S7 Randomly Turns Off

Problem: This is the 4th times this has happened to my phone. It randomly turns off and I’ve successfully reset it (battery pull). And I had to wait until I charged it for a while before it would even do it successfully.  But this time, it’s a little different. My blue notification light is on. Not blinking, just on. And it has been on the charger for a while now. And pressing the volume down and power key is not working. Neither is the volume up, home and power.

Solution: Do you have a microSD card installed in your phone? If you do, try removing this as this could cause this kind of problem especially if the card has some corrupt sectors.  

If the issue persists or if you don’t have a microSD card installed then you should check if the phone can start in recovery mode. If you are able to access this mode then do the following troubleshooting steps listed below.

  • Wipe the cache partition of your phone.
  • Do a factory reset. Take note that this will erase your phone data.

If the issue persists at this point then you should bring your phone to a service center and have it checked.

S7 Restarts Constantly

Problem: Hey. I have problems with my Samsung s7 quite often. It will just shut itself off and restart constantly over and over then sometimes it just freezes for no reason and I have to hard reset to get it working again.

Solution: If your phone has a microSD card installed then try removing it then check if the issue still occurs. If the phone doesn’t have a microSD card and since you have already performed a factory reset then this might already be caused by an internal component that is failing to work. I recommend that you bring your phone to a service center and have it checked.

S7 Will Not Charge

Problem: my Galaxy S7 said that the charger was wet and will not charge until it is dry, however now it is dead. My phone was fine this morning and throughout the day it was never in contact with any liquid and it will not charge, when I plug the charger in, the phone responds with the charging symbol but then promptly goes away. And it continues to do so. When i take the charger out of the port, I check for liquid on it and there is none. Is there anyway you can tell me what is going on?

Solution: Try checking first if the charger that you are using is causing the problem by using a different one. Make sure to also use a different charging cord. Before charging the phone make sure to clean the charging cord using a can of compressed air. Make sure that any dirt or debris stuck in this port is removed.

If the issue persists then you should bring your phone to a service center and have it checked.

  1. My galaxy s7 randomly shuts off and doesn’t turn back on for days. I try charging it and it just had the lightning bolt instead of the percentage…

  2. I have the same issue as Lily. My phone’s battery (S7) has recently been draining more quickly than it was but also, the phone just shuts down when the charge gets to about 30% or thereabouts. When I plug in charger it shows 0% but charge level quickly rises (e.g. Gets back to 15% in under 5 mins). I’ve been uninstalling and disabling various apps but this doesn’t help. Have reset and cleared cache a couple of times.

  3. My galaxy s7 has been shutting off at 20% (the phone is not on power saving mode, BTW,) and when I plug it in to charge it shows it drained to 0%.
