X1 closes on any hit or shake

Well, I have a problem which makes the X1 practically unusable. Everytime I hit it with less or more power, or when I move the slider a bit faster, and even when I press on the slider in the opposite direction when closed (like from right to left) it turns off... I got it apart and cleaned every part of it, but there is no improvement.
I can't mention a certain moment in the past from where it started. All I can say is that I have dropped it twice and broke the plastic parts, but the problem appeared some months after, so this may not be the main cause. Also I took it apart once (before it started to turn off suddenly) because the screws that were supposed to keep the slider on it's place went out.
I used it for almost 2 years, but I don't have enough money for a new device (nor a second-hand one like HD2), so if you can even suppose what's the problem, please tell me.
Later Edit: Another thing I noticed after pressing each part of the X1 is that the problem is somewhere in the upper part (near the camera... I noticed it when I tried to pull the stylus and when I pressed the volume buttons...

I'll take the inside out again, now that I know in which side is the problem. I'm on my backup phone right now, so I have nothing to lose... I still think is something wrong with the battery contacts or somewhere near those, so I will check again... I'll tell you if I find something.

Looks like a flex cable problem.

I checked the flex cable, but nothing is wrong with it... It may not be well fixed on the mainboard, and it totally shuts down, not only screen/buttons problems...

Left side touch screen misbehaving after wet

Hi,
Last week I used to be outside with much rainy condition.
Though it never got totally under water, many times it's screen got wet with substantial rain drops.
Slowly, phone started misbehaving with following symptoms,
1. Around 10% of left side of touch screen doesn't show response. I enabled show touches from developer option and when I try to touch left side, say "a" letter in keyboard, it doesn't show touches and pointer jumps immediately to left edge.
2. Many times, I am not able to unlock phone as no touch are detected.
3. After unlock, many times though I am not touching phone, it shows couple of pointers (I enabled show touches in developer option to trace this) on left edge. It keeps moving resulting in erratic behavior, say screen zooms in and out, some icons clicked automatic, deleted automatic etc.
4. Sometimes I noticed that capacitive buttons are also not responding.
For all above, I have to off (not complete switch off)and on the phone. After few attempts, it becomes responding except point 1 above.
I have reflashed ROM (Vivikat) just to ensure it's not software issue.
Now it seems hardware issue with following two possibilities...
1. It's matter of some moisture in phone only. I have to try hard to dry out all moisture and phone will become responding.
2. Digitizer has some issue and may call for replacement (I don't want to do that...:crying.
Can you guys share your views/experience and advise?

I just had touch screen issues but not with water or rain. It was the CPU. Almost whenever I overclocked it, I had touch screen issues. Both misbehaving and not behaving at all. Change the CPU frequency and restart the phone and see what happens. :good:

Thanks for your reply.
I have never overclocked my device.
However, I tried to underclocked it if by any chance, it can solve the issue.
But issue still there.
A small portion of left column on touch screen seems not responding or giving erratic behavior.
Does, water can damage digitizer to that extent that can not be recovered even after drying
Or, I should keep hope and wait more before I go for digitizer replacement

If the digitizer is damaged, it is probably done. But if you can open the open, check the digitizer and see if there are any things stuck on it. My recommendation: ask an engineer to open it and clean it with the special spray they use to clean electronic parts. Maybe the water has had only a side effect and it will be fixed by cleaning the digitizer.

proximity sensor issue?

Anyone else seem to have a problem with the ambient light/proximity sensor on their N6? I've noticed that a lot of times when i make calls, the screen won't shut off when i put the phone to my head... often with that resulting in my cheek touching something, and the person on the other end not being able to hear me. If i leave the phone at an angle against my ear so my cheek doesn't touch the screen, eventually the screen will shut off, but won't come on when i take the phone away from my ear, resulting in me having to press the power button to turn the screen back on.

Had that happen to me yesterday ... Rebooted and it hasn't happened today.

I'm having a issue now. Phone call comes in and screen stays on. I did a reboot, factory reset even installed custom ROM. It was working the other day. Anyway to calibrate this thing? Or do we have a bad sensor.
Also now my phone won't rotate screen.

Do any of you happen to have a screen protector on? As there have been some users that have been reporting issues with certain screen protectors. I believe most are tempered glass protectors that are the cause of the problems.

I took mine off and still nothing.

Did you try going to settings , accessibility , power button ends call, toggle that on and off.

We own two new Nexus 6 devices that are rooted and decrypted. We have the same issue where the phone screen stays on during a call. Rebooting fixes for a short period (hours or so) but the problem comes back. Other threads show this to be an issue with other phones (nexus 5) with Lollipop. Not sure of a fix. These devices are only a few weeks old so it is not a dust issue.

Having the same issue that just suddenly started. Rebooting does not seem to help.

Happening here too. Frustrating.

My screen turns off when taking the phone to the ear but it doesn't turn on again after i take it away from my ear.

