I could not download secure folder or s secure in m M30s. I was using this application in my previous samsung mobiles. without this application this mobile is similar to any other cheap brand mobile.
Hello,Your previous phone was supported by knox security.But M30s doesn't have knox security software which is necessary for Secure folder.So you can't use it in your current phone. Also S secure is supported in this phone. Search it on Galaxy App store and download it.
