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

Hello guys,
Around a week back, my MT3G slide touch screen got unresponsive for a while. I rebooted around 2-3 times and thankfully the touchscreen worked fine.
Now, I am getting this unresponsive touchscreen more often and I have to pull out the battery from the phone and turn it on again. The last time this happened I had to do this about 8-10 times before the touchscreen would respond. I have no problems with my keypad, 4 buttons or the trackpad, just the touchscreen
I also did a factory reset and erased all the data that I had on my phone and SD card.
EDIT : I just figured that the touchscreen sometimes starts working if you slide out the keypad. But once the keypad is slid back in, it's back to being unresponsive.
My phone is out of warranty so I can not get a replacement I think.
Does anyone know what could be the problem for such frequent touchscreen unresponsive behavior. After a couple of reboots, everything returns to normal.
Any ideas ? I would appreciate any help..
Thanks a lot...
you got a broken ribbon
Hi there,
Do you mean the slide rail flex cable or the digitizes flex cable ?
Thanks
flex ribbon cable
I would say it's the flex ribbon cable which connects the motherboard piece to the screen and home button piece. I've purchased several "broken" my touch 3g slides from ebay that had either the screen shift problem when the keyboard was slid out or screen that was unresponsive/wouldn't come on. Both problems were fixed by purchasing an inexpensive flex ribbon cable like item 170747702766 on ebay. I watched a video and followed along on youtube /watch?v=-jgFHuVWlig (stop at 7:27 and reverse the process). However, my most used mt3gs is now starting to have the screen shift problem again and needs a new cable... it didn't last as long as I had hoped.
Did you try any custom roms?. reflashing/updating the device?
I guess it must be some driver issue!..
i have the same problem.
Could you fix it?
Seems to be a common issue. I've described the process of replacing the flex ribbon cable here - it's not a rocket science. Or just bring the phone to a serviceman who will do the same (if you lucky enough he could even have a spare cable, but I'd advice you to have your own bought from ebay to be sure).

Thank you for the information but another questiion that I do have is where would one get a serviceman that would repair or help repair a phone, usually the technicians are attached to the different cellular carriers and if one dosen't have a contract with them they are not likely to help repair your phone even if it is for a fee. Do you know any serviceman?
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.
hello!
Had my nexus 7 2013 WIFI for about a year. Its in a moko hard case. Yesterday it was dropped on carpet but from about 9 ft high, it continued to work. The next morning, it was power on but no display. once i plugged it in, display came on. battery was not discharged. by evening, no display at all. snowy screen once. the tablet boots up fully. ADM can locate and ring the device, it shows on my wifi router etc. But no display at all. the closest to display it came is showing the Google logo during boot up.
so it looks to me like the screen connector came loose.
EDIT: Ok, i opened the back case. Yes, it is the loose screen connector. if i press down on the gold ribbon connector, screen is on. now i got to figure out how to fix it.
can someone help me fix this?
Final edit: I fixed the display ribbon connector by inserting it into its connector firmly. everything is well.
thank you
Contact Service Center
Dude this is a matter of hardware information for which I think only the Service centers will be helpful.

if you have spent anytime on these forums, you will notice there are several hw problems for which other users have provided valuable insights. nothing wrong in asking for help
The screen didn't break but after it fell it did look like the bottom left hand corner was visible darker than the rest of the screen. Today, almost a week after the initial tumble I decide to see if restarting it would fix the problem and it did but it lead to bigger problems. Now if the screen turns off for any reason it stays off until I do a hard reset by holding the power button for 10 seconds. When I try and turn it back on the captive buttons light up but nothing else happens. When the screen is on after a hard reset I'm unable to adjust the brightness level when I pull down the top.
How likely is it that the LCD ribbon came loose? It seemed like there were issues with it before.
I'm at a complete loss for what could be wrong with it. Any advice for recommendations would be greatly appreciated.
I'm really hoping I don't need any major repairs or even a new tablet because I can't afford much of anything.
My grandson recently had a tantrum and threw down my tablet. Afterwards the screen was flickering so I decided to restart it to see if that would fix it. The screen never came back on although I could hear it start up sounds and the capacitive buttons would light up. To make the story short, i contacted Samsung and they said it would be a standard $200 repair fee unless they found a loose cable. Today my credit card was charged $59 dollars by Samsung. I guess it was just the loose cable. Note that they sent me a prepaid UPS label to send it back to them and they are shipping it back to me all within that $59 charge. Well worth it for a great tablet.

You got to remove the back and disconnect the lcd and battery cables and reconnect them after 10 seconds and all should be good. This happened to me after I got the screen of death. I dropped it and the screen did it again. So I just disconnected them both, reconnected, and everything works fine.

Can you recommend any guides & kits that I can purchase from amazon to help me take the tablet a part?
YouTube it. It is real easy removing the back, patience is needed.
Yes go to youtube for the disassembly videos. I bought a generic repair kit from ifixit for the tools. Though guitar picks can also work well.
Basically when you drop it a cable gets loose. You just have to disconnect and reconnect it.
Mine was very clearly only half connected (not in the picture which is from when I replaced the battery). I also disconnected and reconnected the battery and lcd connectors to make sure. But the loose cable was on the top left and didn't seem to be one of those. Just reseat them all to be sure.
There is another thread on here about disassembly which has pictures that I used as reference.
I've had mine apart twice. Once when I dropped it and once when I replaced the battery for poor battery performance (this really was sooo worth it).
I just received a used Note today and was about to initiate a return because the screen was completely dark but the rest of the tablet seemed to be working, including touch. Removed the back, reseated the ribbon cable, and everything's good now.
Strange start to my experience with this tablet.
Hi Folks,
I recently dropped my phone in water. Put the phone in uncooked rice for 2 days, removed sim tray, put it under direct sunlight., tried everything I could possible to dry it. After 4 days, powered on the device, it turned on fine and most of the things working as normal. I did a hardware test with *#808# and most of the tests are passed.
But Speaker, Mic (also the headphone jack) and Vibration isn't working any more. I also noticed that it is charging fine but discharging very fast, even the battery stats shows 100 to 70% as a vertical line. So, I guess battery needs to be replaced. Other than that, on normal use it is heating up.
I did some google search and few forums says, the speaker and vibration connector goes under battery and connect to the top of motherboard. Considering battery is screwed up. I guess the connector is removed or damaged may be.
Has anyone faced the same problem before or anyone can advice something?

You can't dry a phone completely without opening it. So if you are upto it, open it up (provided you are out of warranty) and disconnect all the connectors and clean them with alcohol or other suitable liquid, leave it to dry and then reassemble.
It's hard to guess exactly what happened inside, but it seems there are two possibilities:
- it could be that your top (main) board is damaged, which causes malfunction of connected bottom board OR
- you may have damaged both parts of the phone...
Either case, repairs won't be cheap, motherboard is the most expensive part of the phone.
I would suggest disassembling the device and inspecting internals. Corrosion should be visible.
Check some teardown videos (recommend Jerry Rig Everything or iFixit) before doing anything if you haven't yet.

Thank you @Explorer23 and @tnsmani will do a tear down to check for visible damage part if any.
Took the phone to OP service centre, the repair guy opened it in-front of me for diagnosis. The phone was in dry condition but there were traces of water deposits. He checked few things and suggested that needs to replace mother board as there was no signal coming to speaker receiver and this will cost ~17k.
For me replacing motherboard for such a huge cost isn't of any worth.
Any suggestion if it can be repaired in someway or shall I start to think about selling/exchanging it online.
