Screen protector alignment frames

Getting glass on straight is the one step most people struggle with. A frame takes the guesswork out of it.

Short answer

Yes, if you've never fitted glass or your phone has a large screen. Clip-on trays (like Spigen's EZ Fit) are the most reliable; auto-alignment boxes with a pull tab are the easiest. Without one, use the tape-hinge method.

The tape-hinge method

  1. Clean the screen and dust-sticker it.
  2. Lay the glass on the screen with its backing still on, lined up exactly.
  3. Stick two strips of tape across one long edge, from glass to phone side, as a hinge.
  4. Flip the glass open like a book, peel the backing, and close it back down.
  5. Press from the centre outwards, then remove the tape.

Common tray mistakes

  • Using a tray from a different model: the glass will be offset even if it seems to click on.
  • Leaving a case on: trays are made for the bare phone.
  • Pressing on one side first, which pushes air to the other.