It's pretty bad on my phone. The screen turns on when I am on a call making the notification bar drop down. Also, the phone doesn't wake up when I pull the phone away from my fasce 80% of the time. When I am on a call the phone randomly vibrates like I am getting a notification and when I look I have nothing. With all of this going on, making phone calls on this device is a nightmare.

Restore clean wipe did nothing.
nexus 6

The below mentioned fix is for brand new Nexus 6.
Did you try going to settings , accessibility , power button ends call, toggle that on and off.
After completing the above mentioned step. Reboot your phone and try making a call. I hope the issue get resolved.
I tried this step on an unrooted phone, which was recieved just yesterday.
I got this fix from some other thread.

What app

Orzly works fine... It doesn't cover the sensor. The Slimwrap orange vinyl (leather) face was a problem for me, had to enlarge the cutout to get suitable performance. I believe the sensor is longer than it is wide, the opposite of the factory cutout? It frames the face of the phone nicely with this screen protector on and I didn't want to take it off. The 24mm added height changes the profile of the phone alot, it no longer rests on the speaker bars/guards. This must also have effected placing the wrap on as well. The larger cutout box for the sesnor is a detractor, but the sensor works 100%. This is good , as it is my intention to run nekid with this phone but its size precludes using a case with any of the pockets I currently own.

Thanks I was just having a crazy time trying to install the front, similar case (glass protector in front) and ended up cutting a hole for the proximity sensor about 2 times the factory height, everything (seems) normal now. I used this program to help make the minimum cut, and align correctly. Did you run into any issues with the thin left & right vertical part of the front cover? Mine seems to "wrap" around the glass protector, not sure if it will stay there though

Proximity sensor LED NOT blinking in MOTO X

Hey Everyone!
I am new to this site so pl bear with me if I am posting some wrong thing.
Got MOTO X Verizon running on HSPA in INDIA. Everything seemed to work good.
Suddenly after 3 days of normal use (no dropping, no dumping, no water damage), screen started to garble at uneven intervals.
With all the pain to search for the problem all over the internet I at last (i think) solved the problem.
For this I had disassembled the screen and motherboard and just pressed the golden sticker (above the inter-connecting cable on the back of the screen)
Screen works fine now, but I guess I screwed up the proximity sensor mounted on the motherboard (seemingly irreplaceable.)
When calling the screen goes black etc...( i know this issue has been cited many times...mine is different I believe)
This was working when i got the phone (waving my hand always used to start the active display).
I checked my settings for Active display, got numerous apps for the the proximity sensor testing. [ Phone Tester shows proximity FAR and does not change that value whatever i do; "Proximity Sensor Finder" shows 3.0 cm last value and does not change ever either]
Then I tried everything from the rubber gasket installation to a hard reset, factory reset and what not.(thanks to tonnes of websites and people helping all over the world)
NO LUCK!
I also noticed that the LED beside the sensor used to blink which has actually stopped. LIGHT sensor and all others are working nicely.
This is where my issue lies :silly: : " Has anyone got this type of problem? Has the golden sticker on the right top corner on the back of the screen anything to do with the RED LED of the proximity? I tried all dialers, all possible ways to bypass the Proximity but invain. I am not wishing to root this phone and I am not good with coding either. Can this be a software issue? (running 4.4.4).Is there a calibrator out there to rejuvenate my proximity?
PLEASE HELP!!
For the time being I am using bluetooth headsets (where the screen remains open).

In Kitkat?

This feature is gone with Lollipop though...
And I read you're on kitkat, but really there was a LED blinking there???

I own an xt1060. There is an LED there, but its always been less than useless for me. It never turns on. Ever. Not for calls (missed or otherwise), notifications, or charging. I've often wondered why it's there.
I can make it work in Cyanogenmod. Any stock ROM renders it useless.

when you said you checked gasket are you referring to the tinny black rectangle gasket around the led and prox censer? when i first starting working on the x i had smiler issue, the little gasket fell off and i did not notice it

Exactly the same small thing I m taking about.. God knows I dropped it or not... But when I opened it for the 4th tym... I noticed was not there.. Then I did not get it anywhere in sale and so replaced it with a small white rubber piece with 2 similarly cut holes. No luck. Where did u get it from?
BTW I believe it will make the proximity work only if the led on its left side blinks. That works like a transmitter and receive I guess.
My led won't even flash for once..
I plead to all the genius developers to device an app for proximity bypass.

I did replace it with a white rubber gasket almost cut into same pattern after an exhaustive search on internet for its replacement. And I am still stuck.
Also what I believe is that if the LED does not transmit at all, How is it going to help any way?

You seem to not understand that even you have cut a replacement gasket, it may look perfect to you, but it can easily block the proximity and that's about it.
You should try with original one, then start pulling off conclusions if the sensors are defective or not.
Why don't you run a dry test without the gasket?

