“I hope you mean SM-A528B/DS (a52sxq)”
I try to follow [HOWTO] Install /e/ on a Samsung smartphone with Windows easily) and when i look in Settings> System >Model number (as in I see only SM-A528B/DS.
" and adb shell = supplies the devices codename" : do i need to intall first adb on my laptop to find out if I have the right model?
And if I’ve got the wrong one, I don’t think the refurbished phone suppliers can make this distinction.
