Thanks for the reply. I asked because earlier this year I dropped my 6S+ (which was housed in the Apple leather case) on a marble floor (hotel lobby). The phone landed face down...thanks to the smooth floor and the lip of the case, there was no damage. I rarely drop things - but sometimes things just happen. That's why I would be afraid to use a phone without at least a minimally protective case to lessen impact on hard surfaces when dropped. So I wonder if tempered glass screen cover + 3M film would have been enough to keep the phone intact (with just a screen cover replacement needed) in the same scenario.
Yes, just having glass screen protector and 3M film body protection is not enough for protection in case of falls. That is why I use leather sleeve pouch. When I am not using the phone, it is normally in the sleeve pouch. It is only when I am using the phone that it is not in the pouch. I should have put the phone in the sleeve pouch at night when charging. I normally do, but like I mentioned earlier, the 3M film needed some time to dry up as it was still a big sticky at the corner edges which was attracting the felt from inside the sleeve pouch. Sad thing is that it was better and I should have starting putting the phone in the pouch over night. Oh well, it had to happen.
Overall I am very careful when handling my phone and since the last 2 years since iPHone 6 Plus I have been very careful except the unfortunate incident this morning,due to the charging cable. May be it should have not be kept so freely on the desk next to my bed.
