[Q] Galaxy mega touch screen not working - AT&T Samsung Galaxy Note II

I received a phone that the lower part of the Digi was non responsive. So i ordered a new LCD/Digi part and installed it. After first installing the part the Digi was not functional at all on the new screen. So I figured that the part was just dysfunctional and i would send it back.
But I was curious and did some other tests. I put the old screen back on and it partially worked. Then without powering down the note 2 i switched the screens. Now the part i ordered worked perfectly! The home buttons even started working(they didn't work with the other screen).
So i think i have solved the problem, WRONG, i then took the battery out to insert sim car and finish closing up the device. When i put the battery back in to restart the old screen was back to malfunctioning. Also the home buttons stopped working.
Is this an internal problem or is it just a bad LCD/Digi?
Thanks

I thought so too. But then why does the other screen partially work? And if it is a RAM problem how would i go about fixing this issue?

Wierdest thing happened to my 8525 please help!!!

ok so i searched on the sites for a fading to a white screen problem but it looks like its related to the dpad... my phone was really low on battery last night it kept beeping continuously... so by the time i got to plug it in the screen started to fade to white... now the screen has vslight vertical lines and every time i shut off the phone with the power button and turn it on it comes normal but as soon as u touch the screen it fades to white!!! was this caused by the low battery. i fully charged it but still have the same prob. i tried clearing my storage and that didn't help..what do i do?
white screen
you will need to replace the board for the dpad.
ok thanks. is this the same issue that others are having as well? the wierd thing is half the time it works the other half it doesnt...
I had a similar problem. I had pressed the power button to check the time and screen was white! SR rebooted and after the first splash screen the screen faded to white. I finally founded a product called Pocket Controller http://www.soti.net/ (trial ver works fine) that allowed me to see my phone on my computer. I was then able to backup my data to the storage card. I reflashed the phone and it’s worked fine afterwards.
yeah man thats what happened to me exactly... im reflashing the official wm6 rom now... ill post what happens... thanks

damn it didnt work with me my screen still goes in and out when it chooses to. and it is my dpad b/c it stops working when the screen is gonna go..
Hi,
Try tightening the screw behind the red hang up button on the dpad. There is a component behind there which causes this problem. If tightening doesn't work try loosening. It's all to do with the pressure on the chip. Very odd problem.
Also try squeezing the bottom right hand corner of the phone and SR.
Bonkers solution for a bonkers problem but it certainly fixed one of mine.
Good luck!
yes, the screw tightening/unloosing thing works for me. same thing happened when i dropped my unit. i even completely dismantled it (managed to fix the microsd card spring). something loose with the connections.
niec guys thanks... i will try the tightening and loosening the screw... i tried holding down the bottom right and SR didn't work but thanks anway... i guess i have to buy a screw driver to open this thing up... god i remember when i had to take apart my mpx 220 im getting flashbacks!!!
Had exactly the same problem but mine was due to an phone shop employee dropping it. It would do exactly the same as yours. Sometimes it would work fine and once when I reflashed it the problem went away for a few days but if came back.
I used to control it using Soti pocket controller but them migrated to Net Support as that allowed me to control over wifi. In the end had to get it replaced.

[Q] Touch Screen Problem

Recently I began to notice a problem with my phone. Whenever I have the keyboard slid out the touch screen is almost non-responsive. So over the past few days I've tried observing what the exact problem is and I think it could be the cable/ribbon that connects the touch screen to the keyboard. I'll have to tilt the screen back and forth before it will actually recognize me touching it. And I've noticed when I rub that ribbon it seems to work. There's also a crease in the ribbon where it folds on it when you close it. I believe this is the problem but I'm not sure and I want any advice/tips I can get. If it is the cable can you order a new one and replace it yourself?
Thanks in advance
Any ideas anyone? I cant get it to half work so I can text and stuff but I have to press it hard and it still wont work at times so something somewhere or another is wrong.

