TG protector sure helps. This was what happened to my uncle's iphone 6+ few months back. I applied TG protector on his phone when he first gotten the phone. One day, he accidentally dropped his phone from waist level when he was retrieving his car and the phone screen cracked. Initially, he thought TG protector was cracked, so he removed the TG protector. But, only to realise that it was the phone screen that had cracked as TG protector was still in one piece with no chip or scratches. He quickly pasted back the TG protector onto his phone screen to prevent the screen from fall into pieces. Luckily, he had bought Applecare+ and had his damaged phone replaced 1on1 with $108 topup. Afterwhich, he bought a better casing and applied new TG protector on his replacement phone. Last known, he dropped his phone again and the corner of the phone screen was cracked. He plans to do the replacement again before Applecare+ expires next year.
