Hv this serious issue of wi-fi connectivity on my i9500. The phone should automatically connect to the predefined network but it does not. Have to manually connect it after every few minutes. This problem was also faced when it was on offical rom and the problem still persists even when I have flashed Arrow v8.0 rom.
Have no wifi issues on other samsung devices and apple products on the same network. And as per the dealer there's no problem with the phone.
Need help to fix this problem.
