Buttons pressed randomly

Hi,

Last night my phone developed the same problem, when I plugged it in to charge - but it persisted after removing it from the charger. I tried rebooting to factory mode to do the tests, but the random selecting of buttons was continuing during the factory reboot, so I couldn’t even get to the point of “item test”. Additionally, I can’t even use the power button to turn the phone off or reboot it when on - I have to remove the battery. When on, it doesn’t respond to touches at all and is entirely unusable.

I’m really frustrated, since I need my phone, and am a bit disappointed that this issue seems to be a relatively common problem. Does anyone know of any other things to check for?

I’ve sent a message to the support team too, though not sure how long it will take for a reply given that it’s the weekend.

my touch screen sometimes act really weird- i try to open an app, and a different app is opens…
things like that. i suspect that the glass screen protector is the cause, but sometimes if i restart the ff
the problem is fixed for a while.
what should i do?

You should perform the touchscreen test to find out if its a hardware issue.

FWIW, my 2 cts about the charger and random touch problem in case you really need to charge and text at the same time:

  • The problem only occurs with some sockets in my house, so perhaps try another.
  • Sometimes the problem goes away when rotating the charger in the socket, switch the polarity so to say.

I was unaware that there exist grounded chargers, I’ll keep that in mind, thanks.

I was watching a Youtube clip todayon my FP1U (not touching phone, all working fine no damage or incidents). The phone started behaving as if screen were being swiped / buttons pushed. Turned off and on again several times - now the screen will not move past the security swipe code page. It does not recongnise my touch and responds as if someone is trying to enter the wrong security swipe.

I’ve tried removing battery and SIM - no response. I now also see a warning logo in the top left corner. Do I need a repair job? Anyone had similar experience? Very frustrating!

You should perform a touchscreen test.

Thanks Paul I have done this test. The phone responds very slowly to touch - it generally registers touches in red squares at the edges but not reliably in the centre. Lots of ‘imaginary’ touches picked up and my single touches not picked up. If screen is like this I imagine I need repair? Could it be a software problem?

A positive touchscreen test indicates a hardware problem. Take a screenshot of the test and send it to support. If you didn’t break the screen yourself and you still have warranty they’ll probably replace it for free.

Ok thanks have done this. FYI screen test detected same pattern of picking up a ‘fake’ vertical swipe on left hand side as happens when phone in normal mode.

So I tried the test, and even getting to the test was a problem. I could only move throught the menu with volume down? Nope, my phone could get everywhere without me doing anything. When I managed to open and perform the test, the red squares in the right down corner got green within 2 seconds, again, without me doing a thing. The screen responds to my touchs, but also to non-existing touchs.

Btw, my phone is not charging, I am holding it like I always do… I have it 1,5 years now.

I’ll also write to support.

It’s normal that you can only navigate with volume down in testing mode.
The result of your test suggests that it’s a hardware malfunction and since you have your FP for less than two years you’ll probably get a replacement screen on warranty. :slight_smile:

Hi everybody, since 2 days I experience exactly the same problem with my FP1U. It flashes and reacts autonomously as if the touchscreen would be used by “ghosts-hand”. I got a brandnew screenmodule from fairphone in May 2016 which I installed properly and was happy with it until now. Also I experience the USB-jack-problem since 1 week now. Could those two problems be related? If Iff I should open a seperated topic, because its a FP1U and not a FP2 problem, just let me know. Thanks! Axel

I moved your post here since you are talking about the FP1. Please do the touchscreen test to determine if it’s a hardware issue.

thank you for this information @paulakreuzer! I did the touchscreen-test and had no “ghost” movements in the screen which was displayd during the test although I realized, that the area of the “return” and “home” button was not included in that test - am I right? after the reboot and unblocking my phone, I experienced “ghost-action” again, which I think are mainly related to exactly the “home” and the “return” button beneath the visible area. Is there anything else I could do or should I contact customer service straight away? Thank you for any information which could lead to the solution of the problem. Thanks! Axel

edit: I did the test again and realized there were “ghost” touches in the far down right corner. also some areas of the screen did react only by touching them repeatedly. So yes I have a hardwareproblem… :frowning:

Just a short update on my issue with the “ghost action” on my FP1U screen. I made contact with customer support first online and then by phone. After describing the problem and sending pics and videos, I got a repair and also a rebuy/trade offer for a new FP2 for a lesser price. I opted for the repair as my I was still happy with FP1U when it worked properly. So I shipped the FP1U to Fairphone and got an imediate repair ticket, which included the exchange of the display unit (for free as it still had warranty) as well as the motherboard (around 180€). I was not sure if I should spend that money instead of accepting the purchase of a new FP2 for a discounted amount. Finally I opted just for the display unit exchange and will now take care of the motherboard issue (USB connector) by myself. I let you guys know how this works out. But for now the “ghost action” issue on the screen is solved :slight_smile:
