Try turning flight mode on for 30 seconds and then turn it off and if that doesn't work, try restarting and clearing the cache on your phone, if these don't work then another option is to factory reset your phone and see if that does the trick. If none of the above work then your best option is to take it to a samsung service center to see if they can sort your issue out for you.
No I don't. But I did have a app called shall I answer which was very intrusive so I deleted that. With the update it updated 483 apps. These must be all my current apps and every app I've had for the last 16 years using a smart phone. Is there no way to remove them?
