[Q] Samsung GNote screen issues

Hi guys,
I'm new to this forum so I'll try to make the issue I am addressing as clear as possible.
I bought this phone for around a month now and I was quite shocked to notice the problem with my screen. Basically, it is functioning perfectly well. However, I noticed an issue while I was using my phone in the dark to check my facebook. While it was loading pictures, the screen black out and I seem to notice " cracks" appearing. I went to the service centre for a check but I was told that my phone is perfectly okay. Still in disbelief, I tried to somehow "test" my phone in the dark again. I noticed that those "cracks" appear only when the phone is booting up i.e unlocking the phone or when the phone is about to light up and they can only be seen in the dark. I'm really not sure whether it is a hardware problem with the LCD or otherwise. I would appreciate if you guys could provide me with advices.
Thank you!

Screen and signal issues since update?

Dear friends,
I am having serious issues with my HTC one m7 lately - cant remember if they started exactly after the 4.4.2 update or not.
Anyhow it seems that there is a dead spot on the screen that it doesn't recognize when i touch it. Plus the phone has been acting weird lately like it doesn't have signal and when ever i try to call from it although it has full signal it doesn't call.
Has anyone been experiencing the same problems? :crying:
My phone is completely stock, never got rooted just following the usual OTA updates.\
Phone was working great and i loved it, but now it's just unbearable- i cant press buttons on a horizontal line in the center of the screen.
Need your help.
Thanks.

Touchscreen unresponsive on lockscreen

So I had my L90 D405N repaired (whole motherboard was replaced) and I noticed something strange afterwards. The touchscreen seems to be unresponsive, but only when I try to unlock the device. It's especially noticeable if I set a pattern unlock. I can only draw the pattern successfully after like 10 or 20 tries. The touchscreen basically does not record the whole pattern consistently. This is not such a big problem when using a simple swipe to unlock method, though still occurs from time to time. I have installed the latest available software update (I'm now running V10d firmware), also had the touch firmware updated, but the issue persists. Strangely enough, none of the issues are noticeable past the lockscreen. Does anyone have any ideas as to what might be the problem and the solutions to it? Thanks in advance for any answers that might come.

Oh! Sounds like the issue of phantom touches I once had.
Tiny water particles caused random touches while swiping that broke my swipes too.
The issues persisted even past lockscreen for me.
I cleaned my screen and put on a screen guard.
I dunno if this will help you, but this is what helped me.
Turn on "show touches" in developer options.
You might see phantom touches here and there when you swipe

Thanks! Will try that right when I get back home. Sure hope it works. I'll report back with results.
EDIT: tried removing screen protector and cleaning the screen, but the issue was still there. Even did a factory reset, but the unresponsiveness didn't seem to go away. I'm beginning to think the digitizer is messed up. I'll probably take it to warranty tomorrow. Again. Unless, of course, anyone has any solutions.

I am also having the same problem after replacing motherboard...
I tried factory reset and fpashed kdz again...
Same problem..
I called lg service centre who replaced motherboard..
Said that touch should be replaced....

Seeing as the issue is probably the same as mine, your phone's screen (and digitizer as well) just has to be replaced. That should not cost anything, so just have patience. My phone is working fine after everything's been fixed.

i have an LG L90 D415, and i have same issue.
the touch is irresponsive only when unlock the screen, but when i do a call and hang up, the touch works fine, i dunno why is this. i dont know if is hardware, or software.

Run an app that tests the touchscreen and/or do a factory reset (backup first, you will lose all data). If the problem persists after a factory reset using the stock firmware then you have a hardware issue.

I have the same un responsivness.. now I cant even get into my phone bc its locked and it wont let me touch the code so what can I do to get in my phone... it did just update firmware also.. plz help I dont have money for a phone

My touchscreen does not responsive and i couldnt drag even after the initial screen unlock. I solved this problem as follow: dial this 3845#*410# (my model phone is 410, if you have 405, put 405 insted 410). After, go to HW DEVICE TEST --> TOUCH TEST --> TOUCH FIRMWARE UPGRADE --> OK. Wait a minutes e after reboot the phone. Try again if not work in the first time.

Great tip
This tip also solved my phone issue.

On a friends phone we had the same problem. At first the touch gesture on the lock screen needed a few attempts and after some time it was impossible to do the gesture and we were essentially locked out of the phone.
I'm not sure if this helps anyone else, but for this L90 (405) phone the following helped: I applied hot air (from a hair dryer) onto the device screen and while the hot air was hitting the screen I was able to do the unlock gesture on the lockscreen successfully. This was repeatable because I required it a second time as the device locked itself while I was doing some data backup. As a side note: The screen had a small crack at one edge.
Though after the lock screen various other places like scrolling through galleries, pinch-zoom and swipe-keyboard did not work reliable.

After I was finally able to unlock the phone again, then this above TOUCH FIRMWARE UPGRADE from brunolcs also solved my problem (after a second try, and removing the battery in between).
PS: One thing that helped during the backup phase before the TOUCH FIRMWARE UPGRADE. I connected a bluetooth mouse and then I was able to scroll with the mouse at important places were I needed to do backups.

Turning to the community with the same issue after I've tried just about everything I could think of. The problems started after the original digitizer was shattered and replaced with a knock-off. My touch firmware is already on the latest 2.07 version, heating it with a hair drier does not alleviate the symptoms, I've already tried four different touchscreens from four different suppliers, with some claiming for their wares to be "original" (thou what that means exactly is not entirely clear as you may know!) and still touchscreen is unresponsive on lockscreen for the first ~5-7 seconds. Once past lockscreen, everything goes away. This YouTube video depicts exactly what I mean.
Any ideas? Can any of you still on the original phone firmware launch service tools (3845#*405#) > HW Device Test > Touch Test > Check Touch Panel and see what it reports for Raw Data? (Mine says "Channel Status: PASS" but "Raw Data: FAIL".)

