Some years ago, Google which bought Android destroyed the possibility to write to the external SD card and access is over USB from a PC.
We are currently evaluating how to solve this problem. We can buy a Google Pixel 3a phone, where Techut flashes UBports on it:
and flash PostmarkedOS on it.
Then, we have Google Pixel 3a phone, which is still worth to buy in 2023:
Then, we should be able to write to the external SD card again, and access the phone from a Linux PC over a router from a Linux PC.
Google destroyed options which where attractive for us personally.
We could solve the problem temporarily with a Google Cast HDMI stick to connect our phone to a HDMI monitor, and a Bluetooth keyboard and a mouse, which was a very unsatisfying solution.
Now, we can test the described procedure to see if it works with the Google Pixel 3a.
Google profits from all these steps in one or in the other way.
But we where completely happy with the Android phone we had, before Google started to modifiy it for it s own needs.
We are trying to find solutions, which are attractive for costumers, and not only for big companies like Google, and promote those as much as we can.
Don t invest to much time in Google phones. Maybe Google is already working on a solution how to make it difficult to unlock the bootloader, so that it is difficult to flash a new OS on it, how it is with Xiaomi phones aleady.
