fix my samsung Tab galaxy s 8.4

My samsung galaxy tab s 8.4 LTE is 3 months old . Recently it is giving me troubles. The phone network fails showing a cross sign then display flickers for whilel and the entire device restarts. It happenes less frequently when the device is charging or im playing media or reading books .more frequently when im using net..specially 3g. Using 3g drains up whole battery in 30 minutes! Whats wrong with my tab?

Welcome to Android Central! You might consider asking your carrier for a replacement SIM, in case the current one is faulty and contributing to those issues.

Since it's only 3 months old, you could also either bring it back to the wireless store where you got it and see if they can give you a replacement, or contact Samsung for warranty repair or replacement.
