Ghost Touches on my Zenfone - ZenFone 2 Q&A, Help & Troubleshooting

Hello everyone,
Since yesterday i have been experiencing ghost touches on the top part of my screen., and it keeps increasing. I have not been able to find a solution uptil now.
I am prism barebone Rom (Stock). I was using google launcher, tried removing it, but not of much help.
I am not able to understand whether its a Software issue or a Hardware issue. Should i take this to Asus, i am already rooted, so wonder whether they would help or not.

if you got your device bootloader unlocked , your warranty void but i think there is some article how to getyour bootloader relocked but idk i havent got my device unlocked yet. but another story if you havent done anything to your device, just bring it to asus and get repaired

I am also a prism barebone user and I have the same ghost touch problem time to time. I started noticing this after I received my last update (165).
My bootloader is unlocked and there is no way to relock the bootloader (except flashing the dark splash screen to make it appears to be locked) as such I can not repair my device with warranty. I could do out of pocket repair though.
I did search on xda , internet and found so many postings without any proper solution except send it back to Asus repair service. (Asus changes the digitzer part)
Here is what I found.
1. The Ghost touch (it also called Phantom touch) started noticing around December 2015, after taking the last update. So it could be software related. Asus has aware of this problem and we are hoping that the next update would fix this problem.
2. Everybody who had their warranty repair said that the problem was fixed. So it could be hardware related.
- Some said that they download and flashed the latest firmware and it solved the problem.
- Some said that they replaced the ZenUI with Google launcher and it solved the problem.
Here is one I thought it is useful so I copied it to my note pad. I did not copied the name of the original writer so I don 't know who wrote it.
"For millions of ASUS Zenfone users having Ghosh Touch issue there are 2 temporary solutions you may try:
i) Slightly Bend your Zenfone towards front and back - this should instantly solve your ghost touch issue but only temporarily (be very cautious while bending your phone as excessive bending may damage your screen)
ii) Do Not Keep your mobile phone in the pockets of your trousers as it may again bend your phone and cause ghost touches
iii) Even if the ghost touch is fixed try running the SMMI Test (Touch screen Test - draw a big 'S' from top to bottom of the screen and repeat it from left to right side of the screen) frequently to find if it is really a hardware issue, while testing you may find sometimes the tests are passing while sometimes the tests are failing. If the Tests fails frequently please take it to local ASUS authorized service center immediately for a hardware fix, take screen shots of the tests before visiting the place. "
I used to have screen and phone cover. I took those off .
I no longer put the phone in my trouser pocket.
I did bend the phone sometime.
I am waiting for the next Asus update.

Hmm....i too looked it up and found that it could be software related.
So just for testing purposes, i have started using a custom rom. Uptil now i havent faced the ghosting issue. I will also try the methods you have listed.
I have a back cover that is pretty tight and a tempered glass. Will try removing those too.
Thanks a lot for your feedback!

In settings there is a setting to increase screen sensitivity if you are wearing gloves. Have you made sure this is unticked?

Yes, i did check it. It was unticked.
BTW i am cm13 now, and havent noticed any of the ghost touches for some time.
But now they are back. I assume it is hardware related now. Going to take it to asus.

i encountered the problem, i replaced asus launcher with nova launcher and problem was resolved

Start Menu Pop Up

The Start menu pops up as and when it feels like it. It normally happens when writing sms. While writing, the start menu just pops up and it's bloody irritating.
I've tried hard reseting without any additional softwares on at least 4 different ROMs from here & the problem still persists. I'm convinced that it's not a hardware problem cos Karmba 7.2 Non-Touch ROM does not have this problem but the ROM is way to heavy which causes the PDA to slow down.
Is anybodyelse facing this problem? Is there a fix or something to this? Appreciate any help & advice i can get. Thank you.
P/s: I don't get this problem on my TyTN II, Dopod 838 Pro & Touch on custom ROMs
not really ment for the trinity forum is it ?

