Touch Screen stopped working.

Hey all First post, w00t.
New to the PDA type phone thing and learning what i can from here. Dont quite understand WM5 yet but i'll get it eventually.
nice fourm you all have here
A few post have hit the nail on the head with issues with the phone.
No hinge LED's when the phone rings is my main hate at the mo i think.
Also anyone know how to get media player to play videos in full screen? all it does is puts a black border round the video rather than streching it. This would be cool
Whats the differance between the o2 (or different) and corporate install type?
Also TomTom M5.2 is coming up all green lines, had a quick search and cant find a fix. Anyone?
Thought i'd drop on and say i've had a problem with my screen (gotta love us being beta testers ehh?) Only got the phone at chrimbo and woke up the other morning to find that the screen wouldnt tap. It seems that the screen is now tapping itself randomly, closing applications and not letting me use the touch screen at all. You cant reallign the screen.
Seems a few people have had this problem and it seems un-fixable, soft, hard resets and reinstalling the ROM doesnt work. pulling the battery out and leaving it for a short while seems to cure the problem for a short while.
If you're having this problem, call the retailer and have it replaced. Defo seems to be a hardware issue, maybe a bad batch?
I'm waiting on them getting a new one in store for me.

The screen issue does seem similar to the problem I was having.
Was on and off, but totally stopped responding early Sunday morning. Didn't start working again after numerous resets. Took it to the O2 shop today and it decided to start working again...
But they believed me, gave me a replacement and I've had zero problems with this one.
Seems like there may be some faulty ones about. Get it changed and hope they don't give you another faulty one

[Q] Somewhat dead touchscreen?

So my awesome Venue Pro with an already sketchy battery is giving me trouble.
It has only happened lately. I'll turn on the phone from standby in order to, well, use the phone. But 95% of the time, the screen will within a split second go black, showing nothing on it. Funny thing is, every key works and illuminates and you can even interact with the touchscreen as I noticed it made sounds previously when I just started moving my finger along the screen, same with powering it back on when it likes to actually show what's on the screen and it'll be on a totally different app or screen itself.
Because I bought it on eBay, Dell, very ignorantly, is refusing to even deal with me in regards to warranty despite the phone being manufactured this year, so I'm hooped for sending it in at all for repairs.
If the touchscreen technically "works", then what could be the problem?
Thanks for your help, guys.

You might want to google something like "dell ownership transfer." Seems to me there was a way to transfer the original warranty term to another person. If you can get in contact with your ebay seller, he may be able to help you out.
Short of replacement, I say the first thing you should try is opening it up and making sure all the cables are connected internally.

The next step will either be re-flashing the original stock 7.0.7004 rom in hopes that it's a software problem (unlikely if you ask me,) or ordering another DVP off ebay and swapping parts until you have diagnosed the problem.

That's the issue- My eBay dealer didn't actually buy the phone himself. He took them as a donation for his not-for-profit business so the proof of ownership is pretty much MIA.
I'm starting to believe the backlight is failing or something close to that. Possibly due to the slider being used? Not any more often than someone else would use it, though. I looked at the disassembly guide and it's something nearly impossible with my lack of tools or understanding.
I'm pretty much hooped then?

Wow, shady. I bet he took advantage of and offer like this and then just sold the phone for profit.

I can't think of any other ideas personally. Selling it off for parts seems to me like the best course. If you decide to do this, you should wipe your phone with a soft reset as you normally would when selling this phone (in settings > about > more > reset my phone.) If what you're experiencing is a software problem (which, again, I very much doubt) this might fix it. If not, your personal data is gone, and you're ready to sell it.
You may want to let the other forum members weigh in on this, but I don't think there's going to be an easy fix that doesn't involve disassembly.

I have attempted a reset + restore and whatnot, so most likely it would be a disassembly issue then.
The issue with me taking it apart would be that I'd probably do more damage that way lol.

