Touchscreen freezes occasionally and random touch screen input

[Sophie_Laturnus]

Hey there,
I got my fp3 about 9 months ago, while I was happy at first, I soon noticed some hickups of the touchscreen that are really annoying.
The first issue is actually quite spooky, sometimes the touchscreen seems to get locked into a loop of random inputs. While I don’t do anything and just look at the screen I can watch button’s being toggled, WiFi, airplane mode, or Bluetooth are randomly switched on and off, App windows are pushed into the foreground or gibberish is typed into the keyboard. These episodes often only last a few seconds but it even got this far that I once involuntary posted a WhatsApp status during these weird happenings.
This happens more or less regularly and I cannot explain what triggers it.
The second issue started a bit later but is equally annoying. Between once a week and several times a day my screen freezes. The touchscreen does not react to any input anymore and I can only ‘fix’ this by locking and unlocking the screen again and then killing the respective app.
It has happened independent of the app.

Has anyone else experienced this? I will send my fp3 back, hopefully the factory can fix it.

Hi and welcome to the community!
Did you already check these threads if they could help you?

FP3 touchscreen experiences ghost inputs

Hello I’m experiencing some ghost inputs to my Fairphone’s touchscreen that make the phone basically unusable. They weren’t present when I originally got the phone, but seem to have developed over time. Basically the screen will suddenly start ignoring inputs, and then begin acting as though I’m touching all over in quick succession, even when my hand is nowhere near the screen. I tried disassembling the phone, cleaning the contacts and re-assembling it, however that’s not changed the situation…

Display from FP3 buggy/flickering

Hi FP community, since a couple of weeks the display of my FP3 is flickering and is moving uncontrolled. i make a short video where you can see the problem issue. This problem is in all situations sometimes and irregular. Sometimes every day, sometimes every second day or something else. Do have any Ideas? I already delete at the Homescreen the widget for Time and weather, because it was moving at the screen around when the flickering starts. Link to Video

Hi alex21,

Thanks that is exactly the same issue I have. I haven’t read the second thread yet but at least in the first there does not exist a solution yet. I contacted the support and hope they will get back time soon.

Hi there,
I experience exactly the same problems with my FP3. Twice disassembled my phone, cleaning the contacts and re-assembling it, but this doesn’t help. I received my FP in november 2019 and the problems started around february this year. I am under the impression it happens more often when it is warm/clammy weather. You too?

Hi there and welcome to the community!
Did you already try all the other tips that were given in the threads that I mentioned in my first message, to see whether it solves your problem?
For example:

@Alex.A

As it is written in the troubleshooting guide of Fairphone, in this case, perhaps you can try:

• Open your phone dial pad
• Enter *#*#66#*#* in the same way you are entering a phone number to make a phone call. Once the last character is introduced, the Service Menu appears showing you three sub-menus.
• Select Service tests > Test Single > Touch screen .
• Use your finger to draw freely on the screen and check if you can do it in each part of the screen.
• If you can see blank areas in your drawing, your display is partly insensitive to touch

Hi, thanks for your reaction. Yes, I tried and this is not the solution, my touchscreen is 100% responsive. I will send a message to the FP support.

Hi,

same problem here with a five week old FP3. The touch screen test succeeded without any problems.

I mailed FP support and hope this problem will be fixed soon cause it makes my phone nearly unusable.

Many greetings,

Jan

@Sophie_Laturnus, @Viona and @jande

I also experience touchscreen freezes and would be happy to know what the solution for you was? Thanks!

for future reference the thread I started: Random freezes (screen unresponsive) while scrolling (started after Android 10 upgrade)

Thanks for the quick reply, Viona! I will have to get in touch with the FP support then.

Hi, @rainer_zufall,

in my experience, it was very helpful that I could illustrate the problem with a video I made. The support of FairPhone was quite quick, but Cordon, the repair center, could not reproduce the problem. It took nearly a month from the first time I got in contact with the FairPhone support center to the day Cordon send me my phone back – unrepaired.

Because of the video that showed the problem quite clear FairPhone re-created the return request and told Cordon to treat the case as an “urgent replacement”. This time, Cordon reacted quite fast, and replacement took only a week.

They replaced the complete device, and everything is working fine now.

Thanks a lot jande! That’s a great idea!

I had the same experience a couple of months after I got my Fairphone:

• Touch not responding any more
• Random touch inputs without actually touching the screen

In my experience it got way better after the android 10 update and after disassembling, cleaning and re-assembling my phone.

I also found out that I could stop the random inputs simply by short pressing the power button to lock the phone and unlock it again.

In my experience it got way better

@TobiZ

I also found out that I could stop the random inputs

That still sounds like a faulty state of the phone you shouldn’t have to accept.
Did you contact support?
