Lumia 720 weird behavior on WP 8.1

Hello guys,

I own a Lumia 720 and it is running on these versions of software..
OS Version - 8.10.12393.890
Firmware revision number - 3058.500000.1425.0002

Presently running on the Lumia Cyan update!

The problems that I'm facing are,
1. Proximity Sensor doesn't work at times:
When I pick up a call, sometimes the proximity sensor doesn't work(To the record, 7 out of 10 times it doesn't work).. which makes the screen stay on.. And sometimes it does work. (Should I be worried?)

2. Touch screen
When I click on the power button, it shows the lock screen without the time and date. Only this time, touch doesn't work and I have to click on the power button again to make this work.

3. Gyroscope Sensor or Tilt Sensor
When the issue 1 occurs, I can't tilt the player in Temple run game.

I'm not running Developer Preview version and having gone through a lot of bug lists I'm really confused and I ask this humble question. I'm worried if this is a problem of hardware.

Kindly help through!

Thanks.

Some of these even I faced when I installed DP,and I too own a 720. I'd suggest to withdraw from DP if problem is beyond control. Sometimes back my lock-screen started to behave crazy but its gone now and I do not know how. Wait till someone with more expertise on this tells you. Till then keep searching for answer but my advice would be to drop from the DP and see what happens,obviously after a full backup. Post here whatever happens.
