I have S7 Edge for about 3 months. In this period there was no problem. but it crashed recently. my device restart automatically. at first it hangs and then 2 second later it restarts. screen fix on this sentence “Samsung Galaxy S7 Edge” and become slightly warm. one time i waited for 2 hours and it didn’t load. but i have a way to load it, by pressing Volume Down key + Power key. every time i should do this. when i shake my phone i hear a sound that indicate there is something wrong with its inside. i guess it may because of battery but i tried a number of ROMs and that didn’t improve the situation. — Hamed
Solution: Hi Hamed. Firstly, we want to make it clear that hardware issues can’t be fixed by doing software solutions like factory reset or flashing custom ROMs. If your device has been accidentally dropped or exposed to liquid/moisture/extreme heat, there’s no point doing anything on your end. You must either have the phone repaired or replaced.
Secondly, the sound when you shake the phone may be indicative that something is loose inside. We tried shaking our own S7 in our lab and we can’t hear any sound coming from the inside at all. This means that the main reason why your phone keeps crashing most of the time. That flashing a number of custom firmware did not help at all is another proof that there’s no software problem involved here. If the device is still covered by a warranty, we suggest that you contact Samsung so the hardware can be checked.
Hello. My Samsung Galaxy S7 Edge is not charging. I have been using a different cable for the last two weeks. But today it is not charging at all, it is showing the charging light and symbol. But not getting charged. I tried the rebooting through the wipe out of cache, and it worked. It reached 23% and stopped working and in the last 10 mins it dropped down 10% and is stuck there. Please help me out here and the phone is 7 months old. — Rihan
Solution: Hi Rihan. In majority of cases, charging issues are caused by bad hardware. It can be the USB cable, the charger itself, the battery, the charging port, or an unknown problem with the motherboard. To check if hardware is indeed to blame, we recommend that you try all software solutions in this case like booting in safe mode and factory reset. For reference, these are the steps on how to do them.
Boot the S7 in safe mode
- Turn your Galaxy S7 off.
- Press and hold the Power button.
- Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
- Continue holding the button until the phone finishes rebooting.
- Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
Factory reset your S7
- Turn off your Samsung Galaxy S7.
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
- Once highlighted, you may press the Power key to select it.
- Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
- Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
- The phone will now reboot longer than usual.
Remember, if nothing changes after doing these software procedures, the problem must be on the hardware side. As mentioned, it can be any of the following:
- the USB cable,
- the charger,
- the battery,
- the charging port, or
- an unknown problem with the motherboard.
Make sure that you check each of them to see what needs to be done. If using a different USB cable or charger won’t improve the situation, submit the phone for repair or have it replaced.
Problem #3: Rooted Galaxy S7 Edge stuck in Samsung logo screen | Galaxy S7 Edge can’t access safe and recovery mode
Hi. My Samsung S7 Edge got bricked. i bought it in Kingdom of Saudi Arabia (KSA) and used here in the Philippines. I already rooted my phone and had an issue with the display (4 gray lines). i thought it’s a software issue. i tried to hard reset it to return it to default setting. once i entered the recovery menu my phone got suddenly got locked because the of FRP. I researched how to unlock and i read that i need to flash the official firmware again. So i did it using KSA firmware. After i flashed the firmware, it got worse — i got stuck in the SAMSUNG LOGO and i can’t access safe mode nor recovery menu. What i can only access is the Download menu for flashing firmware. I went to Samsung technical support they told me i need to replace the MOTHERBOARD. And it’s almost the same worth of buying a new S7 EDGE. Please help me. — Mark
Solution: Hi Mark. Our blog does not provide root- or flashing-related issues. 99.9% of issues such as yours are caused by a specific misconfiguration of an unofficial software so that’s beyond our knowledge to fix. You must reach out to the developer of the ROM or root software you’re using if you want to get to the bottom of the problem.
You also want to make sure that you flashed the right firmware for this model. There are hundreds of S7 firmware out there and using an incorrect can lead to problems. This is one of the other reasons why we don’t support flashing-related issues.
If Samsung has checked the software of the device and recommended a motherboard replacement, that’s one way of saying they won’t touch your phone because it’s been tampered with. It also means that the unofficial software modification has probably damaged the bootloader (that’s why you can’t load the recovery menu) and there’s nothing that they can do to fix it.
The only thing that you can do right now, since unit replacement is out of the question, is to flash another stock firmware.
Hi. Wanted to see if my phone is fixable – my phone had got wet, but not soaked or put under water, just some drops here and there. I put it in the sun for a few hours, placed it in a bowl of rice for days. It didn’t come on. After about 2/3 weeks, i decided to plug it in and see what happens. After a few minutes, i noticed it started charging. I was all excited. Everything seemed to work fine, but I had to go back to ATT store to get chip since I had to go back to my old phone. But by the time – i say after 2 days- it went off but I hadn’t charged it. I plugged it back in and now the battery thing pops up on the screen but that is all it is doing. Pops up, then goes off. Sometimes the Samsung Android S7 Edge will pop up but then goes back to the battery. Does not show any sign of charging. Do you know why it is doing this and what can be done/fixed? Thanks for your assistance. — Tracey
Solution: Hi Tracey. First off, we want to make this point clear — when it comes to water damage issue on a smartphone, anything can happen. Unless the phone is opened up and a thorough motherboard check is done, there’s no way to know what the problem might be. The only way to know where the problem may lie is when problems or signs of problems start showing up. So, for example, if the screen starts acting up after a device has been exposed to liquid, you can assume that the screen assembly may have been damaged. The best that armchair technicians (like us) can do is to tell you that this or that may have been damaged. To know if your phone can still be saved, you must have it examined by a qualified personnel. No amount of software tricks or troubleshooting can help you in this regard.
