First off, if your device is still a few days old, you are eligible for a replacement if the problem can’t be fixed by a technician. But it means that you have to go through the hassle of possibly lining up at the local store to have an appointment with a technician and wait for several minutes before being able to talk with another representative to give you the new unit. In a bid to save you from all that, I’ve outlined a troubleshooting procedure below to help you make your device work again…
Step 1: It might just be a system crash and a Forced Reboot is necessary
This is the first thing you should do. It’s easy and it’s safe. It’s an equivalent to the battery pull procedure for devices that have removable battery.
If it’s a system crash or a minor firmware or hardware glitch, then this procedure should fix it:
- Press and hold the Volume Down and Power keys together for 7 to 10 seconds or until the device reboots.
The device will perform the simulated battery disconnect if it’s done successfully and if it still has enough battery to power up its components.
Step 2: It might have ran out of battery, so put it on charge
If the first step failed, then it’s time plugged the phone in to charge even if you know the phone has enough battery left because you’re not just actually trying to replenish the battery, you’re also trying to find out how the phone reacts if it detects current flowing through its circuit.
Plug the charger in and leave it be for, at least, ten minutes; there should be enough battery to power it up if it indeed ran out of battery.
While it’s plugged in, try to see if the LED indicator lights up. It doesn’t matter what the color is as long as it’s lit up, the device should be ok.
Another thing you have to check is if the screen displays the usual charging icon. Powered on or off, the charging icon should be displayed on the screen when it’s connected to the power adapter and there’s current flowing.
If none of these indications show, then there’s something wrong with the phone. Proceed to the last step.
Step 3: If the phone charges fine, try booting it in safe mode
Assuming that the device showed all the charging signs when you plugged it in, it’s time you tried booting it in safe mode to temporarily disable all third-party apps and services that may have caused this problem. But before doing so, I want you to try to do the procedure in step 1.
- Press and hold the Power key.
- As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
- Continue holding the Volume Down button until the device finishes rebooting.
- You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.
Step 4: If the safe mode failed, try booting it in recovery mode
The purpose of this procedure is to know whether the phone is still capable of powering all its components up. In recovery mode, Android interface won’t be loaded during boot up but all hardware will be powered up. If the Galaxy S7 Edge can successfully boot up in that mode, then it’s more of a firmware issue than a hardware one.
Step 1: Press and then hold the Home and Volume UP keys, then press and hold the Power key.
NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
Step 2: When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
Step 3: When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
If the phone won’t respond after pressing and holding the Home, Volume Up and Power keys, then proceed to the last step.
Step 5: Get technical support or have the device replaced
You have no other option but to go to the store or your provider and have the device checked by the technician. If the tech can’t fix the problem, too, then you are going to received a brand-new replacement unit as long as you’re within the grace period (usually 15 days since date of purchase).
