@kugiigi Got it! Thank you. It seems a lost battle though.

On the one hand, if the wireless mirroring is so disappointing I guess, and I understand, the developers will focus their efforts on more useful issues.

On the other hand, if wired mirroring depends on hardware, there is nothing to do, since it seems that the new promoted devices (except FP4) are not prepared for such feature.

I really miss convergence for a tablet. The only ones that have a wired mirroring feature are the old BQ Aquaris M10. I own a BQ E4.5 and Morph crashes a lot (although I will keep using it until its pieces fall apart). I suppose it is due to its low RAM, but I do not think a second hand BQ M10 will do better now. My presentations rely on HTML+CSS+JS so I would create a webapp with Weber, pointing to my presentations.

"We expect to start shipping the Volla Tablet with Ubuntu Touch at the end of the month. Ubuntu Touch runs perfectly on the device. We will provide two features with a system update:

• The easy installation and use of Ubuntu desktop apps with Ubuntu Touch Noble based on Ubuntu 24.04 LTS
• The support of VoLTE"

With the answer @DenMoore got, I wonder if you have to buy a tablet with Volla OS and then instal Ubuntu on it by yourself (via system update). In their shop you choose the OS but it seems that they will send you the same.
I would appreciate more transparency. This community will not be blinded by marketing but by specs and freedom. I do not mind delays and I prefer real facts.
@kugiigi, I pretend to project interactive presentations, in which I will draw and I will manipulate 3D models. A noticeable lagging is undesirable.
I mentioned wireless connection because the Lenovo Tab M10 HD 2nd Gen Wifi 4G/64GB has that feature. I prefer being free of wires, but if the connection has a noticeable lag, I would not mind a wired connection. However, as I see in the devices page, among all the phones only Fairphone 4 has that feature.
Will it be one or another (wireless or wired) be extended to the other devices?

Hi,
According to Volla, they already are shipping the Volla tablet.
I am interested in the "Wireless External Monitor" feature. Currently it is not working on their phones. The tablet does not have its page in ubports website, so I asked Volla and their answered saying that the devs were working on it.
Does anyone know (@TheKit @deathmist ) if this feature is in a "priority" list or it is considered secondary/difficult to address now?
Does anyone already receive it? Please, share your opinions. Thank you.

Take a look to this and this old posts.
Maybe your issue is related to what they described.

Thanks @arubislander,
I can see that Wired External Monitor is not supported, but Wireless External Monitor is.
Assuming that the projector also has that feature, I suppose you connect directly to the projector via WI-FI? In that case, can you also surf the web while projecting or your connectivity to the www is unavailable?

Can this device connect to an external projector via the usb-C port?

@Charly As Rinigus mentioned in another thread:
"At present, you have to use default location, close the server, move it to the location you want and make symbolic link from the default to the new location."
I have done it and works flawlessly.

Dekko2 settings have an option to delete messages older than a given date (one week, one month). Settings --> Accounts --> Manage caché --> "Clear now" button.
Don't know if it really works though.
UTTweakTool shows that I have a caché of 11.25GB!!!, even though my BQ4.5 does not have so much storage.
After clearing messages older than one week following the previous method, UUTT shows a caché of 10.96 GB. Something has been erased, but obviously there is something wrong.
You can clear the caché in UUTT but beware! It also erases the configuration, so you must introduce all the accounts from scratch. I think there alraedy is a bug opened with this issue.

@lduboeuf I had a look to your link. I can see the following line:

framework: ubuntu-sdk-16.04.5

However, your CMakeList.txt file shows:

    set(CLICK_FRAMEWORK "ubuntu-sdk-20.04")

I guess it does not matter since you can build the app.
I am struggling with this issue. I installed clickable in my desktop machine (20.04) but want to develop the app for my BQ 4.5 (Xenial, 16.04). Although I have manually changed the lines in the apparmor file from 20.04 to 16.04,

{
    "policy_groups": [],
    "policy_version": 16.04
}

it still complains when I tried to build the click package:

 - security:policy_version_matches_framework:phonehome.apparmor
	16.04 != 20.04 (ubuntu-sdk-20.04.1)
	http://askubuntu.com/q/686347

The provided link does not consider this ubuntu versions, but I guess 16.04 should be valid. I have consistently introduce

    set(CLICK_FRAMEWORK "ubuntu-sdk-16.04")

in the json file, but without luck.
I do not know why clickable insists in 20.04, when none file has this version number typed.

In the OS category there is a topic about background location that may be interesting for your GPS issue.
On the other hand, I think nobody would had though about disabling the volume buttons. You may want to use them for your headphones even with the phone locked.

I am happily still using a BQ E4.5 so there is no other option.

Why have I been downvoted?
I was just reporting an initial weird behaviour, but finally a succesfull performance.

Hi @AmauryDBZ. Sorry, I am not a developer, so I cannot provide any hint. I usually use a trial and error approach. You can try uninstalling the package and reinstalling it again.
Actually for me, the first time it was not properly installed because I lost the wifi connection. I tried again and although I had some doubts (see posts above) it works.
My phone requires some time to connect to the satelites, but once it is done, Activity Tracker followed me.

It works.
I tried it with Activity Tracker and records my position with the phone locked.
During the first try, the location switch turned off automatically whenever I turned it on. But now the switch and me seem to have achieved an understanding.
Thank you very much for such a useful feature.

I think ubuntu-location-service-bin is not properly installed.

Just some questions. I see the following packages upgraded:

biometryd-bin
libbiometry1
qml-module-biometryd

Why do we need biometry stuff?

This ones were downgraded:

libubuntu-location-service3
qtubuntu-sensors
ubuntu-location-service-bin
unity8 unity8-common
unity8-private unity8-schemas

@mardy you mentioned Lorimi, but I still see unity. Is it all right? I understood this change was for xenial devices.
I hope I do not miss anything with the downgrade.

Wow! How did I miss this feature? I have seen the last post and realize that it was available two years ago.
Well, BQ E4.5 OTA 25. I have just installed it, but I am not very confident it will work. I get some errors that make me suspect:

ubuntu-location-service-bin#####]
W: No sandbox user '_apt' on the system, can not drop privileges
E: Sub-process /usr/bin/dpkg returned an error code (1)
ERROR:ubports-qa:Failed to run 'apt full-upgrade'. See the output above for details.
mount: / is busy
WARNING:ubports-qa:Failed to remount root filesystem read-only.
WARNING:ubports-qa:Please consider rebooting your device.

I have rebooted the phone. This weelend I will test the background data adquisition.

Does not sudo nano /etc/deviceinfo/devices/halium.yaml work?
Or using chmod does not help?

@Daryl There was an issue some time ago with OTA-25 and BQ devices. The behaviour was similar to what you described. The solution was to press power button and volume - together for up to 15 seconds. Maybe you have to retry a couple of times.

If that does not help, you can double check the files you used because be aware that there are two BQ Aquarius M10, HD and FHD.

Well, actually I had not used "Pictures" but the translation to my language. It seems that for saving in the SD card, "Pictures" is mandatory.
Maybe I am wrong but at least now I can save wherever I want to.

I found that the file ~/.config/user-dirs.dirs contains the default folders. So I edited it and restored the missing default home folders, e.g., XDG_PICTURES_DIR="$HOME/" to XDG_PICTURES_DIR="$HOME/Pictures".
Now I can save the photos in the device. The problem with the read only SD card persists. I have tried with a brand new SD card with no luck.
