1. S4 Black Screen after Application Stopped Working

Problem: I was scrolling through Instagram only phone and it stopped. Then I received a message saying “Unfortunately the application has stopped working” or something like that. Then, I turned the phone off because it froze. When I went to try and turn it on the screen was just black but it was lighting up (the back and setting key at the bottom of phone). Then that little light at the top kept blinking. The phone is completely black I haven’t dropped it or anything. What do I do?

Solution: It’s possible that this issue could be caused by some software issues. To troubleshoot this problem you need to start your phone in recovery mode then wipe its cache partition. Restart your phone then check if the issue still occurs. If it does then you need to do a factory reset from the recovery mode. Take note that this will delete your phone data so make sure to do this as a last resort.

2. S4 Black Screen After Deleting System Files

Problem: There is an option in King Root in which it allows you to delete pre-installed files or apps or other things that are undeletable. My issue is that I deleted around 100 files that I wasn’t supposed to delete.it warned me at the end, but it was too late and I had already pressed the delete button.so now I have a black or blank home screen with other things on it.so how do reinstall the stuff I deleted or is it possible to do a hard system reset? If not, is there a solution?

Solution: Try starting your phone in recovery mode then do a factory reset. If this does not resolve the problem then you will need to flash your phone with its stock firmware. You will need a copy of the firmware file as well as the latest version installed in your computer to do this. Detailed instructions on how to perform this procedure can be found at several of the popular Android forums online.
