[Q] Constant screen flicker/overwriting? - G3 Q&A, Help & Troubleshooting

Hi everyone,
So I've had my LG G3 for about 3 months now. As of this morning, a particularly bad case of flickering set in on it, with the screen overwriting other parts with transparent versions of other sections of the screen. I've tried restarting the phone, pulling the battery with the phone on and off, removing and replacing the SIM card and SD card, etc. to no avail. This is particularly mild compared to earlier; before, it would "scan" a single line across the entire screen, fade to a solid black screen, or other major errors. The touchscreen and all physical controls still work, and as far as I can tell only the battery is a problem. I'm likely to be sending it in for tech support, but if between now and Monday I can find a fix, that'd be greatly appreciated. I've transferred my SIM card back to my original phone (a near broken Razr Maxx), and since restarting after that, the issue has almost completely gone away.
I have a recorded video of the problem, but I'm unable to post due to the link restriction on new accounts.
Any ideas?

[Q] Answer inconvenience phone use, No power display

Very good day
I have a query, I have a HTC Touch PRO 2 RHOD300
The phone is counting on the next problem happens when you try to turn the screen by pressing the button on top that will not start and if you take the pen side of the phone just turn on the lights in the lower keys where this call, Windows key, Back and Finish. The phone returns to regain normal when a call comes in after the returns to be shut down and locked and not back on the screen.
In other cases there is the disadvantage that remains off, open the phone to expand and to use the qwerty keyboard and this light comes on but no screen and if you call the phone number that shows no signs of life with this call More on the other side of where you are calling is heard that he was calling.
My question is whether they have a patch for the solution and if someone else had already reported this fault, this problem is being presented to several phone numbers of friends and wanted to see whether if they had a patch to fix what they could afford to apply it to the phones have this fault.
If in case anyone has a solution for this above I would appreciate very much.
Funny... I have been experiencing this same problem just recently. I have another identical phone and replace the sim card in it with the same results. It doesnt appear to happen to the phone when the sim card is not installed. I have tried hard reset, selectively installing programs, thinking it was a programing problem with one or another, but nothing I tried seems to change the problem. Any help is appreciated.
Thanks.

Note that for my part I've been trying to give solution to the problem and have identified the following place your sim but the connections do not let my ISP leaves your network connection as my job to your phone so you do not use the 3G data network, thus the problem will not happen.
To me this is what happens, the phone went dead, but if you remove the stylus from the side, the lower lights are lit but not the screen, but if you make a phone call to your cell this and respond, but entering Idle this again locked again.
HTC have written to me but these have not been resolved.
I am in Guatemala and I used 2 different companies and the problem persists.
You friend in that country is, and have only confirmed this problem also began to give you on Friday May 20? because that was the time when many telephones HTC Touch Pro2 here began to have these symptoms.
Yes. Friday would be correct.
So if the issue is global, it is the end of the world of mobile
This doesn't appear to be a new problem though. If you search on "Screen of Death", it is quite common. However, I have tried several of the solutions that I have come across, with no go. It is complicated by the fact that we started experiencing the problem at the same time.

[Q] VK810- random "loading" icon appears.

