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.
