Fixing an old issue. Advice needed. - LG Optimus G Pro

Hello there. Roughly 4 months ago I bougth a second E980 as a replace for an old one who got some strange issues on its screen (random/ghost touches and -progresively- dead digitizer, display was ok), just to find that the new one started to show the same issues.
I tried to replace the digitizer alone on the older one and that worked only for a short time, and now I wonder if changing the whole digitizer+LCD display could fix the issue...what do you think? had you experienced a similar problem in the past? is adviceable to buy the whole screen replacement? is this a software problem? should I pass of this phone and curse to the skies like a mad man?
Sorry for the crappy grammar.

Maybe another Touchscreen issue, Please Help, urgent

Hi,
yesterday I bought a G4 H815.
I have the following problem: If my phone is on the bed next to me, or lying on a table, the touchscreen response is terrible. If I'm holding it in my hand, there's no problem. If it's charging and so lying on the bed, there's no problem either. It sucks when scrolling on Facebook (it doesn't scroll sometimes, but opens something instead, sharing, commenting etc), when typing a message, and even when waking up the screen with double knock.
I searched a bit on the internet and I found a guy, who had a problem like this but with another phone. He had a grounding issue after having the touch screen changed.
What could be the problem here? Maybe grounding, or some kind of isolation is faulty? Or is it the ISSUE everyone is having?
I bought the phone yesterday, so I'd like to send it back to get a new one, but the shop tells me it's not a "problem" because a bunch of lg g4 users have this problem and a new update from LG will fix it..
But I don't think it's the same thing. What do you say?
What I don't get is that it's only producing the problem while lying on a flat surface (table, bed - the phone is lying still, that's not a problem), but when I hold it, or plug it into the wall, it's perfect. That's why I would think it's some kind of grounding issue, although I'm totally not competent in electricity.
I opened the service menu, dialing 277634#*# and I did it there:
I took a few photos with my Optimus Black, since I could't take any screenshots of the issue:
this is with my phone lying on the bed:
and here holding it in my hands, producing no problems at all.
Send it back and exchange the device.
Thanks, yesterday I've sent it back. I'm waiting now for a new one... I hope that the will send me one quickly.
I made videos of the problem..
lying on the bed, the touch screen responds very poorly:

Hi. I also bought a g4 and am having the same issue. Have you received your replacement? Does it work?
I had the same issue with a Galaxy S6... it's definitely a hardware issue.... get it replaced ASAP

Seems like similar issue as mine. The members here claim that it may be due to the curvature of the phone.
Yup, you need to get a replacement.
I had this problem with my wife's phone and mine. but i changed to a different USB cable (not stock) and the problem does not appear!

Weird Screen Behavior and now totally Unusable, Need HELP!!

Hello Friends,
Three month ago my nexus 5x touch screen started to work awkwardly, sometimes its perfect and sometimes it doesn't work at all until number of locking and unlocking the phone it would work again, until yesterday the screen suddenly rotated upside down!! and then purple flashes then nothing at all, not even google logo just white or purple screen.
So I want to make sure its a screen replacement issue and not a motherboard issue, and where can I buy an affordable one that ships internationally.
thank you guys in advance.
P.S: screen used to work perfectly in recovery before the purple thing.
And If it is as I expect a Hardware issue. I'm out of warranty or a repair point where I live, Do you think buying a new screen frame will fix it for sure or it might be another hardware failure?
Anybody??!!
Did your phone water damaged? I have the same issue but some water was poured on my phone 2 months ago. Now I am waiting for my replacement screen.

Problem with screen flickering

Hello. I start writes at the beginning of what the problem is. My G3 is very unlucky. Underwent operations 3 exchanges panel (display + touch). After the final exchange of the phone came two days after what appeared screen flickering. Having traced the various forum decided according to the recommendations of users heating the main processor. Not happily operation failed. The phone does not respond to anything. Now I have a chance at a low cost to get a G3 with a broken touch to transplantation motherboard. Only now is the question. Is it really the problem lay in the motherboard whether there is a possibility that the display itself is defective. Sorry for a bad English. Thank you gentlemen for your interest in the subject and I hope that you will help me with this problem. At the end I might add, with the phone still went smoothly in the display white spots. Have a nice day guys!
yes the problem is in the motherboard -- the SOC heat cause that issue
So the change of the motherboard will fix it ?
Okey tommorow or later arived to me brake screen g3 and i swipe motherboard and type there result thanks again for yours interesting this thread.
It's either a:
A) Dying battery
B) Bad screen or not a proper connection
C) Motherboard
I would check the screen and battery first as they were the first tampered with.
Taking the motherboard from another G3 is a good plan. You can also try applying a thermal pad to the back plate.
And for ****s sake, for the 1000th time:
DO NOT PUT YOUR MOTHERBOARD IN THE OVEN.
And expect a repair that is... As a means to try to boot it up for a couple of minutes to backup your data, sure, suit yourself.
If it is the same problem that others describe it is probably the motherboard. I just bought a new one and replaced mine. Like a new phone now. You can read my comment on another thread here for more details.

Is the touchscreen of the 10 junk?

