GALAXY S6 CAN’T MAKE OR RECEIVE CALLS

GALAXY S6 CAN’T MAKE OR RECEIVE CALLS.

My phone will not make or receive calls. When I dial a number or choose a contact, and select “call,” the call screen comes up and it says it is “dialing…” but it is completely silent (there is no ringing sound), and after 20 seconds or so, the call is ended without me doing anything. The same goes for receiving. When someone calls me, I swipe to answer but there is only complete silence, and after 20 seconds or so, the call ends on its own.

I know that this problem has nothing to do with lack of service, airplane mode, network connection, or volume/ muting problems. To date, I have had no previous issues with the functionality of my phone. This is the first problem I have encountered. I am utterly confused and would appreciate help. Thank you! â€"Troy

Solution: Hi Troy. First off, you have to make sure that this is not network related. If you have a GSM phone, make sure that you try the SIM card to another phone to see if call functionality works as expected. If you happen to have a CDMA phone, or if SIM card on your GS M phone works on another device, make sure that you do 2 things â€" booting in safe mode and/or doing a factory reset.

Here are steps how to do them:

How to boot your Galaxy S6 in safe mode

Safe Mode will come in handy in your case as it will temporarily disable all thi rd-party apps leaving pre-installed ones and core services running. If one of your third party applications is preventing calls from coming in and out, safe mode should help you check it.

Once the phone has booted in safe mode, its performance will dramatically improve, app crashes will be gone and you can do whatever troubleshooting procedures you need to do to regain your phone’s top-notch performance. Here’s how you do the safe mode reboot:

• Press and hold the Volume Down and Power keys for 20 to 30 seconds.
• Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
• Your phone should continue booting up and you will be prompted to unlock your phone as usual.
• You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
