So I've got a relatively cheap used sensation off ebay. It was announced defective and it was stated that part of the screen is dead. So I thought there were some dead pixels which didn't seem much of an issue for me. However, there are no dead pixels, the screen looks fine. However, it is very unresponsive. I have trouble pulling the ring to unlock the screen, selecting icons, typing, ect. There is also one part of the screen (one whole row) where the screen is completely unresponsive (doesn't react at all when touched).
Tried the SGS screen booster, tried cleaning the metal contacts on the battery side of the phone... nothing worked. The phone still has it's warranty seal, so it doesn't seem to have been opened..
Any suggestions other rhan faulty digitizer?
Thanks for your help
Sounds exactly like a faulty digitiser, which is costly to repair unfortunately, although it it surprisingly hard to break them, recently smashed the glass on mine, and the touch still worked perfectly!
I just asked the seller what made the touchscreen to stop responding. He said the phone fell off, hit the ground and afterwards the display wasn't working properly. Maybe there is some other way to fix this? The digitizer itself is not broken.. maybe there is something that got displaced.. or maybe there is a faulty connection somewhere on the pcb... do you have any suggestions? Thanks!
just noticed that if I squeeze the phone top to bottom (i.e. grab it with the thumb onto the unlocking latch for the back cover and the middle finger on top of the phone, just above the speaker) it opens 'messages'.. So maybe there is some bad connection on the pcb? Or should this definitely point to a faulty digitizer?

I have an Lg G2. Works great.
Yesterday I noticed some weird behavior. The screen was finicky and hard to use. The screen is cracked on the two left corners of the phone but the display area is perfect. The picture looks perfect...
I decided to open up an app where I could draw and it turns out I can't get any input on a perfect row about an inch or so from the top of the screen, and about half an inch across, all the way from one side to another. I can color in the whole screen but it's perfectly blank on that one row.
I did some research and figured it might be some loose connector with the digitizer.
Is this possibly an easy fix?
I have warranty but no insurance
Thanks!!!
Bump
Check the connectors
You cant really cause anymore damage by just checking the connectors going to do that when i get home tonight, I'll tell you if it works
Woke up this morning, check texts on my G which works fine, pocket it (front left pocket, screen facing my leg, nothing else in there, loose fitting pants), go to work, check it about an hour later, can't undo my screen lock, touch screen is acting all wonky, I'm not even touching it and I keep seeing wrong input over and over... so I turn it off and back on, but I still can't use the touch controls on the left part of the screen (the left and center row of the lock screen doesn't respond, the right most one does, and the very bottom emergency calls does).
So I carefully inspect my phone, there is not a single mark on the screen, bezel, back-plate... the phone is in pristine condition, I take good care of my electronics (or so I thought). I start checking the screen against a light at various angles and on the bottom, slightly under the lock screen dots, I see a very thin line under the glass but above the screen, starting at one edge and going about halfway across. Like the touch sensor is partly cracked, but nothing else is?
So I was wondering, does this count as physical damage? I don't see how it could. As I said, the phone is pristine and I can't imagine how I could have damaged the touch sensor without leaving a mark on the glass, bezel or screen.
But I'm still worried that Futuretel, which is where the Motorola people are telling me to send the phone will call it physical damage and have me fork over 150$ for a repair I could do myself for 50~60.
And I would do it, had I actually broken my phone... But I didn't, so I don't feel I should pay for this at all.
Hi all
My moto Maxx has gone through a lot, but the strangest problem yet started yesterday.
As you can see on the attached video, half of the screen is constantly scrolling. This happens in fastboot and recovery mode as well, so I'm pretty sure it's a hardware problem.
The digitizer still works perfectly, and registers touch where the icon or button should be positioned on the screen. The moving screen also does show everything correctly, just in this crazy scrolling way.
I'm not very hopeful in fixing it, but was wondering if anyone has ever seen this, and if you guys think this is a broken display(and any way to test this?) or a broken GPU. If it is in fact the display, I might consider replacing it.
Some background on all the terrible things I did to this phone:
- Dropped it and cracked screen in September.
- Replaced the glass myself, slightly burned display when removing glass without any consequences (just a tiny mark on the top right, the side that actually still works).
- Dropped again, broke glass again, never bothered to fix it, some small pieces are missing so dust, sweat,.. could've gotten int.
Video:
Most likely the display being broken.
Even when my tempered glass protector is missing chunks the screen starts to funk up. Only worse being the real screen especially the digitizer.
You might be right pjd, or at least screen related.
I opened it up yesterday evening, and I think it might be the cable connecting the screen. Depending on how I positioned the screen and thus the angle at which the cable was bent, it was fixed, the same, or just completely black.
The only thing I have to try to find out now is if it's the kabel, or the connector on the motherboard. Any suggestions on how I could test that are welcome!
Hi guys,
I have a Dasaita PX5 unit with Android 8.0 and 4 GB RAM.
I've bought it a few months ago and it was working fine until today the screen just went crazy.
The screen will start touching itself all over and enabling settings, or quitting my GPS software, or activating apps, or flipping through different screens etc.
I've tried to update the system software, update the MCU, and even a factory reset. The crazy screen issue still persist.
Any idea how and why my screen went crazy and how do I resolve it?
Thanks
Here is a short sample of what I meant by going crazy:

