Hi..... I'm from Brasil and I dont speak English very well, sorry..... P.S. - I have the stock firmware (v1) For me MX Player is the best player. When I watched a movie I noticed 2 subtitles (see picture) (the movie is NOT hard code). (yellow: correct / white: not necessary) I had a big headache to solve: 1 - go to Advanced Settings (click on the time/weather of MINIX launcher) 2 - select PERMISSIONS 3 - select com.amlogic.SubTitleService and turn off..... Reboot Minix and have fun. P.S. - ES Player and 4k Movie Player will not have subtiltes.
