been through several reboots and taking battery out and resetting the phone. cant figure out if its hardware or software related thats making the touchscreen stop working. i tried going back to Winmo and still touchscreen isnt working. i think the phone got a little wet the day it stopped working, but was in my pocket all day. (not drenched... my pants were just damp). anyway when android boots up i get this...
no irqf_trigger set_type function for irq 190 (kaisergpio)
msm_i2c msm_i2c.0: error waiting for notbusy
would this be something that i could replace and it still work? ive tried taking out the battery and holding down the power button to discharge the phone compeletely. i am running dzo's froyo and the latest 7_26 kaiser nbh. i removed the overclock and nothing seems to help. this is the part i was looking at (http://cgi.ebay.com/HTC-8925-Tilt-TyTN-II-Kaiser-LCD-Digitizer-Touch-Screen-/170469159819?cmd=ViewItem&pt=PDA_Accessories&hash=item27b0c0f38b)
any help is appriciated
It does sound like a touchscreen failure, and moisture is the biggest cause of mobile phone failures, believe me, my workplace can get as many as 230 mainboards a day from repair facilities, most are obvious liquid damaged, and we wash them, dry them and send them back.
However lcd's and touchscreen are a totally different matter, you cannot wash them, that destroys them, so the only thing that can be done is replacement usually.
The link looks to me to be a full kaiser replacement screen assembly, and at a good price too, but be aware that the problem may be the connector itself, where the screen joins the flexi, since most often moisture affects these rather than anything else, due to the small gaps between the pins which are perfect for shorting out when they get wet, if you remove the screen carefully, and closely examine the connectors they may have a fine greyish furry coating, if so a light brush with fine bristle brush should get rid of most of the short, allowing it to work again, if you are going to be disassembling the phone to fix the screen, it's worth trying this first.
You could also try putting the phone in a warm place for a day before doing this, just to make sure it's completely dry.
Got the same problem on froyo, but I didn't got it wet. It looks like there's something bad with froyo, but I don't know what exactly. I think getting back to the stock firmware would help. I will try it tomorrow, because my USB socket is broken for a long bit of time, so I was flashing from SD card, but my reader broke too :/
I had the same problem with touchscreen on froyo with the same errors. I thought my kaiser was going dead, but helps me taking battery out. Now everything is ok.
Don't know if anyone else is experiencing this with their Play but as of a week or two ago the backlight started acting strange. The backlight will randomly stay off when I push the power button with the slider gamepad closed. Only way to make it come on is to pop out the slider. It seems to be random, and if I push on the slider edge slightly with my thumb with the slider closed the backlight randomly flickers, ranging from slight to severe.
The display is still working despite the backlight issues, I can open apps, and use the phone normally but the backlight flickers on and off. Makes it especially hard to use the phone in the dark.
Phone has never been dropped once.
I've replicated this problem with a variety of roms, both custom and stock. It's definitely not app related or even custom kernel related. It happens on a fresh wipe with stock rom with stock kernel. It happens on CM7 with custom kernel.
I'm curious if anybody else is experiencing this. It would tell me if it's just an isolated incident or if others are having this problem.
Sounds like a faulty connection to the backlight to me.
I had the same problem 2 days ago. Then I couldn't get my phone screen on at all!
I sent my phone back to Sony, even thought I bought it second hand. Phoned them up and talked to them. They asked what time of year I bought it so I said around August and then they gave me the address to send it to. Now I'm just waiting to see what happens next.
If your going to send your phone to Sony for repair then make sure you put the fresh firmware back on and un-root your phone as that breaks the warranty (unless they don't know about it)
Hope I helped you. If I did then click the thanks button
Sounds like a faulty ribbon cable to me. (cable that connects the screen to the rest of the phone)
You wouldn't need to drop it for that to go bad, It could just be a case of opening and closing the gamepad or lot.
Yeah good thoughts, most likely the ribbon. That really sucks because I've only had the phone for 7 months, and I've taken excellent care of it. Sounds like a major design oversight.
Mine is probably near complete failure at this point. It's taking a lot more effort to keep the screen on now. Fearing soon it won't work at all.
In hopes that this might help someone else down the line, I was able to fix my problem. Yesterday the screen pretty much quit and I had no choice but to try and solve it myself or buy a new phone.
Using this disassembly video as a visual aid I carefully pulled my phone apart: http://www.youtube.com/watch?v=-3n5ZfkqhzE
You'll need a torx T5 tool to pull out all the screws but they are cheap.
Underneath the phone and jammed into the screen ribbon was a rather thick hair just hanging out. Somehow it buried itself in there. I removed it, unplugged and replugged the screen ribbon and cleaned the dusty inside with a q-tip and reassembled it all together.
It works fine now, so hopefully this helps someone else avoid having to pony up for a new phone. For those under warranty probably best to send back but for those like me with no warranty it's worth the shot.
Verizon VS-986 here.
A couple of days ago, I went into the Camera app to take a picture and it was "stuck" on the selfie camera, and the icon to switch to the main camera was gone. I went back to the home screen and back into Camera, and fiddled with the Modes, and it finally came back. I clicked on it, and the app showed an image for a couple seconds, then froze up. I did a lot of back and forth with it, and sometimes it would show an image for a second and freeze; sometimes it went totally black and froze the app; eventually, after power cycling a few times, it was stuck on the front-facing camera for good, with no icon to swap to the back camera. Basically, at this point, the app had recognized that there WAS NO back camera and didn't even bother presenting the option anymore.
This had all the hallmarks of a hardware problem. Glitchy, intermittent outages, then the hardware simply not recognized anymore. Still, I cleared out caches and searched online and found this article: How to Fix Camera Failed Problem on LG G4 (recomhub.com/blog/how-to-fix-camera-failed-problem-on-lg-g4/), none of which did anything to help. (I'm not rooted/unlocked so I couldn't clear the cache partition like they recommended, though it clearly wouldn't have helped anyway.)
Couple other things that may or may not be relevant: it was VERY hot out (80+ degrees) when then problem started and the phone was hot as a result of it. But it kept happening after cool down.
A crazy other thing that happened was, that evening, after rebooting one last time just to be sure, half the screen turned into rainbow noise during the Verizon logo and stayed that way for several seconds, even into the lock screen. That pushed me over the edge.
I went to a Verizon store and they kindly swapped it out for me. But that was weird and I wanted to put it on the record. Also curious whether anyone else had this problem.
Not that problem, but check out this other thread I started regarding the camera causing the phone to overheat: http://forum.xda-developers.com/showthread.php?t=3142806