Flash the stock ROM and SPL, and do a warranty exchange. This isn't a device you want to open up unless you really know what you're doing and are certain of the issue. If you really want to give it a go, then just buy a non-functioning unit from eBay to use for parts. They can normally be had for less than $40.
Wow, I cant believe that I finally found someone with the same problem as I have.
At first I thought that it was a software issue and I reloaded the software on my device.
The screen responds to presses with the keyboard in, but extended it doesnt respond and only the external keyboard works.
So to type a nice long sms I would have to start it on my display, flick out the keyboard to carry on and then flick it back in before I could press send or anything.
How frustrating.
But I did a test now and flicking the keyboard out and then slowly slowly pushing it back in I can get to a stage where both the external keyboard and screen responds at the same time again.
Definitely a ribbon problem or something.
Only had this phone for a few months now and if it already doing this then I am not feeling too obtimistic about its future.
Well, time to take it in for a warranty repair. I wonder how much greaf I am in for now.
Time to pull out my awesome trusty Artemis out the cuboard.

I had a friend that had this problem with his TP2 which I've successfully repaired. First thing if you want to do it yourself, go to youtube and look for the Rhodium disassembly video (this will help you a lot). It is not difficult to change any parts in the phone provided that you proceed with caution and take the necessary precautions.
If you are afraid or have never opened up a phone to fix parts, then I would suggest to send it to HTC - this would be devastating if you managed to break up the motherboard by mistake or any other parts in the process of fixing the flex cable.
Tripp --
Did you ever find resolution to your problem? Recently my phone started having the same problem, which I originally thought was related to messing up the calibration file when I put loaded xdandroid GBX0A.
However, it sounds like my problem is pretty similar to yours -- touchscreen works fine when the keyboard is closed, but when it is open it only registers on the bottom of the screen -- which is actually useful in some sense because I can still hit the soft keys in the messaging app and such, but not so useful if you want to scroll using the touch screen. If I play around with the z-hinge a bit, sometimes it starts working -- which sounds like the same thing that you described.
Sorry, I just seen your post but I never fixed mine as I went ahead and bought another phone (Evo) but I did research the problem quite extensively and the problem I believe lies in the ribbon that connects the two halves of the phone. If I remember correctly the motherboard is in the side with the keyboard and that's why when it's slide out, the touch screen won't respond correctly. You can find the part online and replace it yourself. I've taken mine apart and it's not that hard but as said, you need the right tools and to be very careful.
Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

[Q] home button and lower left screen no longer works

I am running miui 12.11.1, stock kernel. My droid incredible as the AMOLED screen. My home button and the lower left part of the screen no longer respond to touch input. I have to rotate the screen to use parts of my screen now or I can't type in the "a" on the keyboards, or pull down the menu in landscape mode. I've wiped cache, and full wipe, but it has made no difference. I also cannot mount the internal sd card but that is a known issue with this rom I believe.
I've also tried going to a completely different rom CM 6.1 stable. but I have the same issue.
Ideas or assistance would be appreciated.
this sounds like a hardware issue and is most likely unrelated to ROM/kernel/recovery
Sounds like the digitizer screen. Same thing happened to me. Look on Ebay for a new one.
this happens with certian Dinc's. i bought a new screen to fix my home button issue because they are linked, i ended finding out it was a loose cable but according to HTC its a rare problem and was isolated to a few phones
eh. . that is ok. If it is a hardware issue than I'm just unluckly. I guess I just need to remember to rotate the screen left instead of right. Is there an easy way to map the home button to the search hard button?
I guess if it is really annoying I'll sell it to one of the devs here who could put it to good use.
Doubt its a hardware issue so test it before listening to anyone on here. I have miui as well and I have the same problem then I did a nand and flashed a new rom and it worked but I restored and the nand and the problem was back. I thought it was kernel but I flashed different ones but that isn't it...i flashed the zip for data throttling instead of editing it myself but I doubt that is the prob...so I have no cle right now I was just going to give up because now I don't even get any calls so make sure you test to rule out a hardware issue because I doubt it is bc I have the same issue and they keep getting worse until I flash a new rom. I'll try to figure it out. Ley me know on recent changes you made so that I can have some help trying to figure it out.
Well, Like I said, I wiped, factory, reset and flashed a completely different rom (went from MIUI to CM Stable) and one side of the screen was unresponsive. I turned off the phone to put in a battery and now I have all my buttons and everything seems to be working again.

