My apologies.
Quick tip: if you use NewPipe to watch YoiuTube videos (you should…) and your display suddenly goes dark ala FairPhone 4 bug when you flip the phone, be aware that NewPipe has separate brightness settings for portrait and landscape modes. Not the FairPhone’s fault this time 
Just received info from fp helpdesk on my ticket:
I can assure you that our quality, product and technical teams are fully aware of the suggestions made on the forum.
Currently, the experts in our Software Team are investigating the issue and are liaising with the manufacturer to find the quickest possible solution. I appreciate your patience and cooperation so far.

How long are they going to investigate the cause of the problem? Also a way of saying they have no idea so far.
They should have tested properly before rolling out the update. I can’t imagine that no one noticed it, since only a few minutes in a bright environment are enough.
I’m starting to feel really screwed as a customer.

As someone who lives near the arctic circle, I’m thankfully qiute unaffected, as the summer rarely gets hot for more than 5 minutes here

Yep, same problem here.
This should have been solved months ago. Fairphone really needs to up their game in their software support for both bugs, security and Android updates.

As a customer and affected person I agree that it should be solved as fast as possible.
But heaving read all the posts above I’m quite sure it must be solved by a firmware vendor fix and assume this is one of the reasons FP couldn’t deliver a solution quickly.

Maybe, but thats no excuse att all. I would assume that most if not all smartphone manufacturer have issues with vendor firmware, but they assure that they are fixed within reasonable time. Fairphone have been around for a while now and it’s their 4 phone so these problems shouldn’t exist.
Excuses are like buttholes, everybodys got em.

Firms like Apple or Samsung can kind of force a third party manufacturer to solve a problem, Fairphone I guess ist allowed to ask.

Fortunately, it is known that Fairphone does not read the C’t, just like the forum.
If C’t had contacted support, they might have been helped

Yesterday I installed the June update (Build FP4.SP2G.B079.20230624). I can confirm that the issue has NOT yet been resolved in this update.
Yes it wasn’t on the list of changes.

it’s ridiculous, isn’t it? As I promised before: this issue will rather be solved because summer is ending before FP is fixing it.
one could also say it’s questionable whether a company will survive for long ignoring their customers like FP does.

I made some search on the web and it seems is an issue also for other smartphones.

Just three examples, but there are other threads on Reddit and XDA

thabks for the info. I read a couple of those and it really seems that lots of different phones of different manufacturers are affected by a similar issue. But then again, not all of the same model line. It’s wierd.

Well getting that kind of coverage is rock bottom, so … sad really, but understandable. For those who don’t have access or don’t understand german, here a really short summary.
Customer contacts support after a few weeks of buying the phone. Fairphone acknowledges the problem and guarantees experts are working on it (similar to what we already read in this thread). After weeks customer complains that nothing is done. Again, fairphone stalls. Customer checks forum and realizes that many others have the problem. Customer sets deadline to fix the issue, else wants a refund. Fairphone stalls, makes excuses, refuses refund. But in the end fairphone recognises the customers right to return the product, sends a refund and a 100€ voucher.
The authors close by stating that a customer always has the right to return a faulty product within the warranty time when the manufacturer fails to eliminate the fault and acknowledges that fairphone in the end redeemed their wrong behavior.

I have a technical question for those in the know for a change:
Why does the screen’s backlight or brightness need to be throttled when the device gets hot anyway? Does it hurt the display or reduce its useful life significantly? Are LCD and AMOLED technologies impacted? I’m not familiar with the shortcomings of AMOLED, but I’ve never heard of such a thing with LCD. Or is it to prevent the screen from contributing to the device’s already excessive temperature?
Also, shouldn’t it be up to the user to decide whether they want to keep the screen going at full pelt a the cost of burning out the phone or the display, or let the brightness drop for safety? As in an “Auto screen safety brightess control” checkbox in the developers settings that the user can disable or something.
It seems a bit cavalier of the OS or driver to impose this choice on the user: it is conceivable that the user absolutely needs to see the display even if the device will die in a couple of hours if they keep going, like if they absolutely need GPS guidance after leaving the phone on the dash all day. With ths auto-dimming feature, even if it worked properly in the FP4, the device basically refuses to work at full spec even if it could if the user so chose.
I for one would prefer the feature disabled altogether, with a big fat warning I can dismiss that I says I may hurt my device. In the case of the FP4, what do I care? I can fix it later
