Hey there, I have an issue with malfunction of proximity sensor on p30 pro after screen replacement. The replacement has been done professionally, I’m very experienced and I repaired this device many times successfully. The malfunction of the proximity sensor is not caused by some protection glass or software issue. Phone has been updated and resetted. Also the Sensor is working generally because after putting it to a different p30 pro it worked just fine. I‘ve tried to read some info about the sensor with some diagnostic apps, there is no function of the sensor what so ever. Mainboard is also working because i putted it to a different frame and it worked just fine. Any ideas how to solve this? Thanks for your help
Did you have any luck with this.. I have an identical situation. even bought a new proximity and nothing doing.
I've thrown the towel in and buttoned it back up now.
Cheers.
Yes I was successful. Most likely the issue is caused by the missing of a little piece of foam between display and frame.
Oh, I transferred that piece between the cases.. maybe it's damaged. I'll check into it.
Thanks.

Hello.
Can you please explain what you mean with little piece of foam?
Thank you
This piece has to have the right size, shape and especially thickness, otherwise proximity sensor will fail

I've had my Diamond for about a week or so now and after a few days I noticed a relatively minor cosmetic issue. As seen in the pics below, the button pad on the bottom is slightly raised on the right side. The buttons still function as normal. It's not really noticeable when you're holding the device during normal usage, but pretty visible when looking at it from certain angles. Are there any decent disassembly instructions/walkthroughs for the Sprint Diamond floating around? I found the service manual for the euro diamond, but not the CDMA Sprint version. I can probably do it myself, but it always helps to have a backup in case I forget how to re-assemble certain parts. I'm not sure it's something I really want to bother sending the phone back for or anything. I can live with it if I can't fix it myself.

Diamond service manual
Hi if you PM me your email adress I will email you the service manual.

I've got the normal Diamond (squared version) and it also has the this problem since the very first day, but on the left side of the panel (the home button). I checked a friend's diamond and it had exactly the same thing on the same place.
Anybody else?
I somewhat fixed it by just fabricating a small washer (out of a twist tie) that goes under the screw on that side, so when you tighten the screw down it pulls the button pad inward a little. It's not perfect, but much better.

The edge under the power button looks pretty rough also.
The One mini M4 suffered from this and has cracks all along the outside plastic band.

Thank you mate I know that problem. I've had like four or five Mini's and they all had the exact same issue and got replaced over and over again until I decided to give it away and upgrade to the bigger sibbling.
I stil have no clue how to repair this frame.. A friend has had the same problem and his powerbutton broke. And without this button the phone is kind of useless..
Hi, I've got a problem with my S3 LTE. I have changed full set in my phone. Connected it to the motherboard and there is a problem with touch sreen. Once it works, then it suddenly stops and doesn't work. I tried to change ROM, I have contacted seller of set, because thought that is faulty. He sent me a new one and it is the same problem. When he got the package with that first one, he wrote to me that it works perfectly with his phone. After few weeks with this problem I saw something new today. At the time, when I'm pressing motherboard in red selected area, touch screen works! It is not about the LCD flex, because when try to push this flex it doesn't help me. It works always when I press here, like on image. What is an issue? What could I do? (sorry for my English, it is not perfect)
Here on this picture it is i9300 but it's the same place as in my i9305.

It seems that it is problem with cold solder joint on motherboard, that is my opinion. When I heated it by hot air in 100° C for a minute touch worked for a few hours. Is it possible to repair? What should I do?

What's on the other side? I mean in the exact same area.
Right bottom corner on this two pictures.
Anybody got any ideas?
Hi All,
I have recently replaced a broken LCD display on my Galaxy S III Mini, buying a full new kit (LCD+Touch+Screen).
All works fine, except the proximity sensor that is always "closed" as if an object is covering it; so, when you make a call, the screen become black and you can't stop the call.

The seller says (without taking a look to the phone) that the problem is on the motherboard, but I had no problems before the screen replacement.
So, my question for you (that are more expert than me) is: the proximity sensor is embedded in the LCD+Touch screen?
What do ou think about the seller statement?
Thanks for your support.
Clean the sensor

I had this same problem with my s4 and the solution was to open the phone and clean the sensor good, I used double sided tape to remove the particles and 98% alcohol to clean the lence, so the problem is not the motherboard don't worry... sorry for the spell mistakes. You know English, Macedonia you get it...
Did anybody have this problem with X2 Pro touchscreen being way too sensitive? Like you can use it without even touching the screen, just hovering the finger ~1 mm above it.
At first I thought it could be because of the static on the stock screen protector, but it's actually even worse without one.
The difference is quite dramatic when compared to my old Nexus 4 (where you need to firmly press to register a touch), but not so much compared to Xiaomi Mi9T (which also feels way too sensitive, just not as quite as much as my X2 Pro).
Doesn't lead to ghost touches or anything like that, but scrolling with one hand is rather uncomfortable as it feels like your thumb is sort of "sticking" to the screen.
It almost seems like there's some sort of a glove mode on. I've looked through adb settings (currently using RealmeUI c26) and found these:
Code:
glove_enable=0
oppo_glove_mode_enabled=0
synaptics_glove_mode_enable=0
Unfortunately changing them does nothing.
Can somebody try this test for me:

If you put a thick stack of papers (e.g. 26-page Realme Quick Start Guide) between your fingers and the screen, pressing hard does it register touches? Mine does quite easily.
Not sure if it's supposed to be like that or perhaps I have a defective unit. Or maybe this is working as intended, made with the assumption that everyone puts thick protective glass on top?
Can anyone help me this? Same thing happening on my k20 pro.
Also can me tell me the commands you used to get the glove mode options?
