Use this guide to replace a broken screen on your Nokia G42 5G.
This guide is written for the genuine Nokia G42 5G screen assembly. The assembly consists of the screen and midframe together as one part. Make sure you have the correct part before you begin this repair.
Note: This procedure requires transferring your phone's internals into the new assembly.
For your safety, turn on your phone and allow the battery to discharge below 25% before starting this procedure. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery looks puffy or swollen, take extra precautions.

Hi Lee, sorry to hear that you experienced issues during your repair. Could you provide me with additional information about which step / action caused this? If you assume the repair is not salvageable, please contact Nokia's phones support to get further support.
Pretty straightforward. Followed instructions to the letter - everything went back together fine.
I followed the Instructions and it worked perfectly. Ready in under 1h.
Unacceptable..., screen assembly parts are out of stock.
Could you make it more friendly to users?
