Problem 1: What to do if Galaxy S6 won’t stay on after accidental drop

Hello. I recently dropped my Samsung Galaxy S6 and now I can’t get it to turn on. It was not rooted and I think it had Nougat installed but I am not 100% sure. Before I continue, keep in mind that my phone will not do anything unless it is plugged in. I tried everything below while my phone was connected to a power source. Once I unplug it, the phone turns off. When I plug my phone in it will try to start up after a few seconds, displaying the “SAMSUNG Galaxy S6 powered by Android” screen. Then it will show the blue “Installing system update” screen for about half a second before turning black again and tries to start. This cycle will repeat indefinitely. I have the S6 so I can’t easily remove the battery.

I’ve tried holding the power button, holding the volume down and power button, holding the volume up, home, and power button, booting in recovery mode, and booting in safe mode but none of these have helped. The only thing that happens is the phone will no longer display the blue “Installing system update” screen. It will just show the “SAMSUNG Galaxy S6 powered by android” screen over and over. However, when I hold the volume down, home and power button, I’ll get the “Warning, A custom OS can cause critical problems etc.” and I am presented with “Volume up: Continue, Volume down: Cancel (restart phone), Home Button: Show barcode”.  I haven’t tried pressing continue but when I press volume down it will go back to looping through the startup process. Pressing the home key will display a barcode along with the MEID. If I press anything else after that it will go to a “Downloading… Do not turn off target” screen with “ODIN MODE” in the top left corner along with other information.

I’ve left it on this downloading screen for about 45 minutes and it doesn’t do anything. I have to pull the charger out and the phone will turn off. Once I plug it back in it will continue to keep trying to start.

If you have any questions about the phone feel free to ask them. Any help would be greatly appreciated. — Harrison Hirsch

Solution: Hi Harrison. Accidentally dropping a smartphone can result to two things — either it works afterwards or not. It’s one of the uncontrollable situations a user can experience.

No software solutions for hardware malfunction

First of all, we want to make one thing clear here. A hardware problem can’t be fixed by a software solution. A physically broken component can’t be solved by reverting settings to their defaults, or by flashing stock firmware via Download Mode. If, for instance, if the power management IC, which is a critical component in ensuring that there’s a stable source of energy going to the motherboard, was damaged after the drop, there’s no amount of software modifications that you can do to fix it. The phone has to be opened up and that particular part has be to either repaired or replaced in order for the device to continue working normally. The same is true for any other component that may be damaged due to the unnecessary force during the drop.

Luck does not always work

Secondly, we don’t know the circumstances surrounding the accidental dropping of your device but if it hits the surface badly, a lot of things can go wrong at once. While most electronics today can survive a drop from a certain height, some may fail even when they only fell a few inches. Samsung and Apple tries to make their products as durable as possible but not one electronic device is fully immune to drops. The shock that comes during an accidental drop can only be minimized but not fully eliminated. Even some expensive hard external cases cannot fully protect a phone if it’s dropped badly. Sometimes, luck also plays a part in these situations.

Repair is necessary

The symptoms you mentioned above are consistent with a failing hardware. If your phone was working normally before you dropped it, that is, it would stay on even when it’s not plugged in, then it’s clearly suffering from hardware malfunction. hardware -wise, a Galaxy S6 is a complicated piece of equipment and only a trained technician can identify where the problem lies. In a lot of cases that’s similar to yours however, the common reasons for a situation like the one you’re experiencing now includes a damaged battery or busted power management IC. Any problem arising from malfunction of these two components needs opening the phone up and running some diagnostics. Other unknown hardware issues may also play a role and they too require a technician doing some hardware diagnostics. It is for this reason that we recommend that you send the device in for repair. Unless you are equipped to take the phone apart, run some diagnostics, and be able to replace the battery, we would advise againsts self-repair or do-it-yourself (DIY) repair.

Based in our experience, more problems are created by first timers doing DIY repairs than solutions. If you are 100% certain though that you can manage to open the phone up and has the necessary basic tools to do it, try checking the battery to see if replacing it will fix the issue. If you can, try to also see if you can replace the power management IC (if you can find an exact the same component) to see if the problem comes from there. If you don’t think you can do any of these things though, consider letting a professional do the job the job for you.

