I have been having trouble all day with my RAZR. I am currently on the 4G network and the signal strength and 4GLTE logo are both blue. However, when I try to use an app or the browser only the "UP" arrow under the 4G logo is lighting up. From what I understand this means my phone is sending data. The "Down" arrow is not lighting up so I assume this means it is not receiving data. Does anyone know what will cause this to happen? I am nowhere near the top 5% of data users to where my data would be throttled.