Well, there has been a number of posts on this known Trinity weakness.
I also experienced quite an irritating behavior as well some time ago.
Look through the threads, you should find them. Personally, I do have the impression that since I use FTouchFlo, it is far better. However, this only is an impression ... not sure it helps,, but at least you should not feel like "I am the only one with this damned f..... thing" !
same problem
I have the same problem on my phone! specially when writing sms with phonepad and no stylus. You are right. It`s unbelivable annoying. the problem seems to dissapear when you are using the stylus and not flabby fingers..
Me 2 :'(
I am also having this problem.
I've noticed that it only happens when i press lightly on the screen, not when i press hard.I Suspect that it is a fault in the digitizer, and somehow it signals to the device that the upper left corner of the screen is pressed.
My suggestion for a possible solve is to write a little program that prevents the user from clicking on the start menu on the screen, by introducing a "non-click" zone where the start menu is on the today screen.
As i allways use the "windows" button i can always access the start menu. This, i think, will prevent this fault from happening.
My only problem is that i don't know how to program native C.
I have not tested my above mentioned theory, but i would wery much like to. So if there is anyone out there that can do this program, i would be very gratefull.
Scann69,
I would hate to make you nervous, but when I encountered the same problem you are havin it was the start of somethign terrible. My Trinity was back and forth from repair for over 6 months!!!
They replaced the screen, it worked for almost 2 days. They replaced the screen AGAIN but when it came back the 'vibrate' function of my poor Trinity didn't work. They then replaced the mainboard and now things appear to have settled down (but i've only had it back for a couple of weeks now).
My suggestion would be send it in for repair. Good Luck

this problem have been there since i bought the phone a year ago. Htc replaced my mainboard around 5 months ago because of some cameraproblems. I think Beebo has a good point about the digitizer. that would surtenly explain why it dont happen to me when i use the stylus. the problem mostly occur when i use my fingers on phonepad while writing sms..
i also got this problem...quite frequent
first, the changed motherboard, nothing solve and still happen quite frequent
second, changed lcd screen, happen less around once a day or 2 days once
i found this problem quite easily by using finger but now even using stylus it also appear....
how u guys solve this problem? got send to service center or just leave it?
Yep this isn't a WM6 issue
Yep it is a Trinity issue
Yep it is a hardware issue, something to do with the LCD screen. Some have said it gets worst if the phone is heated.
You might have seen improvement after installing touchflo because of the increased reaction time to touch.
No I don't know a solution

but this not the way to solve it. this is the trinity's hardware problem. why need us to bear this problem.
what the technician do is change lcd touch screen. it will not solve becoz after a while it will come back. i go to service center until i tired
after monitoring, it still popup at least once a day....
i really don't know how they solve the problem....damn frustrating....
i have this problem too, but only recently.
who gonna be help?
first prob is the start button popping up, next step is that it continually does this and infact will not allow any screen inputs....as in total piece of #$%(ing crap. I have a dopoid d810 in canada , started 2 months into owning the phone , htc will not service it, and pretend like they dont know why this is happening ( there is info all over the net about it, many people think it is the chip that is improperly mounted to the mouther board that controls screen input). AS Dopod has the service contract on this phone htc will not service it for me and of course dopod does not have international warranty. HTC screwed me hard and long.....I have never been so disappointed with a product in my whole life ( even cereal box xray glasses were better than this)
i had this too on my m700, i think it is an issue with the screen mounting, certainly heat and things may well affect it. Possible the casing pushing the top corner of the screen or something.
I had mine replaced by orange.
rjefferis,
what did orange replace for you? touch screen or whole unit pda?

Yes, all you said are right.
the trinity, there are two problem:
one is the LCD mounting, if you touch the LCD slightly, it will push the screen to the corner as click start menu. for the people who met the problem once in few days, it is all right.
the second problem is serious, as you said "worse when heated", that is because a resistant near CPU is designed in wrong place. the problem will happen freqently everyday and worse when phone is hot (cuz the NTR resistant). once it happens, it will get worse and worse till the motherboard breakdown.
i know some people they replace the resistant to fix the motherboard by them self, and they write down all the progress. if some one really handy and insist to fix the problem, i am happy to translate the progress in to WWE
that day i asked staff at service center, they said never occur this problem so far
i asked htc staff(my friend), he said don't know got this problem. seem like htc don't know this problem....

Screen fades to black/Flickering (Issue)

Sorry if this has been posted somewhere but i haven't found it. Has anyone had this issue where your phone turns on and it just fades to black? I've found a few people online have this problem. I had to send my phone back and just got a replacement yesterday. It seemed to work fine for a few hours. Then i went ahead and rooted it and the problem came back to this new model they sent me. I wonder if it's a DPI or motherboard issue when you root. I have read that it is a batter issue. Another person says it's the motherboard. And another even says it's the screen that need replacing.
Here are a few videos:

Mothernoard and LCD. I'm guarantee this for You. I had the same problem with lcd, but it was broken. But i had almost the same symptoms mate. So, probably you'd buy a secondhand G3. Maybe ... I dunno right now how much will cost you a new mother board with the LCD. I'm really sorry mate ? ? Take care ??

