Incoming or outgoing calls

[Sa82]

Is anyone else having issues with not being able to receive incoming calls or make outgoing calls. Ever since the new update

My latest update was on April 23rd which hasn't affected my calls @Sa82 

Try the following.

Soft reboot by turning your phone Off and On.

Then if necessary …

Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone. 

Then if necessary …

Put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