Strange Display issue

Hello folks,
i have a very strange thing with the display of the new S7 edge from my girlfriend. And after reading arround 4 hours in the forum, i´ve decided to open a thread and asking for help.
I will try to explain what happend. The phone ist brand new and arrived today. After unboxing we running the first start process and during this i realized that the display had a "dead zone". In this zone it is nearly impossible to type or click someting. The rest of the screen works as intened.
After the start process the Nougat update runs and the issue is still there. While scrolling it looks like a lag, but there is no lag only these wired deadzone.
Can someone give a hint what this can be or is this a hardware issue?
I have 2 vids from the issue, but im not allowed yet to posted it here.
Thanks in advance so far.

You have dead pixels, which is not uncommon.
It is a screen issue which can be repaired by replacing the screen under warranty.
You just need to take it back to where you got an show the problem, they will either repair or replace.

I think he was refering to dead zone on digitizer. It doesn't register touch on some areas.
Type *#0*# in dialer and u will be prompted with test app, U have the display option there. Tap on it and U will figure out the rest. If it doesn't draw on that area of the screen, the digitizer isn't working and take the phone to samsung if it's under warranty.

Another LeEco Le Max 2 fingerprint issue

I recently purchase a LeEco Le Max 2 from aliexpress and it worked fine for the first 2 hours but after i locked it and left it on a table for a few hours and came back the fingerprint scanner wouldn't work.
After this happened to me i started to search the internet for all the possible solutions i could find like installing the original ROM and such but before i did any of the solutions it suddenly started to work again.
It started to work for like 2 seconds and then stopped again how it happened was that i had left it on my bed with the screen on and it was starting to get really hot (the room was also hot) and i started to get angry with the device and started taping the fingerprint scanner hard in the hopes of getting it to work and it started to work for like 2 secs and then stopped and since then i haven't been able to get it to work again and yes i have tried factory resetting and re calibration the scanner also i have tried installing multiple official and unofficial ROMs .
So anyway the reason for my post is to ask for possible solutions on how to fix it and also to ask what was the issue? is it the contacts or is it a defective part.

The FP problem in this phone is well documented. As are the many seemingly magical solutions folks have found for it. Search XDA and try what solutions you can find, and if those don't work, it may be the part. If it's the part, the good news is that a new FP scanner is exceedingly cheap ($6 CAD), as are most of the tools one would need to do the repair, if they do not already have them.
I posted a guide in this section here for doing the hardware replacement. No guarantees - nobody seems to know definitively what the cause of this issue is or how to fix it, but the only thing that's obvious is it's a fairly rampant problem.

it is a software issue no remplacement needed , i have post a solution 100% working

Everyone who has found a "fix" to this problem has claimed that, and it's usually not even a week before someone comes by and proves they were wrong. Certainly worth trying the solution regardless, but you shouldn't make promises that aren't validated.

Heyyo, too true @TheLastCanadian (happy Canada day btw eh?) that some may get lucky with a software fix but most require a hardware replacement to resolve the problem 100%. Your guide btw is very well detailed and as long as anyone follows it to the tee? They should be safe too.
I'm unsure how old your LeEco Le Max 2 is, but it might be cheaper to just replace the FP scanner yourself than to send it back to China for a replacement as they would probably request you to pay to ship both ways...

Thanks!
I think this is a quite late reply but first i would like to thank @TheLastCanadian for his/her comment. I already knew the thing about replacing the fp scanner which you can get on aliexpress for just under 6€
but the issue i have is that i don't have the tools to do it but even if i had them and even though it seems really easy to do as shown in multiple guides i have really shaky hands and wouldn't trust myself to do it in the
fear that i would just snap the phone in half.
Also another question recently my bottom buttons stopped working on my phone and even after factory resetting they still wouldn't work (read online that it might be a software problem)
after that i thought that maybe it was the heat wave hitting my country that caused the buttons to break/stop working but still i wanted try one more time so i cooled the phone in front of
a fan for a half hour and then tried installing the original OS (the OS that i was using was the PixelExperience for LEECO MAX 2) and then it suddenly started working. So the point of this was
to ask was it a problem with that OS or was it the heat by the way even when the buttons didn't work their light was still on.

