This is getting weirder

Today after 7 months I first noticed some harsh touch issues while typing messages and scrolling was not as smooth

While my friends 3 months old opo has the same issues already and my friend is constantly complaining about it although it comes and goes for him

My device was exposed to the sun for about 4 hours when the temp was somewhere around 32 degrees

So after reading a little bit I tried to put it in the freezer for 15 mins and the issues were gone and everything worked flawlessly for 10 mins until it got warmer again and the issues were back

The weird thing is that my friends phone was also in the sun today with me and he doesn't have these issues for now
[ONE General] Chaosek:
I got the same thing. Normaly i don't have any issues. Occasionally it start acting weird and only one touch point works but it's sorted after reboot. Happened maybe 5 times in 5months.

But that thing with notification being pulled down after hanging up was worrying me a bit.
[ONE General] andino:
I seem to have the same issue as dieggss. When my phone gets warm, the screen becomes unusable. Scrolling gets weird, ghost swipes, etc. I can put the phone in front of my A/C vent for a bit and it will return to normal for a bit until it gets warm again. Even something like charging my phone makes it unusable sometimes.

[MENTION=4397261]vantt1[/MENTION] - Would it be possible to insulate the flex cable without replacing the screen assembly? I have the touch issue but my screen is good still. I don't have a problem taking apart my phone if I can insulate the flex cable without removing the digitizer from the LCD panel.
[ONE General] Vivek_Neel:
Same story here.

After 5 months. Even am facing this.

Touch ain't working well sometimes .. Feels like I should throw my opo. Becomes useless at that time.

Really disappointed with this issue.
[ONE General] dieggss:
Don't give up Vivek_Neel, is still an incredible phone for this price... We will find a solution, thats why we have XDA [emoji16][emoji106]

[ONE General] Vivek_Neel:
Nah!

Am not giving up.

Am just sad about the fact that its an hardware issue.

If it had been a sw issue then we would have fixed it.
[ONE General] coolguy949:
I had this happen to me yesterday really badly. I was sitting outside on the grandstands watching a race and my OPO became totally unstable - like it had a mind of its own. The top half of the screen responded to some touches while the bottom half of the screen was completely dead. I couldn't even put the phone to sleep because it kept waking itself up due to ghost double-taps. I also couldn't answer calls or respond to texts from friends looking for me at the race. Extremely frustrating issue that led me to this thread to see if there has been a fix yet. I've had my OPO since day one when invites first came out back in June '14.
[ONE General] vantt1:
You don't have to separate the digitizer from the LCD, just the screen assembly from the chassis. Re-applying the adhesive that holds the screen in place might also affect the touchscreen's status.
[ONE General] kazuken:
Would you recommend using a heat gun to loosen the adhesive so the screen won't crack when removing it? also: I can't link but this a thread from the OPO forums:

what do you think is the culprit here? perhaps he didn't fully insulate the ribbon?
[ONE General] Ninfosho:
Interesting

Would like to know if someone tried this fix and it actually worked for him

I'm afraid to do it myself ?
[ONE General] vantt1:
Yes, using a heat gun will help, but you still have to take your time and be very careful.

Did they test the screen before it was re-installed into the frame? That way, you can determine the source of the issues; whether it was from bad contact or a bad digitizer. It is entirely possible for a digitizer to be bad on its own, disregarding external factors.

Soon after posting my thread, it has been acknowledged that there exists multiple forms of touch issues. There are at least three:

Intermittently unresponsive touchscreen all the time, regardless of temperature

Problems with touchscreen after exposure to heat, subsides when cooled down

Static build-up, goes away when the phone is restarted but can come back without warning

And the point in time at which the problems arise can also be drastically different. Mine had issues straight out of the box, but your quoted users' unit only exhibited problems after 6 months of use.
[ONE General] phaninder.ch:
That was a very clean RCA :)

Even I observed that it has nothing to do with the software.

I also wanted to mention one of my observations here.

when I first bought the phone I liked the sandstone feel and wanted to use it naked without any case, so I decided to use a pouch instead. When kept in pocket the pouch protects the phone entirely even the screen. I did not come across any touch issue then.

But recently I have seen the custom back covers and was interested to use one. This time I used the Transparent Silicon case, which does not cover the screen. I have observed the touch issue every time I take my Phone out of my pocket. Was not able to swipe to pick up the call not able to unlock the device, it was annoying. Had to reboot every time I take it out of my pocket.

Then I switched back to use a pouch and I did not observe the touch issue.

I am not sure what is a technical explanation here... its more related to static electricity IMO

may be you can help... :)

Also request you all to try using a flip case or a pouch which covers the screen as well for a couple of days and observe the change.
[ONE General] Poser:
Two opos ...both experience the issue after about 3 months.

Bummer...love the phone otherwise
[ONE General] luigi0824:
I was thinking of getting this phone: -/ is it still worth it to buy this phone with all of this issues affecting it?,
[ONE General] vantt1:
The likelihood of getting a phone that is affected by issues is the same for everyone., so don't worry about it.
[ONE General] lnxpro91:
nice to see you again man, people miss you in OPO forums, there is even a thread about you on the early members forum, keep the good work :)
[ONE General] dieggss:
Hi all

Since I have arrived to Madrid I have connected the sistem monitor in my phone to check CPU and Battery temp. Battery between 28 and 34°C and CPU between 30 and 42°C and the Touch issue dissapeared. Today I went out with my friends and my phone was in my jeans poket, temperature was ok. But the phone went crazy again. I just can think about an issue when the phone is affected when submited to some kind of pressure that affects the internals, but nothing to do with temp. Any thoughts??

Hi, i'd like to know if there is a video of this tuto ?

Because i have this problem too, and my phone wasn't bought on OnePlus site so... they don't support my phone. I have to fix that problem myself so i'm searching a video of this tutorial to doing this right. Thanks
[ONE General] Stadsport:
Just spent a couple hours performing this fix and it didn't do anything whatsoever to improve touch performance.. There's something else going on. This thing has basically become unusable as of yesterday.
[ONE General] vantt1:
Have you tested the screen by itself while it wasn't installed in the chassis?
[ONE General] Stadsport:
I have not, but I'm going to pull it apart again today, so I'll give it a shot then.
[ONE General] dieggss:
Hi

The link is in the descrption. http://xdaforums.com/oneplus-one/general/repair-guide-oneplus-one-disassembly-t2979351

2 advices: 1. When taking out the earpiece, be very carefull it is easy to break it. In fact the guy in the video did it. It is the rectangle piece in the top of the mobile, next to the rear camera.

2. Don't overheat the screen, the glue is around the corners of the screen. Use a cutter (I used one like this http://www.ebay.com/itm/2PCS-Box-Cu...e-Razor-Blade-Knife-Tool-Random-/201248443624) and a sucker be patient and start from the bottom right corner. Remember that there is a very thin black frame around the display, this does NOT have to be removed.

If you don't mind wasting money you can buy all the front in here. I just ordered mine as I over heated my screen. http://vifocal.com/lcd-display-digi...h-middle-frame-for-oneplus-one-64gb-16gb.html

Good luck!!
[ONE General] Stadsport:
I tested the device again on the bench with no chassis installed; just the display, logic board, and battery, with some plastic cards separating the components. It still exhibited the problem. Does not appear to be a shorting issue, I believe the digitizer is defective. The only thing I can think of is that perhaps something melted from the heat which damaged the digitizer, but I can't find anything that would have caused this except for the digitizer itself being directly affected by the heat. Even stranger, my phone has gotten pretty hot before just through intensive use, but maybe a day in Long Beach was just the straw to break the camel's back.

Interestingly, multiple touches stacked vertically are registered fine. Multiple touches in a row horizontally are missed, skipped, and confused. Overall response (tapping & scrolling) is also way down.
[ONE General] anjath:
Totally agree that its a hardware issue. My first OPO had the issue (Jan 2015). Bought a second one last week. No touch issues at all. Seems that they have resolved it.
[ONE General] alandd86:
hi [MENTION=4397261]vantt1[/MENTION] i bought my oneplus one last month and this issue is like a nightmare for me ,, typing issue wont let me use my phone !1now am using my old s3,, till find an exact way to fix it !! any method guys ?do u think this method will fix it ?and if i separate the screen do i need any thing when put back the screen like glue or something ??

also i booked a ticket and now they are saying that nex week will come into my pc to see my issue !!but i replied that i dont think its a sofware issue cz looks like a hardware issue with so many people have it !

thanks alll
[ONE General] vantt1:
That is quite strange. The digitizer shouldn't be that easily affected/damaged by heat, especially if the heat applied wasn't hot enough to melt the glue between the LCD and the digitizer.

Sound like the only way to know whether it is the digitizer itself is faulty or not would be to buy another one...

If you have a phone to use, then you should try sending the phone back for a replacement first, because opening up the phone will void the warranty. Otherwise if you want to give it a shot, the second post in my repair guide thread covers it. You can use the black 3M repair tape or the pre-cut 3M tape (which is better).
[ONE General] Formhault:
I've been browsing the Internet trying to get knowledge of this issue for the past few hours. 5 AM now.

So my OPO just recently started acting up, after ~1 month of usage.

Do I need to separate the display assembly to fix the flex cable? So I don't have to use any heat gun, that is...

I really can't tell. :(
[ONE General] ramdyc:
So I attempted this fix but broke my lcd in the process - bummer! Anyway things got a little interesting after I received my replacement display a few days ago:

I took everything apart and taped the recommended spot on the mid-frame. Before reassembling everything I did the test you suggested and isolated the screen from the battery and other components using a thin piece of cardboard. The result was highly disappointing - even with a new display and the recommended area isolated from the flex cable the problem still remained...it was absolutely identical to the problem with the old display. Touches on the same horizontal line weren't detected and two finger taps were often detected as swipes. Crap!

I double checked that I taped the correct spot and decided to put it all back together and cut my losses. This is where the interesting part happens - once I got everything back together the new display was functioning perfectly! I can't remember the old one ever working this good. Seems I may have not been getting a good ground while having the phone apart which, in my mind, somewhat confirms your fix.

Thanks for this.

If the problem returns I will update this post for anybody wondering.
[ONE General] MBurns2:
did you buy it new or used ?
[ONE General] Formhault:
Used. The guy had it for like 2 weeks. But for almost 1 month, everything's been great. It still is, actually - just rarely, the keyboard f***s up a bit.

That is not the issue though - if it's new or used. It was manufactured in January or February of this year, so OnePlus f***ed up real bad.
[ONE General] dieggss:
Great news ramdyc! My new screen just arrived and I will place it this evening. I will also update when I finish. Well done!
[ONE General] Formhault:
If you take the phone apart to put some electrical tape on the flex cable... does the glue re-stick? I mean has anyone tried this?
[ONE General] dieggss:
Screen in place and at the moment it is going very fast and smooth. I am writing through SwiftKey trying to type as fast as I can and I am not missing a letter. I will be doing more tests through the week.

Thanks to everyone

After the screen is separated, the original glue doesn't re-stick.
[ONE General] Mitanc:
I have not tried this, but double sided 3M tape should work okay.
[ONE General] Formhault:
Sh*t :(

Did you actually try? I'm asking because a friend of mine took apart a Lumia phone and was able to re-stick the glue after warming it up. I don't know, I'm just making assumptions... he was about to do this tommrow, but since I have no glue to use...

---------- Post added at 09:49 PM ---------- Previous post was at 09:48 PM ----------

Yeah, I guess.

I just need to find a good one on eBay. One that isn't expensive, but is ORIGINAL (I really doubt those $1 - $2 things are actually 3M).
[ONE General] eViLsTieFel:
Unfortunatelly, I'm starting to see some issues with my phone aswell. I've been on vacation in Italy recently and used the phone for navigation. Sun was blazing and had the car charger connected. The phone got quite warm, but I thought, nothing it shouldn't be able to handle (I've done the same with previous phones - in those instances, when the phone got too hot, it would simply stop charging to prevent battery damage).

Since that vacation, the screen is much more unresponsive. Also, sometimes I cannot unlock the phone because ghost inputs prevent me from entering my PIN. The bottom right part of the screen seems to be affected the most.

Although, since at the same time I switched to CM12s from CM11s, it might be a software issue. I just don't want to switch back to KitKat to confirm... gah...
[ONE General] chenthu:
What's the manufacture date for your OPO?
[ONE General] eViLsTieFel:
The sticker on the back of the box says 2014-09-26.
[ONE General] eViLsTieFel:
I've downgraded to CM11s again, unfortunatelly, there really seems to be a problem :(.

Still ghost touches and swiping words on the stock keyboard (especially in the lower right region) leads to infrequent touch registers and garbage text.
[ONE General] kerheol:
I'm having similar problems in my One+ recently. Sometimes (I don't know exactly when or why) about a vertical inch in left side of the mobile is totally unresponsive. Other times bottom left corner receives touches I don't do. Usually if I reboot the terminal everything works fine for some time (minutes, hours, ...) and then everything is wrong again.

When all this happens, phone don't wake with double toch and home button doesn't register long press (just one touch or double touch, but not long press). Sometimes it doesn't work if the mobile is just horizontal over a table, but it works if I take it in my hand (vertical)

I've tried CM11S and CM12S, changing configuration, apps, etc... but nothing seems to work. Each time it gets worse... Now I must reboot the mobile every time I try to use it =(

Do you know if there is a software/hardware solution to this issues?
[ONE General] benj!:
This has started happening to mine fairly recently. If I've powered it off for a while and switch back on I can type fairly rapidly for a bit, after which it starts getting worse, to the point where I basically have to type really slowly, with a single finger, to use it at all. I've tried CM12S, nightlies and OxygenOS, with various kernels, all of which have the same issues.

I didn't buy it that long ago so thought I might just as well ask for a replacement, so submitted a support ticket with Oneplus, who say they want video proof of the problem before they'll clarify whether I can have one. Absolute joke customer server.
[ONE General] SentryMescudi:
Hi, i did the fix and i failed, i broke my screen had to buy a new one, it will be easier.
[ONE General] kyoto944:
Does this fix fix the heat-related touchscreen issues for 100% sure? It seems like it is not that easy to perform without breaking something, so I think I want a replacement phone from OnePlus One first. Although i'm not sure that a new One doesn't have the touchscreen problems, OnePlus just designed an inferior phone. Mine is only 3 weeks olds and the touchscreen problems started 1,5 week ago when it was a hot day. Because of the unresponsiveness, ghost touches and multitouch problems It feels very much like a budget phone now :(
[ONE General] AcmE85:
Same here after using it without issues since August. One sunny day outside with maximum brightness and it randomly gets unresponsive now.

Happens almost always when charging my device for example.
[ONE General] mozyman:
Started happening to me about a month ago. Went and began RMA about two weeks ago, got them videos of it. Then they wanted pics of the phone, as well as gave a zip to basically clean flash the phone. They just accepted there today that it still isn't fixed, so hopefully should have courier pick it up next week, check it out, then send me a replacement.

And all began on a reasonably warm day sitting out in the sun...
[ONE General] AcmE85:
Reading about this procedure, I have already provided them 2 videos and more than enough pictures the day after I opened the RMA ticket for my device.

Now it's just waiting. Their last response was on tuesday, telling me that my request is beeing forwarded to second level technical support "who can better assist me with further troubleshooting steps." So once again I will have to flash the stock rom. I really don't mind taking videos and pictures, but this is pointless.
[ONE General] benj!:
Yeah, pretty similar experience.

I actually clean flashed CM12S again and found the issue had gone for a day or so, so thought it might be OK after all, but then flashed a new play services and was getting ghost touches all over the shop - practically unusable. Clean flashed CM12S again and the issue remains. Weird.

I'll jump through Oneplus' hoops to get a replacement and then sell it. I'd feel bad selling this one to someone, but had enough really.
[ONE General] Formhault:
Guys, are you experiencing this?

Use a multi-touch testing software. I used MultiTouch Visualizer 2, but AnTuTu has a test for that, as well.

Problem is... when two touch points are made, on the same X axis, it goes to sh*t. Not always, though...

Is this what I need if I decide to take my phone apart & insulate the damn digitizer flex?
[ONE General] marwan91:
For those who says it's heat issue, i don't think it's heating issue, i think it's more related to humidity, outside on the sun and near the beach the humidity percentage is higher than inside, and we all know that. I don't know how grounding issues might be related to humidity also. But it does make sense. I will try to apply the this guide, but i need to find someone expert who can separate the screen from the digitizer without breaking the screen. I hope this will work. Getting tired of this touch issues already.

Edit: i've searched the web a little and i found this :

humidity and temperature both were found to be related to the sensitivity of the touchscreen. all of those who are facing touchscreen issues(including me) to matter what kind of issue you have(if its too much or just few times a day), but i guess all of them seems to be related to grounding issues, but it get worse when the temperature is high, or when the humidity and moisture in the air are on high levels.

which makes it harder for the digitizer to recognize the touches on the screen.

so most of those who lives in areas with high temp and high levels on humidity, almost can't use their phones. and others are only facing this outdoors.

I tried putting my phone on a bag of rice the whole night. and i admit it helped a little. until i went out in the sun, and the problem was back.

i hope this info helps anybody.

this issue is annoying and im trying to investigate more about it. i hope i will solve the problem soon.

Thanks
[ONE General] vantt1:
It's not 100%; it's only a plausible fix. It's always worth trying to RMA first.

Yep, it makes re-installation of the screen easier. You'll also need to put some single-sided tape here:
[ONE General] AcmE85:
At least in my case the issues also appear when I use my phone at home at medium brightness for about 30 minutes

or when it is at the charger and I use it for 5-10 minutes at the lowest brightness.

With the app AIDA64 I monitored the temperatures and noticed that it happens each time at around 43°C.

[ONE General] Formhault:
Well, I just ordered myself some extra tools I might be needing for this operation. This, this, this (they break easily), this and this (as back-up).

So... Place some of that 3M adhesive over there? Or something, anything that would insulate that area? Like... just stick it in there, on the chassis, where the digitizer flex would otherwise touch?
[ONE General] kerheol:
I've similar problem when I put the phone inside my pocket for a while. It usually works fine again after a restart. So now I restart it each time I take it from my pocket (>_<)
