9H hardness
Please note that 9H in the tempered glass industry actually refers to pencil hardness, not the well-known Mohs hardness (Pencil 9H Hardness = Mohs 6H Hardness). Each batch of OTAO tempered glass needs to pass the strict Japanese Mitsubishi 9H pencil load hardness test.

Sensitively compatible with 3D Ultra-sonic Sensor
The flagship models of Samsung S10, S20, S21, Note10, and note 20 series all use Qualcomm's ultrasonic fingerprint recognition, which greatly improves the security of unlocking. But it also brings great challenges to the tempered glass industry. At present, 95% of the tempered glass screen protector on the market cannot support ultrasonic fingerprint recording and recognition very well. However, OTAO tempered glass screen protector has been greatly improved in the stability and accuracy of fingerprint recognition through continuous research and development and improvement.