Heyyo, for the hardware buttons? It is usually a software issue yes unless the phone was dropped and screen is cracked on the bottom half of the screen (I had that happen and the replacement screen came with new hardware buttons and they worked perfectly).
For FP reader? I guess if you're uncomfortable with doing it you could ask a local mobile phone repair shop to fix it... But they might charge you quite a bit so I'd ask for a quote and link TheLastCanadian's guide so they have an idea on what they need to do.
It's honestly not too bad repairing a Le Max 2. For me, heating up the phone enough and separating the screen was the toughest part as that adhesive tape they use is REALLY adhesive and the phone was quite hot to the touch to finally get it to separate with my suction cup.
In the guide that TheLastCanadian posted he linked a very cost effective kit that is even more fancier than the random parts I had heh so I'd recommend his linked toolkit if you want to give it a go.

Hey i know it been quite while but wanted to leave an update about the fingerprint scanner issue so here it is.
I usually wipe and reflash my phone with a cfw every few months but decided to do it now even though i already did it a few weeks ago because i downloaded and ran some infected ****.
Well guess happened?? IT WORKS NOW!! the fingerprint scanner suddenly started to work again as i was setting it up. I don't think it the cfw because i'w installed it multiple times before
and the fingerprint scanner never worked but now it does, maybe its because of its hot in my room? ¯\_(ツ)_/¯
I think its really likely to do with heat or something because the last time i got it to work for a few sec was when i first got it was after i had played some games and watched some vids in my room
which got it burning hot. Will update if it stops working again
The cfw that got it to work was the newest version of PixelExperience for LEECO MAX 2

Ghost touchscreen

Hi to everyone.
From 1 week my Mi9T has a ghost touchscreen.
How can i resolve it?

What do you mean by ghost touchscreen?

Screen responds to 'touches' you didn't actually make - like, there is a ghost touching your screen

oh, well i dont know how to fix that sorry. But maybe you touched the edge of the screen accidentally?

i have the same problem for about a week now! did you find any fixes?

me too

Me to. I have tried every possible solution. Eventually whole screen has been replaced on warranty.

No guys i dont find any solution. And now? How we can resolve it?

replacing the display is the only solution

i have the same problem, ghost touches in the upper side, near clock.. specially when phone is hot or i press the top of the phone

Im so angry ??? bc we have this phone not usable!!

It's a hardware failure. Faulty display. If you suffer from "ghost touches" you should back up the data you want to keep, and return your Device to where you have bought it from as it might still fall under warranty (depends op what the cause is, and where you live). This can also get worse over time making the screen partially unusable (which was in my case). contact the seller, or contact customer service from Xiaomi.
I suffered ghost touches at the beginning of December (owned the Device for at least a month). Tried every software options i found around internet that could resolve it, but it was to no avail. I proceeded to unlocking the bootloader, install TWRP, flash a custom rom... For a couple of days i was fine. After those few days the top part of the screen (the part with the status bar) rendered unusable, on custom rom and stock miui. Tested it and it seemed that the area increased and also decreased from now and then, which is strange. After contacting my seller they agreed on sending it back including screenshot and the tests i ran. 1 day after they received my device they contacted me to say that it cannot be fixed (or at least they didn't seem to bother as the phone's pricerange is low) and i am receiving a complete new one (this was in the weekend btw). After that weekend on monday i received the new one and it's running better then ever, even the fingerprint is much faster.
Now just as a warning, I don't say you still have warranty. i live in the Netherlands where unlocking, rooting and all that does not void warranty, and returning a product is very easy to do. But in other parts of the world the companies can screw you over so you'll have to check that.

For those who are asking what is it, juste have a look at mine in dev mode to show the touch : https://www.youtube.com/watch?v=-ZApYI9otJI

This happens to me only when I'm charging the phone, still annoying, , I think it's something to do with the voltage and could be fixed with a software update.
