Arc S stucks after the new software

[Matkamiiz]

My arc S stucks a lot(in one day 5 times then i have to restart it again) after when i did the last official update for the phone. Can I take it back somehow or what should I do?

If that wasn't happening before you did the update I'd suggest to run the Repair Phone option on Companion just to confirm if the software wasn't installed properly on your phone on the last update you did.
