Now i tried not to access any Bluetooth units, for 24 hours, BT turned on...and then I tried to pair a BT unit, first the Headset...ther pairing worked, how ever after 10 min. of music the phone drops the connection...then I tried to pair my MI band 1S, no joy, didn't work, tried to clear the memory...tried again...nothing, the phone couldn't see my MI band 1S.
Restarted the Phone...and now it was enabled to find the MI band 1S...and the headset...waited for 12 hours tried again...
MI Band can't connect...
My guess are "some kind of memory/buffer overload in the BT modul" I never ever seen a problem like this i any other phone...could be a build error in the hardware... I really hope this is getting solved...I on the edge of selling my phone...
This is so big a problem that I losing faith in the Xiaomi product...
I NEVER EVER owned a phone where you needed to "wipe Cache and wipe Dalvik" all the time...only if you were working with a DEV ROM...but I only use Stable Global ROM's...and I been using smartphones of the last 7 years....
