Hey all,
I'm having a few issues with my multitouch. Firstly using a multitouch app it picks up all of the fingers a different inputs but they flicker unless you're moving your hand around, so it's impossible to use it for games and such. I'm fairly certain that this is a hardware issue. Although it doesn't seem like it's completely broken as I can still register multiple touches, its just impossible to have continuous multiple touches. Any idea on how to fix this?

It should still be under warranty if you haven't rooted it. So I guess you should take advantage of it.
Sounds like the calibration for the active digitizer for your device needs to be recalibrated.

There are some apps for it.
I tried a few of these apps to no avail. I'm going to have to assume its a hardware issue. unless theres any more ideas.

Most probably it's a hardware problem.
Could it be that it's a lose connection? Or do you think the whole screen and digitizer assembly will require replacing.

Enter *#*#2664#*#* into the dialer to run the Touchscreen diagnostic test to see if your device's active digitizer is really to blame. I don't know the code that will recalibrate the active digitizer of your device. You would probably have to send your device to Honor to get it recalibrated.

This code doesn't do anything. I'm not sure Huawei will be willing to do anything as I have unlocked the bootloader for root.

Hey there.
I bought a Surface 2 Pro 128gb last week. Today I encounter a "big" problem: neither the touch or movement of my pen are not recognized anymore.
I've already tried to uninstall the second USB INPUT DEVICE under HUMAN INTERFACE DEVICES in the Device Manager and it did not solve.
Did that happen with anyone of you guys??? Any ideas??

Have you tried the refresh?
Also somewhat obvious and I assume you have tried but best to cover anyway, you havent simply had the tip fall out of the pen have you?
Otherwise it might be time for an RMA.

i've already tried the refresh too .. I've tested the pen on another device (galaxy note) and it worked well ..

If the digitizer is dead then you should be able to get the device replaced under warranty.

Not only will they replace it under warranty, but when I took my SP1 with a dead digitizer into a Microsoft store they let me pay the $200 difference and get a SP2 as a replacement.

Are you jokeing? O_O My rear camera is dead, but i need my SF for work, so i didn't consider sending it back so far (as i don't really need the cam anyways)...
Anoter problem is: i didn't buy my SF in a MS-store... Do you think i can get this offered at the online store? (as there is no Microsoft store in my country atm...)
Maybe i'll give them a call tomorrow i'll let you guys know what they said

Yes, I'm under warranty but I've bought the phone from China and I'm from Italy, only the ship cost will be more than the repair.
There's no place to repair a china phone here, nobody even known the phone
But it's a problem that has a lot of OPO and the manufacturer said that, they're good enough and, even N% has yellow screens...
But I'm really not happy with this phone, not only for the yellow line.
There is no way to fix it, with usage and time it gets slightly better. 99% of phones have this, so you should not have bought the phone, if you think this is a deal breaker.

I didn't know that this kind of phone has this kind of screen. Obviously I never bought a phone with this defect.
I really never bought a phone even if I had known the state of Cyano 11s.
But it'd definitely my fault.
Thanks for the answers.
There's an entire thread dedicated to this. Try using a UV lamp (found at a nail salon) for ten minutes with the device turned off.

I have never had that problem
The display stopped working 2-3 days ago. On booting i can see the google logo for 2-3 seconds before the screen goes dark. The phone works and i can hear dings of messages, but i cant access any of it. Once i kept shut it for a day i was able to see the screen for 10-15 seconds( i used this window to remove the screen lock so that i can use the usb transfer ). Now keeping the phone shut for long duration has no effect.
I can see the fastboot screen but not the recovery screen throught it.
I also bought a slimport so that i could see the screen on my pc. It works (not for the fastboot or recovery), however the touch doesn't work and the volume and power buttons response is too sluggish. I can connect the mouse but it is of no use as i can't see the screen on PC and use the mouse at the same time. I tried adb ( i have no experience of it ) but i cant touch the allow pernmissions key on the screen for the above reasons. Also what advantage would adb be in this case?.
Any advice ?

Oh, you mean sending it to LG for servicing? I am a bit hesitant since i have cyanogenmod and also am in india and i doubt they will give a replacement. I think going back to stock rom and then sending it for repairs might help but i have no idea how to go about doing that in this situation.

Its all done via fastboot or lg flash tool. Probably the latter is best for you. Have a read of the guides in my signature

Same issue I had pretty much, it died about 2 months ago. I was still able to copy all of my files, phone worked perfectly but the screen was black. Had it replaced it no time. Is that by any mean a 311k? I've seen another thread like that pop up lately.

I don't know yet, I'm just trying to figure out whether it's a particular batch that started failing or it's completely random, just curious. The two replacements I was sent were 403K. Build is perfect, but they both had some light bleed issues. Looks like every batch comes with some good and some bad, QC definitely hasn't been too great on this phone.

They're not really built in batches. Manufacturing was continuous. They just changed the serial number every time the month changes so I dont think this would actually mean anything
I know but I'd still use it as a milestone more than anything, I mean there have been some differences in the units (eg bigger speaker holes), this way it's easier to track them along the timeline, because they definitely do change something in the manufacturing process from time to time if they have to make up for issues or something. They also did it with the N4 if I remember well.

Speaker holes is a bad example because even the latest built devices it was still a lottery whether you got bigger or smaller holes. That's down to what you mentioned earlier, QC

I was able to unroot and flash the stock image. The problem still exists though, so it has to be a hardware issue. Fortunately the phone is still in warranty.

It could be a number of things. You could try recalibrating the firmware for the touchscreen. There's a thread that talks about replacing the LCD. Anytime you replace the LCD you have to recalibrate the firmware for the new screen, so they also talk about recalibrating the firmware. Just do a lot of reading and you can find it. Sorry I'm on my phone or I'd link you.
Alright, so currently im dealing with some Multitouch issues on my Pixel 4a. The repair place i went to UBREAKIFIX said they'll have to do the whole repair they did preciously again and charge me (because of 2 small dents at the side of the screen). Would not recommend. I wanted to get a poll of everyone with this exact issue Here is some steps to test:
1. Enable Developer Options (Go into build number click however many times and get developers options
2. Go to Developer Options in System settings,
3. Scroll down to Input and enable "Show taps" and "Pointer Location.
4. Put two fingers down and see if multiple pointers are shown (If not, Multi-touch does not work)
Also some other Notes:
Downgrading to Android 10, Makes multitouch work for some reason :/
Also would like to know if you've gotten your phone repaired before.
Any help figuring this whole thing out is appreciated
Can I ask what was the repair they did the first time to fix your touch problem?

I honestly cant say if its the hardware or software, maybe it might be a combination of both? I'm not entirely sure, however downgrading to android 10 from googles flash tool does seem to have it work. I had what i would guess is a full screen replacement from UBREAKIFIX, due to shattering the entire screen. Honestly, spending 140 dollars just to see if it might work is not worth it to me, so I'm really not sure what to do.
Even doing it yourself the cheapest I've seen a screen is 110 from AliExpress, which I don't get because I just replaced one on a g7 moto play for 20 bucks off ebay

I have LineageOS 19.1 here. So android 12. i'll try that android 10 approach
I can confirm now that downgrading to Official Google Pixel 4a Stock Rom Android 10 fixed the issue. I try to go back to LOS 20 now and see what happens.
PS: Using internal updater to update to Android 13 broke it again. Taking the long route now.
PPS: That chromium based flash tool is really handy. Would be awesome to have something like that for LineageOS.
PPS: As soon as I install anything above Android 10, multitouch stops working. I'll sell this stupid thing as is (will let te buyer know of course). Its a shame.
