Screen dying already?

[dsimic]

No, sorry. I can monitor from now on if it helps, when the phone is plugged.

It would be very useful if you could, please, monitor the CPU temperature, using the commands described in this earlier post.  For now, it would be good enough to pull the values manually every 30 seconds or so while using the phone, and immediately after the phone exits the suspend, and put the values into a textual file or a spreadsheet.  I hope this isn't too much to ask you for.   If you find that a nuisance, I can write a script that pulls and saves the values automatically.

After we get a rough baseline established that way, we could apply some thermal-related configuration to your phone, after which you could do some more measurement and a general assessment of the thermals and the perceived performance, for both low and high CPU loads.  This would provide a very valuable, independent insight into the effects of the general configuration that will be applied to the phone by the userspace thermal management daemon I'm working on.

Usually not very hot, but the upper third of the screen regularly gets warm. It got quite hot when I was trying the convergence feature, when I received the phone. By the way, the phone was discharging even though it was plugged. It also gets hot when I occasionally try something heavy like for the phone, like FreeTube or Pure Maps, or when evolution-alarm-notify gets stuck.

As we know, the upper third of the screen is the area under which is the A64 SoC, which is the primary source of heat in the PinePhone.  Consequently, increased CPU load heats up that portion of the screen, simply because the CPU cores generate more heat under load.

Did you use the HDMI port on the official dock while trying it out?  Using the DP-to-HDMI bridge IC inside the dock makes the dock use additional power, which may end up with the dock providing no power to the phone.  However, it's a bit strange that the phone kept discharging despite the charger being plugged into the dock, if I got right the setup you used; what kind of charger did (or do) you use, and what was (or is) its current rating?

Yes. I think there was a time when the PinePhone was suspended after a few minutes, now it is 1 minute. Once or twice I temporarily needed to make sure the phone didn't go to sleep and forgot to restore the setting right away, but not for more than a few days.

However, I usually leave the phone plugged the whole day and then it does not suspend. It might get hot without me noticing but I don't think it is usually the case (I would have noticed I think).

I'd suggest that you keep the phone suspended to RAM when unused even while a charger is plugged into it, because suspending the phone allows it to cool down.  As a side note, you can always initiate the suspend to RAM "manually", using this command:

Code:

echo "mem" > /sys/power/state

Sorry, I don't remember well. I first thought it was a problem with the screen protection and haven't much thought at first. It started before this thread was posted, probably in February or March, so probably 4-5 month.

Roughly speaking, it should then be safe to say that the screen delamination started after a prolonged daily use, if you agree.  In our world, filled with short-lived smartphone models, four to five months of daily use is usually considered "prolonged use".

I don't have any device to take convincing pictures right now, but here's one attached. It first started at the top-right corner. Then it spread across the upper edge of the screen and then on the left edge, starting from the top and spreading to the bottom. Quite like the picture given in the first post. It has now spread on the whole bottom and right edges of the screen. I noticed today that a second "layer" has started spreading at the top-right corner. I hope it won't spread too much, it is manageable for now but if the entire screen gets affected it will probably be a bit tough!

I'm not even remotely close to being an expert when it comes to the glues and screen lamination, but this sounds like a rather serious development of the issue.    As a note, no picture was attached to your last post.
