Motorola's followed up on the update that's coming the Atrix 4G, which might or might not actually do something about reported call quality issues. In a statement, Moto admits that there is "a very small number" of users having issues, and that they're looking into it. Here's the statement in its entirety:
Motorola Mobility is aware of a very small number of ATRIX 4G users who have reported low audio issues when placing voice calls. Motorola ATRIX 4G is designed and tested to meet our high standards for audio quality. As part of our longstanding commitment to delivering high quality products that our customers love, we believe in reacting even when identified issues impact only a handful of users. Motorola is evaluating further optimization of audio levels in a future maintenance release. Any consumer who experiences this issue should contact a Motorola customer support center.
Motorola takes great care to ensure devices are developed with quality in mind. We appreciate consumer feedback and will continue working to refine our product experience.
Here's how we see it: Motorola knows hardware, and they know call quality. If there's an issue here, they'll fix it. And sooner rather than later, we'd gather. So everybody sit tight and let's see what comes out of this one, and in the meantime share your thoughts in the Motorola Atrix 4G forums.