I've had the rainbow noise on the right half of the screen show up on boot at the Verizon screen as well. It stayed that way until the lock screen and that's when I powered the phone off, pulled the battery and let the sit for a few minutes. Haven't had the problem in the weeks since I've had the phone though.
The exact thing happened to me. My rear camera will not work at all. And the flashlight also will not work. Tried rebooting, factory resetting it, clearing cache, and took out my battery and still nothing.
I had a Verizon G4 that the rear camera stopped working on. I believe it was caused by a drop. I posted on here about it. For mine it just wouldn't focus anymore. Replacement was very easy, you only need a small Philips head screwdriver, and your fingernail, or plastic tool to remove the connector and pry the camera out which is held in by adhesive.
Replacement OEM part out of a Sprint G4 was under $14 USD on eBay.

Hello,
I have the exact same issue. Do you have a solution ? I dont want to rma anymore, screen coating than bootloop than this, this phone is a true disaster.
Only other thing any one could try is a tot lgup restore if that dont work either more than likely its a hardware failure. I had issues on my g2 with a could not connect to camera from the factory. Found out my stock rom was corrupted from lg toted and worked like new. Did it again a few moths later. Toted avain worked like new. I asume something in the camera files corrupted. Just throwin in my 2 cents.
Hello, thanks for the answer.
I fixed the issue by myself few minutes ago, i simply disconnected than reconnected the rear camera plug to the motherboard.

Jesus i didnt see that. Sorry
So my brand new original camera module arrived today, i replaced it myself and...the camera still doesn't work. Looks like it's an MB problem. I have to send this god damn phone to LG again..
Hello, here is an update about my camera. LG repair the phone by changing the motherboard and the camera module.
Hi and thank you for checking my thread
I have a problem with my G3 as described in the tittle, I did the Paper trick I saw on YouTube but sadly it didn't work
After a while I found out that placing a piece cut from Credit card under the CPU might work and I did , but one week later I had the same problem, likely I can just click sleep button and it returns to normal
After these many problems I decided to give up on it and sell it, but I need a permanent Fix so I don't get involved in Cheating
Also , does replacing motherboard will fix the issue ?
Does G4 Worth it now ? I know about bootloop problem
Probably is a bad motherboard
When my G3 finally died (digitizer went bad), I just replaced it with a used G4 for $150. That was like 6 months ago. The phone has been phenomenal. I know there is many who say that every G4 will bootloop eventually, but I really don't see how thats possible if you just browse google for the issue. Yeah, a lot of people had the problem, but if everyone did you wouldn't see the G4 still being sold at a ton of outlets, and you would see hundreds of links to the issue. I think there was a large batch of them that were bad... and they got past QC, but the vast majority of them are probably fine.