I've heard of issues with extended batteries where the pressure distorts the screen so it doesn't work...
Could that've been the case?
I doubt it was the battery, I had the original battery in there when it was not working and I'm using the extended battery now and it is working, both batteries have identical physical dimensions. It may very well be a hardware issue, I noticed that when I was having problems, I could not mount my sdcard on my pc. The cable was plugged in, the phone asked if I wanted to sync with the PC but it never showed up in windows. I did it just now (running CM6) and it works. The usb cable/port is underneath the home button so maybe that port is just fragile and causing issues? I never liked the location of that port, it should be on top of the phone or underneath, away from screen as much as possible.

HTC One X Screen won't turn on, touchscreen still work???

I have been using the HOX for over 2 months now but this morning my phone display suddenly doesn't turn on even the backlight key still on and touchscreen still work ( when I sweep my finger up the unlock sound still play, and I can even adjust the volume of the phone, etc... ) I have no ideas if this is a software or hardware problem and how to solve it, I'm still on Stock Rom, Stock Kernel,... Please help me
try to reboot pressing power button for 10 seconds, if it'll not work, it can be hardware problem, as i understood you haven't unlocked it, so you can send it to htc and they will repair it, or if you can, you can change it by yourself,
have you tried starting in bootloader and factory resetting?

Yeah I tried to reset the phone, ai first it worked. But when I turn the screen off and doesn't use it for a few minutes, the problem is back again, It's really odd, I have heard about lots of HOX Screen problem but I haven't seen this one before
So the screen works in bootloader?

Sometimes it does, sometimes it doesn't. Really weird, it feels like the phone has woke up but the display still "think" that it still in standby mode
Hardware fault for sure.
Same Problem
Hey, ive been using my international HTC One X for about two months too now and there have been no problems. ever since the update to 4.0.3 ive been facing exactly the same problem. The screen does not turn on a lot of the time but the touch is active. Have you found any solution to it?
It would be great if you could help me out.
Thanks

I have the same problem now. Using it completely stock, the screen doesn't turn on. Well.... Except for the times I visit the Vodafone shop to get it fixed....
Their first reaction was a defect in the screen, so they ordered a new one. I brought it yesterday again and it is now in for repair.
I don't know if this will solve the problem. How did they fix yours?

hey guys
I had this problem a month ago, i know its frustrating.
anyway the only solution is factory rest from boot loader and flash RUU (worked for me)
the first time i had it, i did a factory reset, all my pics music were gone, phone went back to normal( stock, locked)
after a day the problem appeared again, second rest.
flashed RUU and the problem is gone. thanks god i have been using my HOX about a month science that problem and every thing is working great.
im sure its a software issue and I recommend every one to back up their files(pics,music)
just flash RUU and good luck
Lol, exactly the issue I had recently had with mine. Sent it backto htc, let's see what they would do about it.

My colleque has the same issue with his One X.
It started with suddenly everything on his screen looking "zoomed in", so everything double size, looking ugly as a mofo, and not usable. After locking the sceen and unlocking again, it was fine.
Monday suddenly also screen didn't want to turn on anymore. Did the hard reboot for him, and it worked again... Untill he locked his screen and wanted to unlock, same issue.
Also, that time when doing the hard reboot, screen didn't turn on at all. Did another one, and worked again.
He's now sent it in for repair, this definately sounds like ahrdware issue, even full reset through bootloader didn't help.

Yup, exactly the same problem I'm having, I sent it to HTC, they said they fixed it by replacing the motherboard, but now it is happening again, I will have to send to HTC again.
This just happened to my phone... Has anyone else solved it? Is reset and flashing RUU the solution?

