My Samsung Galaxy s6 edge overheats when it isn't even hot.

[AC Question]

I had my Samsung Galaxy s6 Edge for 2 months and it started to fail when I was watching youtube. It showed a message for a connected dock and showed a overheat message. I tried to look on google for ideas and a message said that I couldn't use any apps but my phone and contacts. It also said I couldn't call or text anyone. I am still trying to figure out anything.

Welcome to Android Central! Try wiping the cache partition: https://support.t-mobile.com/docs/DOC-21095. If that doesn't help, try Safe Mode, to see if the problem is being caused by a 3rd party app: https://support.t-mobile.com/docs/DOC-21007

If the problem persists in Safe Mode, then bring it back to the store where you bought it, or contact Samsung for warranty repair/replacement.