I bought and second hand Verizon LG 8.3 a few weeks ago for my wife. She used it trouble free for about 2-3 weeks, but just last week, it has started acting weird. I began with random crashes to desktop during some of the games she plays (Soduku, Wheel of Fortune, etc.) After reset, it wasn't crashing to desktop, but the screen goes blank temporarily then returns to normal. When reading a Nook book, the screen will go blank (not black, just words disappear) and the loading wheel appears. After 1-2 seconds, it returns to the normal page. Additionally, occasionally, the Nook settings bar appears randomly, as well. It has a Otter case, which I removed to test, but the issues persist. I has the stock 4.2.2, and I have not tried rooting or any major changes as of yet. I have tried factory reset 3 times now.
I contacted LG, but they just want it shipped back with receipt (which I don't have), or else they can't do anything. Any ideas here? Can this be hardware related? Should I try rooting first? Wait for the Kitkat update to see if that fixes it, etc?
Update
I just thought I would update, in case anyone else runs into this issue with the G Pad 8.3.
Turns out, it was the SIM card. After purchasing it, the 4G service was still active for a couple of weeks (Verizon's 4G is fast, btw...) so it remained in the tablet. It took a several days after the service ended for the issue to appear, and then it dawned on me; even though the 4G service was turned off, that the SIM may affecting the system. Sure enough, after removing the SIM card all is well. Wish I would have thought of it before resetting the thing like 10 times, but better late than never... :cyclops:
Maybe this would be obvious to others, but having never used a SIM card, it never even occurred to me. So just a heads up to anyone buying a Verizon LG 8.3; make sure the SIM card is removed, if you plan on not using the cellular service...

D850 Screen unresponsive randomly HELP!....please?

Hello everyone, I just recently got a G3 and it was working fine for the 1st 2 days, no issues. I was sending a text to a friend earlier today and after it sent, it completely froze. After doing a soft reset it took forever to boot up. Once it booted up, it seemed to be fine. about an hour of operation, the screen looked as if it was freezing because it wasn't recognizing any of my touches. i decide to flip the phone sideways to see if it was actually frozen but it changed to landscape just fine. Sometimes it comes back to life then goes off again shortly after, and other times, i have to soft reset. I've tried the following to no avail.
Took the phone apart and cleaned both connectors.
Re-flashing the rom.
Trying 4 other roms.
Returned to lollipop stock.
I can't figure this out for the life to me and worked my ass of to be able to buy this phone. Any help would be appreciated as I can't afford to spend any more money on it!
I also have this issue, it's been ongoing for a few weeks. There will be short periods where it can work just fine, then it just freezes up and does not register any inputs. The content on the screen continues to run as if nothing happened (videos and games keep playing). Turning the screen off, waiting a couple minutes, then turning it on can sometimes give me another minute of use until it freezes up again. Also of note, when the screen is unresponsive and I press the power, it will dim to very low levels for a few seconds before going fully black. When the screen is being responsive and I press the power, it goes straight to black, as is normal and expected. From my testing, I've concluded:
1. This issue is not app dependent. It can occur at any time, and is not caused by alarms or overlays, such as blue light filters.
2. The issue is not from the specific battery I use. I've switched out between multiple batteries and used different chargers, none seem to affect the frequency of freezes.
3. Temperature may have something to do with this. When waking the phone after it's been sitting out in the cold, there seems to be a higher likelihood that it will be unresponsive. This is not always the case, which makes concluding that the issue is hardware related difficult, but some correlation seems to exist.
4. This issue started occurring shortly before I began having the popular "SIM Card Removed" issue, which I've yet to resolve (though can sometimes get the SIM card to work)
I am running stock 6.0 D85030p AT&T. I will post here again if I figure something out, but I have been trying for weeks without much success.

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

Click to expand...

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.

Hardware key control mode / How to full clone?

Hi all,
The gf's LG G3 took a fritz a few days ago. Been working absolutely fine from new (18 months), but now it comes up with "Hardware key control mode" on power up.
I have tried the 3 finger power up to turn off this mode, but it just comes straight back on once booted.
I have also replaced the screen and digitizer - but still get the same error. So this suggests a fault on the mobo itself...
Question: From adb commands alone (since I can do nothing really on the phone!) if I get a replacement LG G3 (or motherboard at least) is there a way to copy *absolutely everything* from the faulty one, and restore onto the replacement one?
I mean everything - settings, apps, backgrounds, ringtones, sent/received texts, photos (ones on the phone obviously, not the SD card) so basically once I put her SIM and SD card in, the gf would think it's still the same device? I bought it her as a present and she would be devastated to think it's totally goosed and needs to be changed - not to mention the heartbreak if she lost any photos
Thx in advance
