My phone is back down to the "creeps along" mode - I tried the suggestion from the VZW store gal - switch to 3G, then back to 4G/3G - and that had no effect. I know folks are posting/comparing max speeds on this thread, and frankly, my phone will often get great speeds! My max was 38.85 mb/s just a week ago. But, for some reason, the phone gets stuck in some mode where the download speed is cut down to around .35 mb/s.
This morning, I tried a more methodical approach to figuring out what's causing this. I tried closing each running app one by one. Then, I ran speed test in between shutting down each running app. No difference here either, it just stayed stuck in "creeps along" mode with a min of .16 mb/s and a max of .61 mb/s. Ran the "Go Task" widget to clear apps - it closed 19 apps, no difference in download speed from that either. Other things tried that make no difference:
1. Turn off debug mode.
2. Disable option for non-Play Store apps
3. Airplane Mode on/off
4. Disable/enable data
5. Background data on/off
Just frustrating. Really? You have to pull the battery to get good 4G performance... Really?
I am done with it being "the network" or "the towers" or "the sim card" or pick your excuse... The some part of the software stack is buggy. Plain and simple.
