Hi Jason

Bought 3 pieces of the 0.15mm Glass-M for Note 3...about 3 weeks ago..

Very happy with the product until one one them showed with a hairline crack...

the most abusive situation this phone is subjected is in a jean's pocket..

Could it be defective??? Any Warranty ???

the hairline crack...

I concur with you totally ..."there's no way a glass could break if no impact was made on it"
That's why I m surprised to see the hairline crack ..
I definitely did not drop my phone.. I m very careful of that ..
definitely no hard impact or poking by sharp object too would not risk doing such thing to my Note 3... even though "protected by premium tempered glass screen protector with 9H hardness"

I supposed it is just my bad luck for getting a "weak" Glass-M, even so.. i still the product for it's thinness (maybe too thin!!), its super clear & smooth screen and it's "Anti-oil oleophobic coating" no more frustrating finger prints.

Looks like have get replacement... so please PM me the price for a another piece..

Cheers
