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.
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.
