S7 Went Into Bootloop During System Update

Problem: My samsung galaxy s7 was undergoing a system update and went into a bootloop. Whenever the phone reaches 28%, the phone restarts and the process begins again (reaching 28% and restarting). A soft reset restarts the device but the boot loop continues. Safe mode won’t work/load, and I believe other processes like recovery mode won’t work.

Related Problem: Hi, I got just stuck with a software update for my s7 device. It has done the initialising system update but now it is in loop from restart and ‘installing applications’. It doesn’t install anything and after a minute it restarts. Thank you for your help!

Solution: The first thing that you need to do in this case is to remove the microSD card ( if you installed one) then connect the phone to its charger. While connected to the charger try turning the phone off then on again. If it is still stuck in a bootloop then disconnect it from the charger and try to access the recovery mode. If you are able to access this mode then you have to do a factory reset from here. Take note that the reset will erase your phone data.

If the above steps fails to fix the problem then you should consider flashing an updated firmware file to your phone using Odin.  You can get the firmware file as well as the instructions on how to flash your phone from the Sammobile website.

S7 Not Charging After Getting Wet

Problem: So i gave my little brother my s7 a month ago and he started having issues after he went to a creek. First he said he dropped it in a puddle and then took it home it worked fine then the screen shut off and did not turn on for another 2 days. Then it turns back on but it wont charge at all with different cord or anything. Still need to try wireless charging but just wanted to know what you guys think it could be.

Solution: Although the S7 has a waterproofing feature the phone can still suffer from water damage especially if the seals have become weak thus causing water to enter the device. In this particular case the phone was dropped in water then the problem started. There’s a big possibility that the problem is caused by water entering the phone.

What you should do in this particular case is to make sure that the phone is dry and free from any moisture by placing the device in a bag of rice for at least 48 hours. . The rice will absorb the moisture inside the phone. Once this is done proceed with cleaning the charging port of the phone using a can of compressed air. Make sure that any dirt or debris stuck in this port has been removed.

Try charging your phone. If it doesn’t charge even when you try to use different charging cords and wall chargers then it’s possible that some hardware component has been damaged by the water. I recommend that you bring your phone to a service center and have it checked if this is the case.

S7 Randomly Stopped Charging

Problem: My samsung galaxy s7 randomly stopped charging through last night I put it on charge before I went to sleep and when I woke up it was completely dead and won’t charge i’ve tried 5/6 different chargers

Solution: The first thing that you should do in this case is to perform a simulated battery pull. This is done by pressing and holding both power and volume down buttons for at least 10 seconds. Your phone should reboot after this. If your phone does not turn on then proceed with the troubleshooting steps listed below.

  • Clean the charging port of your phone making sure that any dirt or debris that is stuck in the port is removed.
  • Try charging your phone using a different charging cord.
  • Try using a different wall charger when charging your phone.
  • Check if your phone can charge from a computer USB port. If it charges this way then one of the pins of the charging port could be damaged. You need to have this checked at a service center.

If after performing the steps listed above the phone will still not charge or turn on then you should bring your phone to a service center and have it checked.

S7 Moisture Detected Error

Problem: Phone says moisture detected when i plug it.i did drop in toilet 2 weeks ago…does not show age y single time i plug it. When it does. It won’t charge until i take a blow dryer to it.i couldn’t find the sticker in sd slot to check if there is water damage…

Solution: What you will want to do first in this case is to make sure that the charging port of the phone is dry. The best way to do this is to use a vacuum to take out any moisture that could be present in this port. A hair dryer will also work as most people use this to dry the port. Once this is done and you still get the same error message the next thing that you should do is to try to use a different charging cord when charging the phone as the problem could be caused by the cord that you are using.

One last troubleshooting step that you should consider doing is a factory reset. This allows you to check if a software glitch is causing this problem.

If the above steps fails to fix the problem then you need to bring the phone to a service center and have it checked as this could already be a hardware related problem.

S7 Heats Up

Problem: When i bought my s7 10 months ago .. i didn’t feel it heats up .. may be went warm at max But now in the last 3 months i began to feel it heats in uncertain periods … even using wifi not data ( am not talking about charging, its in normal using apps that need internet ) Not certains apps do that .. its sometime goes hot othera no .. i do reset factory .. but same …. I’m still on marshmallow .. just do 2 or 3 updates but still marshmallow … it always ask me to update to nougat but i am afraid as i read about heating issues .. but nw i see the same in marshmallow Could u help me plz ?!!!! PS i dont play games on it, just global apps like facebook instagram whatsapp viber …. etc

Solution: To fix this particular problem I recommend that you upgrade your phone to Nougat. Once the upgrade has finished you should backup your phone data then do a factory reset. If your phone has a microSD card I suggest that you remove it before checking if the phone still heats up.

If the issue persists then this could already be a hardware related problem in which case you will need to bring the phone to a service center and have it checked.

S7 Keeps On Rebooting

Problem: I picked up my phone this morning and found that it kept rebooting.  It’ll show an unlocked padlock with colorful swirls circling it.  Eventually it go to the swipe to unlock screen, but it won’t respond.  I finally found out about holding the power and volume down and did a reboot, but now it reboots and lets me unlock it, but when I press the icons it’ll make a clicking noise, but won’t do anything.  Once in awhile I can get the setup to open, but I can’t get any screen to scroll.

Solution: Does your phone have a microSD card installed? If it does then try removing it as this could be causing the problem. If your phone does not have a microSD card or if the issue still occurs even after removing the card then proceed with the troubleshooting steps listed below.

  • Check if an app you downloaded is causing the problem by starting the phone in Safe Mode. If the issue does not occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Wipe the cache partition of your phone from the recovery mode.
  • Start the phone in recovery mode then perform a factory reset. Take note that the reset will erase your phone data.

If the problem still persists even after performing the steps listed above then you will need to bring the phone to a service center and have it checked.
