How to replace LCD and touchscreen on oppo a5 (2020)?

@dudiernandhy since you know it is cracked, you will just have to go ahead and replace the display. Since iFixit does not yet have a specific guide for that, use something like this guide. It was written in Spanish, so use a browser that will translate it for you (if needed) Replacement displays are readily available at many online stores.

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 the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
