So I figured out a roundabout way to fix the I Phone 6 frozen screen problem (not caused by water), (I personally and still in love with my 5s, its not mine, but since I am a little more tech savvy than my other half I have repeatedly fixed his phone) First of all lets start with the problem; if you graduated from an older smaller model to the 6, the buttons on the new phones sides are softer, not hard press ones, inadvertently people used to holding their phones in their palms, and encasing them with their fingers etc, are actually pressing the buttons by accident, while trying to swipe the screen with their other hand---you are confusing the computer telling it to do/not do multiple functions, so it freezes....always hold phone in an open palm, or loosely around the base, the second problem is a heavy hand on the screen; one barely needs to touch it to enable functions. With a larger screen on the i6, it is more 'bendy', so people pushing hard on the screen and pushing the screen into the motherboard causing it to disable the phone....ok, the solution, obviously you can go back to factory settings etc...but my other half has done this, only to continue to abuse his phone continuously and continue to make it freeze...try this alternative solution if your screen freezes: double click your bottom start button to engage Siri, tell her to send a message to one of your contacts, say your random message, like "Hello" after doing so, you will be prompted to send or edit message, at this point you will be able to interact with your touch screen again...simply GENTLY, edit your message manually to for example "Hi". then hit the send button...you will now be back to your home screen with a functioning phone.
