Hello, what is screen assembly? Will the display effect of the mobile phone be the same as the original one?

Nothing. The screen component is a combination of a touch screen and a display screen. If you change the screen component on one side, the effect will definitely be poor. After the original is soaked in water, it usually takes 7 days to cut off the power supply, disassemble the machine, wipe it, dry it in the shade and dry it naturally, then assemble it and turn it on. If these steps are done step by step, the damaged keys may be individual keys, or there may be some circular light and shade changes on the screen. If it doesn't light up, the water vapor in the mobile phone will run everywhere. If it is broken, I don't know where it is, and some things can't be measured. It's been fixed. It's nothing serious. Do it as soon as possible.
