Samsung Galaxy A51: Phone has a black screen only

Sun, 03 Aug 2025 05:45:33 -0700

The phone still works. I was able to tell by hearing the sound whenever I charge it. I was also able to tell that the phone still works by calling it with another phone since the phone with the black screen was ringing. I was also able to tell that it was still working by feeling the vibrations whenever I enter a number on the lock screen (When it asks for the password of the phone). Another reason why it is still working is because the alarms are still going off. I was also still able to connect my bluetooth earphones to the phone. I already tried restarting my phone, but what I don’t get is that the boot up logo (The Samsung logo) shows on the screen. After the boot up screen, the screen remains black. Is there a fix to this?

Samsung Galaxy A51: How to remove demo/retailer mode on Samsung A52 5G

Sun, 02 Mar 2025 06:12:23 -0700

There was no open for the device Samsung A52 G so I just put A51 as the closest to it, anyways got a phone off eBay because I was recently mugged and need a phone for most of my school work and I’m tight on money so I got the cheapest off eBay until I make enough for a new one and the demo/retail mode is still on. I thought I would be able to get rid of demo mode on Samsung just like I did with an Apple iPhone before but Samsung is harder to bypass on removing the demo mode. I have tried many methods and 1 is by going to the settings to reset and factory reset there but it’s grayed out and I can’t tap on it. 2 I did a hard reset doing the volume up/power button to factory reset but nothing happened, the phone still turns on normally without showing the factory reset page as it did on the videos I watched. 3 I made a Samsung account to go into the find my device phone on the demo phone to erase data but it opens a new website saying “500 error UNAUTHORIZED EXTERNAL”. I’m stuck on what my options are and I don’t want to waste money on some app that will most likely not even help in removing the demo cause I’m tight on money and need this device for my school work at the moment TIA

I was able to disable demo mode

Samsung Galaxy A51: Samsung Galaxy A51 stuck on charging icon (lightning bolt)

Fri, 01 Aug 2025 22:00:58 -0700

I have a Samsung Galaxy A51 which is stuck on the charging icon (lightning bolt). It shows no battery percentage. I tried replacing the battery and charging port but the problem remains the same. There is no liquid damage inside the device. Is there something I haven't thought off? Or is it a main board issue? I also tried force restarting the device with the volume - and power button

Samsung Galaxy A51: Short circuited motherboard on an A51 5G

Fri, 11 Nov 2022 08:52:27 -0700

Hi,

I'm desperate.

My Samsung A51 5G phone suddenly overheated massively and stopped working. Took it to a phone repair shop, where the guys worked on it for almost two hours, and gave the diagnosis: the motherboard is short circuited, and they don't have the equipment nor the competence to fix it. They told me that in our country, probably no one has. So my question is: where to find a person with the micro soldering equipment and skills to repair my phone? Quick googling didn't give me any answers.

I had backups for everything else, except for the Samsung Voice Recorder app. And that app has data so valuable to me that I'm willing to give a kidney to have that it recovered.

Samsung Galaxy A51: Fully functional display, but only for Samsung boot screen

Thu, 03 Aug 2023 14:20:37 -0700

Why would a Samsung Galaxy A51 be fully functional, but display absolutely nothing on the screen EXCEPT for the startup logo, recovery menu and the charging animation when the phone is switched off?

Got someone's phone where the display stopped working a few months ago, except for the three cases as mentioned above. They factory resetted it at some company.

Went through the painful process of switching on TalkBack and doing the startup wizard, switching on USB debugging in settings, then connecting the command line tool "scrcpy" and being able to fully view the screen on my Macbook.

Now how would I go about restoring this phone's display on its own, rather than just operating it through my Macbook, given that the display works during the very start of the boot cycle as mentioned above?

Thanks!

Samsung Galaxy A51: Spot of pink and blue color spreading from corner of screen

Sun, 02 Jul 2023 02:18:58 -0700

I don't remember exactly when the color appeared but I know I've dropped the phone a few times. The color started as a very small pink blot. Over time, the color deepened to deep blue and spread out with pink edges. I thought it would stay at the corner but it is slowly spreading and I'm concerned that it would soon start to seriously affect visibility.

Where I live, repair parts are hard to come by. A friend with an A52 had to pay an exorbitant amount to change their screen in order to fix a black screen of death issue it had and I'm worried I'll have to pay that to change my screen. Does this sound like a screen problem? Is there any way I can keep the spot from spreading more?

Good Evening!

I replaced the mobile screen with a new one and when I turned it on it was stuck in the charging state as if it had run out of battery and the device was closed. When I pressed the power button the device turned off and the same problem occurred. Do you have any idea what could have happened?

Samsung Galaxy A51: Not powering on or charge symbol

Tue, 09 Apr 2024 18:36:08 -0700

Hi.

I dropped my Samsung A51 cracking the screen in bottom corner. The crack spread across so I decided to replace the screen. Bought a screen and shell assembly and new battery. Transferred motherboard, charging board and battery to new shell. Put back together and doesn’t power on nor am I getting the charging symbol. I have tried the hold buttons down power on thing, but still no joy. It does do a small vibrate. Then nothing. Any suggestions please.

Many thanks,
