Touch HD/Blackstone Backlight Auto Adjust Problem

Firstly let me say this:...... I have a phone that has had to go back once because of a weird problem - so it might be "one of those phones " (the prob WAS fixed by a new board from HTC but thats another story !)
Here's the prob. Today when I was typing a text the back light kept adjusting up and down. This has NOT happened before So I did some tests:
1) Its to do with the autoadjust feature (not a prob when its OFF)
2) All is OK UNTIL you start to type this is how I spotted it typing a text. The backlight was going up and down - I thought my eyes were going!!!
ATTEMPTED RESOLUTION:
Fristly I did a soft reset......(prob still the same)
I down loaded LUMOS, which shows actual numbers for the light sensor,
Here's what I found......
It moves up and down a bit then settles, in a dark area its on say 3 or 0 but when I type on the screen it goes up and down like a yoyo ! ie 3,79,120,3,0 if I stop typing it settles on 3 or 0. AND THAT IN A NUT SHELL IS I "THINK" THE PROB !
"The light sensor seems to be affected by typing."
I never noticed this before so this may be a fault.
LUMOS seems to cope slightly better than win software with this and I can get around this by turning the sensor off, but if its faulty BACK it GOES....(AGAIN)
The last prob did my head in. I love this phone but I'm not sure if I got a touchy one !(pardon the pun)!
ANY HELP/THOUGHTS VERY GRATEFULLY ACCEPTED

Further update - CAUSE !
I have found out the cause !
It happens when screen taps (sound) is turned on and is FINEwhen it is off. I only tuned this on last week !
SO what they heck this is some software bug perhaps - any thoughts ?
Thanks so much !

First my touch hd died suddenly two months before one year is over. So I sent in for repair and paid $20 for some sort of fee on the top of shipping in. When I get it back, I thought everything is doing fine. Then suddenly the screen started acting weir. It turns on sometimes but sometimes it won't. I tried master reset. I tried to contact Htc. And I even try to hit it since I was pretty upset getting this lemon.
I happen to have to travel to Taiwan and I took it to a cell phone store hoping they can fix it since it is a Taiwan phone. I got it back today and they said it will cost $170 to fix. And they said that I got liquid in. I have never let it get close to any water or liquid. Obviously they said the sensor was activated. (I don't even know there is a sensor for water).
Anyway, my phone now can call in but screen turns on when it likes to. While I am now playing with it. I turn all the auto backlight off, including with battery or power connected. And I also turn off the auto backlight sensor. Somehow for almost two hours, I can turn on anytime I want to and off any time. I do not how long it will last. If this is the problem, that means the software of auto backlight off has bugs. I hope this helps those who are like me lost some sleep over this HTC nightmare. I do not expect it is fixed at this point. May be I am just lucky that it stays controllable for the past two hours. Good luch y'all.

unresponsive touchscreen?

My nexus 7 currently has an unresponsive touchscreen. Almost none of my touches are working now and yesterday the tablet was working just fine but some of the touches were not working. Now almost all the touches arent working, did the hardware just fail on me?

Here is what I posted yesterday on another thread, but short answer is that yes it's most probably hardware fault (I don't have picture at work, so can't attach it here).
I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport . Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.
As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.
I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.
EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.

Screen Flickering on edges

Hello,
So I got my Nexus 4 and it was all good for i think 40 whole hours, never left my desk and then i noticed a strange flickering of the screen, it was on all screen and everywhere, i put it to sleep still there upon awake. I restarted the phone and it was still there but less, and then i pushed soft on the edges and it went away..
Sucks, It took me many months to get this new phone stuff put behind me and now I don't know what I should do send this to google and get a refund ? What a gong show getting this thing, and then wait for months for a replacement ?

