help ESR Tempered Glass Screen Protector FAQ
What does 9H hardness mean for an ESR screen protector?
The "9H" rating means the tempered glass has a hardness level of 9 on the pencil hardness scale, making it highly resistant to everyday scratches. This ensures coins, keys, and sharp objects in your pocket won't leave permanent marks on your phone.
How many screen protectors come in an ESR Tempered Glass pack?
ESR typically sells their screen protectors in multi-pack configurations of two or three units. This provides users with backup replacements in case the first application fails or the glass gets cracked later on.
Does the ESR tempered glass affect iPhone face recognition?
Most ESR tempered glass protectors are precisely cut with a specific cutout or edge-to-edge design to ensure Face ID works seamlessly. The glass is kept thin enough around the notch to prevent infrared interference.
Do ESR screen protectors leave residue when removed?
No, because they use a dry silicone-based adhesive rather than liquid glues, they do not leave any sticky residue on your screen. The adhesive acts more like a static cling that prevents dust from getting underneath.