Hey, I had a similar issue then I disassembled the device and checked the connectors, board and other components, then I procceded to only reassemble the device and it now works perfectly! I believe it was bad connection maybe caused by dropping (guilty lol)
Hi
finally I found the perfect solution for this issue,
No need to call LG company
No need to replace any part of your smartphone
No need to pay for anything
this is a software issue believe me or Not !! it's not about any piece of hardware ........... yeh it's look like a hardware issue but it's not
I have an LG G3 and I was have Exactly the same problem .
All what you have to do is :
* 1 Root your phone [ be careful in this step ] .
* 2 Install TWRP recovery mode
* 3 use TWRP recovery mode to install CloudyG3 2.5.
That's all and your smart phone will be look like LG G4 , fast,smooth, and New

I find this implausible. It is most certainly a hardware issue. Software cannot fix a physical hardware (overheating) problem, although it can manage power more efficiently.
What tests did you perform before and after in order to fix the problem on the device to which you refer?

If it's not software related then it is probably a ribbon cable/connector issue...which would help explain why people are seeing recurring failures after replacing LCD's and motherboards.
I followed this youtube video and it fixed my friend's flickering LCD...it took about 15 minutes total and cost $0... http://forum.xda-developers.com/verizon-lg-g3/help/lg-g3-screen-fading-flickering-fix-t3326092
If it doesn't work the 1st time you may have to add some thickness to whatever you put on top of the camera connector. I just used a rolled up label from work and stuck it on top of the camera connector, reassembled the phone, and it's been working fine for about 3 weeks now.
Good luck
Solution for fading and flickering
I found a Solution for the flickerinv issue, you don't have to put something between the cam connector and the case.
1. Open the phone
2. Remove Motherboard
3. Search for a hairdryer
4. Blow hot air on the whole Motherboard until it heats up and you can't touch it.
5. There's a chip which doesn't sit on the Motherboard correctly, heating up fix this.
I don't take any response for demaged Motherbard or so on.
Sry for grammatical mistakes, I'm a german guy. :*
I spent days of googling and there are only temporary solutions for this problem.
After testing my phone for 2 days in different conditions I realised that the screen is going crazy when the light is changing too much.
If you do a sensor calibration everything will go back to normal:
-enter in Hidden Menu (model dependent)
-select Device Test
-select MT
-OK to restart the device
-OK and do not touch the screen for few seconds
-go to Individual Items+Power (you must push power button when you select this item)
-select Sensor Test and take care to not block the proximity sensor when you make the selection
-you will be instructed to cover the sensor (usuallyy twice)
-go down to Backto the Main List
-select Normal Boot+power (again you must push the power button to make the selection)
The phone will be restarted and you will have a working phone (I have 8 days without any screen issue)
So, let me get this straight,
The problem with the G3's screen fading is a hardware issue related to the CPU/GPU. The fact that someone puts a paper on the camera connector and it works is due to the fact that the tension applied to the motherboard flexes it and it makes the BGA balls re-connect. The only way to fix it is to heat it up gradually ( I've used a professional Bosch Hot Air gun and some special paste ) and before reassebly, to put a metal plate with some thermal paste between the CPU and the metal case. This way the CPU won't overheat that bad, and it will be pressed into the motherboard, minimising the risk of this to reappear.
For any other questions contact me anytime.
Thank you for your instructions - surprisingly it worked. You missed a step - the menu should be ELT test after getting into hidden menu.

Did this and now have an insecure boot error, going to give a fresh kdz install a go
I followed the baking instructions and the phone seems to be working again. At 375F (solder melting point) for 7 minutes. Then I let it cool in the oven for 30 minutes before reassembling the phone. Seems to be working.
Maybe, Maybe not
I started messing around with the settings, and since my phone, right now, doesn't have service, I turned data off. Where the screen would eventually fade to black, and became unresponsive, It would darken a little bit, then snap back. I said hey, why don't I get a cpu app(I used setcpu). I lowered the speed to a little over 1900, made sure it was using ondemand(using noop), turned off automatic brightness(set it to 61%), and rebooted. So far no flickering, fade to black, unresponsive touchscreen, with no touch, installed greenify. I'm gonna let it charge, and see about the battery life(thank goodness I installed greenify). Yes the phone's rooted, and twrp is installed, and xposed is in, but never changed roms, just stock. When I get a carrier for it, and it does it again, then there maybe something there.
Hi all,
I had issues after I acedentilly fried mine using maps, spotify and wireless charging when driving with it in direct sunlight. I didn't realise until I nearly burnt myself picking it up. A few hours later it started flickering and fading off suggesting to is an issue either caused or effected by overheating.
Anyway i took it apart and baked the motherboard at 175C for 8 minutesminutes and it worked flawlessly for 3 weeks until it overheated agian. Did it at 200C for 9 minutes this time and its fine, see how it lasts and maybe get some thermal paste and make some adjustments to keep it cool

