Hi, after updating my device to the latest version, i have encountered a new problem which happens quite frequently. My sim card will disconnect and connect multiple times in a short span of time. The wifi will also not work each time it happens. I have tried ejecting and putting the sim card back and the problem still persist. I have also done a factory reset but to no avail. I hope someone can tell me what i need to do to fix this problem as it has never happened before since i first bought it new on February this year.

Thank you.
