Settings and apps not saved

[MarkHaysHarris777]

Sorry if this question has been answered already, I searched but couldn't find a thread of faq.

I have got everything running on the LCD 7 inch screen, pine64 working perfectly. Three things:

- settings or apps are not saved: each time I need to set my Play store account, wifi etc etc. Is there a fix for this?
- my screen is not filling the LCD screen entirely. What causes this?
- I have no sound, or is that normal with the LCD version?

Thanks for you ideas!

hi, you will need to solder the power switch in place, and solder the reset switch in place.

... do not just remove the power from the unit. After you make changes, and save them, remove power with a shutdown , from the power button;  not a click, but a long press and 'hold'.  That will bring up the power off dialogue/ your settings will then be persistent.

In display settings you can set the default resolution. Try that. 

There is no sound in the default Android image <sorry>. Also, there are no sensors, and the screen is locked into landscape mode only.