Secondly, exposing the phone to direct sunlight was not good. If you left it long enough, that action may have damaged the battery inside, contributing further to the problem. A Lithium-ion battery like the one in your phone can get damaged if exposed to heat. For smartphones with removable battery packs, you can check for the telltale sign of battery damage by checking if there’s a bulge/s in the sides. Obviously, you can’t do this since an S7’s battery pack is built-in with the motherboard. This is just another reason why a technician needs to check the hardware.
Needless to say, the best thing that you can do right now is to turn off your phone and have it checked as soon as possible. If you have access to a local Samsung repair center, we strongly recommend that you let them handle the repair for you. They may charge you for it but at least you know that the device is in good hands. But then again, as we’ve said, anything can happen in a situation like this. Having your phone repaired by Samsung technicians does not necessarily mean everything will be back to normal. If the motherboard has been exposed to liquid and there’s extensive damage, even Samsung may not be able to save the device.
Hi. Your articles are always useful and helped me in the past. My Samsung S7 Edge, was working perfectly but suddenly stopped charging and reached 0% yesterday. When I connected to the power outlet it was showing the charging symbol on the black screen with 0% and a blinking dot at the bottom indicating that the phone is charging. But never moved from 0% even after a few hours and phone did not start.
I checked the charger and the cable by connecting to my other phone – Samsung S5 and it charged properly. So there was no problem with charger or cable.
Today when I reached office and connected to the charger at office, it suddenly started to charge normally and within seconds reached 18% and now charging normally.
What could be the problem and do I need to send it to Tech for any hardware check? My warranty is expiring in another 20 days. So I need to take a quick action. Please suggest. — Thanks in advance. Regards. — M Srikanth
Solution: Hi M Srikanth. The battery may have simply been emptied and it took a long time to charge back up. It’s also possible that there may be a bug that prevents the operating system to read battery level incorrectly. In this case, you want to retrain the OS again on how to read battery level correctly, also known as battery calibration. Battery calibration is a good way to start here. Battery Stats, an Android operating system feature that tracks battery capacity can sometimes be mistaken. It may at times give the false reading causing the phone to automatically shut the system off. To rectify this, calibrating the battery must be done. Here’s how it’s done:
- Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
- Turn the phone on again and let it turn itself off.
- Charge the phone without turning it back on.
- Wait until the battery says it fully charged to 100%
- Unplug the charger and turn the phone on.
- If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
- Unplug the charger the turn the phone on again.
- Use the phone until you drain the battery down to 0.
- Repeat the cycle once.
You can also try to wipe the cache partition to ensure that the device uses an updated system cache. Sometimes, updates or app installation can corrupt the system cache, which in turn, can lead to some apps acting erratically. Here are the steps on how to wipe the cache partition:
- Turn off the device.
- Press and hold the Volume Up key and the Home key, then press and hold the Power key.
- When the device logo screen displays, release only the Power key
- When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- Press the Volume down key to highlight ‘yes’ an press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
Hi. I was wondering what my situation was with my phone. My phone turns on and off normally but has a problem when it comes to charging. I did every step that was stated on your website but simply could not get the results I wanted. Whenever I plug in my phone while it is on, the part above the home button does the water effect then glitches, turns black, then a small x appears on the bottom right then the bottom left. It then proceeds to stop charging. I tried safe mode and factory reset and there is no change at all. If I try to charge it while it is off the phone shows the battery symbol with no charge logo on the middle.
Please Help, and Thank you. — Mike
Solution: Hi Mike. Refer to our suggestion for Rihan above to try and fix the charging issue. For the small “x” that appears when the phone is connected to a charger, disabling any app/s that’s related to Samsung Gear VR may help. We’ve noticed this problem for users who installed Samsung Gear VR related apps like the Oculus app. It’s either an app issue (although we honestly don’t see a logical explanation why that’s so), or there’s a problem with the charging port, which triggers the operating system to set up the Oculus/Samsung Gear app. If it’s a charging port issue, then there’s nothing that you can do about it. You must have the phone repaired or replaced.
To check if it’s an app issue, check Application Manager and see if you have any app that’s related to Samsung Gear VR or Oculus. Once you’ve identified that you have one of those apps, make sure that you wipe the cache and data, or disable it altogether. Here’ s how:
- Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
- Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
- Once in there, click on an application.
- You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
- You should now clearly see the Clear Data, Clear Cache, or Disable buttons for the application.
