S9 Stuck In Bootloop Does Not Charge

What needs to be done if Galaxy S9 screen turns black after accidental drop

One of the common reasons why a phone’s touchscreen fail is accidental drop or any form of physical damage. In this short troubleshooting post, we answer a common question posed by a lot of #GalaxyS9 owners — what to do if touchscreen is no longer working. We hope you’ll find this post helpful.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: Galaxy S9 screen turns black after accidental drop

Hello! I feel like I sifted through the forum fairly well, but perhaps we can attack my issue on a step by step basis to see if there’s any route I could take you might recommend. At first, my touchscreen didn’t work on my S9 after dropping my phone, but the screen showed up just fine. Now, the screen doesn’t show up either (completely black), but the sound works when I press the volume buttons up and down. I just tried holding the volume up, power button, and home button to factory reset but nothing appeared on the screen and now I can’t see my phone responding to anything (not sure if it’s just off in a way I can’t work with, or what). All help is appreciated! No idea what my phone version is so I just put Oreo. — Christian

Solution: Hi Christian. First off, we want to emphasize the fact that your phone has been physically damaged. To what extent we don’t know but most probably, the screen assembly is toast. Dropping a phone or any electronic device may result to hardware malfunction, failure, or both. It also can lead to immediate, clear problems, or, in some cases, to problems that need time to develop. Drops or unnecessary blunt force trauma can potentially break components or even the motherboard. Some devices may work fine after you drop them while others may immediately show serious hardware troubles.

Secondly, your phone must still be working since you can still hear it make a sound when pressing the volume rocker. This means the issue is most probably with the screen assembly only. The screen assembly has three major parts — digitizer, monitor/LCD, and digitizer flex cable. The monitor or LCD is the part of the screen that displays the images that you see. Think of it as the screen of your laptop where you watch photos, videos, etc. The digitizer is a thin layer of transparent sensor that registers your taps and touches so the operating syste can translate them into computer-readable commands. Even if the monitor is working (displays images correctly), that doesn’t mean the digitizer works as well. If you can still see the things you’re supposed to see on the screen but the phone is unresponsive when you tap it, that’s because the digitizer has stopped working. The signals from the digitizer are transmitted to the motherboard via the flex cable. These three components work together in order to allow you interact with your device. If one of them dies, you’re out of luck. What happened to your device after the drop was that the digitizer stopped entirely, making it appear that your phone has become unresponsive. Then, after some time, the monitor also gave up, causing the current black screen situation.

So, as a final note, you clearly have a hardware problem. The only angle of attack that you can try right now is repair. Contact Samsung and schedule a repair appointment. If you’re lucky and the damage is only limited to the screen assembly, you’ll only be paying for the screen replacement. Yes, you’ll have to pay for the screen replacement even if your phone is still under warranty. Customer misuse such as accidentally dropping your S9 is not covered by Samsung warranty.

Problem #2: Galaxy S9 won’t stay powered on unless connected to charger, stuck in boot loop

My phone only turns on when its charging but if not it turns off and it also goes halfway from turning on.What happened was I dropped it a few times by waist height but after this one drop it still works but when i came back to use it stopped working like it won’t turn on.So then i went home thinking that its only dead but i didn’t know that my phone had a boot loop and another problem that it wont turn unless it’s charge.I got a bad temper that day.So,then i banged it on a carpet a few times but after researching about my phone.That’s when i realized it wont work and my phone .Also when i banged it on the carpet a few times it started boot looping on the start of my phone but after a few months.I came back and started fixing it but it kind of works.It just that It turns on for one minute and starts turning off again and its still a boot loop and it still wont change the fact that it wont turn on unless its charged.Please help me to fix my phone in any ways and if you could can you please tell me any ways that does not cost any money or something that is affordable. — Althea

Solution: Hi Althea. Like what we tell Christian above, the best thing that you can do right now is to get professional help, preferably from Samsung. Boot loop issue started to occur after the device was dropped and damaged so there might be an issue with its motherboard or battery or both. This may also be the main reason why your S9 refuses to stay on when it’s not connected to a charger. We’ve already seen a lot of same and similar cases in the past so we’re positive your problem can only be fixed by repair.

S9 Battery Drains Quickly

Problem: Hi, My Galaxy S9 has recently started to have issues with the battery, a few days it seems before the last update,  so I thought it might have been an app download that caused it. After uninstalling recent apps (and other little used ones) the issue continued, so then I thought it might be a faulty battery. The phone battery would normally run it for a couple of days with light use, but since the problem started, it drains almost completely in less than half that, the back getting very hot to boot, so worrying about an exploding phone I went to a service center and got them to replace the battery, as you know, this is not an easy task with the S9, as the glass back is glued on! Hoping that this would solve the problem, I was disappointed when it didn’t, so am looking for any other help you might be able to shed on the matter. I am not a heavy phone user, mostly calls, text, photos, notes and the odd sat nav trip, had it around a few weeks and been delighted so far, best phone/camera I’ve ever had, but this is crippling it! Have already tried clearing the system cache, that didn’t work either!

Solution: The best thing that you can do right now is to backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs. If it does then the phone might have some faulty component that is causing this problem. You need to bring this to a service center and have it checked.

S9 Stuck In Bootloop Does Not Charge

Problem: My S9 has been doing this on and off for a few weeks but never this bad. It happens especially when i have to restart my phone. it will come up with the ‘Samsung Galaxy S9’ and then start typing out the ‘SAMSUNG’ word and then jam and do it all over again. sometimes for 10 minutes, sometimes longer. my phone also gets very hot but it eventually comes on after some time. This time i haven’t been so lucky. My phones battery died and when i went to plug it in to charge it just shows the lightning bolt but doesn’t charge, when i try do the reboot which is when i hold down the power button, the home button and the volume DOWN button a green screen appears asking if i want to restart (volume DOWN) or do an OS thing (volume UP). one this worked a while ago but now it wont. and not it wont even charge.

Related Problem: The phone is stuck in a boot loop. The screen is always on, and displays the Samsung Galaxy S9 powered by android android screen, and every once in a while it flashes to black for a few seconds, then continues attempting to boot. The LED indicator is on, and blue except for when the screen turns black, when it flashes to green briefly. No error code is given at any time, and prior to the issues I was playing on an emulator and PUBG mobile.

Solution: The first thing that you will need to do in this case is to make sure that the battery of the phone has sufficient charge since you won’t be able to do any troubleshooting if the phone is off. Follow the steps listed below to charge the phone.

  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris stuck in this port.
  • Charge the phone for at least 20 minutes using its wall charger.
  • In case the phone does not charge then try using a different charging cord and wall charger. You should also test if the phone can charge from a computer USB port. If you have a wireless charger then you can try to use this as well to charge the phone.

Once the phone charges then turn on the device by pressing and holding both power and volume down buttons for at least 10 seconds.

If the phone is still stuck in the boot loop issue then you should start the phone in recovery mode then wipe the cache partition of the device. Follow this up with a factory reset. Take note that this will erase your phone data.

If the above steps fails to fix the problem then you will need to bring the phone to a service center and have it checked.
