Today I found that someone has a similar problem with the Volla Phone 22 : https://forums.ubports.com/topic/10983/volla-phone-22-very-laggy-performance/5?_=1756284607730 . Maybe both problems are caused by the same thing.

I have a similar problem with my Volla Quintus, see : https://forums.ubports.com/topic/11263/frame-rate-and-slow-animations-movies .

I am already in contact with Volla about this. But because "laggyness" or "low framerate" is quite subjective (not easy to measure in technical terms), except you can record the screen in high framerate and without aliasing, it is not easy to talk about and to discuss this problem.

Well, maybe not a 20 years old smartphone, but a smartphone that is 15 years old.

@TotalSonic : Thanks for the answer!

When I watch, on my Volla Quintus with Ubuntu Touch, movies on youtube in Morph or when I simply scroll a web-page up or down, the framerate of the movie and of the scrolling-animation (I think, there are better words for this, but I hope you understand) seems slower than with my old Volla 1 and much slower than with my Fairphone 4 with Android. Because of this, watching movies makes no sense and scrolling a web-page up or down makes me feel like using a 20 years old smartphone with new software.

Does anybody else have this problem?

On the page https://devices.ubuntu-touch.io/device/algiz/ the wireless connection is listed as "working". So I think that someone must have tested a wireless connection between at least one monitor or monitor/adapter combination and a Volla Quintus. So at least this monitor or monitor/adapter combination works for sure without testing on my side.
Does anybody know, how I can find out, which combination was tested and thus produced the check sign at the topic "Wireless external monitor" on the page https://devices.ubuntu-touch.io/device/algiz/ ?

(Or is it unrealistic to think that this was tested? )

@kugiigi : Thanks for your reply!
I will buy a monitor anyway in the near future and I do not need it necessarily for interactions. It would be no problem for me to buy one that is compatible with the Volla Quintus. But this implies that I can find a monitor that works or a monitor/adapter combination that works in physical shop and they let me test it with the Quintus.

The device page https://devices.ubuntu-touch.io/device/algiz/ says that the Quintus can be connected in a wireless way with a monitor.
Does anybody have any experience with connecting (in a wireless way) a Quintus with an external monitor? Or does anybody have experience with connecting a monitor with a Quintus or has any ideas about this topic?

(I heard that miracast monitors are generally supported, but I am not sure if it is a good idea to buy a miracast enabled monitor and find out the possible problems or possible drawbacks later)

Thanks for the answers!

I think, I will not install the "Screen Recorder" app because first, it does not record sound (but that is what I need in the first place) and second, because it needs "Full System Access" rights to be installed. I think, access to the screen, to the sound and to the user's files in the user's directory should be enough. I do not see, why full system access is needed.

In the comments of the Screen Recorder app i saw the comment "works great, thank you, no longer have to record my remote desktop". Maybe this is a solution for me. Does anybody know how to connect to a UT phone via remote desktop?

(Another solution, which would be fine for my use-case, would be to simply record only the sound. Is this possible in some way?)

How can I record a screencast with a smartphone which runs with Ubuntu Touch? I want to record the complete screen for about 20 seconds including sound.
(I own a Volla Phone Quintus with UT 20.04 OTA-9, but I think, this does not matter in this context)

@Charly , this problem seems not to happen to every volla. So, if I understand you correctly: you had these problems and they went away for months now?

Hi @AppLee , yes, I wrote a mail and got an answer yesterday.

They say that these screens are not available anymore and that a screens swap would cost 120 Euros anyway. They also wrote that I can get a new Volla with 20 % discount on the regular price. But I think, they are not really addressing this problem and I do not want to have the same problem again in about 1 or 2 years.

@sven , following your advice, I removed the SIM card and restarted the vollaphone. The problems did not go away. I restarted again and tested again in a time of about 24 hours. The result was that the problems did not go away.
Now I use my vollaphone with the SIM card again. But I really must find a solution, because as time goes on the phone gets more and more unusable.

@Ian , maybe it's a problem of the original Vollaphone and not of Vollaphone X. Or something, which we did not find out yet, triggers this problem after some months of usage. I also did not have these problems from the start.

Has anyone found a solution (or a workaround) for the ghost touches problem? (The funny thing is: I already owned my Volla for a year before the problem surfaced. Now, with time or with each update, the problem seems to get worse)

@Ian , thanks! I found out that Biometrics are disabled on my phone and that there is no finderprint ID installed. So the finderprint scanner cannot be the reason for the ghost touches.

I have problems with these "ghost touches", too. I tried to find a way to disable the fingerprint sensor, but I cannot find anything about this on my Vollaphone or in the internet. Where can I disable the fingerprint sensor?
Has someone found a solution for the ghost touches problem yet?
