Problem 1: Accidentally dropped Galaxy S7 black screen issue, won’t boot up normally

My Galaxy S7 fell and after a while it started acting weird. I tried to reboot and now it reboots alone after maybe a minute but it seems like he doesn’t really reboot. If I open an app and it reboots after he turns up the app is still open in the latest apps. Moreover, keyboard doesn’t work, pressing long on home key to get to Google doesn’t work, and sometimes even the background picture is all black. After one time I open the phone with a pattern the handprint is supposed to work but it doesn’t.. please help. — Adi

Solution: Hi Adi. Your phone was dropped. That’s an obvious reason why your phone is now having all these problems. The drop must be bad that it damaged the motherboard or multiple components at once. We don’t know what exactly do you expect but unfortunately, we have to tell you that there’s nothing much that we can do to fix these problems. The phone is clearly suffering from hardware malfunction so stop looking for software solutions and start finding a way to have it repaired or replaced. There’s no amount of reboots and software modifications that you can do to, say, fix a shattered screen, or motherboard. Unless you have the expertise to diagnose Galaxy S7 hardware issues, repair at your level is definitely out of the question. That more than one unrelated function are currently not working is a clear indication of a possible motherboard malfunction.

If you can access Samsung service center, bring the phone there so a trained technician can assess the hardware and advise you whether it can be repaired, or if the unit needs a replacement. Since dropping your device constitutes user misuse, Samsung will definitely declare the warranty void, even if the phone is currently under warranty at this time. Be sure to prepare a repair fee before sending the phone in.

Of course you can bring the device to an independent service center but we strongly recommend that you try Samsung first since you’ll most likely pay more or less amount to have the phone fixed.

Problem 2: Galaxy S7 edge stuck in bootloop after upgrading to Android Nougat

I have updated my Galaxy S7 edge with the recent Android update, the Nougat 7, after several days, my phone keeps restarting and worst, it wont turn on until the battery is drained. So I downloaded the firmware and flash it with Odin 3, still with Nougat 7 firmware with the correct model.

I think i have done with correct procedures but now, my phone still restarts.. 🙁 so what wouldd be the most right thing to do now before going to a technician? Should i flash it with the old firmware again? Thanks in advance. — Kristinetaberna

Solution: Hi Kristinetaberna. Try to reflash the bootloader using the original firmware file for this model and see if that will fix it. Flashing a bootloader follows a slightly similar process as flashing the firmware. Below are the sample steps (exact steps may be different for your particular phone model):

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the Device Added status and its ID:COM box has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

If flashing the bootloader won’t work, consider flashing the original firmware again. If that also fails, you’re doomed; have the phone replaced.

Problem 3: Three Galaxy S7 devices keep freezing, restarting on their own, replacement Galaxy S7 showing the same problem as the first

My device slows down and freezes to the point where it is unusable and I have to force restart it at least three times a day. I’ve brought my phone into verizon and I’ve even had it replaced (twice) and it still continues to be an issue. Have done the factory reset, cleared cache etc. I have no idea what else to do and any advice would be appreciated. James

Solution: Hi James. If you’re already using your third Galaxy S7 and the issue still remains, that’s a telltale sign that it’s not a device problem. Most probably, it’s how you take care of your device or the quality of apps you install. To see if either of them is the case, do another round of factory reset and let the phone run for a few days without any apps installed or files added (if you’re using an SD card, remove it). With the phone now running a fresh, known working software version, you should be able to know if our suspicion is right. Common sense should tell you that if the phone (after a factory reset and without apps) work normally, but becomes problematic again after you’ve reinstalled apps, you’re actually causing the issue yourself (by not screening your apps more strictly).

Yes, apps can cause problems (If you only know that now, then start thanking us for letting you know). Seriously, you should know that not every app that you can find in Play Store or in other sources are built perfectly. The truth is way different! The problem you’re having now must only be happening because one of the apps you install is problematic. In other words, you only have yourself to blame for it.

To fix the problem, you must invest a great amount of time and effort in identifying the cause. Since we have no idea which of your apps is buggy, you must install each individually, making sure to observe how the phone works after each installation. This can be a tedious process but it’s the only effective method of narrowing down the possible bad app/s.

Keep in mind that it’s possible a virus or malware is responsible for the problem as well. If you don’t have an antivirus app, make sure to install one first before attempting to re-install the rest of your apps. This will help, in some degree, in detecting potential bad apps. Not all antivirus apps can detect viruses though and some apps can disguise themselves as legitimate ones during the installation, but then transforms into malicious forms after some time. This is the main reason why antivirus apps can sometimes be a waste of storage space. Your first line of defense is therefore how you screen your apps. If you tend to install apps left and right, without checking the reputation of their sources or developers, it’s only a matter of time before you’ll compromise your system, or encounter problems like what’s happening now. When it comes to today’s computing, and yes that includes using your smartphone, which is a miniature computer, it’s good to have a suspicious mindset. Just because an app looks legit does not not really mean it is. Do some research and see how other users see the app by checking their reviews. Avoid installing apps outside of the Play Store. Try to stick to official apps as much as possible.

Finally, try to limit the number of apps you install. You don’t need to make your phone an app depository. Like in real life, keep it simple and save yourself some unnecessary trouble. The less apps you have, the less chances you have in encountering problems.

Problem 4: Galaxy S7 warranty issue, S7 Samsung Protection Plus

I read here that warranty won’t cover this issue. My phone is not even a year old, never been dropped, always in cover, so I don’t really get why it doesn’t get covered. Same issue happened 2 days ago and i followed these steps and phone started to work. it worked fine for 2 days and i pluged it in to charge. picked up the phone placed it in my pocket. when i got into the car to play some tunes phone was off. Battery was at 78 when this happened. HELP. — Olle

Solution: Hi Olle. We don’t work for Samsung so we can’t declare what a warranty for a specific device in a specific country covers. However, based on publicly available sources and with our historical interactions with them, there are some things that don’t change. Below is list of things that can void the standard manufacturer warranty for Samsung devices:

  • water damage
  • damage from handling like accidental drops
  • hardware tampering (like allowing non-Samsung certified technician to take the phone apart)
  • software tampering like rooting and flashing

In some cases, Samsung can waive some of the items above if you’re willing to way for an enhanced insurance like Samsung Protection Plus. Be sure to refer to the documentation that came with the device so you’ll know what kind of warranty you have in your phone. Alternatively, you can contact Samsung directly to see if you’ve forgotten the type of warranty you have in your device.
