iPhone 6 Plus Says:Panic..We are hanging here!

Lately i am having constant and random resets in my iPhone 6 plus.The phone gets a blue screen and then it restarts itself,or sometimes the blue screen turns red and then white and completely switches off afterwards.And sometimes,when i turn the phone back on,it freezes itself on lock screen (right before slide to unlock line appears)

I should also say that these errors seem to happen when i attempt to unlock the phone from sleep(lock) mode and not when the phone is in actual use.

and just a few minutes ago when i tried to unlock the phone again,i got a blue screen and the strangest thing happened.A big black text appeared on my phone's screen saying,panic...we are hanging here! i took a picture of the screen with my wife's iPhone 5.I will upload it here so maybe someone can help.

I have been using apple products for some years and previously owned an iPhone 3gs,4 5 and never ever seen strange thing like this.

My iPhone runs iOS 8.1.1 and is NOT jailbroken
