...

Other questions : Is it possible to set preferred network and timeout backlight hardware keys illumination ?
[LeEco Le 2 ROMs, Kernels, Recoveries, & Other Deve] laikexpert:
Your photos and other personal data are on "internal storage"

For all your existing Contacts is best solution, first to migrate/save on Google Contacts.

After that, when you logging into your Google account your contacts will be back on your phone.

CUOCO92 ROM includes polish language

and default browser is Chrome Web Browser.

- antutu score is same as stock if you have cpu on performance- 4k less if on adaptive which is fine. (i have cpu perfservice on i think)

-under cuoco display manager "dpi setting"- is is this even a viable option to change ? as far as i know the phone comes with 401dpi, this setting lets you take it up to 680? shauld it be done or not?

-Under advanced cuoco setings: quickboot is it viable to have it on?

otherwise the best rom, come with everything you need included, and if the bettery life is even a bit better its a no brainer to get the rom :)

First day it worked fine, 2nd day (after night, when phone went to hibernate) i started getting 'no sim card' again. Any ideas how to fix it?
