I have had several issues since the last update in June. My screen doesn't auto rotate in several apps, I'm getting weird internet security warning and sign in failures for email. The phone is sluggish and crashes from time to time. I have done soft resets and cleared the cache and it fixes it for a day or so and then I start having the same issues. Is there something else that I can do to fix it? If not since I have had the phone for less than a year, is this something covered under warranty?
Thanks.