I know exactly why and have had the same problem. There is a ribbon cable that comes out of the screen between the glass and LCD for the digitizer, its damaged the screens are so cheaply made the glass is still somewhat sharp and the cable kinks and breaks. . I actually just came on here to post if anyone knew where I could get a replacement besides Aliexpress.....
You should try reconnecting the ribbon cable, else just get yourself a screen replacement from where you bought the headunit.
I had similar issue where bottom part of the touch screen no longer register touches and as time goes by, the whole screen is completely "untouchable".
The root cause is that the ribbon between the unit and the screen panel connect to the mainboard is rubbing against the unit casing's sharp edges causes permanent damage. Fortunately, it is still under warranty and i have got a replacement panel, smoothed the casing edges and place some duct tape before replacing the panel.

I just tried it and it got worst. :S
Someone with the answer?
In the last two months or so I cracked my screen with the shatter/cracking starting in the upper right-hand corner of the phone. I still have not found a suitable solution for fixing the screen, I was hoping to get a solution to an issue this seems to have created where the display will not turn on.
Simply put, the screen no longer turns on unless initiated by the software with activities like "Hey Google", receiving a text/call, or plugging/unplugging the phone. The majority of the time I cannot get the phone to turn on with normal methods such as media gestures (double tap), any buttons (volume/power), fingerprint sensor are all unable to turn on the screen. Strangely, many times I will receive haptic feedback that senses the physical method I am using but the screen still fails to turn on. Squeezing the phone also doesn't work but is not desired any more as a concern for making the cracking worse.
It's a US phone, rooted, 1.30.617.2 with Magisk and Xposed. I have tried a variety of possible methods with no success including gravitybox hardware tweaks, Cleanslate kernel options, and a variety of stock options that were all unsuccessful.
My best guess is that the cracking on the screen starts in the upper right-hand corner where the proximity sensor is. It is completely shattered there and I have a clear screen protector as well. Is it possible that the proximity sensor is causing this? If so, any suggestions to disable it somehow. If not, do you think it is a damaged product or something else?
With the difficulty of getting and swapping the cracked screen, I am hoping someone can help. THANK YOU!!!
I recently just swapped the screen on mine and it was a bit of a challenge but not too difficult that I wouldn't do it again, for someone else. LOL. Anyway it might be possible to disconnect the prox sensor simply by removing the back cover and a few screws at the top of the device. Not 100 percent sure it will still work or what reaction you might get by disconnecting it, but if you're not going to replace the screen it could be worth a try. I found a couple of sellers on Ebay shortly after Christmas and considering what the phone cost, to me it was worth it to replace the screen but maybe not twice, thus my little joke earlier. There are tare down videos on YouTube if you need that kind of help.
Just checking in to see how things were going and if you tried anything? When my screen cracked I put a tempered glass screen protector on it to prevent any further damage and to prevent finger damage from the small shards that develop in the cracks. I had another phone I used tape on to pull the shards out and it ended up ruining the digitizer so this time I just covered everything up and moved on best I could. Looks like the seller I got my replacement still has some if you're thinking about replacing yours. It says New Condition but mine had definitely come from some device but whom ever removed it did an excellent job because it arrived very clean and ready to install. Getting the old screen off was the hardest part, well and finding the right adhesive to glue it back on. I wasn't able to find the G7000 glue but used F6000 which I found easily. I haven't had any issues with it since. If you want to know more about how I did it check out my thread in this forum. Here's the link to the seller.
