Just because that seemed working well under 16.04 doesn't mean the android firmware was the good one and you shouldn't install recommanded required one.
Plus, it is recommanded to full install focal from ubports installer, not updating from xenial as it can lead to issues for now.
Last, Note 7 Pro is not already in supported focal device list (toggle filter to see focal devices in device list), so, knowing Focal is under heavy dev, and not fully stable on supported devices, don't expect it working well on yours.
Anyway, try to contact port contributor if you want to help improve port, you can find him on violet device page.
I got the same trouble with mi a2. First let inside one sim and reboot.
J'ai eu le même probleme. Je n'ai laissé qu'une seule carte sim et j'ai redemarré. J'ai eu internet de suite, mais les mms,ça a été plus long...j'ai rechargé plusieurs fois les mms avant de pouvoir les telecharger et sur une periode de 48h
@ckrnkfrnchmn There are q variety of bluetooth devices in different phones, requiring different settings that work out better for some.amd not for others.
Unless the user has some Linux experience with tinkering with bluetooth, to troubleshoot the issue or even discover a workaround, there is not much that can be done, other than filing an issue in the port issue tracker, and wait for the porter(s) to look into it.
Solved : It was indeed the network parameter of my mobile operator! I tried with another operator and it worked! Mobile data, MMS and mobile access point. Screenshots of the changes made to put back the correct settings. I also inserted Waydroid to find the applications I use: It also works. Thanks for the tracks.![alt text](photo_2022-05-19_12-12-50.jpg image url)photo_2022-05-19_11-40-32.jpg photo_2022-05-19_12-12-58.jpg
@ahmed_samy I recently also switched a phone with similar specs (32GB+3GB RAM, Nokia 6.1 in this case) from the official OS it came with when I bought it to LineageOS. The final update they gave the phone was based on Android 10, the last security update was in early 2021. With the latest available Lineage OS it is now based on Android 11 and there are weekly updates to install. It feels like it runs more smooth and is very well usable again. If there was a UT port for this one, I would obviously advertise that one here 🙂 , but LOS in this case is also a nice way to keep that "old" phone working well.
Lubuntu went downhill when they changed the desktop environment from LXDE to LXQt. Due to it being lightweight, it is missing a lot of dependencies that are in Ubuntu. I used it a lot on low powered PC's, it was a really good 32bit OS.
If you have a USB stick you can use that as Lakotaubp said and you don't have to install it, you can use the spare part of the USB stick as storage/persistence.
Here are some notes on my experience, and the community posts, especially Stanwood's were really helpful.
