Tempered glass screen protector TelForceOne for Oppo A40 / A40M, 2.5D edge

Tempered glass screen protector TelForceOne for Oppo A40 / A40M, 2.5D edge provides full-screen coverage with a slim, rigid layer of glass that protects the front display from scratches, daily wear and minor impacts. The glass preserves the original touchscreen responsiveness and display clarity while the 2.5D rounded edges ensure a smoother touch transition and compatibility with most phone cases designed for Oppo A40 and A40M.

Advantages

This tempered glass offers high surface hardness to resist keys, coins and other sharp objects, reducing the risk of visible scratches. The protective layer helps absorb light shocks and distributes impact force to lower the chance of display damage. Optical transparency keeps colours and contrast close to the original screen, and the glass maintains accurate touch sensitivity for tapping, swiping and gesture controls. Rounded 2.5D edges improve comfort during use and reduce chipping at the borders.

How to use

Before applying the tempered glass, clean the phone display thoroughly using the included alcohol wipe and microfiber cloth to remove dust, fingerprints and oils. Peel off the protective layer from the adhesive side and align the protector with the front camera, speaker and edges of the device. Gently place the glass from one side to the other and press the centre to allow the adhesive to spread; use a card or cloth to smooth out any remaining small bubbles toward the edges. If large dust particles remain, lift the protector gently and remove debris with a dust sticker before reapplying.

Usage recommendations

For best results, apply at room temperature on a clean, flat surface and avoid touching the adhesive side. Replace the protector if it becomes cracked or severely scratched to maintain display protection and touch performance.