Replacing the Motherboard will fix the issue ?
Yea, i saw "1 month/year after" Reviews on youtube and no one montion the bootloop issue, people ask them in comments and they reply that the phone works normal with no issues
Thank you for replying dude appreciate it
I was skeptical at first, but by baking the motherboard in the oven did the trick for me. It has been a couple of hours now an no flickering, no black screen and no troubles. And i know i'm asking for Murphy to come and bite my as*, but as a little trick, i'd like to suggest before putting the mobo in the oven to try something: i have an old Akasa X4 cpu cooler which has metal fins which are removable. I took one of those things and cut a square a little bit smaller than the power IC to the right of the SoC and then cut another one the exact same size then stacked the two one on top of each other, making sure to not short any capacitor around the IC and then put the metal shield back, making sure to put pressure on the IC. Then preheated the oven at roughly 180 degrees celsius, then put the motherboard SoC face up into the preheated oven on three balls of aluminium foil, one at the bottom near the micro usb, and the others to balance the motherboard, like a BMW Isetta, and put the timer for 10 minutes. After these nervous 10 minutes, I took out the mobo and let it to cool at room temperature for ~30 minutes. And voila, now it works. I do hope that it is going to last, and i will be very careful with this phone, unlike the previous owner. Seriously, how can you put a freaking button (small one, from a shirt) between the SoC and the mid-frame? Crazy. And that's why i got it for ~8000 JPY (about 70 bucks).

I had a similar problem for about two months. I tried the paper thing over the camera sensor and I felt like it helped some but the problem still continued. The screen would just slowly go dark with vertical lines running through it. All apps would still work in the background while this was happening. I could boot to TWRP and this problem never happened while in TWRP which was odd. Seemed like if it was a screen issues or hardware malfunction it would happen all the time. That's when I decided to just flash back to stock. I was thinking about getting the S8 anyways so what the hell. I flashed to stock 10B and took every single OTA. Took all night but I've been running stock for over a day now and the issue has not replicated itself one time since reverting back to stock. I was on RR Nougat and Fulmics when it happened prior. Has to be a root or Rom issue?

Just wondering if your G3 is still functioning without the issue.
It really feels like a hardware issue but as you pointed out it didn't happen in TWRP... but like many, I encounter the issue when the phone gets a bit warm (>35C), so maybe TWRP and your stock android is not as hot as RR Nougat? Then again, I'm on MM when this happened...
Update: Actually the flicker n fade happened to me in TWRP while I was backing up. The temperature read about 60C.
I had bigger problems with my g3 and they started as follows
Problem 1. camera not being detected and crashing. 2. Reboot once a while which got worse over time. 3. Bluetooth sketchy and WiFi not connecting. 4. Sd card being ejected and mounted constantly. 5. Mobile data stopped working.
Solution: baked it in the oven 10min with cpu side up at 185c removed to cool 4 30min. Problems gone for the meantime.
This morning at work my D852 died with the exact same screen fades to black and would only stay on for at most like 10 seconds and would only come on again after the processor cooled enough. I came across this youtube video.
https://www.youtube.com/watch?v=UF1s4RCZAvc
Since I didn't have any copper foil tape, I substituted with Aluminum foil tape and placed the tape in the same places as detailed in the video. (copper works better than aluminum for heat dispersal)
My phone is now back to normal and hasn't shown any issues with the past 5 hours since I applied the fix.
UPDATE: My phone has worked perfectly for several days now until I turned on the GPS from Cell Tower to High Accuracy and it immediately started to die again. Once it cooled down I was able to get to the settings screen to turn off GPS and it went back to functioning like normal
How to fix
I tried the paper trick and it did not work. No need to replace the motherboard or the phone. The issue is just a bad connection between the motherboard to the LCD display.. Probably due to dirt (in my case, I found that quite a few places in my motherboard had corrosion buildup). Here is the fix...
1. Remove battery cover and Unscrew The back plastic from the base of the phone to get to the motherboard.
2. Disconnect all the connectors from the motherboard.
3. Scan the motherboard for anything unusual. (My motherboard had corrosion on several different places).
5. Clean any dirt or corrosion with lint-free cloth. (I didn't have one so I had to use a Q-tip).
*if needed, Dip the cloth in rubbing alcohol to assist in cleaning. make sure that the cloth is JUST BARELY Damp and not dripping, otherwise you will risk water-damaging the phone. If you use rubbing alcohol, make sure that you dry the spot right after you wipe it.
6. Once you have cleaned the motherboard, check the base of the phone and clean any dirt from here also.
7. Replace the motherboard, re-connect the connections, screw on the back, and put the battery cover back on.
Viola! Mine has been working like new for 4 days so far with no issues...

