I have had this issue actually with both 3G and 4g ....I submitted a ticket on goggle play. There support department got back to me really quick with things I can troubleshoot with but nothing worked. They asked me to email back with the phones full specs for the enigneers to look at.
I recommend doing the same and submitting a ticket on goggle play...the more who stand up the higher the priorty the fix will be and the quicker it will be done!
I noticed when switching from lte to 3g or vice versa it does stop streaming sometimes. Could it be because of ip address switching? Back server switching?
Well, I received an update to Pandora last night, and did not fix. So I cleared data, un-installed and re-installed the app. Now everything seems to be working just fine...
I get this issue often. I usually put airplane mode off then on and it fixes it. However sometimes I just do a restart on my phone if I think it may be more helpful and am seeing any other issues on the phone.
I'm now having a similar issue with the latest youtube app... sometimes when I open it, and try to start a video while connected to 3G or 4G, the video will never start.
restarting the phone works. I think they might need some bug fixes for certain apps...
