I used Simple Mobile Tools apps on my GrapheneOS phone and I really liked them. I bought an iPhone recently because I wanted a phone with many years of security updates. I miss Android and F-Droid a lot. I wouldn’t buy this phone as I don’t want to throw it in the trash only after 2 years or so.
I would buy this right now if it shipped to the US.
Would probably err on the side of going for an old Pixel or OnePlus instead and flashing this on it instead; would be a faster device for less money and the same result
