S7 Can’t Make Phone Calls

Problem: Galaxy Samsung S7, bought in USA, working fine,  but brought to the UK and unlocked. Initially everything worked fine except mobile data. After multiple attempts EE talked me through manually inputting the APN and I was able to successfully use mobile data. Then the next day I noticed I now could not place phone calls. Getting a no sim or sim error message. Followed your steps: Including the cache and a reboot. After the reboot I was able to place a couple of calls but within 1hr they stopped again. I also had to put the APN settings in again as I now couldn’t message or get data again. Now I can message and have LTE data but no phone calls. Anything else I can do?

Solution: What you should do first in this case is to isolate the SIM card from the phone. Insert your SIM to another phone then check if you are able to make calls or send text messages. If you are not able to do so then the problem could be SIM or account related in which case you will need to have this checked by your carrier.

In case the problem does not occur when the SIM card is placed in another phone then you should proceed with the troubleshooting steps listed below.

  • Try changing the network mode of the phone. Go to Settings – Mobile Networks-  Network Mode. If this was previously a Verizon locked device then try using the Global mode then check the LTE/GSM/UMTS mode.
  • Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Wipe the cache partition of the phone from the recovery mode.
  • Backup your phone data then do a factory reset.

S7 Overheating

Problem: I have the Samsung Galaxy S7. Last night, my phone was on the charger and I got a message saying my phone was overheating so I unplugged it. My phone was at 100% at the time. I never put it back on the charger and the next day it kept saying the same thing, that my device was overheating and I could only make emergency calls and could not open any apps. Since getting the first message, I’ve restarted the phone, wiped the cache partition, soft reset, factory reset, and charged it in safe mode. At no time during any of this has my phone been hot or even warm. The battery is not draining fast and the phone is not running slow. Any idea what’s going wrong with it?

Solution: Does your phone have a microSD card installed? If it does then this could be causing the problem. Try removing this card. In case the issue still occurs even with the SD card removed and since you have already performed a factory reset then the problem could be caused by a faulty hardware sensor. I recommend that you have this checked at a service center.

S7 Battery Drains Fast

Problem: I have had my Samsung galaxy s7 for 11 months. In the past month I have started having problems; The battery will go to 40% and then switch off by itself or it will drain from 60% to nothing in 10 mins so need it on charge constantly.

Solution: It looks like the battery might need to be replaced. You should however check if some other factor is causing this problem by performing the troubleshooting steps listed below.

  • Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Try wiping the cache partition of the phone from the recovery mode.
  • Backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone yet. Try checking first if the issue still occurs.

In case the above steps fails to fix the problem then you should have the phone checked at a service center as this could already be caused by a faulty battery which needs to be replaced.

S7 Screen Takes Too Long To Respond

Problem: Hello. I just bought a new samsung galaxy s7 a few days ago and I am experiencing some problems with the display. Sometimes it takes while to respond when I turn on the screen. Or the screen won’t turn on (in the evening it wa ok, in the morning I try to turn it on and it won’t react. Buttons light up but not the screen. I did a reset (turn on and volume down button) it worked ok but later it happened again. I also have the same issue when I turn off the always on display mode. I ran the phone in safe mode and so far the issue is gone.. so in your article it is stated that if the issue happens in safe mode you should perform reset etc. But what to do if the problem is gone in safe mode? Should I take it to service or can I do something myself to solve the issue? Thank you for your time. Have a good day.

Solution: If the problem does not occur in Safe Mode then it is most likely caused by an app that you installed. You will need to perform a trial and error method to find out what app this is. Start by uninstalling one app then restart the phone in normal mode. If the issue persists then proceed with uninstalling another app. Repeat this process until you get to the point where the problem does not occur after uninstalling an app. That app is what’s causing the problem.

S7 Text Messages Fail To Send But Are Received By Recipient

Problem: Just got my wife the galaxy S7 through straight talk. When she sends a text it said message failed after spinning forever then a exclamation mark is put beside it in a circle. But the texts are being sent what should we do!!

Solution: The first thing that you need to do in this particular case is to make sure that your phone is running on the latest software update. If it already is and the issue still occurs then proceed with the troubleshooting steps listed below.

  • Restart the phone by pressing and holding both power and volume down keys for at least 10 seconds. Check if the issue still occurs once the phone has restarted.
  • Clear the cache and data of the text messaging app from the application manager.
  • Start the phone in Safe Mode then check if the issue occurs in this mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Wipe the cache partition of the phone from the recovery mode.
  • Backup your phone data then do a factory reset.

S7 Screen Went Black

Problem: My screen just went black. the phone was not responsive but i could receive calls and notifications. At first half of the screen was white then it went black. Please help

Solution: The best way to proceed in this case is to start the phone in recovery mode then check if the screen works in this mode. If it does then the problem could be caused by a software glitch in which case you will need to perform a factory reset in this mode. In case the screen remains black then it’s very likely that this is a hardware problem already in which case you will need to bring the phone to a service center and have it checked.
