[Q] How to calibrate/ fix the proximity sensor of MTK 6589 [Konka V981 rebrand]

Hi, I've been having some problems with my proximity sensor lately.. I have only noticed it during my first call last January in which my girlfriend called me and upon finish I checked my screen to see that it's still black, tried to power on/ power off, but only the capacitive buttons would light not the screen.
I have used Phone tester to check my proximity sensor and tried it.. It says Waiting... then I put my finger on top of it, it says Near.. After I remove my finger, it's still stuck on Near.. So clearly , my proximity sensor is operational but is at fault or bugged.
Bottom line is, does anyone know how to calibrate or fix my issue? I have a Konka V981 phone, rebranded here in my country to what's now called Cosmos X2.. With an MTK 6589 chipset.
Thank you in advance to whoever could help me solve my problem. Hoping to find the solution from the professionals in this forum and/ or site.

try flashing a custom rom

Oh I forgot to mention that I've flashed multiple ROMs onto my unit but the problem still persists... I've tried about 6 roms and all of them have the same output, my proximity sensor is still at fault.. From Waiting... to Near... and never going back to Far.. It should be, or the normal should be near upon putting my finger or something in front of it, to far, removing the object, or my finger from it..
I tried a Note 3 rom, whereas I noticed that the proximity sensor wasnt needed for call sessions, whereas I could just power off power on when Im on call so my face wont randomly tap the screen and make a mess.. But I don't want to keep the Note 3 rom, so I flashed back to our modified Stockrom Android 4.2.2.. And then the problem came back..
If only someone could help me calibrate or at most turn it off.. Id be grateful.. But Id be more grateful if we could just calibrate it rather than turning it off

[Q] proximity sensor issue!

Hv Micromax canvas magnus a117
how can I disable the proximity sensor ?
Comment:
Hey guys I broke my phone's touchscreen glass (and the proximity sensor stopped working after that)
now when someone calls me the screen become's UnTochAble , so I can not for example dial a number or Hang Up when I am in a call .
I undrestsand it is because the phone's proximity sensor that thinks the phone is close to my ear and it shouldn't allow any button to be pressed. I cannot use my phone even after the call is disconnected...screen dosent turn on and the proximity sensor dosent stop
how can I disable this feature so I can still use my phone ?

Suggestion..
Since I am on a different ROM I cannot tell you exactly the steps necessary.. But go to settings>accessibility.. There you should be able to find the solution.. Also there is an option power button ends call..
If your phone is rooted you may use GravityBox to change the way the proximity sensor works..:good:

Yes my phone is rooted..im using stock mmx os ..ive tried the power button method .but it dosent work.. Pls give me a way to disable the sensor... Please

if u use gravitybox, go to power tweaks, enable proximity wakeup

[Q] Black screen while calling

I have OPO with CM12 nightly firmware.
Problem appeared also in CM11S, CM11 nightly
When in call screen turns black and i can't turn it on.
So if i accidently press to call to wrong person, i cant cancell call.
Found temporary fix: swipe over proximity sensor, then press Power button, and it will turn on in couple seconds.
But it doen't work always.

Hello, fréquent problem when you put a screen protector too near the proximity sensor....
Use Proximity Sensor Finder on play store to test it.
If you see 0.0cm every time remove your protector

Hello,
i see 0.0cm every time, but i have no any screen protector or case, its "as bought"
The "sensor last covered" timer resets every time when i SWYPE the green area (dynamic), not over black something near camera, not when i just put my finger there and thats weird.

The issue is modem. Flash the Alpha modem and it will fix the issue. (I'm too lazy to link but just search and you'll find it)

problem solved with flashing CM11s with full wipe including userdata_64G.img
thanks

Sensor problem while calling

Hi,
When we made a call or receive, the screen goes black while we take to our ears.
But, my phone is still black after taking away from ears while in conversation. I have to swipe the sensor area to have a visible screen.
Do i have to replace the sensor or just have to adjust the sensor ?

Hi if you have an EU version the light and proxymity sensor was directly on board...hard to replace...solution for you and others are changing back glue because if you pres top of back glass near the camera the sensors are working....back cover glue wont stick and thats the issue or if somebody replace the lcd there are another issue because the board is too far from front glas and the sensors are not working good...there is a solution uv filter sticker on glas..

