My windows phone slowed after mango(7.5) update.anyone having same?

Hi nikhilrj, It may happen due to less vacant of memory space or RAM utilization of Mango, i have read in a forum in att about this same problem, they ve suggested to backup the phone memory and then adviced to format it.. you may consult the samsung store if it is still covered under warranty.. Cheers..!! V

maybe mango 7.5 is too hard for your phone. it's not compatible or maybe you can use series under mango 7.5
