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.

Easy Installation

The installation of OTAO's tempered film is very simple and convenient. If you are considering the terminal, you can also choose our applicator(also called installation tray)to assist the installation. Even a consumer without film experience can easily put a film on it.

Bubble Free & Dust Free

In order to save costs, many factories produce in a non-dust-free environment, and it is easy to absorb dust into the product AB glue, and some dust is difficult to be found if it has not undergone strict quality inspection after production, until they are attached. You can see it on the phone, it's too late.

Some factories use low-quality AB glue, and air bubbles may also appear.

OTAO adopts high-standard quality inspection procedures, from raw materials, production environment, production process to final storage, strictly controls, and delivers a qualified dust-free and bubble-free tempered glass screen protector to you.

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.
