Samsung Galaxy A12: A12 Screen wont turn on but it vibrates

Thu, 05 Mar 2026 08:16:24 -0700

My phone screen had recently broken so I purchased a replacement screen and had to take out and put back the entire phone (as I mistakenly got one without the frame) after it did turn on and was working, however, I noticed that the selfie camera was blurry so opened it up again to investigate, after that, I put the covers back and now it won't turn on, however, I can feel very often vibrations upon holding the power button. I have already tried to do resets, hold down the volume buttons, etc. Any help will be greatly appreciated

Samsung Galaxy A12: Why is my screen still black?

Sat, 03 Jan 2026 16:10:00 -0700

After cracking my A12 cell phone, the phone's screen would sometimes go black while using it. However I could still hear noises coming from it. For example, I would be watching a video and the screen would suddenly go black. I could still hear the video, but I couldn't see the screen anymore. I tried holding the bottom volume button and power button for 10 seconds, but nothing's showing up on screen. I also held the top volume button and power button too and it failed to work. My phone is still vibrating, so I know it's on especially when the alarm is on. However nothing is showing up at all now.

After replacing the screen, the screen wasn't black, but the problem was the same as before. The screen turned on, but it still went off when viewing a video or browsing a website. I noticed that when I tapped the bottom half, it instantly went black. What could be be the problem?

I also want to note that it currently won't even show up the logo or anything else anymore currently. Any help would be appreciated.

Samsung Galaxy A12: Phone won't start after the "yellow triangle" on the charge screen

Tue, 02 Dec 2025 02:13:39 -0700

Hi! So I've dropped my Samsung Galaxy A12 into a pool recently, turned it off immediately and dissasembled it and left it to dry for 48 hours. After that I put it back together and plugged it in for charging and the screen with battery percentage appeared with a yellow triangle under it, so I unplugged it and tried turning it on and it doesnt seem to work at all anymore. Nothing happens when I plug it in or when I hold the power button. Is it completely dead now or is there something I can do? Thanks
