@keneda Well, the camera quality is overall quite bad :(. The fact my MX4 only has 16GB of storage doesn't improve things and I am also missing Waydroid (currently using PinePhone with Manjaro for that) because for reasons beyond my comprehension you can't live without iOS or Android apps in some countries :(. I would again need to replace the battery (I have done that at least 3 times since I had the phone already) as it is starting to feel like a PinePhone now not lasting for a reasonable time and I am still facing these crashes very often. And on top of that I expect Ubuntu 20.04 is not going to be available on MX4 either, albeit the kernel might be able to fullfil the requirements as it can also run Anbox.
I wanted to wait for some special new device, have been doing so for the past 2 years at least, but unfortunately there is still nothing that I would love and Redmi Note 9 Pro is still purchasable and seems to have quite decent support. So it caught my eye and persuaded me to try that one out :).