[Q] TV-LIKE(snowy) screen , any help with that? It must be a design defect

Hi all dear members. Since the first day i bought this phone i've been seeing lots of screen issues about it but i never thought i would have one. It's proved me wrong.
So here's my problem, my device has developed halo all around it when the bg color gets grey. Most of the time , it's not obvious. I can live with that. Recently, my screen starts to show me some tv-like stripes every now and then, it doesn't last long. after one second or two, it disappera and then it'll show from time to time.
I'm afraid it's just the start. It's similar to most of the issue ppl claim as screen flikering or screen jittering or shaking screen, it's a bit different though.
Has anyone encountered the same issue. More importantly, has anyone found any solutions yet? I searched google and failed to find answers. And i looked into it on Baidu,a chinese search engine, where i found some answers that claims it's not the screen issue ,instead , it's just the ribbon cable is lose. And anyone who replace a new screen for that is stupid.I'm just not sure about this.
My phone was bought on the internet and shipped to China, thus, I don't have warranty to rely on. And my phone is only 10 months old. I never dropped it and i have kept it well.(LG logo on the rear back still falls off), I just don't get why LG made this so vulnerable.
Even though i have ordered the nexus 6, my g2 running CM12 is still crazily fast and I don't want to give up on it. I'm so happy about my d802 except for all issues about the screen.
Any help would be aprreciated. Thanks again. Hi all dear members. Since the first day i bought this phone i've been seeing lots of screen issues about it but i never thought i would have one. It's proved me wrong.

Hi, I also have a problem with the screen on my lg g2, appeared to me that the white line disappears and comes back, when I do print screen and transfer the image on the computer that line is not visible, and that line is not always the same intenziteta.Try to do print screen and set an image or we send the mail to compare the problem

i'm so pissed about the screen, yes, my gnex bought 3 years ago looks yellow and ****ty. but other than that, totally fine, but for g2, ive read so many complaints about it. Guess no one has figured it out. Maybe I will open my phone and try to figure out when the screen completely goes crazy. During I type, it has happed for 4 times . so very annoying.

I think you should try to put in some rom, I hope it's a software problem, I found the solution for my phone cloudy g3:good:

i flash different cm12 nightlies. i don't think its a software related issue. I'm not the only one with this issue. Yesterday I opened this phone ,well with my fingernails. And coz I didn't have the right screwdriver, I wasn't able to open that black cover at the button down bellow the battery, but I cleared the places around the USB port and there's a black tape glued near the camera , I pressed it and I put the phone together and guess what, the problem was gone for one day, and I will continue to keep an eye on it.

Moto X Pure exactly half display not working

I've a Moto X Pure (XT1575) which is rooted and running 6.0.1. Not exactly stock as I flashed CYMD before, had problems and returned to near stock. Two days ago I flashed LineageOS and when I turned my phone on the screen was cut perfectly in half with the right half all static. I restored the phone to a backup I'd made before the flash and the screen was fixed, while in bootloader and that the screen was normal. Then yesterday I take the phone out of my pocket and the problem is back, this time when I'm in bootloader/recovery the problem persists. Did a restore again to no avail. The touch still works on the right half of the screen just cant see anything. I've seen a few threads like this and they all say it's hardware related, which it probably is, but why would it happen straight after flashing Lineage and without dropping it since? I also had a new screen installed a few months back by a third party, not Motorola.
I've attached a picture of what it looks like.

I just logged in to post in the other thread that my replacement screen only lasted a week and I saw this.
This is my third screen.
The first replacement was because I dropped my 4 hour old phone, the second was replaced because the left side of the screen went all staticy just like your picture, and now my third screen crapped out all staticy on the right hand side after only 3 days of use. At $50+ a pop for new screens I think its time for a new phone.
They are real easy to replace though if you choose to go that route.

My old Nokia Lumia 920 had this problem too, after I upgraded it to Windows 10, but the whole screen looks like what happened to your half screen. The problem could be caught by the Lineage OS, maybe it's the kernel's problem I think...

Yea this will be my second replacement screen. Replaced the first myself but don't have the proper heat gun/glue tape myself so may pay to get it done this time. Bringing the cost up to near $100 a screen. Time for a new screen is right, just waiting to see what comes out in the next few months
