Hello,

I've acquired a BV6000 in september through the site "GearBest". I was quite happy with it until today : without any notice, or specific manipulation from me, it seems the hole interface changed. But when I go to the settings, it tells me it still operates on the Android 6.0.

Here's what has changed :
- The home button doesn't work anymore
- When I use the power button to turn off and on the screen, the panel "slide up to unlock" doesn't appear anymore.
- When I press the "power" button, the options for setting the phone on "vibrating" or "no alarms" don't show anymore
- It appears no notification comes up anymore
- When I slide down the notification menu, the config panel (screen luminosity, turn on wi-fi, localisation, ringing/virating etc) doesn't appear anymore...

That's pretty annoying. Especially the config panel and "no use" of the home button...
What can I do ?

Best regards,
Gaël
