I know people doesn't like Redmi/Xiaomi, but man what a punch for the money, and "malware" have been inexistant up until very lately (deep malware are everywhere). I bought a (the FX) file explorer for like 5€, there is a totally ok free version too and that's the only thing I needed to have a nice experience (no pub, I know everything is probably tracked like on all phones).
Got the redmi note (pro?) 2 shipped from alibaba.com a long time ago for < 100€, then the 5, 7 etc.
Greatest value for sure, they all still work except the 5 that I went swimming with, I cracked the screen on the 7, ...
The older ones also had swappable batteries (3000 mAh too!) and SD card slot when the concurrences had like 32GB for OS + everything else.
I'm not a fanboi but my 4 year old phone for 250€ has 6GB RAM & 128 GB storage...