So a permanent fix is a new motherboard or a new screen?
Hi all,
I have a general hardware problem with my Samsung Galaxy Tab S4. Maybe someone here has an idea or tip for me.
I still used the factory software without any rooting or unlocking the bootloader. So everything original and up to date.
A few month ago the tablet began to restart in the middle of using it. At the beginning it happened seldom, but then more and more often. Also during the restart new restarts happened more and more often, so that it took several retries, until it started again. Now it is not usable anymore, because it is not running longer than a few seconds before the next restart if it happens to boot completely at all.
I was able to make a factory reset but this didn’t solve the problem.
My first theory is, that this could be a problem with the battery, that it is slowly dying and had more and more problems to hold the voltage. But the problem also exists when the power supply is connected. So I am not sure if this rules out the possibility, that this could be cause by the battery? Does somebody know how this is internally wired, if a broken battery could still have a negative effect when the power supply is connected?
Do you have other ideas/advices, what could be the problem or would could be helpful to do?
Thanks in advance for any help.
Best
The USB power input can't sink enough current to boot it or even run it without the battery acting as a reserve during peak usage spikes.
Replace the battery and go from there.
Thanks, then I will try this.

Hi Vertex, have you tried this already? I have pretty much the same problem and the battery was also my first intuition, but I don't know if buying a new one is worth it. Thanks!
Hi,
unfortunately I didn't had time to do it yet. I want to change the battery myself and for that I will need time and somebody to borrow me a hot air gun, because everything is glued together.
I will report, when I have done it but it will be at least a few weeks.
Alright, so I'll probably try it sooner, I'll update after replacing the battery. Also, if you haven't tried it yet, you might want to try just disconnecting the battery from the motherboard and connecting again after like 20s, I've read that it sometimes resolves this problem, but it didn't work for me. Fortunately removing the back lid of tab s4 is pretty easy, I used hairdryer, so with heatgun it should be even easier.
Thanks for the tips. I am currently on vacation but when I am back I will also try with a hairdryer.
Any additional tips for removing the back lid to somebody doing it the first time beyond what you can see in the youtube videos? How do you glue it back together?
Hi, sorry for the late reply.
I have eventually replaced the battery, and nothing changed unfortunately… I did a factory reset, etc. However I also had an issue that you didn't describe in your original post, which is that USB connection is not working, it only charges the battery, when connected to the PC while booted it's just not visible at all (tried with several cables, two computers, on windows and linux), when in download mode it kind of shows up, but it's not recognized and no drivers or any solution that I've found are working, so I don't know if it's still hardware problem something with the USB related parts or something in the system on lower level. Well, I'll be trying.
About the back lid. Beyond YT videos only thing that comes to my mind is patience. About the glue, you have few options and it depends a bit on how removing the cover goes. 1) glue stays in the more or less same condition as before removing the cover - that's how it went for me - in that case you can just reuse it, just by closing the cover and pressing it down for some time, it's probably not as strong as new but for me it worked just fine, especially if you use a book cover for the tablet there won't be a problem.
But if the glue came off, wrinkled a lot, or just doesn't stick anymore, 2) you can either use a special epoxide glue often with signature like T-7000 or T-800 but if you just look for a glue for smarphones you'll easily find it. Or 3) Buy a special sticker for this exact device which has a specific shape, it's pretty much the same thing as is used by manufacturer.
