So if someone can tell me about which apk to edit (must be settings apk), file, file location and what to look for in that file.
I am on temasek 4.4.3 ROM for GT-i9300. Only screen timeout mode it has is 15s, 30s, 1min, 2min, 5min. Even in QS tiles it doesn't have infinite or never screen timeout mode. I would like to include that myself. If it is possible by just editing some files and compiling and decompiling some apk. But i have searched so much on google and still can't seem to find out which files to edit.
