Hello Everyone. What I'm about to write might be a bit tricky and complex, so thank you if you'll follow along.
Unfortunately, I dropped the phone into water couple of weeks ago (I know, how dumb...). I let it dry 3 days in rice and Silica gel. After that, I tried to boot it up and it worked, but after couple of hours the touch screen was not responding anymore. I rebooted it and worked again, but lately failed another time.
I tried to let the phone standing up for 3 days, and it worked again perfectly. But as soon as it lies flat horizontally, the touch screen stops working.
After several attempts, I figured out that there might still be water in it, which reaches the motherboard/top of the phone when it is horizontal and messes up with the screen.
However, just out of curiosity, I tried to change ROM and noticed the following:
1.MIUI Global Official: Phone works perfectly, even after lying horizontally. However, everytime something full screen is running, touch screen stops working.
2.DotOS/Lineage/AICP(unterwelt) (All based on Nougat): Phone works, but touchscreen fails after it lies flat.
3.Factory Kernel/ Voodoo: no differences.
So, do you think the problem is in the Hardware, or Software?
Do you accidentally know any good seller of LCD/Touch-screen replacements?
I'm looking forward to buy a Redmi note 4 (if I find any, since there are very few on the market and there are no redmi 4 prime anymore), so I thought this topic might be an take-off for some interesting discussions/opinions.
If you arrived here, thank you very much for your time and hope you can help me one way or another.
Best,
G.
PS: I tried all possible paths while changing ROM/Kernel (Clean and dirty flash, no/formatting data, reinstall TWRP)
In case might be useful to someone:
I opened the phone, use a hair dryer (cold air, not hot) for couple of minutes and now it's working perfectly.

Guys,
Need some help here. A couple of days ago I spilled some water on the navigation buttons on the lower part of my Hermes that was working ok just fine for the last 8 months. Cleaned it up with a towel and everything looked ok for another 3-4 hours when the touch screen graduatelly stopped responding, now is dead. I took everything apart and cleaned all the connectors however I still have the same problem, no improvement of any kind.
I've seen in the forum that some other people had this issue, what I am curios is to hear if anyone was able to fix it. Thinking of replacing the digitizer/lcd..will this fix the problem or there is some other screen driver chip that may be damaged?
Thanks
Hey fellas ,
I cracked the screen of my Nexus 4 and installed a replacement.
It's been approximately a month now.
Sometimes when i restart the device the touchscreen doesn't work and i have to restart it again and again until it starts to work. I noticed that when i put one of my fingers anywhere on the touchscreen (around the display not the bezels) , it starts to work and recognizes only one finger whereas i have two on the display , when i remove one the touchscreen doesn't work again. So , i have to restart sometimes just once sometimes a lot of times to get it to work.
I have intricate knowledge of the touchscreens and how they work but i can't put my finger on this problem. It looks like a capacitance issue because when i put two fingers it recognizes one , sometimes it needs 3-4 fingers on the screen to recognize only one.
My original one still works but has a bad lcd (colors are all messed up) because my clumsy attempt to repair it resulted in failure , i tried it and the original one works without a hitch. The only thing i haven't tried is to remove the battery. I installed everything when the battery was still on , the screws are too flat for any of my screwdrivers. But i hotplugged the original one and it worked. So , that's probably not the problem. I just shut it down with 3 of my fingers on the screen. Waited for it cool down and then reopened it , it worked. Whether this is a thermal issue or not , it needs further testing on my part. I'm currently not willing to find out because i just had to restart 5-6 times to get it to work and i need it to work constantly for the next couple of days.
I can't return this because i already got a full refund and the seller didn'T ask for a return , he said to keep it. He advertised it as genuine but it was aftermarket. So , this assembly was free folks. I broke it and got away with it. We gotta get this working without any problems so i can sell it when nexus 6 comes out.
disconnect touch,power on phone without touch,disconnect battery.After that connect touch and power on your phone:good::good::good:
same problem here...
And I see the problem at a lot of other forums too... no sollution... have you found a workaround?
I'm too late to ask for a refund...
Hello.
Firstly I would like to say that I am well aware, that there have been threads regarding this problem, however, none of them were of any help. Did not help on solving the problem or even determining the cause. So here is the deal.
