Please set ringtone volume to max (30).
After that, shut down the phone copletely, and after that boot the phone.
After the boot, is the ringtone volume still 30 or is it down to 13?
the phone language are english and indonesia ,you can choose language in keyboad and language +region,then the Apps using portuguese ,but in system places are still english,i think it not important,just few words.
My phone is Huawei W1-U00, and i installed the developer preview.
All good, except for the "empty temp files", that isn't working...When i select, it begins and stay in "busy mode", but if the display go locked, when i unlock it stops erasing, and the size keeps the same...
