Ghost inputs on FP4

Yes I’m sure a fix is just around the corner and totally not something they gave up on years ago.

Let’s hope you are right.

That was rather sarcasm…

While that’s an important sales argument it’s not the only one. To my mind, the correct treatment of workers in the industrial process, and a determined effort to reduce impacts on the environment, are even more important.

As to having to send the phone in, sarcasm aside, I rather think this is necessary for any repair under guarantee.

Sure. But I may expect a way to do it on my own – aside a guarantee promise.

You can, what make make you think you cant?

The lack of instructions from Fairphone B.V to fix the problem.

That’s painful to watch,

I have enabled touch tracking(debugging). To see the touches get recognized. My issues are not that strong, however i get in some areas under some conditions heavily oscillating touches (HW). Some other issues I had are linked to sw and GUI i think. Especially not recognised touches.

Due to that I had high hopes for the android update… but it’s delayed and my patients is also running out.

The SW “patch” was applied a looong time ago, no further updates are expected to my knowledge, just get in contact with support.

Well there is the switch to A14 which should have happened and may happen early next year.

If it wasn’t clear, I do not have a problem with Ghost inputs.
Mostly the GUI gets stuck and I can’t press buttons for some seconds.
It totally has improved but there are still some problems.

My key point was that I would enable touch tracking in the debug settings, for the people who have problems, to see what’s happening.
What the gui does and what the screen sends as information is sometimes not fully connected.

Fairphone dropped the ball on this entirely. Zero transparency on what the actual fix is. No ability to fix it ourselves. No confidence that a fix even exists. The touchscreen is impaired with software mitigation. I will never buy a Fairphone again as the company’s behavior with this defect was shameful.

It’s a shame, really, because the fix appears extremely simple, just increasing pressure on the connector. It’s a shame they didn’t even bother with adding pressure pads in the production line or offered them for affected customers. This would’ve cost them almost nothing because pressure pads are absurdly cheap. I wonder what kind of severe mal-mismanagement is going on in their company to cause this incompetence.

There is a pressure pad and the fix is definitely not more pressure on that connector. The connector is a clipping type and the pad behind it is to stop it from unclipping. There is some kind of worse defect going on. The controller for the display is build into the display unit mounted before that connector that goes to the mainboard. The display controller deals with outputting to the screen but also for sensing touch from within the screen cells. The connector to the mainboard deals with digital communication only and I doubt the issue lies there. It is far more likely that the issue is deeper in the screen and has something to do with the cut away for the camera. The main issue is ghost touches going straight down the center of the screen after all.

The biggest issue is that there is some kind of known defect in their screen assembly and they are 100% not transparent about it at all. It was mitigated by reducing the touch sensitivity of the screen which affected the usability of the device in certain situations. Like when you are not holding it but using it on a surface.

If they were really about ewaste and repairability they would have been transparent with their customers about what the issue is, what the fix is when the phone is sent in for warranty and what serial number or date codes of the screen are affected. If it is the screen or if any of them work 100% properly. I have zero faith in this company at this point as they seem to be doing exactly the opposite of what they say they are doing.

Odd, I’ve had temporary ghost inputs and could always stop it by increasing pressure on the middle section of the screen, about where the connector sits. Same with another FP4, increasing pressure on the connector stopped ghost inputs.

It’s definitely not the connector. Possibly an issue with the display panel itself

Now, after so many posts, is there still no answer from FP???

What do you mean exactly?

I have this problem so I started searching here and I see this endless thread. Of course I didn’t read it all but I was searching for an answer from FairPhone somewhere with a solution or an offer to have it repaired but I can’t find any of that.

There are answers somehow.
When you use the FP system your software is up to date, FP will not say anything else to that, They implemented a “fix” on software level (already 1-2 years ago) and those still facing the issue should get in contact with support.

Okay thanks. I actually contacted support but appear to be very busy.
