Question No Wifi - No cover Screen - LG U+ Logo? - Samsung Galaxy Z Fold3

Hi All,
I had my Fold 3 like 6 months ago, and it was weird at the beginning as it was showing LG logo on while booting, however it was working fine with absolute no issues.
now, out of the blue, the cover screen does not work at all, and the WIFI toggle does not get switched on whatever I do.
The speakers (loud and inner ones) only work work the phone unfolded or semi folded, the don't work if it is unfolded on the inside screen.
The cover screen touch works, tried to play a youtube video on the main screen and I unfolded it, I can still pause and resume but only because I know where the icon should be, but the screen has no data as if it is locked.
I think it is a Korean version that I bought from Dubai.
Model: SM-F926N
I have tried resetting network settings, uninstalling the additional apps that cam with it, reset the whole phone to factory settings, uploading a new updated stock rom, nothing works at all and I don't know what to do now.
I downloaded the recent firmware update via mobile data hoping that it would fix the issue, but nothing! now the device is running One UI 5.1.
Baseband version: F926NKSU2FWCC
any suggestions?

Doesnt have anything to do with Lg logo. Your problem is flex cable broken. How many folds per day do you usually do? For it to break the flex cable under the hinge

I actually used it slightly more than 2 months. I have a Fold2 and I'm using it intensively since bought in 2020 with no issues at all.
Would the flex cable be the reason for not getting the wifi to work too?

Flex cable is the reason why wifi, speaker , bluetooth , s pen is not working and finally the inner screen will have black line because when the flex cable gets totally cut and it will hit the inner screen. Service center charge 600$ they will replace the entire screen together with attached flex cable they will alreplace the housing , battery and even hinge. Basically you will get a new phone except for motherboards, camera, back glass, front screen

I am impressed that your Fold 2 is still running perfectly since you had it for more than 2 years.

[Q] Weird touchscreen behaviour (only works when keyboard is flipped out?)

Hi everyone,
I've had my Desire Z for little over 2 years now and two months ago (was running CM7.2 at the time) I started getting a weird issue where my touchscreen would only be responsive when the keyboard was slid out (so the opposite problem of what quite a few other people have reported where the touchscreen becomes unresponsive when the keyboard is out). The status LED would also stay off whenever the keyboard was closed, and the keyboard backlight didn't come on anymore at all. Also, I had to make sure that the keyboard was slid out during boot, if the phone booted without the keyboard out the screen would not become responsive at all until after another reboot. My earpiece speaker stopped working around the same time so I was wondering whether it was just an issue with the flex cable becoming a bit loose, but the touchscreen would consistently start working again when I flipped the keyboard out, and also the physical scroll button on the top bit would always work, so I was still hoping it would be some weird software issue.
I then upgraded to Flinny's (amazing) Andromadus ROM (build 22, complete data+dalvik wipe) after which the keyboard backlight started working again, but the rest remained pretty much the same. Since then the touchscreen issues have been getting worse, so that I sometimes have to flip the keyboard in and out again a few times, or turn the screen on or off with the power button several times before it becomes responsive again, but then it tends to work fine until I lock the screen again, with no noticeable dead spots anywhere on the screen. I've had days where it worked all day without problems (except having to flip out the keyboard, that's been a constant for the past two months), and then today I haven't been able to get the screen to do anything at all even after dozens of reboots.
I've already bought a new digitizer and am all ready to put it in (I'll have to replace the broken earpiece anyway), but was wondering whether anyone has any thoughts on whether it could still be a software issue after all, or if anyone has experienced anything similar? The thing with having to flip the keyboard out to get not only the touchscreen but also the status LED to work is just so weird and makes me doubt that it's a pure broken digitizer or lose flex cable issue, so I'm wondering whether it would be better to first try reverting to a stock ROM before taking on the messy sticky glue stuff (I should be fine but still, never done it before)?
Many thanks!
From what you describe my best guess would be the main flex cable is what needs to be replaced. Flash a touch based recovery and see if you have the issue there as well, if so its very unlikely that its anything but a hardware fault

Thanks for the heads-up, I've been playing around a bit more with software and I do manage to get the screen working again occasionally, typically after the second boot into a newly flashed ROM or restoring a backup, and only until one or two reboots later when it becomes completely unresponsive again. I've tried CM 7.2.0 as well as Flinny's Andromadus 10, and it is only complete flashing that does the trick, cache wipe or factory reset alone does nothing. The two occasions where the touchscreen worked were still limited to when the keyboard was flipped out, and it also had to be flipped out during boot, otherwise nothing would work. I've learned to navigate my way around the phone by just using the hardware navigation button, but I'll have a close look at the flex cable when I take it apart to replace the earpiece speaker tonight...
Hello,
so I took my dear phone apart yesterday to replace the broken earpiece - everything went fine but after reassembly the replacement earpiece isn't working either, which leads me to think that all those little broken bits might actually be related to some contacts being a bit lose, all in the same region. Should've thought about that earlier really since the earpiece and the LED (only works when keyboard flipped out) are both in that top region that the digitiser data presumable also has to run through before passing through the flex cable.
In any case, I also took a picture of the flex cable which is slightly bent but doesn't seem straightforwardly damaged (see attachment, that thing on the right is *not* a rip). Think it's worth trying to replace it anyway?
What was truly bizarre is that after the first boot following reassembly the touchscreen worked quite consistently for the entire evening - I thought I might've fixed a lose contact by un- and replugging the digitiser cable, but then the screen went nonreactive again at some point. I wonder if the working screen was again actually related to some software reset caused by the battery being taken out for so long? In the meantime the actual screen and trackball are still working away perfectly. Bizarre.
Just to let people know the solution to the mystery: the increasingly odd behaviour was actually caused by an initially small rip in the flex ribbon cable that got bigger and bigger - it's actually half-visible in the picture I uploaded above, only that the rip is where the cable comes out from underneath the case, and not where it's wrinkled!
Just in case it could be useful for anyone, here's the (top half of phone) components in the order in which they failed on me, which I guess corresponds to the order of the respective data lines in the ribbon cable (from the top of the phone towards the center):
environment brightness sensor (I thought that the sensor had been broken for almost a year, but as soon as I rebooted with the new flex cable I noticed how my phone stopped shining into my face at full brightness - if your brightness sensor gets stuck reporting the same (low) value this means your flex cable is on its way out!)
earpiece speaker
status led
touchscreen
screen (non-alignment with edge of screen, visual artefacts)
screen (fade to black/power interrupt)

I'll for sure keep that in mind. Mine is still going strong for the time being, but it's good to know some warning signs if I need to replace parts or if it's time to get a new phone

Replacement parts all the way, the repair was 15$ and it feels as good as new! Well, it could do with a new battery but that's just another 5..
Just realised that the proximity sensor should actually be added to the very top of the list - just noticed that faint red light when taking a phone call, don't remember seeing that in almost a year :]

That's not a bad cost at all. I know I'm going to have to replace my keyboard in probably 2 months or so (maybe sooner) because some buttons are starting to not work. Other than that fact my phone is currently still going strong for being going on a 3 and a half year old phone

Touchscreen broken after repair!

Hello,
I just got my N7 back from repair where they replaced the ME571K SUB_BD./AS board since the USB Port was not working anymore.
Luckily the port works now, but on the other hand the Touchscreen is not responding at all.
I tried restarting already without success. I also cannot reset the tablet since I got TeamWinRecovery Touch (and CWM 10.2) installed.
I can connect the tablet in bootloader and with "fastboot devices" it shows up as 077a744a.
Could anyone help me on how to flash or reset the tablet?
Ps.: This replacement was out of warranty, therefore I paid for it. The service center suggested replacing the mainboard (to make money) as well. Before I sent the tablet in everything was working just fine except mentioned USB Port.

Try flashing the JSS15R factory image.

I just flashed (with wipe) the factory image without success.
There's no response at all. Also when I try to get into recovery mode now the opened Android with the red exclamation mark shows up.
Is there a low level touchscreen calibration or something I could run through fastboot?
Anymore help would be greatly appreciated.
I'm starting to think they just put my motherboard in another tablet with abroken display...
I'd return it, it sounds like total screen failure.

That fallen android is just an image overlaid over the stock recovery menu. It just means you've booted into stock recovery. You can get the recovery menu by press/hold Power, press/release VolUp, release Power.