"Dry test?" can you please elaborate this?
BTW I had tried using without the gasket too. Same values on the tester apps.
If sensor is working each time the value should change at least a bit when open to light without gasket.

By dry test I meant to test it without putting the display/frame over the board and test it that way. If it's not defective you should get proper readings off it.

Disabling Proximity sensor - Nokia 7 plus

Hi All,
I am using Nokia 7 plus for past 2 years. Andorid 10 with Nov security patch. Recently, my proximity sensor stopped working and I am not able to use phone any more (due to black screen during calls). I even root my phone and installed edxposed framework for disabling proximity sensor but no luck. Even sensor disabler not working for me. Any suggestions would be much helpful as I want to use this phone badly

I have same problem (stop working after lcd replace), try more solution, but at end i find one "working"... In Developer options enable QuckSettingsDeveloperTiles/SensorOff, this add Sensor tile to top pulldown QuckSettings menu, before call must you manually enable it, after call disable (because sensor off disable all sensors and also camera ;-)

Yeah, I have been using it. Problematic when attending calls in Skype which wont work unless you switch again. Thanks anyway

In my experience, proximity sensors don't stop working, they just work all the time! Often there's a small rubber gasket which separates the UV LED from the sensor. Can be lost when replacing a screen - I did this myself on a Moto G. Screen would go black in a call and couldn't be unlocked. I found the gasket on the floor, replaced it and this fixed the problem. Replaced the screen on a Nokia 7 Plus recently, same problem. I couldn't find a missing gasket this time, but glued a small piece of rubber between sensor and LED and this fixed the issue. Had to experiment with the size of the rubber piece to get it working properly. I think some of the UV light bounces off the back of the screen and is picked up by the sensor , if this piece is missing. My $0.02 worth...

Guys, I am frustrated with proximity sensor of my Nokia 7 Plus, as soon as I call, screen goes black.
I could stop it by enabling Developer Mode and disabling sensors, but this disables all sensors not proximity, and my camera stopped working.
Can I just remove it from mother board? any way to disable only proximity sensor?
Thanks in advance.

If you've had the screen replaced, I think the rubber gasket separating the IR LED and sensor has been lost. Seems to be a common cause of this kind of problem. Cheers

I guess just the screen turning off during a call. But removing it may damage some other component, I guess. I also wonder if the screen stays off or on permanently if the sensor is removed. If you're taking the screen off anyway you could just try my fix of glueing a small piece of plastic or rubber between the sender and receiver, has worked for me and is still working. But this is just my opinion, all the best in whatever you decide to do. Cheers

Ok Thanks, I shall try it.

One more question
Is there a way to disable only proximity sensor through OS/App? This will save my effort to remove it from board and possible damage to board.

Am working on another 7 Plus which has the gasket fitted to the proximity sensor and took some pictures so y'all can see what I'm talking about. First picture is of the gasket, second is the sensor without the gasket. Cheers

Just checked in to this forum for give Gastrocnemius a big "Thank you"!
We have a Nokia 7 Plus with the "normal" USB connection issue.
Send to repair to an independent repair station (so not Nokia), who offered a good price.
When it came back it looked fine, charging and fast charging was possible, we have been happy.
Until the first call... Black screen with dialing.
A short search showed: many problems after an update, looked like software related issue with no solution.
Shortly after the new USB connection was faulty again.
So the phone went into a drawer and replaced with a new Nokia.
Now my old Redmi 4 is too old and some for me important apps will not work with the "old" android.
I remembered the Nokia 7 plus and started to repair the USB board, also as a trial if i can handle mobile phone repairs for myself. Well, cheap USB board found, change successful... not! Broke the Display (stayed black after assembly, board from display got hot, probably cable broken).
Ok next step, new display, screen works and and charging repaired on first view.
Function check: black screen during call. Tried several proximity fix tools without success.
The app Phone Check clearly identifies as proximity sensor as "close" / near, no change.
The change to far came only when the display was way to the side. So, the sensor is working, but the function close far is not working.
After weeks I discovered this fred! Gasket? Which gasket! There is no gasket! Check with several videos on YT, yes, gasket identified!
So I tried the mentioned fix rubber band but was not able to get it working.
Then I looked for a gasket online and found one available for the Nokia 2 / TA 1007 on EBAY for a couple of Euros and ordered it for giving it a try.
I just assembled the gasket.... the 7 plus no works like new!
So I'm assuming that during the first USB-board change the gasket got lost and the check by the repair company was only performed for the charging and no more checks for the rest or they didn't care (ASUMING!)
Long story short:
If the gasket is missing you can use the one from the TA-1007!
It does look a little bit different than the above gasket but mine worked. No further assembly from the phone is required, just slip it over the sensor (make sure that the big hole is left, seen as microphone is up and sensor is up left [don't know how to describe better]).
Thanks again for the hind to the missing gasket.
Best regards from Munich,
Thorsten
