@keneda I haven't had much luck with these despite having them installed. Either because I was doing something wrong or because I picked the wrong apps to try with. Fortunately I don't need these for the few apps that I have to use. https://github.com/microg/GmsCore/wiki/Implementation-Status

@keneda It's in the devices subforum so it's easy to guess he's talking about one of his phone :)) There are 5 phones (4 codenames) joyeuse, curtana, excalibur, gram.

Hello. First things first very sorry for the late reply. You probably bought another device or you found a way to use anbox/waydroid. I am still typing because i want to give some information for those who want to install Ubuntu Touch on their Redmi Note 9. Regarding your question, you don't need adb to install waydroid (anbox is long gone now and waydroid is much better) and you can install whatsapp easily inside waydroid. Just go to OpenStore and download waydroid helper. For other people who want to learn about this device, it is daily driveable. But there are bugs here and there. These are the list of bugs that i remember: Connecting the device to a pc doesn't work therefore no sideloading and no adb Brightness slider doesn't work correctly. You can get to the level of brightness that you want but it takes some work. Because brightness slider doesn't work, when you turn off or on your screen for a split second the brightness rises up. This isn't a problem on daylight but may cause small "flashes" on night. Camera notch isn't aligned with the black bar where wifi icons etc. are. Also, this device has rounded corners so you cannot see AM/PM fully. 5.This is not a bug but camera software is really bad. But it works. This is the most important bug. Power cycle isn't working correctly. For example, if i try to turn off the phone, it works for 7/10 of the time. In that 3/10 the phone reboots instead of shutting down. Same thing with rebooting. But holding down power button resets the whole phone so rebooting is not a problem. These are all the bugs. Some of you may find these bugs critical, some of you may not. Also remember: you can reset to stock miui with fastboot flashing. Just hold down volume down and power until you see fastboot and then using XiaomiFlash flash back to stock firmware.

@nitanmarcel said in Xiaomi redmi note 9S daily use: Also, remember that some apps don't need to have the app suspension disabled: Messaging apps that use Ubuntu Touch's notification system (E.G: TELEports). To be honest TELEports doesn't work very reliable on my phone so I am not sure if it's a good example ?! I miss more messages/notifications than I receive and the app beeing opened or closed doesn't seem to make a lot of difference... Damaged battery: Also, our phones have what I like to call "A lot of garbage" in the form of customized kernels, ROM ports, which might contributed to the damage the battery in the past if they we're configured incorrectly (E.G: Kernels that enable charging voltages that shouldn't be enabled on the phone, Kernels that overclocks the processor, graphic chip making the device use more power than usual, etc).* Another factor that might decrease the battery health are fake chargers, unofficial chargers, etc Sorry but that sounds like a bunch of nonsense... The only thing I can agree upon are these two : Kernels that enable charging voltages that shouldn't be enabled on the phone. fake chargers. The rest can be ignored!

@j-mackay93 You don't need the Sensor Status app for gps to work, but it may be handy for diagnosis of problems. Instead of setting the lock screen to never, which will drain the battery quickly, I suggest you prevent Unav suspension from UT Tweak Tool so that the screen locks when Unav is not in use. The same applies to OSM Scout Server if you want to use off line maps.