There are various different touchscreen software you can load via fastboot and there is a calibration file in /system/usr/idc, but it isn't clear any of these would help if your screen doesn't work at all.
You can try changing the touchscreen software, worse case, it stays the same:
http://forum.xda-developers.com/showthread.php?t=2428133
Alternatively, you can open up your tablet and check to see if the flex cable for the touchscreen has become dislodged. There are 2 cables that run across the center battery. The one that is reinforced using tape is the one for the touchscreen.
Just did a reset but it didn't work.
I already tried these different firmwares from your link but it didn't make a difference.
I guess the screen is just broken. Or is it possible that the new Subboard is not working with the motherboard and therefore the screen fails?
I opened the back but it looks fine doesn't it? Is the big cable the on for the touchscreen or the orange one?

Yes, that is the cable. You can carefully removing the tape reinforcing the motherboard side of the orange cable and seeing if there is anything preventing a good connection, possibly use compressed air to clear out the connection area. The other end of the orange cable also connects to the touchscreen underneath the usb module so you would need to remove some screws to check that connection.
That's about all I can suggest. It didn't sound like a software issue because your screen completely doesn't work.
Yes I will look at the side where I have to open screws since that is the part they changed. Mabybe they didn't connect the screen.
I also wrote the support already.
Thanks for your help, I will report back.

Hi there
I have also experienced a very similar problem. The charging port on my 2013 Nexus failed to work, I then ordered a replacement part and changed it. It is very straight forward and simple to do for a novice like me.
on replacing the pcb the charging resumed faultlessly but the touchscreen has become unresponsive, i then replaced the old pcb and the screen has resumed functionality, but charging is not working.
The part was replaced by the supplier and it has occurred again, charges fine but the screen is unresponsive. Again i reinstall the old part and hey presto screen is ok.
I am now going to try and replace the actual usb pin itself from the original failed board and see if i can repair myself.
I had also done all the resets and reboots mentioned online.
Not sure if this helps but thought i'd share as its relevant
Many thanks
Is this the n7 2013? If it is how the hell did you get the back off? I tried and was afraid of breaking something.
Sent from my Nexus 7 using xda app-developers app
It's really easy. No tools required. Run your fingernail around the perimeter of the tablet edge between the screen edge and angled plastic. You'll hear the clips releasing as you go. Then carefully work the back off. No glue, just clips. Takes about 1 minute.

Any update on how you solved this ?
I would appreciate if anyone could share the solution for unresponsive touch screen, if it's possible at all. The screen only reacts on the edges, and only to the swipe gestures, not to tapping. But all and all is the same - broken USB, replacement part, unresponsive screen.

I think this is the same issue: http://forum.xda-developers.com/nex...a/usb-io-pcb-touchscreen-calibration-t2939991
Is there nothing to "calibrate" the screen? Asus is supposed to do it for you.
I think the problem is the rev. number of the usb board.
I found this explicative video on youtube, but I can't put the link. Look for "Nexus 7 2013 2nd gen charge port replacement issue"
I have the opposite problem: I changed lcd and digitizer two times, both times touch screen was completely unresponsive. I wonder if there's a software solution for this. I know usb board have different revisions, but what about digitizers? Are all the same for every nexus 2013 model? In this case I have to think touch screen connectors on usb board are broken somehow...

I know this is an old thread, but the problem is replacing a rev 1.3 board with a rev 1.4 board. They are not compatible touch screen wise. I have heard that there is a reset tool that only Asus has that can fix this...

My kid broke the original screen and I replaced it with a cheaper one that worked great until he broke it again
Got a new screen but the touch doesn't work and I can't enter twrp except if I disconnect one of the daughther board connector ribbons (can't remember which one now).
My guess is that the screen is for a different revision board.
Any way to solve the problem?
This is the perfect thread. I have a collection of Frankenstein parts and the problem I've had with 5 or 5 devices (flo) is the sub board. Some work, some don't. I'll try the firmware links and report back.
Has any one found solution for this problem, even my Nexus 7 2013 touch screen has stopped working after I repaired the micro USB port. Actually my tablet was not charging and I figured out that there was some lose contact in the micro USB solder joints, untill then my touch working. I haven't changed any daughter USB board but just resoldered the micro USB port after which my charging has started working and I can even connect a mouse or pendrive through USB OTG cable but the touch screen has stopped working.

Damaged touchscreen - can the rest be salvaged?