Well... Finally I can't hold back.
My phone is now like 2,5 years old, maybe a little bit younger.
A 3/4 year ago a had a problem with my display, it had a non responsive touchscreen on the upper part of the screen, about 1cm.
I send it to htc for warranty, it seemed to be replaced and I belive them, since a few scratches disappeared.
But now I face the same problem again!
And not the first time since the replacement.
Check my sig, there is a post about this problem and a "solution"
Electroshocking the display? Dumb, but it seemed to help.
Since I replaced my battery, I had no problems, but I used some cheap double sided adhesive tape and today I changed it to some t-7000 glue.
No problems at all....
A few minutes later a part of the screen is unresponsive again....
Well... I shock it again, restart the phone, bend it as little/much possible...
Working again.
Somewhere I have read, these problems are maybe pressure related, that's why I bend the phone a little (not much, not even visible)
Well just now, the time I wanted to sleep... I discovered this unresponsive screen part again!
I have no piezo handy, so I just try to press the screen and bend it a little....
Won't work....
Now, with a partial dead touchscreen and no solution that worked before...
The only thing that I can do... Write a rant about this...
Back to the title...
Is the touchscreen htc using for the 10 such a piece of crap? Or why is it failing like this?
It is not like I do brute force on my phone, the first time I experienced this problem, I had done nothing wrong... It just failed Suddenly...
After battery replacement... Okay, I was sad since I really tried to be as cautions as possible, but I was aware I can break my phone.
But it was running!
All these problems are occurring after some amount of time after I did anything hardware related to the phone!
Right now I just watched 2h on YouTube while charging....
And bang, Suddenly the touch is not working completely!
I have never heard of such a behavior before, nor I encountered similar problems with my other phones that I took apart.
I really love the 10... But why is it failing on me like this?
Especially after I got a fresh replacement display?
This is bull****, I really start to belive, the hardware component for the touchscreen of this phone is junk...
I really need to sleep now... Good night...

Is this a question.....post it in the Q&A section......
Edit :
I have mine 2.5 years now, no issues at all. There will always be people with problems and always people without. Consider it luck. That's it, not sure why there should be a whole thread dedicated to the obvious. So either get over it and buy a new phone or sort it with HTC......
Cheers.
Same. Have had my phone since launch and the only problems i had were with battery... and they were software issues so i was able to fix them... with the amount of times my phone has dropped i'm surprised I haven't faced more issues. For me the hardware on this phone is 10/10
Well, wasn't about to star a QA on this topic.
More like a discussion, which was right in the place I posted it. Even the title is a question, it wasn't obvious a normal question I really need a answer about.
@bilibox
I love the hardware too! The phone is awesome, else I wouldn't have changed the battery in the first place.
But even before touching the phone interiors, I had problems with the touchscreen.
I thought it may be a drop damage, since I had a few accidents with it.... But never something really bad, only dropping from like 20cm bed etc.
It survived every time!
My first faulty touchscreen was without any incident at all.
I belive to remember I just charged it over night, last drop was a few weeks ago...
Won't say it can't be the fall it has taken damage by...
But since I got a replacement screen and a few month without any incident the same problems starts to happen, but after changing the battery, I fist thought I damaged something.
But after opening it up again it worked without issue.
Right now I need the electro shock therapy like 3 times a day to have the part of the screen responsive for a while.
Even my phone is not in use, it will fail again....
This failure is soo random and fixable permanently (after I put it back together when it was working, fixing it with double sided tape, it worked) it still fails after gluing the screen in the backcover....
I have orders one last replacement part, the screen incl. Touch and stuff, to have this repaired....
If this won't work... Well... I was recommending htc to everyone who wanted a really good phone with awesome support in case of a damage.
I can't do that anymore, since I have these random problems with only the touch....
Yesterday it brake while watching a few videos on yt....
I really really hope... HOPE!... This is only a hardware issue...
With the new screen I even get some "original" adhesive to put it place... Maybe this will help....
The failure is obviously connected to pressure....
Since I was able to fix this problem by "bending" the phone. (bending... I was trying to bend it, I just pressed the screen and the edges... Really tough phone we have here)
To new readers:
No I don't want a answer on the title question, just tell me about your issues with the hardware of this phone.
The only thing i read all the time is "bending" and "dropping" a fall from 20 inches or even less distance would not hurt the device....yeah of course, from what planet do you come from.
This whole topic/discussion/Q&A is a absolute waste of time.
I'm very sorry for all the inconvenience you've been through with the device but complaining about it here is useless. And after 2.5 years of existence of this device there would be and endless list of topics here at xda about hardware failure if that would be significant. So i would recommend using the existing ones......if you can't find any that would confirm your bad luck.
Get over it.

Read well my friend...
After the warranty repair I haven't dropped the phone at any time.
And well... Instead of nearly 2 years with dropping, the new screen only survived a few month (5-6) without dropping.
The only thing I have done was replacing the battery.
And my repair was easy as f., since the replacement adhesive of the last repair was crap and wasn't really sticky at all.
There was no bending at all while the repair.
The bending was a way to fix the unresponsive parts of the screen as a temporary solution.
I bet, if I pry the screen out again, the touch will work again without problems...
Even if I need more force since my last repair, since I have properly glued the screen in place.
It is not like I don't know what I am doing... Tbh, I have no idea why the shocks work as a temp solution...
But for the rest, I am more in the electronics as in Android itself.
And if the screen fails at these random reasons, there has to be a malfunction with the way of picking up the signal from the touchscreen layer of the screen...
By using deforming force this problem gets better or worse it seems this connection seems way to fragile... I will look into this once my replacement arrives.

Chinese refusbished LG G4 with bootloop problems

A while ago I had the bad idea of buying a refurbished G4 H818p on a chinese store. It was so cheap I couldn't be happier when it arrived and it apparently worked like new.
A month later I had to read a lot about bootloop and how to fix it as the phone suddenly stopped working.
I managed to disassemble the phone and I found that a new dissipator was applied to the main board but the quality was so low the whole repair lasted just one month. I tried to fix it with some new pieces of copper and thermal paste but it didn't work. So I went to the software solution and applied a tot file that made my phone to not use two cores. The phone resurrected but now I have some random green points on the screen after using it for a while (they are not dead pixels, as they change always) and many apps just crash after loading them the first time (they stay there if I load them three or more times). Are these problems related to the excessive temperature in the main board too?
Can I fix them too?
Thank you.
