[Q] camera not working properly after root, pic attached topic

This is what the camera looks like. taking up less space than usual. also none of the camera buttons / options work, i can only take photos with volume keys. cant change to front camera or adjust any settings
(Camers isnt using whole screen, the entire thing takes up only the top right corner.

Lastly, the bottom left touch button to flick between open apps/ programs isnt working either, and keyboard occasionally freezes.
And idea how to fix?

I rooted and using XPOSED.

Bought Xiaomi Piston 2 from Geekbuying, not sure if they are original (pics attached) topic

Hello,

I bought Xiaomi Piston 2 from Geekbuying. Received them today and I'm not sure if they are original.
The inner part of the cone that connects the wire to the earphones has the letter L or R in embossed black (not orange/brown like mentioned in some forums).
The outer part of the cone has embossed "mi" logo.

They sound OK.

Are they original?

Thanks
