I want to restore this old phone of mine that's just laying around, it still turns on but the screen flickers random colors at random times, so replacing the screen seems to at least return it to a functional state. But I also want to use this as a semi-normal daily driver. That's obviously not possible if at the slightest hint of water, this phone will permanently brick. So I wanted to ask if a screen replacement here is sufficient to get this back to a mostly normal usable phone? The metal frame was slightly scraped off in a fall.
