[dadsterflip]

There's a few things id like to address if people who brought it doesn't mind answering.

1. How's the power buttons?

2. Speaker still low and can't hear much out of it?

3. Is the bezel made out if cheap plastic?

4. Any improvements on the vibration?

5. Call quality? Been improved?

6. Have they moved the notification light or made it brighter?

I had a tb and buying this for my wife but would like to know id the issues still exist.
Thank you for you time.
