I still use an unsupported 2018 Asus ZenFone Max (M1) ZB555KL X00PD with a broken screen. I’d like to change the screen.
Measures of the device: 156 x 77.5 x 10.6 mm (6.14 x 3.05 x 0.42 in).
Now, I don’t know if these are standard measurements for a certain set of smartphones (the ones that can be held and used with just one hand) or if any company can choose what size it uses for their devices, making finding a screen that fits incredibly more difficult.
The other question is, how difficult would it be to do it myself?
Most screen sellers will list by model. So you can punch that in and it will land you on the right one.
The hardest part will be taking the case apart without breaking anything. Screens are usually just flex ribbon cables.