Hi everyone.
After a sudden heavy rain, I got some water in my Gnex. I tried the old bag of rice trick, only to find out the USB port was not functioning any more, neither for PC connectivity, nor for charging.
Following the advice of a person I no longer consider my friend, I tried spraying some Isoprpyl Alcohol in the USB port. It did get it to work correctly, but it damaged the digitizer, meaning I get random touches on the lower part of the screen (where the Back, Home and Recent apps buttons are).
I took the phone to a service centre where they tried to clean it, but the issue remains. I'll go there today with my wife's phone to see if it's indeed a touchscreen issue or a motherboard issue. I'm not sure if I want to invest in a new screen (over $100 + maybe a new back cover since the current one has quite a few scratches and cracks) and I'm thinking of maybe upgrading to a Nexus 5 or Xperia Z (the latter being waterproof).
The question now would be, could I do something with the hardware? Like, root it, connect it to my wifi and use it as a web server, or connect it to my TV through an MHL adapter and get a "smart TV". Can I get it to ignore touches on the screen completely, and only accept an OTG/bluetooth mouse input?
Any idea is welcome

One day I got caught in a storm having my Gnex in my pocket. Vacuum and rice tricks didn't work completely, as the phone was working properly besides recognizing the sim card (Mboard issue). What I did was buy a broken screen nexus off of Ebay, and exchanged the screens.
Now I have a fully working mobile phone, plus an MHL connected - XBMC enabled smart TV box, connected with bluetooth mouse/keyboard.
Question: Why would you need to ignore touches on the screen?
As I said, after spraying the USB port with isopropyl alcohol, it appears to have touches all over the bottom part of the screen, as if someone was constantly keeping 3-4 finger and touching away at the soft buttons. Cleaning the phone in a service centre did not help.

Sorry, I missed that info. Try searching for 'touch blocker' in Google Play. Don't know if that would work on a Gnex though.
Another (hardcore) idea would be to disconnect the screen altogether.

[Q] Touchscreen behaves erratically when charging

Hey All
Today I picked up an HTC One M8.
Have set it up and only had it up and running for a few hours.
I plugged it in to charge using the charger that came with it and noticed that the screen would become erratic. Phantom touches would register making it very hard to use. Have tried it in different sockets but the issue remains.
I have tried a spare charger that I have in the house and the issue is not present.I know the HTC charger is a little different in that it supports some kind of quick charger, so its not really a like for like swap I guess.
Is there a chance that the included charger is faulty? Or could the phone be at fault?
I really don't want to have to return it but will it it looks like its the phone that has an issue.
Thanks
Well, at this point its hard to guess from here. Can you upload some snaps/videos ? It would be helpful for anyone who visits the thread. It doesn't take much time either. :good:
Is it a brand new phone? if not I think the digitizer is going bad.

Do you have a case on your phone? I have a UAG case and the charger sometimes doesn't fully click leading to that behaviour. Without the case there is no problem using the phone while charging.
Maybe the stock charger is faulty. Probably the wires has lost continuity.
I have the same issue with a unofficial charger (2.0A).
No issue with original charger (1.5A)
You are not alone
I also have a HTC One M8 with the same problem!
I have to disconnect the USB cable so that I can use the phone correctly without 'phantom touches' activating things I didn't want.
A classic example is pressing the back button will more often than not take me to google now. It's not supposed to do that. It only ever does this when charging.
Also when using any app the phantom touches will activate things I didn't want it to. Some apps will indicate which button you clicked and this is the perfect way to see this problem in action, because buttons will be clicking that you didn't even touch.
It's almost like the touch screen becomes ridiculously sensitive and even just a touch of breeze from a fan can activate a phantom touch.
My phone has done this since brand new. I've had the phone for around 3 months now. There was a software update since I had the phone and it didn't fix the problem.
It does this for me with the stock USB cable, samsung USB cable, generic USB cable, charging from AC/PC/Car it doesn't matter.
It even has the problem when the battery is at 100% with the cable connected.
The only way to accurately use the phone is to unplug the cable!

Erratic Touch on Verizon HTC One M8
This has been driving me mad.
Got Verizon Variant Red HTC One M8 near the beginning of August.
I bought a spigen clear case, a longer usb cable, and a 2AMP charger to use at work. I was chewing through the battery while playing Clash of Clans on it at work.
I pretty much always turn on visual feedback for touch on my smartphone now and noticed sometimes while playing Clash I would see multiple touches go in a horizontal line across my screen (if you do not know you play clash of clans in a horizontal position so technically the lines would run vertically down the phone)
I also have a tempered glass screen on my phone so I figured it was some kind of freak nuance with the case pushing the glass or something.
Bought a UAG Case for my phone, few days later I notice the same behavior, bought cases have a small "lip" to protect the screen if you drop the phone face down, I again figured this must be the culprit and bought a new case.
Barely there Clear case by casemate, I have had the case for 3 days and today is my first day at work since, immediately upon connecting my charger I noticed the erratic touch behavior.
At this point I realized it was never the case, it has to be something with charging in general or the specific charger I am using.
Anyone got any clue what is actually causing this issue?

