Guru look man, I’m very hard on hardware with two children and haven’t seen any issues. I do have a made in China model and not a made in India model tho.
Edit2: I did destroy my first CMF1 phone within the first few days by scratching the digitiser from the behind (sounds dirty) by inserting something too long in the accessory screw hole (sounds dirty again). And I scratched the rear of the digitiser and had continuous fantom touch when on. I couldn’t even unlock the phone, so make sure you didn’t do what I did trying to hack it.
Edit3: make sure your accessory screw isn’t thermally expanding and scratching the rear of the digitiser.
