HDX 7" weird touchscreen issue. - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

Hi Everyone
So I've been having issues with the touchscreen for Kindle fire HDX 7" tablet. I have spoken to Amazon customer service which was no help and the only help they offered was for me to buy a new Kindle which is unacceptable in my opinion.
When I first turn on my tablet everything is working fine with no issues, but after some light usage and maybe some internet browsing it starts to lock up. It almost seems like there's some memory leak issue where the RAM fills up too fast causing the device to become unresponsive. Some parts of the screen becomes unresponsive while other parts of the screen work ok especially when using the keyboard. The tablet seems to be completely responsive again if I press the power button where it takes me back to the homepage but only for like 2 minutes and then starts to do the same thing again. One thing to note is it's not always the same area of the screen that becomes unresponsive.
I have tried doing a factory reset, hard reboot, and even used a custom ROM (CM 11 using Safestrap v4). I am still getting the same issue so now I believe it's some sort of hardware issue but not sure which. I would like to see if I can fix this as I did spent over 240 dollars on this device. Could it be the screen display and digitizer causing this issue or something else? There are no cracks in the screen and I do not believe it was ever dropped. If anyone can shed any light on what could be the problem that would be fantastic.
-Thanks
Matthew

[Q] Severe screen flicker

I bought a new Google IO Galaxy 10.1 about a month ago from someone who attended the conference. I haven't had any major problems with it until tonight. For some reason, the screen flickers so severely that the tab is unusable. I thought maybe there was an app that wasn't compatible with HC3.1, so I wiped it clean in fastboot and reflashed everything to stock.
Unfortunately the screen flicker remains, and turning the screen off and on provides me with only a few seconds to see what I'm doing. I will post a picture after my 8th post.
Anyone have similar problems? Any idea what could have caused it? Since I bought it in a private sale, I don't think I can send it in.
Update:
The screen flicker was completely gone this morning after letting the tablet sit overnight. Unfortunately, upon rebooting, the flickering has returned in full force.
Update:
The flicker, which was more like trying to watch a scrambled t.v. channel, has disapeared on it's own. Very strange, maybe the gpu was overheating due to overclocking.
Problem still exists, unrooting and sending it in.
Thanks for all the input... pfft.
I just experienced the exact same issue for the first time this morning. The entire screens flickers and becomes scrambled which renders the touchscreen useless.
My tablet is in factory form with no rooting or overclocking so I find this puzzling....

Touchscreen Unresponsiveness?

So I made the jump from Android (Nexus One) to the Radar and I really like it so far!
I do, however, have an issue with the phone that I am wondering if anyone else has noticed.
I have noticed that sometimes when I go to touch a tile(or other UI object)...if I quickly touch it, it seems that the screen doesn't always detect my touch. Sometimes I'll even hit it a couple of times before it responds.
The behavior is inconsistent though. After it smartens up and responds to my touch, then it seems to detect it fine. It's squirrelly and a little disconcerting.
I also think that the region of the screen might have something to do with it. The tile 2nd from the top on the home screen ("messaging" in my case) seems particularly susceptible to this problem.
Has anyone else noticed this? I'm a little paranoid because I bought this phone "new" from someone on CL and when I took it home I realized it was a refurbished model.
I had this problem when I had my 7 Pro. After a while it got worse, as I had to put the phone on standby and then turn it on again to be able to use the screen. I sent it in to HTC for repair, and they swapped the entire front panel with a new one.
Im having the same problem with my sprint arrive I think the problem is related to what is in this thread:

but I still cant seem to get it to work

[Q] Screen flicker/dims/blacks out issue

Any help much appreciated....I have an issue with my screen flickering, dimming very faint and going black when i touch my screen. sometimes my screen will go black for long periods of time and phone is practically useless. This is not an issue of just a slight flicker on light colored screens that I have read other people describe. The screen does not always do this but is definitely getting more frequent. The flickering/dimming happens when I touch screen and especially when I touch it with more pressure. It also seems to be more sensitive on the bottom half of the screen.
I consider myself as the "scientific type" and have been testing many different scenarios trying to find a rhyme or reason to this happening. The only thing I have found is that if I keep my phone out of my pocket the problem seem to not happen. Then I can put my phone in my pocket for as little as 5 minutes and my screen could be messed up for hours. Everything else about phone seems to work great.
At first I was thinking this was a software issue but now I am leaning towards hardware? I am rooted, unlocked with s-on and cannot send back for warranty. I was running mean Rom for many versions and have also gone back to stock rom and stock kernel and experience same problem. Many reboots and clean installs too. I have also taken phone apart and reconnected all ribbon cables hoping there was a bad connection.
My Evo lte is only 4 months old and has never been dropped nor has it ever been wet. There are no scratches on screen and has been in otter box since the phone was brand new. I am running out of ideas and am I dire need for advice.
Thanks,
Mike

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new

Problem with touch screen or software bug?

I bought a Mate 20 Pro on preorder and noticed within a few days a seemingly non-responsive part of the screen that was an intermittent issue.
Basically every now and again (often enough it’s annoying but not every time) after I unlock the display I am unable to select any app icons in the lower half of the touchscreen. The top half is fine - the home buttons are fine but everywhere from the middle down is non responsive.
I assumed a hardware fault so amazon replaced it for me - and the new device is exactly the same!
Am I just super unlucky and have managed to get two faulty devices a month apart from Amazon or is something else causing the issue?
Thanks.
Think you've just been unlucky,nothing like that on mine
Fine here too. I assume you tested this as soon as you got the phone before installing any app / custom launcher?
Have you tried running smart diagnostic tests manual mode in hicare, there's a touchscreen display test.
Sent from my HUAWEI LYA-L09 using XDA Labs
I only noticed it in use after I used a custom launcher however I tried multiple launchers and saw the same behaviour.
I just did the HiCare test and it says normal. I did hard reset it the other day and it hasn’t happened since so I will see if anything else happens. I can’t say I am thrilled by the thought of another swap from amazon if it does happen. That’s super bad luck.
Hi how did it go after the hard reset?
I got the same issue myself but instead of being the lower half, my entire screen does not respond to touch. I've done a hard reset my self and i do run the stock launcher. Even though my screen still doesn't respond to touch now and then after unlocking the screen or receiving a phone call.
Touchscreen issue
Yup I get it annoyingly so as well! Often takes a "double tap". Pain in the ace!