Problem 2: Galaxy S6 screen won’t unlock

Hi. I have a Samsung Galaxy S6. I have the fingerprint and lock screen enabled and after a reset, either the passcode isn’t working or I can’t remember it. I can access lots of the phone such as the top settings and such the Wi-Fi is on and the Bluetooth is on it’s getting notifications and says that things are running even though I haven’t been using it for a long time. the Samsung account has timed out and it needs to be signed in to Google but Google has located a couple times. I tried the adding the lock screen and then removing it, that didn’t work. it won’t turn off without the passcode and it doesn’t hard reset, it only goes into odin mode. It also has been trying to be reset several times and it won’t go into a Google remote for Recovery either. it just makes the time longer and longer each time it since you’re wrong. Please help. — Mesha

Solution: Hi Mesha. We don’t think we understand what you’re driving at here exactly but if you’re having trouble unlocking the screen, these steps below may help you:

Unlock your phone  using  Android Device Manager

This should be the first step that you must try, especially if you are signed in to your Google account in the phone. This method only works if you already registered your device with Android Device Manager. If it’s registered, you can then use ADM’s lock feature to reset the Google password using a computer. Below are the requirements in order for you to use ADM to unlock your S6:

 

  • phone must be turned on
  • phone must be signed in to your Google account
  • phone must be connected to wifi or mobile data
  • phone must be visible in Google Play
  • phone’s GPS or location must be turned on
  • phone’s Find My Device feature must be turned on
  • phone’s Allow remote lock and erase feature must be enabled

If any of these requirements is not met, there’s a chance that you won’t be able to use ADM to unlock your S6.

However, if everything is set, you can proceed to unlocking the device by doing the following:

  1. Go to the Android Device Manager from a computer.
  2. Find your device on the screen.
  3. Enable “Lock & Erase” feature.
  4. Follow the given steps on the page to lock your phone.
  5. Set a temporary password.
  6. Enter the temporary password on your S6.
  7. Create a new password.

Unlock your S6 using Samsung Find My Mobile

Samsung’s Find My Mobile is a remote service similar to Google’s ADM. In order for it to work, you must have registered your device in Find My Mobile website or service. And like ADM, it also requires some things. Below are the necessary things that must be met in order for you to use it:

  • phone’s Remote Controls feature must be on
  • Google location service must be on
  • phone must be connected to wifi or mobile data

If you’ve already registered your device to Samsung’s Find My Mobile service before and the rest of the requirements are met, you can then do the following to unlock your phone:

  1. In your computer, go to Samsung Find My Mobile website and sign in.
  2. If you have multiple devices registered, make sure to select the correct one in the upper left hand side of the screen.
  3. Click on the arrow icon to begin searching for your device.
  4. Once the service has located the device, scroll down the options on the right until you see Unlock My Device option.
  5. Click Unlock My Device.
  6. Enter your Samsung password.
  7. Click Unlock.

If the steps above won’t help in unlocking the screen at all, consider flashing the firmware back to stock. You can use Google to find good guides from other websites on how to do this job. Just be sure to use the correct guide and firmware version for your particular phone model. Be very careful when doing the flashing procedure as following an incorrect guide, using a wrong firmware version, or doing an incorrect step may lead to more serious and/or permanent software issue.

Problem 3: Galaxy S6 won’t hold a charge after it’s been dropped

I dropped my phone a few days back. Battery percentage was 55% before, and it wont turn on. It dropped to zero and it won’t work without the charger. After switching on and off a few times and charging it, it suddenly went again to 55%. I dropped it today and the height was less than 2 feet. Same thing happened , just this time it wont charge no matter what. It’s on zero percent and turns off as soon as i remove the power cable PLEASE HELP. — Noor UlHuda

Solution: Hi Noor. Your case may be exactly the same as that of Harrison’s above so kindly visit our suggestions for him. As mentioned above, a case like this may end up with a repair so if you’re going to do that, be sure to let Samsung handle it. If you don’t have a Samsung service center nearby though, consider letting an independent third party shop check and fix the problem.
