[NEWKNIGHT]

what is your issue

[indiantrueindian]

yes, your device supports knox security version 3.5..but at the same time..it runs on one ui core so it isn't possible to install/ run secure folder in it

i will not be able to use secure folder?

[TerM1na7oRatWAR]

no..

[Yazdanirfan]

what about good lock

[TerM1na7oRatWAR]

Good lock also runs on the full ui... so no good lock too..

You cannot use Samsung Pay or good lock and also your phone has one ui core version as M series because your phone is a low end mid ranger although it supports knox but you can use Samsung S secure app
