It is absolutely impossible to avoid dust and air bubbles getting trapped under this screen protector. I've installed screen protectors on many phones and tablets over the years. This is definitely the worst quality. When I peeled off the bottom layer under the protective film in a clean room, I immediately noticed tons of dust particles adhering to the underside of the protective film. From the factory, this dust got trapped between the screen protector and the bottom cover. From this point on, there was absolutely no way to achieve good adhesion without bubbles between the Autel display and this "screen protector". I wish I could get my money back, but I've already passed Revain's return period.