[HELP]Part touch screen not working

So until day before yesterday, My phone had been working fine, no issues at all. Then suddenly I started getting ghost touches. I thought i twas due to the some smudges on screen. Tried cleaning it, but the touches would remain. Turned screen on and off used to make it go for sometime. Rebooted, the issue seemed sorted. Then yesterday, I started to notice that the part where ghost touches were occurring, touch is not working. Rest part works absolutely fine though. Tried the screen touch test in service test in service menu, it showed that much part to be unresponsive. So is there any chance I can recover by testing with some software or replacing digitizer(which comes with screen I think) is the only option? I have attached the a screenshot of the touch test. The black rectangle in center is the one where touch is not working. I have removed the screenguard, so that was not causing the issue.
I'm on stock, rooted and xposed. Also tried reverting back to a clean PRF(rooted and recovery), but same results were obtained. Once or twice I was able to get a single line of touch across, but that's it.
for a week or two my phone also started getting ghost/phantom touches in roughly the same area. I haven't taught much of it until now, your post has made me concerned that my screen too will stop working.
keep the thread updated if there's any new development

Tried a few apps, none are able to register touch in the specified region. Will most probably have to replace digitizer. How is Your phone fairing?

I wasn't able to solve the problem, and I'm using as it is for now as I can't spend much on the phone. One user had said that even replacing the digitizer might not work, not sure why though. Were You also rooted and/or exposed?

welcome to the club
my situation is the same as with @Mirhawk. I'm using the phone as it is until I can put aside enough money to buy some other phone.

Nope, neither rooted nor xposed.
I sadly can't anymore really use the phone, it started from one day to the other. Luckily I already ordered a new phone a week ago, it just needs to be delivered....

Unresponsive touch screen...

Has anybody noticed an intermittently unresponsive touch screen after the latest OTA? I haven't had any problems since they fixed the original problem way back when.
It goes completely unresponsive and I have to reboot several times to get it to work until it stops again. I'm assuming this is a hardware issue on my end since I haven't heard anybody else talking about it but I just wanted to make sure.
I think I will try a different kernel and/or ROM to see what that does.
Hi,
I have the same issue here, it started a few days ago for me. Up till today I just had to reboot but now it seems completely blocked... I will try again later but this is becoming really annoying
.
I had the same happen to me about 2 months ago. Happened around an OTA.
In the process of trying to replace it. Tried flashing recent factor images but no luck
I've had exactly the same issue as described. Hardware buttons work fine, but no response to touch. Started intermittently and got progressively worse until there is no touch response at all.
The first time this happened, I contacted google support, and they arranged a replacement. That was in June.
The replacement device has now developed the same fault, which progressed in the same way as the first device.
Just got off of the phone with Google support, and my second replacement is now on it's way.
Fingers crossed for 3rd time lucky.
Same thing...
This has started to happen to me -_- replacement is on its way. Doesn't seem like the problem is being fixed more or less just addressed...

Ditto here. Just received "refurbished" (was actually new--factory wrap, unopened) replacement unit two days ago. Had my initial Pixel C about 10 months with zero issues. Then, a couple weeks ago, touch responsive became spotty, typically cured by putting tablet to sleep and waking. Progressively got worse until no touch response whatsoever. Physical buttons worked fine. Factory reset, tried flashing prior OS versions, etc. Nothing worked. Stock / unrooted.
But, Google customer service was very cool about the replacement.
How were everyone able to contact Google Support? I have the same problems with the touch screen, but am not able to find a way to contact Google about it. I had bought mine straight from Google Store.

I had the same problem after an OTA Security update yesterday. Booting into recovery and erasing cache fixed it for some time, then problem reappeared. Can be fixed by repeating the procedure. Seems a software problem to me.
Same problem. I can't even get it unlocked now as nothing registers.

