screen no no longer works after battery replacement

HI there, I recently bought a battery from Ifixit for my note 10 plus.
i did the battery replacement and the device was perfect for about 3 hours. then all of a sudden the finger print scanner stopped working, i did a restart, the phone came up but the scanner was still not working. i tried doing another restart a few mins later after which i saw the Samsung logo flash as per usual but that was the last thing i saw on the screen, the display is fully black but the phone still works. i went back through the steps making sure ididnt miss anything ( as i said before the phone working perfectly after the battery swap for a few hours)

I can't believe this exact same thing just happened to me today. I replaced the battery and everything was working fine, so the fingerprint scanner start to stop working, but the fix was simple, I just needed to clear cache from biometric.app in settings and it worked again just fine. Today, I wake up with the alarm from my phone, but the screen wasn't working and I don't know what to do.

@guisb wow, really sorry to hear that bro... ended up carrying to a repair shop the other day. havent had a feedback about it yet.

but i am wondering if this could be intentional on Samsung's part.

@shaundavis They told me that the screen is probably dead, that possibly could had break when the battery was replaced, but they said it that wasn't sure about where the problem in the screen was. Why it stopped working after the same exact way it stopped working your phone? Idk, kinda sus, the price to change an amoled screen is exorbitant, i will buy a new phone, and I don't know if it will be Samsung ever again.

I have little experience with Samsung phones, but here are some things to try:

  • Reseat the connector
  • If you still have the old battery unplug (but don't remove) the new one and plug the old one in and just set it on top of the new one then try to power the phone on
  • Check for damaged pins on the female and male screen connectors
  • Check for a damaged screen

You did say it worked for a little, and the Samsung logo appears so I'm thinking maybe some anti-repair method triggered or something with the software could be messed up. Maybe try booting in to safe mode using the following steps:

  1. Turn off the device.
  2. Turn it on by pressing and holding the power button.
  3. Once the Samsung logo appears, immediately release the power button and then press and hold the volume down button.
  4. Continue holding the volume down button until the device finishes restarting.
  5. Safe mode will be displayed in the bottom left corner of the screen. In Safe Mode, only the pre-installed apps will be available. This mode can help determine if any third-party apps, or viruses are causing the issue you are encountering on your device, if it boots into the OS I have heard Samsung has a "secret" debugging menu but I don't know how to get to it

If you find anything but don't know what to do comment on this, or email me (tcolton721@outlook.com) and I can do more research for you. Good luck!

How did you remove the old battery? As the screen is under the battery you could of damaged the screen taking the old battery out.

完成的

Definitely anti-repair block, after my battery went to 0%, i recharged again and the screen worked, even if the technician told that the screen was dead, that's super shady, I hope my smartphone continue to work, but I think that anti-repair block will be triggered again, unfortunately

After talking back to the ifixit support they blame the broken screen on an installation error caused by me.
They DO NOT explain, why the screen was working fine for 24h, the DO NOT explain what the "installation error" could have been.
Overall i wouldnt try to swap the battery.

You still haven't said how you removed the old battery. If you used something to pry it up then you could of put too much force on the back of the screen causing it to start to fail. Samsung batteries are a nightmare to remove. I use a heat mat and alcohol to remove them.

i feel like this was deliberate so we cant repair the device. its crazy that soo many people bought from ifixit and have the exact same issue lol

Guys, I dont know why or how, the phone started working again. I turned it on yesterday and it seem to work fine.

The only thing is, that I now have a slight green hue while displaying grayish content, This seems to be caused by the glue Samsung used in the display (google "gluegate" ...its a thing).

Soooo I think I know what the problem is / was:

I think the alcohol i used to loosen the battery caused the problem. Maybe something got stuck or loosend something inside the display which cured again over time.
