Could I easily tell if the screen on the Motorola G7 Play is cracked especially when looking at a completely white image, and after pressing on the screen with my thumbs trying to get the case off the device?
You should be able to see a screen crack by simply inspecting the screen closely.
Don't you have another account that you're using to ask many of the same questions about the Moto G7 Play? Is there a reason you're posting with a different one?