I guess this is just a hardware issue because it happened to me twice and both times Google provided me with a new tablet. The only advice I can give you is to contact the support because in my opinion nothing can be done at our individual level...
Will they still replace out of warranty? Purchased Dec 21, 15. Tablet had been flawless until yesterday.

Hmmm I highly doubt it, but you can give it a try. Did you try to factory reset yet, just in case?
Yes, initially​it was slightly working as of Wednesday and I factory reset. No change, but it registers no touches now so I can't even unlock it.
Google is getting me a replacement so I thank them greatly for that.

yeah, google did the right thing by shipping a replacement, bill3508. i just hope whatever hit your device is isolated.
2 issues I've come across lately with my Pixel C tablet:
1. Touchscreen unresponsive
The tablet has lost touchscreen responsiveness. When I touch the screen, nothing happens. Buttons pressing ok - it works.
I have connected the device to the PC by Vysor app. Using a mouse from PC I can manage. I tried diagnostics in programming options (I've turned on show touches on touchscreen and localization of the pointer) but no touches detected however mouse moves yes.
Rebooting didn't help - many trials. Safe mode neither.
I haven't done a full recovery to factory settings yet. I am afraid of loosing USB debugging mode. Looking foreward to finding software resolution before warranty replacement.
2. Power button doesn't light up the screen - possibly backlight fault (software?)
After few trials with power button the screen shows up. Sometimes I try reboot but the problem returns. It is randomly, sometimes after one pressing power buton, sometimes lastlky after few trials withe few rebooting.
When I put the tablet on light (a lamp or sunshine throug window) I can see the view of the screen darkly. So there is the view but without brightness.
Android 7.1.2, N2G47D
I have the same problem now.. However I've noticed the following: When the device is in the case which covers the screen and has a magnet, the problem will persist. If removed from the case and left for a day outside, the problem is gone (so far at least). I will return the device for a replacement and hope google can replicate the issue. Anyone else using a case with a magnet?
Yes I have the same problem and also a magnet case. But for me the problem is not gone, after removed from the case and left for a day outside .
Now I get a replacement from google.
Should I now no longer use a case with magnet? Is the case the reason for a broken pixel c?

Question I'm facing fingerprint option missing issue in my mi 11 lite device.is there any solution? I have tested CIT test already. how can i solve this issue?

Please help me to solve this issue.
Try this step again, Go to Settings > About Phone > All specs, tap kernel version many times, test fingerprint sensor. Visit the service center if the test fails or install android 11 new version.
I'm sure this is a software problem. I've never been this careful with a phone in my life and I also have the same problem. Unless the update somehow tucked with the motherboard idk. But my best option is to wait for another update to roll out

I bought this phone and after some months i faced this stupid issue too. I've been very careful but had to send the phone to a service center. They said that they changed the fingerptint sensor. Since then no more fingerprint issues...
Same thing with me, it was hardware. After only 6 months of use, I had to send it to a repair service under warranty. So far I had no issues with the sensor.
same here, fingerprint sensor is missing from menus. I will send it to a repair service.
Well it seems the only solution is to send to repair and i think warranty will cover that.. Seems like factory problem :/
But I don't care anymore, since if i send it, it would take maybe 1-2 months, so during that period i would be without phone..
Possible fingerprint sensor flex cable damage. Try restarting your phone while gently pressing around finger print sensor.
this is not a software issiue i have the same issiue and i changed the sensor 7 months later it still works great
I was also careful with my phone and after 3 months of buying it, the fingerprint unlock option disappeared. I couldn't find any solution and tried everything I could. In the end, I took it to a repair shop and they told me that the cable connecting the fingerprint sensor to the motherboard was damaged. They said it was due to a design flaw by Xiaomi. I would recommend you doing the same thing if the rest of things dont work.
The same problem started for me. I had used it very carefully until this time. As you mentioned, it seems to be a chronic problem. When I did some research, many people mentioned that it was fixed with a software update. My sensor disappeared a few days after the last security patch. It could be a coincidence, of course. For now, I am waiting for the upcoming MIUI 14 update instead of sending it to any service. I hope it solves the problem or I will probably send it to the service.

Unfortunaly its hardware problem bro. Button needs replacement , and there is no guarantee how much time will work even replaced. I hate to send to official repair shop, as it will takes weeks, and i have no spare phone. So i just use double tap to turn on the screen aswell to turn off the screen on display
