Hex Editor Free

Hey developers, so I downloaded this app and I thought about buying the pro version at first but I'm kinda glad I didn't. When I tried to open a game ROM and edit some data, it said it couldn't open from storage/emulated/0, then I also had an issue with the search function being stuck with the spinning circle. So I don't recommend this app for opening data of a file. However the app has a cool matrix-like user interface!

It couldn't open files in my Android 10. It also didn't show as launch option. Worse, ads are very intrusive (every time [OPEN FILE] is clicked, bam, loud annoying ad on the face, which cannot be closed with the [BACK] button, only clicking on the [X], which is, obviously, randomly placed by the loser that programmed the ad interface).

It won't request root and just flashes an error message, and My Nexus 6 is rooted and on latest Carbon rom with Magisk installed. NMM File Explorer and Hex Editor are ad free and rooted fine though. I just wanted to get rid of joycon lag but my ROMs file system seems to be structured differently. This is flashing error message " cannot change shell, is your phone rooted? Can't change handler inside thread Thread[pool-8-thread-*random numbers 1-8*,5, main] that has not called Looper. prepare()
