It seems you have a faulty proximity sensor, go through Diagnostics and see what's the result?

That's it! It vibrates even if I'm not blocking the sensor.
Any idea on how to fix this? Do I have to flash anything?

Nevermind I just found the problem. It was my screen protector that was causing this problem with my proximity sensor.

Restore stock FTF using flashtool and we user data, then re-diagonoses, if it still mal-function, it should be a hardware issue.

Ambient/Proximity sensor emitting dim red light 24/7

I have a strange problem. My phone's ambient/proximity sensor seems to be glowing dim red all the time. its really visible in the dark. it only starts to glow when the phone has booted into android. during the booting it stays off.
I understand some people will think I am confusing the LED for a sensor but let me assure you thats not the case. I am actuallt talking about the sensor situated on the right side of the earpiece beside the "SAMSUNG"'s letter G.
Its from Viber. Uninstal it.

Thank You, That seems to fix the problem. However whenever I use the messaging app the dim red light comes on again.
Furthermore, Is this dangerous ? as I would just ignore it and keep using viber if its not a big deal.
Thanks

Nothing dangerous, you will see the sensor light in messaging app because the very same is used for Smart call feature

[Q] My phone reads out emails loud when s-pen is near the screen!

My phone reads out emails loud when s-pen is near the screen! What should I do to turn this feature off?
the only time I've heard mine read anything outloud, other than caller id, which is an app I have setup, was when I inadvertently turned driving mode on-check for that in your toggles

Hmm. I read of people having trouble with hovering over the screen with the s-pen and it acting like it was already touching the screen. They said hitting it against something hard fixed the issue. Try that? Lol!

This is the only thread I can find about this, so I'll revive it here.
I have car mode off
All Accessibility features off (except for my Pebble notifications), in the Talkback Accessibility, I unchecked everything (just in case) even though it's off.
Under Text-to-speech output, if I choose the 'very slow' speech rate, I can confirm that the emails are IN FACT spoken more slowly.
How do I stop this text-to-speech from happening? I can't find a visual impair setting anywhere.
Edit: I FINALLY FIGURED IT OUT.
Even having Pebble on Accessibility notifications (for some reason) enables TTS features, no matter what you disable. This has been realized for other Accessibility options in Touchwiz before, so for anyone having this issue, here:

Hopefully it's fixed in future software updates!

Problem during calling it stays black screen

Anyone have the same problem during calling? The screen stays black after putting it in the face and after call end I still need to push the power button 2-3 times to turn the screen on back.
P.S.
I am using Official Kitkat version non-rooted.

Sounds like a bug. Re-flash or repair it in PCC or do a factory reset and see if that fixes it.

Ok I will try to repair through PC companion. I think I am the only one having this kind of problem because I have been searching the forums to look for solution. Until now I can't find anything having the same bug.

Yup, that's true. Are you using a screen protector on top of the anti-shatter film? If yes, the solution is probably calibration, which is very easy.
Sent from my Desire HD using Tapatalk
How can I calibrate the proximity sensor? I haven't done PC companion repair because my Internet connection was so slow. And yes iam also using generic screen protector which doesn't have a hole in proximity sensor. That's why I want to try fixing calibration proximity sensor first.

I can confirm that the cause of my problem was the screen protector. I removed it now and my phone is working fine now. Thanks to those who help me. :thumbup:

I cannot see the calibration feature either.
I have no screen protector, the cell is clean and quite new. I tried xperia disgnostic and it tell me the proximity sensor is always detecting something. I tried calibrating the sensor with *#*#7378423#*#* but the ability to calibrate is not present only the testing. According to sony pc companion i have the latest version. I just resetted my phone to make sure it was not the problem.
Build Number: 14.3.A.0.757
android 4.4.2
I suggest to revert back to JB 4.3 to do calibration. Then try again flash Kitkat and look if it works.

Re-calibrate the proximity sensor, dial *#*#7378423*#*#. I cant remember the menu it is in as I'm not on Sony firmware atm.

I'm sorry I'm not familiar with WhatsApp.
If you tried a different messaging app you may be able to determine if the problem is related to the app or the phone.
