Hey guys,

since aproximately one week, the software navigation buttons (Back, Home, Recent) on my BV9000 Pro-F stopped working, which renders the phone quite unusable.
Is there any information on that?
I tryed a factory reset with wiping cache an data already but it didn't got any better.
After the factory reset i could occasionaly use the buttons for a short time, then they stopped working again.

---- Phone_Info ----
Model: BV9000 Pro-F
OS_Ver: 8.0.0
last security update: 5. February 2019 (this is weak guys!)
Kernel_ver: 4.4.83+ (release Mar. 21st 2019)
-------------------------

Any ideas ?
Please help.

By the way, there is an other bug in the contacts list.
When i try to watch the group list of contacts that i have made, the app is crashing when i scroll down until all the accounts should be listed.
Any info or help on that?

Best Greetings, Chris.
