I've had my EvoLTE for almost a month now. Already on my 3rd one. First one the kickstand fell off, second one the screen magically cracked before my eyes, and now this 3rd one has this issue.

Put the phone in the Sprint car dock, plug in jack, and get this random screechy-scratchy noise that essentially ruins any music playback. Phone volume through speakers licks balls too.

Pulled phone out of car dock, but left jack plugged in, and noise instantly stops.

Add this to the list of wrong with this phone. Should've stuck with my OG.

Did you try another plug...?

It's only audible when charging and plugged into the AUX jack. On different chargers and stereos.

Unplug the charger, noise stops. AC charger, car charger, don't matter.

Makes listening to music from the car dock unbearable.

It's the road noise interference. Common problem with aftermarket stereo systems. They make noise filters for aftermarket systems but not for this application.

I have the same issue with this phone.

And I said "This phone" because I've used an iPhone, Nexus One, EVO 4G, Nexus S, and EVO 3D in this exact same car, exact same cables, and the LTE is the only phone that has this problem.

It's an issue with your car, buy an adapter called ground wire isolator and add it behind your car stereo,you will be golden for life or simply buy an aux cable with built in ground isolation...its not the phone...does the noise get louder as you accelerate?

Okay, after more research, it is definitely a ground issue and it is an issue with many different kinds of phones. While I suspect it is the case design of the LTE with the metal trim, THERE IS A SOLUTION

I purchased and just tested the Kensington Noise Reducing AUX Audio Cable and it did as most others on Amazon said it does... it kills the problem. It can be had for as little as $13. It has 4 1/2 out of 5 stars with 150 reviews, mine soon to be added. So I hope anyone else coming to this board will have an easy time fixing their problem going forward.

Cheers,

I have the same problem in my truck, it started when I plugged my XM radio and started using that. I looked this problem up on other forums and I think this will help you nicely:

Had the same problem with my Galaxy Note. The "Aux Noise Filter" app solved the issue for me:
