my screen scrolls up and down - mostly up - arbitrarily. changing the access to medium instead of short didn´t change anything. I changed the contrast (Helligkeit), but that didm´t change anything. I switched it out and back on several times. No changes. Even when I switch the fairphone on it starts flickering/scrolling. Do you know if this is (still) considered as a bug that will be solved in an update? Or have you any other idea what to do? It is hart to use messaging at all at the moment, for example. by the way - are you german? then an answer in german would be appreciated by me. thank you for your help.

I agree wholeheartedly! Fairphone is a great idea but sadly the phone has too many problems to be usable. Going back to my old iPhone 5 I’m afraid. Big waste of money too.

If your device doesn’t work, return it. You have warranty!
The phone as it is designed works perfectly fine, but any electronic product may have a couple of faulty devices among them. Just get it fixed.

So this exact bug has happened to me, it started a few weeks ago with one band on the screen not working, but now it’s two bands and what was a minor annoyance has become totally unusable… I have tried all the fixes on the forum

I have sent a message into the helpdesk, but I’m just wondering what people’s experience of the turnaround time has been? (I’m going travelling soon, so can’t really afford to get drawn into a prolonged saga in getting it fixed)

So finally this bug also got me. I already had some problems with the screen (Bright spots on the display and Parts of the touch screen dont work). I got my brand new third display and it was going crazy from the first moment.
Touch and hold delay improved it slightly.
After cleaning the contacts to the screen it works like a charm for one evening. The next morning, it was jumping again.
Switching on the pointer position in the developer options (translated from german. No idea, what it is called exactly in english) as suggested from @rynn seems to work for me. No jumps this whole day.

So I am not sure, wheather its a hardware problem, or a software problem. Maybe a mixture of both.
When the pointer position will work for more than one day, I am more or less happy with it. Its ugly, but I hope one time an update will be able to solve the problem, because it seems to be possible to solve it on the software side.
Apart from this it makes no sense for me. As far a I understand this option just shows position and some data like speed and position in the top of the sceen. No idea, what does it change.

While I am writing, I had the first jump with this option on…

I never figured out the reason. My wild assumptions are either temperature or humidity. The probability of the phone going into crazy-mode increased with duration of constant use. Maybe there is static charge building up.
The pointer-position-feature does not solve the problem, I just enabled it to visualize the problem.
I got my phone replaced today, so the next days will show if this solved the problem (I have to setup the new phone first).

Yes, I just glanced over this thread some time ago and had this feature in mind when I faced the problem last week. Thats why I gave it a try. For me it makes no sense, that it has something to do with the dissappear of the problem at my phone.
Nevertheless I dont dare to deactivate it, because its so nice to use at the moment and the jumps were gone in the moment I activated the feature.

It would be nice to get some information of the fp technicians what they think where the problem comes from. (software,
hardware, grounding problem,…)

After a few days of testing I can say, that the pointer location feature in the developer options solve the problem for me. With the pointer location I have only one to five jumps a day. Without I can’t use my phone because of the jumps.

So in my case it seems to be a software problem. At least it can be solved in a software way and now I will wait for updates.

Replacing the phone seems to have solved the problem totally. With the new phone I have not experienced the weird touchscreen once since then. So I consider this a hardware-problem.

Just a question to all having this issue, which device did you use for charging? I have seen similar behavior related to a charger with 2.5 A output. Maybe too much?!

I have the same issues, no matter what situation I enqounter these reboots, crazy touch inputs etc. I have tested numerous chargers and in my case Samsung chargers with thick cable seems to solve the famous “charger problems”. I do however have some crazy inputs anyway, often after a reboot has occured.

In my case the only time I see trouble is when screen is on. If its off I can have heavy apps in the background, navigation and such. But as soon the screen is on no matter what I do with it its a ticking bomb that sooner or later reboots.

Have sent a support ticket a couple of weeks ago but no answer yet.

Hey there, this support article might be useful for some of you with this touchscreen issue on your Fairphone 2.


A post was merged into an existing topic: Parts of the touchscreen don’t work

I have this issue on my phone, and it has now become completely unusable. it makes it’s own calls, turns on the torch, opens apps, and generally flickers about all over the screen. I love the concept, but my phone is at chuck-it-out-of-the-window point. What’s really upsetting is that i’ve emailed the support team numerous times and haven’t had so much as an acknowledgement. sad-face :frowning:

The advice that support would give you is basically what’s in this support page.
In terms of contacting support - if you e-mail them they will first convert the e-mail into a support ticket, at which time you should get an automated response with your ticket number. If you’re unlucky either your e-mail got stuck in their spam filter, or, more commonly, their response got stuck in your spam filter. The safest way to open a ticket is via the support form, but always check to see whether you receive the automated response after submitting the form (as if you don’t receive one, the actual replies will also likely be lost).

Thank you Johannes, I have had a response now. You’re right, though, they did just suggest updating software and putting my ‘Touch and hold delay’ onto ‘short’. Unfortunately, my phone is already updated and on ‘short’, so these don’t help. Hopefully there are some more ideas. Meanwhile, the ‘Kids Paint’ thing gives me very odd patterns - i paint vertically up and down the screen but get mostly lots of little near-horizontal lines all

over the screen!

You are not alone. I have the exact same behavior. I managed via Supportticket to recieve a new phone. Fingers cross the display is fine with this one.

My phone is now constantly sensing input rapidly up and down across the screen, it’s unusable. I’ve raised a support request and hope it gets sorted asap, I’m also scared I’ll lose my Google Authenticator data which would really give me a bad time.

I have tried it with one bead at the cable: Didn’t make any difference!
