[Q&A] Xiaomi Redmi Note 4G LTE (dior) faulty proximity sensor - Redmi Note Q&A, Help & Troubleshooting

*problem*
If I make or receive a call on my Redmi Note 4G the screen goes blank and stays blank until the call is ended.
Whether the phone is near my ear or not.
I couldn't even click end call.
*solution*
1. Press to make a call and type the following numbers to get to the hidden menu.
2. *#*#64663#*#*
3. Go to number 7 (proximity sensor)
4. Follow instructions and calibrate the sensor
I've attached screenshots to give you and idea of what to expect.

Thank you for this information. I don't have the problem but it's interesting to know about the menu. For the record, it's also possible to get there through Settings, Additional settings, About phone, and four taps on the Kernel version (works for me on MIUI6 China Developer 5.1.23 version).

After calibration, how do you test the MENU button? It takes me back to the home screen.
The rest of the buttons - Volume UP & DOWN and BACK test fine.

Try long tap menu button, by default normal tap is task switcher, long tap is menu function. You can change it in settings.

After dialing a number, my backlight will just go out. In order to end the call or anything, I need to hit the power button to enable the backlight again. What could this be?

Settings, look at the settings.
I have, but it actually looks like HHC was the culprit. Uninstalled it and it works fine now.

Automatic key lock

Hello, everybody
When I press and hold down the "hang up" key, my phone goes in lock mode. That's great. But is there someway to get the phone to do this automaticly? For example after 30 sec or so. I've not found any solutions here in this forum.
I know there is some 3rd part program that can fix this, but I have read that there is some issues with these programs, so I really hope that I can manage to do this without any 3rd part programs.
I will be very happy if someone could help me with this issue
(I'm terribly sorry for my bad english)
Go to Start > Settings > tab Advanced.
There, just set the options you want. Basicly, when it turns off the display at the times you set, the phone also locks.
(actually, it only locks when the 2nd option is activated, which is something like "Turn off device when not used for...". It's not really turned Off, the Display just goes off, and the phone gets locked).

Thanks for quick answer.
Actually there is no tab Advanced when I go to Settings. I have three tabs in Settings, it's in norwegian, but I can try to transelate it to english: Personal - System - Connections. I can't find any of the options you mentioned in your post.
I also like to be more precise with my problem: My display turnes of after some sec, but that not the same as the key lock-function I want. When I press and hold my "hang up"- key I have to press "Unlock" in the down right corner and then I have to confirm it in the middle of the screen afterwards to unlock it. I want my phone to automatically lock after some time not only turn of the screen.
When I have my phone in the pocket I often accidentaly turn on the screen with the power button and the phone starts to call someone. That won't happen with the key lock activated.
Hmm, well, for me, when the Screen turns Off, it Auto-locks the phone. So what you want. This is with the Default HTC Rom.
I wrote the location wrong, it is:
Start > Settings > tab System > Energy > tab Advanced.
Edit 2: Ok, now I realised why this is working for me. I used HD Tweak to change something.
With what I did, I have *exactly* what you want: Device goes off after x seconds, and then locks.
1) I used HD Tweak (from this forum)
2) There go to: 4) Lock > 4.1 AutoLock
3) Turn that on.
4) Go back to this: Start > Settings > tab System > Energy > tab Advanced.
5) There turn OFF the 1st Option (which dims it to half screen brightness, but it's buggy with the option I mentioned at 2), HD Tweak Warns for it. So by turning off this option, you work around that bug)
6) Turn on the 2nd Option (Turn off Device after X time) (which actually means turn off Screen...)
Now, what this does in my case is:
1) After 1 Minute my Screen goess Off because of the setting under Start > Settings > tab System > Energy > tab Advanced.
2) Because of the HD Tweak, it locks the keypad.
So thats what you want.
Thank you very much, Seven_PRX! Your instructions worked perfectly, and just the way I wanted

With this solution, I had problem when the screen dims : the screen locks itself too. So, I needed to unlock it, but the screen doesn't light up no more. I had to switch my phone ON then OFF to have the full brightness back. But maybe it was a bug with my install...
But now, I use VJDeviceLock with its "VJDeviceLockInstall" that lock the phone when I switch it ON. If you have the problem I had, it might be the solution

That's why I don't have this problem you mentioned
Yep, I saw that just after posting my comment
But I like to have the light to dim to warn me that the screen is going off... So I thought I could give you another way to have an "autolock" function
Btw, a quick way to unlock your phone & turn the screen on is simply by taking out your stylus (this unlocks the phone & turns the display on). It's quicker than pressing the On button and then Pressing "unlock" twice.

Light off during a call?

Hi there,
I am a little ticked off with the way the phone switches the light off and you HAVE to press a button to get it back up when in the middle of a call.
Is there any way to keep the phone awake while on a call? Ofcourse, I HAVE tried out "Shake Awake", but thats a little buggy too.
And also, the buttons for Hold, Mute, Speaker mode and all those options come up only when you press the menu button. Is there any alternate dialler available or something which can get all these options on the screen while on the call like the iPhone as its easier to use it than press the button to get the options?
just install keepscreen.
edit: this will keep the screen alive. about the alternative dialer i don't know. but be aware that the phone has no proximity sensor, so you are prone to accidentally press random buttons.
Cool. Will check it out man. Thanks.
I have a different problem - since, sadly, Hero has not got a proximity sensor, I constantly drop my calls by accidently touching the end call button with my cheek. I believe that's a reason the screen backlight goes off so quickly during a call - when the screen is off, it does not react to touch too, so that accident call drops would be less likely.
There are still some serious problems though. First of all, screen timeout during a call is not short nough - while you can know that you must wait a few seconds before you can actually touch the phone with the face, others can't, so call drops are, sadly, unavoidable in such cases. The fact that hold, mute and other buttons are hidden under the menu button is a good thing not only because it keeps Android phillosophy straight, but reduces chances of unwanted misc. actions. The solution of this problem could be an option to disable the end call button, since there are dedicated hardware keys for that.
I have also noticed that if you minimize the dialer during a call with home button, the screen timeout will not be quick, so before continuing a call it's a good idea to bring the dialer back by tapping the hardware call button so the screen timeout becomes quiick again.
Very true. I thought about all these before I posted, but on the other end, I just said 'f it' to myself and asked it here.. hehe.
I wonder if iPhone users have such issues.
As someone in this forum mentioned, it is best to have the screen switched OFF during a call, unless you have something to do. This way, it prevents you from fiddling with the controls.
Not just the hero, earlier models too have this feature. It quite odd in the beginning, but you will love it later.

Not necessary!
During a call
- Press "Call" to hold (will also mute)
- Press and hold "Call" to activate speaker mode.

[Q] When makeing a call

When I make a call or receive one while talking I notice different apps will open, usually beginning with the world clock??? It seems to be due to touching my face to the screen. Can anyone give me suggestions?? My service provider is Sprint, last phone was a G nexus never experienced this problem with that phone.
I noticed this too. I found out (personal experience) was that it has a ton to do with having a larger screen and not giving the screen time to turn off or pressing the home key so I wouldn't hit the dialer. My solution was a quick tap of the power key to turn off the screen and no more apps popping up.

Thanks', I'll give that a try, guess this must not be a big problem, wonder if it may be an issue with our phones, not all S 4??
There is a setting in my device/call to enable Turn off screen during calls. The only trick with that is trying to access the pull down menu while in a call. You just have to make sure you avoid the proximity sensor so it doesn't turn off the screen.

Sgs4 kitkat dialer fix//workaround

Recently I just found out how to fix my girl friends dialer, I had the hardest time finding any info that could help me solve the problem.
Everytime she would try to make a phone call and have to push any button on the dialpad her phone would either lock up and not allow her to push any buttons or the screen would turn off until the call had ended.
After research I realized was from this double tap feature that samsung used to stop you from hitting dialpad with your ear or in your pocket...
Anyway this is how I fixed it
1- first you need developer option.. By clicking your build number, in about phone 7 times, when u back out you will see the menu.. Half way down the page you will find ANIMATION DURATION SET THIS TO ---- .0. ----
2 change lockscreen setting to tapping lock button... Instead of swipe..
3 . making sure anything to do with gestures while in call are turned off.. In accessiblity . when window pops up about some voice whatever... Cancel it ... And in accessibility turn off power button ends call. Also if you have custom ROM with active display u will find more to do with this. U want to make sure pocket mode and anything to do with it has been turned off.
4. If your phone is rooted lastly I deleted- voice dialer
Doing this solved my girlfriends problems for the time being. In the past, just kept coming back so I pray
Please let me know if thus worked for or has helped you.
thanks...