Anyone?

Hey,
don't know if this is the same issue, but the phone of my mother (LG L90 - D405) can't be unlocked while doing a call. Started with calling the mailbox, we were not able to unlock the phone to delete the messages. Screen didn't react at all until phone call ends. As soon as the call was over, the screen reacts completely normal.
Now the problem exceeded to any call: screen does not react, ending call is only possible, if your talk partner ends it. Screen reacts normally, when no call is made.
Does anyone know a solution? Haven't tried the solution posted above, perhaps doing a factory reset will solve the issue?
Or time to switch to a new phone, as this one was heavy used...

[Q] Q scrolling display problem

Hello all
My watch has developed a strange display scrolling problem when active watchface is displayed since lollipop update.
Please see the following video to explain the problem.
Have tried to reset via the menu to fix the problem . after reset it works for a few minutes but then it comes back. I feel this is a software fault
Any ideas chaps?
Thanks

bro..im having the same issue..have u manage to rectify it?

I was advised by LG support to return it to the distributor
they initially told me to go back to lg but in the end they gave me a RMA
Now waiting for a repair or replacement watch. Fingers crossed

I had the same symptoms as well. When through LG's customer service to get an "RA" number. I was pleasantly surprised that LG provided pre-paid shipping through FEDEX. I received it back in a little over a week. It appears to be a new watch altogether, as the the front display didn't have the screen protector I put on it, as well as the band looking pristine. So it appears that this wasn't a software issue, but a hardware failure. It was surprising that it didn't have the latest firmware installed, but I'm still happy I have a functional LG Watch R back again! Make sure you keep the invoice/receipt to provide proof of purchase for free warranty service.

I have the same problem in my particular case happen after flashing the Urban ROM ... also think is a sofware problem ... any suggestion, i dont live in the USA and sending the watch to warranty will take months....

How to fix it?
Sorry for popping this thread. I have the same issue. My watch is 10 moth old. I tried to contact LG USA support, but for some reason they don't take responsibility for it. I definitely got my lesson regarding LG support
Did anybody managed to fix this problem? As for now I have $$$ brick

My watch has now developed this problem too but i am on marshmallow.
Would flashing 6.0.1 on the watch fix it does anyone think?
I cannot bring it back to LG as i bought it second hand
Any ideas to fix would be greatly received

I have the same problem, Did anybody managed to fix this problem?

I had the same issue. To solve the problem you need to remove the mainboard from your watch and do a reflow procedure with the mainboard.
A simple way to do it is to put the mainboard in a oven and heat it op to about 100 degrees celsius for about 5 minutes. Remove it from the oven and let it cool down.
Assemble your watch and power up.

[Fixed] Screen problem (ghost touches, unresponsive touch)

I have a XT1068 Stock Retail Asia, untouched 5.0.2.
Lately i've been having problems with my screen, such as ghost touches. It started randomly one morning, and nothing i do seems to help.
Sometimes i'm unable to unlock my phone due to this problem. The back, home and recents buttons too stop working. Only 1 out of 3-4 attempts to unlock the phone works.
I somehow managed to enable visual feedback for touches and took a screenshot of what's happening (see attachment).
I cleared cache, factory reset the phone but to no avail. Please help.
EDIT - A screen replacement is the only solution to this problem.

i had this problem on my friends flooded moto g xt 1064 flashing an new rom to the phone seems to have fixed it but to do that you have to unlock your boot loader witch voids your warranty you may be able to reinstall the lollypop update by going in to recovery and install update from zip file

Same problem here after 3 months without any problem .
Now I got ghost touches and unable to unlock phone by swipe

I was just about to make a thread about this because I'm having the same exact issue and I really don't have a clue as to why because I've tried everything.
In my case it seems to happen when I take my phone out of my pocket when I'm out and about sometimes the touch screen becomes unresponsive or does its own thing. For me it happens when the phone is really hot so that might be something to consider. Maybe how the phone spreads the heat or a service on the phone when the phone is really hot idk.
It makes its own touches normally around, if you pop up the keyboard on your moto, in my case the ghost touches are around the m,delete,the dot or period and enter buttons.
Any progress from any of you with the problem or any suggestions from anyone?
It doesn't seem to happen when the phone is cold or room temperature, I think.
Edit: Additional info just in case: XT1064 rooted currently on stock moto KitKat though it has happened to me at least once on all the roms I've had. It has not dipped in water ever.

i have the same problem on my xt 1068, when the phone is warm it works fine, but when is cold or some place with conditioned air the screen starts to fail, the phone is stock so i dont know what could be the problem.
i'm going to dry the phone with a hairdryer, i remembered i saved up my phone on a closet during the nights sometimes and in the mornings the phone was wet by humidity, and i wasnt worried by that, and maybe that was the problem
i will post again if i find something
sorry if i wrote something wrong, i'm from colombia and still learning english

I have the same problem, it is probably a hardware problem because it happened after reflash stock firmware and in twrp recovery also.

It's a hardware problem. Replacing the screen under warranty fixed the problem for good. If you are unlucky enough to have voided your warranty (by damaging your screen physically or water damage, don't know about unlocking), then it's going to cost around 4000 Indian rupees (around 63$) to replace the screen. It's the only solution.
Apparently this problem is relatively common as I found out from the Motorola forums.

Ghost touch freezing our lock screen.

The ghost touches affected not only the lock screen, but also the soft buttons and the notification bar. AFAIK there is no software fix for this issue.
