Yesterday i replaced a cracked screen for my customer's A53 that was not working since November of 2023 .

I found an OEM OLED Screen so i bought it replaced the old one .

After the repair was complete I turned the device on and ran the diagnostics where it passed all of them successfully, so I proceeded with gluing the back of the phone. I realized that the device lags quite a bit, so I suggested my client to proceed with factory settings because his mobile phone may have unwanted applications that make it slow. He took the device and proceeded to update the software and applications and noticed that the touch sometimes gets stuck, like when you try to browse your mobile phone with wet hands, something that is fixed by restarting the mobile phone, but it reappears after a while. It doesn't seem reasonable to me that the mobile phone is slow after a screen replacement, rather I believe that the mainboard flex is faulty and needs to be replaced. What is your opinion and what steps would you take in my position?

Received it from a friend, was able to turn it on and perform a factory reset, then was able to get to the main screen, did the screen test and it passed then the phone randomly turned off, so I plugged it in and let it charge (He hasn’t used it in like 2 months so I thought it just needed a fresh charge) after leaving it plugged in over night, it still will not show any life, I opened it up, no water damage and no physical damage anywhere to be found I also checked all of the connectors and they’re in excellent condition. Also no battery swelling or punctures. I have tried 8 different cables, and no dice, I’ve tried the soft reset, and a few other methods, pc won’t detect it, so I’m not sure how to go about. Any advice or anything of the sorts would be swell. Thank you.

I assumed the battery was damaged as I've read water and batteries don't like each other and even have a tendency to get hot like mine did. So I bought a new battery off the Amazon, I also bought a new charge port, and a new screen with housing. I have replaced all the parts.

Now when I plug in the charger the screen does nothing, as if the plug is not being detected. But I can feel some heat in the back when the port ribbon connects to the mobo, as if it may be charging? However when I try to boot the phone with the power button, the mobo section just gets incredibly hot and the screen does nothing. Very similar to when it was first in the wash.

The heat appears to be coming from the area of the board that has two silver metal blocks, on top of the area where the sim/sd card slide holder goes in.

Now, I'm not a solderer or a microtech, but I can follow a YouTube video as good as the next guy, and I've built PCs before, so I'm reasonably sure that I didn't damage anything during the parts replacement and that everything is in and connected to the right places. I'm really only trying to get the phone to boot long enough to back up the data, any help would be appreciated.

not too long ago we took in an almost unused A53 but it had a crack in the screen so we decided to replace the screen to make it mint again. after i tried replacing the screen with a new one the touch suddenly stopped working.

while looking around on the internet I am reading about complaints about it happening a lot with the ribbon cable, but i also replaced that (twice) and I also tried 3 different working screens(2 of them soft-oled and 1 service pack from samsung themselves)

is there anything I could still try or a common problem with this? I am having a hard time fixing this device and it feels like a waste to give up on it at this moment
