How can I fix realme c35 broken screen

@kwakuduah you are not giving us much to work with here. Sounds like you have a broken dispaly panel that you would like to repalce.

Since iFixit does not yet have a specific guide for your phone, use something like this video. Replacement displays for your phone are readily available at many online places. While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Repair is War on Entropy!
