I'm using A 50S. SMS alerts are not receeiving quickly, when we are using online transactions. Also network issues in interior areas, while other brands don't have the same issues at the same location.
Thanks for your reply. yesterday I've gone to service center & got some instructions. Also I'll modify this settings as your instructions & update later
I'm also having same problem. I think recent models of Samsung phones have this problem.In Earlier models I haven't face this issue Hope Samsung will fix this issue in next update.
