Follow this guide to replace a broken, cracked, or non‑responsive screen on your HMD Pulse Pro smartphone.
This guide is for the screen and frame assembly—the screen pre‑installed on a frame—not a screen panel on its own. You'll be removing and transferring all the parts from your old phone into the new assembly.
If your battery is swollen, take appropriate precautions.
