I am having bad connection recently started two weeks from Today May 23,2016. In the past i get very consistent 4g lte but 2 weeks ago i notice i only get 4g and lower and even with only 4g my connection is really slow. I get slow text, no ringing sound when i make a call, when i can call frequently people on the other line cant hear me, and alot of messages that say "server access failure please check network and try again". Anyone else having this same issue. DO you think the new update to android 6.0.1 is the reason for it messing up my phone? any other people experienceing this and are there any remedies to my solution? i dont want to do a factory reset just yet.