Hello,
It is a problem for all Xperia Z# lineup.
The proximity sensor tends to be too far from the glass after some time.
If you have root and Xposed, you can install Sensor Disabler and then mockup the value of the first proximity sensor to 5cm and the second to 0cm. This way, the screen will not go black when calling (it will after a short time but won't be blocked by the sensor so you can re-light it by pressing start button or volume buttons).
If you don't have root :
- go to settings => accessibility and tick "end call with start button" (or something like this)
- Or use headphones !
If you are stuck on black screen, your can force with your fingers on the top right corner of the Xperia Z5 (where the sensor is) to make it work shortly. Or you can press start button + volume up button to reboot.
I hope this will help you !

lol my xperia z5 had exact problem and gues what happend with my mothers z5 LFMAO same sensor OMG what the hell is wrong with Sony...also i always got white dots on the screen after more then a year of usage...no wonder i dont buy Sony phones anymore...my last one was XZ and this one also had bright dots on screen but this time its red color and it can be seen on black background...also xperias overheats very fast and then works slowly after and so on...i can clearly say that after xperia z2 every Sony phone is rubbish and made with poor quality PERIOD

Same problem since I have my Z5. It happens only sometimes and when I clean the sensor (also only with my finger during a phone call) it works again.

Maybe its because of some application which use proximity sensor. Did u install any notification or screen wake app ?

we can asure u that it is a hardware problem.i for example had a two xperias z5 took it to waranty and they fixed the sensor...the other z5 sensor broke 1 week before waranty but my brother couldnt find documents and we didnt send to reapir then...so it is definetly not a software issue....2x xperia z5 2x same issue LOL

Its a sensor problem, the sensor is weak.

Check your tempered glass.. The tempered glass must have an opening on the proximity sensor location.

It doesn't have a tempered glass...

This app fixes that issue (root only) :

Xposed module works. Thanks..
Edit: This xposed module or any other app is not exact solution.
I've solved my problem with removing to screen protector.
There 're dirt accumulation when use to screen protector.

[FIX] Proximity Sensor stuck fix.

Solution on 2nd post.
Hi.
Lately I'm having problems with proximity sensor.
1. During phone calls, after getting phone to my ear, screen turns off and that's fine, but after ending the call screen never wakes up. I have to press the Power button to wake up the screen.
2. After pressing the power button, screen turns off and AOD screen shows up, that's ok, but after putting it to pocket or after covering the proximity sensor with hand and taking it off the AOD screen doesn't show up. It's black screen always. I have to wake up the phone and off for AOD screen to show up.
I was testing the proximity sensor with different testing apps and it is recognizing near proximity but it never recognize that there is nothing near anymore. Ex.: during testing I cover the proximity with hand and it is recognizing it, but when I take my hand off, proximity sensor is still saying there is something near.
Problems started some time ago occasionally but since yesterday it always like that. It started on Android 10. Downgraded to 9 (ver 1.9 from zte de site) and it was ok for 2 weeks like. Yet it started to get stuck for good, even upgrading back to Android 10 (v 2.4) didn't help.
I looked where the sensor is, left side from earpiece and I swear I could see some dust under the glass, but since the phone is waterproof (IP68) how there could be any dust inside? I was shaking the phone to get rid of the dust from the proximity sensor to no avail, sensor is still stuck.
No glass protector applied, no any cover.
What do you guys think? Should I get RMA for it? Or s there anything can be done? Anyone else having these problems?

FIX for proximity sensor getting stuck/not working properly
Found fix by myself.
Proximity sensor in my case got some dust in it or it de-calibrated itself. If proximity sensor is broken on hardware level, probably this solution won't work. Yet, you are free to try it anyway.
If your proximity sensor de-calibrated somehow or got dust on it and it is misbehaving, do the following:
1. Go to Phone app, enter:
Code:
*983*673636#
to enable EMODE (self-testing app), toast info about enabling EMODE will be shown,
2. In the Phone app enter:
Code:
*983*0#
to start the EMODE, menu for various test will be shown,
3. Go to SENSOR TEST
4. Cover the proximity sensor with your hand ? (upper side of the phone ), test will say something like PASS in green color),
5. Swipe to the bottom of the menu, place your phone flat on the table in not so bright environment and hit CALIBRATE.
6. Your sensors are now re-calibrated and proximity sensor will work like new, even if it is dusted.
7. If you want to disable EMODE, go back to Phone app and enter
Code:
*983*2567336#
but refrain from doing so, if you want to run EMODE again in case of any of sensors misbehaving again and wanting to recalibrate later.
That's it, my proximity sensor is working again like new.
Sidenote: if there is dust inside the phone, phone is not so waterproof (IP68) after all. Just be careful with water with it

Hey! I have the same problem with the proximity sensor and even though I did the same that you say, nothing changed.
Do you any other solution?
