Help Audio out crackling using 4g

[thammink]

My razr max is 2 days old now and audio crackles when using the 3.5mm jack into my car, radio, surround sound, computer speakers all using different cables. It happens whether there is music playing or not. It only happens when 4g is on and there is 4g activity happening. So most of the time. It gets worse when browsing or updating etc. 3g there is no issue

I went to the local verizon store and we tried 4 other razr maxxes all showed the same symptoms. Anyone else having this issue? Or is this a bad batch of phones or something? Anyone have any ideas?

4G signal will bleed into unshielded audio cables.

This was never a problem with 3G (evdo), however it's been an eternal problem with ATT 3G (gsm). If you have ever been on ATT, and used your phone as an audio device, you know exactly what I'm talking about.

Most modern devices, like bluetooth to FM are immune to this. If you are using an audio cable, try a better quality audio cable.

A good example, start a download/stream on 4G, then move your phone next to your cheap external computer speakers.