I have the same problem right now.
It started last week when I was using Flipboard and suddenly everything started zooming in and stuff (same as mhulsegge above). It was resolved by locking my screen and unlocking it.
Last night, i've been getting the black screen when I try to unlock my phone. The touchscreen still works but the screen is just blank. It turns on if I keep locking and unlocking, but it's getting annoying.
My phone is an international One X (duh) bought in Hong Kong and I'm currently living in Canada so it would not be possible to send it back for repairs. Plus my phone is rooted and I am currently using the latest MIUI ROM (2.9.21). I have been using an app called "Sleep" which tracks your sleeping patterns. It requires you to place your screen face down on your bed when you sleep and the accelerometer will track your sleeping patterns and wake you up at the most optimal time. I assume that for the accelerometer to work the screen has to be on, so I am wondering if this can be a screen malfunction (overheat or overuse) problem since the screen has been on for so long (every night when i sleep for around a month).
Since sending it back is out of the question for me because of where I am living right now and I have voided my warranty, I am downloading other ROMs as we speak and seeing if it is a problem with my ROM. I will keep you guys posted.
-edit- I have tried factory reset and reinstalling my ROM (with a full wipe). Still doesn't work.
It´s probably not your rom since I use CM10 hand have the same problem and others have even been running stock and had this problem. The only one who seems to have solved this (at least in this thread) flashed RUU, so guess I´ll go try that now...
Would be great to hear if anyone else has solved it, and how!
edit: This has to be a hardware problem, if I push on the screen it starts working! Its like something is loose, and when i press on the screen it gets connected again.

Good tip, but I tried a gentle two-fingered push (zoom pinch) and the backlight turned itself on with very little pressure, certainly not enough to flex the screen. I believe that it is a state issue related to zoom, but will try again and report if the issue returns.
Screen black after replacement lcd display unit
Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
OneX has too much issue with Screen . WTF with HTC?

Xperia z1 compact Touchscreen falsely registers input

Hi,
Had my phone a couple of years, no problems, but recently cracked the screen.
Bought three replacement screens and fitted them in phone:
* 1st one touchscreen digitiser worked perfectly all the time but LCD was broken (had lines/artifacts on it) - sent it back.
* 2nd one, same supplier as first, LCD worked, but digitiser works intermittently - it always works immediately after phone reboot, but after the screen locks for the first time, it then has a problem where it registers an input when I'm not giving any, so the screen goes haywire and I can't even enter my pin or restart phone (Have to use red button in sim card bay). Occasionally and randomly when I try it, it sometimes works so I can enter my pin, and then use the phone until the next time the screen locks....but basically phone is rendered unusable, because this is totally random. Sent this one back too.
* 3rd one bought from a different supplier - AFAIK this one is a genuine Sony part (it at least has the Sony logo on it), but have the same digitiser problem as the second. Time has passed to send this back.
Due to the above description I am sure it is not a problem with the phone (1st one digitser worked perfectly & original cracked screen digitser worked for half the screen where it wasn't cracked). I'm also sure it's a software issue, since it works everytime following a phone reset but before the screen is locked. Behaviour seems to be the same at different temperatures. Also inspected the flex connector and ribbon components under microscope at work, and saw no problems.
One think I noticed is that all 3 screens I bought have no insualting backing on the back of the LCD, so the metal back touches the metal shield below - I did not see any screens to buy with the insulating backing - I wondered if this could be affecting the EMC behaviour of the screen (some capacitivie coupling with the digitiser or some type of grounding issue) - but then why would the digitiser of 1st screen work ok, and work for >1hour following a reset but then not after a screen lock?
Tried turning glove mode on/off - no difference in behaviour. Tried using screen while it is not fitted in phone housing (not touching metal shield), same behaviour.
I saw a couple of threads from a while back, but don't know if they are up to date, or if a solution to this problem is now known:
https://forum.xda-developers.com/showthread.php?t=2691849
This one gives a solution, but then says at the top of the thread DON'T TRY THIS FIX, IT IS A HARDWARE ISSUE NOT SOFTWARE.....so I'm worried to try it.
https://forum.xda-developers.com/showthread.php?t=2662457
This one is to adjust the touchscreen sensitivity, but even though I have root access, I get an error message relating to the mount commandwhen trying to copy the edited idc file back to the system\usr\idc directory, "operation not permitted'.
Does anyone know a reliable fix that works? Or how I can get write access to idc folder to try editing the clearpad file? I don't have an SD card for my phone, but not sure it is essential for these methods?
Thanks

Assuming you're on LP 5.1... System rw access is disabled by default, even with root. Flashing dual recovery by NUT is easiest way to get it. Then you should be able to move files in boot or in recovery.
