Thank you. But not waterproof obviously I undestand in case of dropping it into the water. If they show us tests of 4m depth for 20 or 30 min and then 1ml for 1milisecond destroys a component of it (the front speaker in this case) that's certainly a failing product / or a lie. We cant use words to account for massive elastic meaning like this. 'Water resistant but not waterproof' including destruction by 1ml 1mlsec of cleaning is not right any way we look at it.
To the over time point: never ever even rained over this phone, much less any other contact with water other than wet cloath for cleaning. And never a chemical product.
