Following various requests from people wanting to use the Redmi Note 7 with Ubuntu Touch, I would like to share my own experience of the features that are not yet fully functional on this device. (Status: OTA-16 stable)
My overall impression as a daily user is generally very good. The device is one of the best in terms of performance, stability and portability.
Here's the official statement of device usability:
Installation: I was fortunate enough to be able to purchase a device already running Ubuntu Touch. I know that many people experience installation difficulties, both in unlocking the bootloader, and in installing via the UBports Installer.
However, I can confirm that reinstalling Ubuntu Touch (when already installed) via the installer works perfectly.
Here are the non/partially functional items on my device:
Online charging: No charging indicator on the screen. But charging works anyway.
Offline charging: Not functional. Automatically starts in fastboot mode
Video recording: Does not work with the main camera (app camera freezes) but works with the front camera.
Pictures camera: Maximum resolution 13 MPX (9 MPX in 16/9 mode), while the camera has 48 MPX.
Only the bottom lens is functional.
Flash and zoom are working.
HDR mode does not work (application freezes)
Bluetooth: After switching on the Bluetooth, the device must be restarted for it to be active. Media transfer and music streaming work, but not calls to hands-free devices. Conversations are not redirected to the Bluetooth device.
Automatic brightness adjustment: Does not work, although the option can be checked in the settings.
Echo during phone conversations: Can be fixed at each startup by typing the following command in the terminal:
setprop persist.audio.fluence.voicecall false
Fingerprints unlock: Works, but makes UT buggy. Troubles to close apps. I recommend to leave a 4 digits pin code to unlock the device yet
The usage statistics on the home screen are not displayed.
SD card: Very occasionally my micro-sd is not recognized at startup. (256 GB) A simple reboot fixes the problem.
Notification Led: Not existing / Not working
Apps: The app "Music recognition" does not work (green microphone button remains inactive):
Unable to grant the microphone access through the web browser:
"IMoon" app does not store data from last session
Notch: Same as Vollaphone, the notch can hide the time display.
Not tested: Hotspot. ADB access. Anbox
Everything else works fine, almost no bugs. Good endurance. Very responsive GPS. Good battery life. SMS/MMS/calls/Wifi/Cellular data, ease of use, etc... are perfect
Of course this is only my own personal experience
I hope this feedback will be useful to those who are hesitating to take the plunge!