Hi guys,
I have faced the issue as well. In my case, if I charge the phone using the dot view case then the touchscreen behaves wrongly. However, if I charge the phone with no case at all it works fine.
Anyway after I flashed the latest firmware (.401.6) the problem is gone. What firmware do you have?
Cheers.
Hi Guys,
For anyone interested, I have just noticed that it happened depending on the charger also.

If it's brand new, take it back for a replacement. The sooner the better because the longer you wait, the more they may think it is user caused.
I just got my phone replaced due to bad mic. I had a brand new one on release day and now I got a refurb both suffered the same issues. It's not always that it does it but it certainly pisses you off. Same symptoms as the op describes, I have yet to find a permanent solution.
This is so super irritating. I feel you. I just found out though that it occurs when I have my case on.. So whenever i use the phone when I'm charging I have to pull the case off. It really doesn't make any sense lol but this is my workaround for this bug.
I also have the same problem
It seems to occur when the phone is close to full charge. Every app goes crazy. When I unplug the charger it returns to normal.

I have the same issue with mine; I found a website which said to do the following:
Using two fingers swipe down on the status bar then touch the gear icon > Display & Gestures > G-Sensor calibration
Place your phone on a flat surface then touch Calibrate.
After the calibration process has finished tap Ok.
You should also calibrate the finger touch on your screen to deal with the keyboard issue.
Open “Settings” and go to “Language and Keyboard”
Tap “HTC Sense Input”
Tap “Advanced”
Tap “Calibration tool” (Calibrate your screen for a better touch experience)
Now you are asked to type the given sentence
One done, Calibration Complete message appears
Hit “Reset Calibration” to reset screen to factory default

It's still present, but it hasn't been as bad - I turned on the visual feedback in the developers settings, and you can watch the cursor fly all about the screen like it's possessed!
Same issue here, on the latest software. This is my second m8 with the same issues.

ZenFone 2 stuck in Asus Cover Mode with no haptic feedback after dropping on floor

I'm adding this thread to document my recent findings, in hopes that it may help others recover from similar issues.
I dropped my ZenFone 2 (ZE551ML) on the kitchen floor the other day. When I picked it up, it was stuck in Asus Cover Mode, even though I don't have an Asus Cover. I was unable to get into the phone, so I forced a hard-reboot. After playing with it for a few minutes, I was able to get the home screen, though Cover Mode would intermittently kick on and off every few seconds. I got into the settings and disabled Cover Mode, but I soon realized that I had lost vibrate and haptic feedback functionality.
I took apart the phone to inspect for internal damage, and I noticed a small hairline crack on the flex cable connector that resides on the charger port board (see attached photo for details). The now-broken connector allowed the flex cable to shift laterally from its original position, leading to connectivity issues and causing the problems noted above. I was able to temporarily fix it by disconnecting the flex cable and reconnecting it to its intended position. As a permanent fix, I ordered a new charger port board from a vendor on AliExpress that ran me about $5 USD. I just installed it yesterday, and it seems to work as well as the original.

May I know how you played with your phone to go to the homescreen? I had the same situation but mine is vibrating. I'm just stucked on cover mode.
I hit it against me hands a few times. It seemed to be enough to allow intermittent access to the home screen and settings.
If your device is still under warranty, my recommendation for you is to let Asus repair it. I purchased my ZenFone with a broken screen and repaired it, so I have no warranty coverage. That said, I'd be willing to bet that you can't fix this without taking the phone apart. If I were you, I'd open up the phone, disconnect the battery from the motherboard and the flex cable, antenna, and vibrator from the charge port board, and inspect for damage. If everything looks good, reconnect everything, reassemble it, and try it out.

Glad I could help!
I got the same problem this morning. Tried the strong magnet mtd recommended in the asus forum but it didn't help. In the end, I found that by removing the cover, and then using your finger to flick on the magnet sensor (near the back button, bottom left of screen) works! After exiting the cover mode, quickly go to settings to disable it.
Thanks a lot
I had a similar problem , but my connector have gotten wet, and wasn't broken. When i cleaned it, the mobile got out from cover mode
