Hey guys, I recently purchased a Nexus 5 32GB to replace my HTC IncS. It is running stock android and kernel, but rooted. I am on Amaysim in Australia (on the Optus 3G network) with connection preference set to 3G (as i don't have 4G service on my plan). My problem is whenever I am in a call, I get my 3G data speed reduced to unusable speeds. This didn't used to happen on my old device, anybody else having this problem?
