I am an old lady with her first smartphone, a Samsung Galaxy Note 3 running Jelly Bean. Since the last upgrade my email and other apps won't sync and some functions have stopped. Through 'fiddling' I found an auto sync option which I checked but it made no difference. I am reluctant to try a factory reset having read about what gets lost in the process.
I don't understand the technical answers to some related questions so could someone please kindly tell me step by simple step how to correct these errors. I've currently closed all active apps. I don't have many apps downloaded and don't play games etc but I seem to have accumulated a lot of widgets! Do I need to do anything with them please?
