We wanted to provide you with an update regarding audio issues on some Moto E (2nd Gen.) phones. The issue has been isolated to a malfunctioning rear microphone on the phone. We are working with Motorola to identify options for resolution.
In the meantime, we have tested a series of settings, cases, and hacks in hopes of finding something to improve your calling experience (including researching what others have said in forums outside of Republic Wireless). Here is the best suggestion that wehave tested so far. We hope that you find this helpful!
Apply a piece of electrical tape over the small pinhole to the left of the camera. TAPE?! Yes, tape. Specifically, electrical tape. The problem with the microphone is the noise cancellation is not functioning properly. In our testing, sealing the mic SIGNIFICANTLY increases call quality (thanks to the XDA Developer blog for this tip).
Don’t have tape, or can’t find it? Let us know! We’ll send you a Republic smudge-fighter! which is a sticker, that ALSO cleans your screen. Stick it on the back of your phone to increase call quality, and also have a nifty screen cleaner when needed.
We'll continue to provide updates here and on the Health and Wellness page.
Thanks again for your patience. Please let us know if we can assist with anything else!