My nexus 4 is nearly 2 years old. It has had some tumbles, one of them was in January and caused my screen to crack. The touchscreen was unresponsive, but picture was showing just fine. I figured that I would change the screen and digitizer all together. And that is what I did, and it worked beautifully. I was quite happy to have my phone back, and it was working like this for nearly four weeks now with NO problems, what so ever. This evening has been a bit different. My touchscreen has been going crazy. Sometimes it recognizes the touch, sometimes it doesn't, sometimes it registers the touch in a different area and the phone just goes to **** all together. The phone hasn't suffered any damage lately, no falls or anything. As You can see in the screenshots, the screen appears to have a dead zone, right in the middle. Also, the phone lags quite badly, when the touches go crazy.
Any help would be greatly appreciated, I would really like to avoid spending any more money (that i do not have) on spare parts, if the phone is unusable anyway. Some of the things I tried, that were suggested as possible solutions :
Factory Reset (both from booted phone and recovery mode) And the touch problems got even worse after that.
Clearing the cache (recovery mode as well)
Opening up the phone and checking the connections (which seem to be fine, since)
Hopefully You guys can help me find a solution, that wouldn't require me any more spare parts, cause getting stuff from ebay is not easy in my country. And I cannot even dream about a new phone, firstly cause I do not have any money, secondly - I love my nexus4, I am very used to it. It'd be a shame to let my friend gather dust on a shelf.
EDIT - At some point, the dead zone was non existent, as You can see in one of the screenshots I uploaded. The phone was opened up at the time, the dead zone was gone, but it was back after some lag.
Anyone having touch screen only issues? There's not a single crack on screen, I've always treated the phone very well.
I'm thinking whether I should replace the whole front, but curiously only my touch screen is not working, display is OK and works well using SideSync. Also, the entire touch screen starts working at random times (I haven't been able to figure out the conditions, it's not hot/cold or pressure; I've used a hair dryer, a refrigerator and heavy items on top of it).
In fact, it worked for a month after it started malfunctioning (initially it didn't work for some hours, and then worked again). But now it got worse again. It's not software as I've tried XtreStoLite and now I'm back to stock. Should I replace the whole thing?
Oh, I have the G900H.
Sounds like a bad digitizer. It would be wise to shop for a new one before it goes out completely.
Hi,
I own an Oneplus 2 for over a year now, in which I had to replace it's display two times . The first time I ordered a new display+digitizer assembly and replaced it myself, went great and everything worked fine. The second time was a month ago, I ordered the exact same display from the exact same seller on Ebay and did the replacement. I tested the display before assembling the Phone and it worked as it should. But an hour later when the phone was already assembled I discovered that the touch screen was completely unresponsive
After some trial and error I came to this conclusion:
the problem seems to be caused by applying a mild pressure anywhere on the bottom right quarter of the screen
the display does always respond when I hold my finger on it (with or without applying pressure) for about 4 seconds, then it sees my finger and I can swipe around (while still holding it down)
if I try the method above a few times, or let the phone rest on a desk for some time, the problem disappears and the touch screen works fine again.
So far, it looks like a hardware-issue, maybe a faulty screen or I messed something up while replacing it. But it gets weirder:
My OP2 is rooted and at the moment of replacement, it was running Lineage OS 14.1 (nightly, 2017-03-30). And when I wanted to update that to it's newest build, I realized that this whole touch screen problem doesn't exist in the TWRP recovery interface. It worked perfectly fine even when I tried to recreate the problem by applying firm pressures on every spot on the screen. So this made it look more like a software-issue, however the update of Lineage didn't resolve it and even restoring my backup of OxygenOS 3.5.6 didn't help.
I found this XDA-post about having firmware issues for the touchscreen with Android 7, but running their fix did not resolve anything either.
Right now my phone is pretty unusable since having it in my pocket is creating the problem. :crying:
Does anyone have any ideas of what the exact problem could be? Or anyone having similar issues? Why is it that there is no problem at all when booting into recovery (TWRP)?
It looks like loose connections between the display and digitizer.
After all it was a hardware issue. I disambled the phone again and after a lot of trial and error I found that there was something that came in contact with the back of the lcd that must have created a short cicuit or something. I placed a thin sheet of paper on the back of the lcd to prevent this and it all worked again! Still weird though that it didn't happen in TWRP.
