I had many problems with Fastboot not working or displaying "press any key to shutdown". I find a solution here : https://forum.xda-developers.com/t/help-press-any-key-to-shutdown-in-fastboot.3816021/ In short plug a USB 2.0 Hub into your computer and then plug the phone in one of the hub USB 2.0 ports I finally succeeded in flashing my Mi A2 with the latest Android image available with MiFlash.

I haven't need to using banking in my phone. I don't need any special facilieties. I must have a send SMS, calls and simply browser. And od course battery time should be at least day. When i had a Nexus 5, it was using as my second driver phone, but it had broken. In Monday i installed UT on Xiaomi Mi A2, but I have a problem with short time on battery 🥲 UT is morę stable and comfortable OS than earlier. Only problem is baterry time. I must charge Three times on 24 hours, what is very non comfortable. I'm looking solve on this forum and I Hope I will find this I wants to UT stay my first daily driver OS on mobile

@embeddedmz And you don't even have the MX4... Battery on this device is never accurate

Hi. I resolve the problem in Android setting off the option 'Precisione della geolocalizzazione in google' ('google geolocation accuracy', my phone in in italian). Is there any way to set the same option in UT?

@domubpkm Thank you very much for the github link, "GreUms78" answer helped me to fix my issue : I changed the URL from mmsbouygues etc... to b2bouygtel.com

@embeddedmz If you reinstall in the box that says Ubuntu 16.04 Stable is a drop down and you can select the channel. However, just thinking, if you can access on the phone the app store, install UT Tweak tool and in there you have an option for scaling which may help.

@nero355 Do you think this one will work with Ubuntu Touch : https://www.amazon.fr/gp/product/B089FBGH2B/ref=ox_sc_act_title_1?smid=AXZ3JQ1GVFPIF&psc=1 Update : yes it works !

@bogotrax Since Shouko doesn't maintain this device from march on anymore it will hardly make any news, but i found out that bluetooth simply "doesn't like" when the cellular data is on. It only works when wifi is on and it needs a reboot after that. It is very annoying since waydroid" doesn't like" wifi which makes it impossible to for example listen to music when you are on your way with the mi a2. Anybody experiencing same or similar issues and searched for a solution already? My skills are limited but i like to learn about more terminal commands if that helps in my issue. Having cellular data on and no wifi, simply doesn't let the device find any other bluetooth devices. Rfkill shows no blocks and the bluetooth service is enabled. So there shouldn't be a reason that it doesn't work. Any other ideas on debugging the issue?

Host your own Cloud with NextCloud There are apps for it already too! See : https://open-store.io/?sort=relevance&search=nextcloud But IMHO any service that works fine with the browser is good enough and the less apps you need the better!

At first I tried by terminal the dépendency but it was the os. Even Gearboy color cant use of the controller option it has. Or it can be possible somehow?

@mkarpicki After installing a fresh Android 10 image, now I can boot TWRP. I finally succeeded in installing Ubuntu Touch thanks to the link you have posted. Thank you
