This is the limit test of Honway nano diamond coating
This is to prove that after the nano-diamond coating, if the phone is accidentally dropped into the water and taken out immediately, there will be no impact. This phone is HTC M7, which is used by Honway. After testing, the sound quality of the headphone jack and the sound amplification are not affected. It is still in normal use. The surface hardness after coating can reach 8~9H. If you have any questions, please contact Honway, or add the official line account @honway to reply you immediately.
