Antwoord op "My sound quit working"It might sound overly simple, but if you haven’t done so already; power off and power on again. Still no sound - check the speaker for debris - and if you have a small firm brush you can clean it out or even better is blue putty. If neither of these is the fix, check for updates in the system settings. Hope this helps.
Antwoord op "My phone has spots on the screen but not dark spots. Help?"Sounds like what’s sometimes called image persistence. Ideally you would start by powering the device off for an extended period, 24-48 hours, but assuming its your only phone and not practical to do so, you might try changing your wall paper to a solid color (white or black perhaps)and slide over to a screen with maybe one icon on it, or open an app that displays a solid color for awhile, this may help.
