Bshut din se ye sunta aa raha hu magar abhi tak koi update to nahi aya or ayaga k nahi? Batao to my dear friends 

Your device has been rooted. Samsung pass cannot be used on rooted device for security reason. Ye show karti hai.Maine odin se firmware change kiya tha.. iss k bad ye problem face kar raha hoo.. phirse purani wali firmware bhi install kiya but nahi h...

I cannot open this app. I open  some time this app but showing couldn't connect secure folder, something went wrong. If this problem persist. Contact customer service. So can i fix it anyone help me?

My device a50s month by month not send any update? Give me 1 update after 2 month. It's  company  problem  or mobail?
