The fact that they do it at all is awesome.
Glad I used them when I got my 2s. Aliexpress or eBay wouldn't coordinate a warranty repair on something like this.

As long as it works, I wouldn't obsess over it.
You could try shutting down your device, pulling the sim, the battery, and rebooting.

Dropped my device from shoulder height today.
Thanks God .. the device landed on one of the corners. The plastic had some marks in it, but otherwise the device is fine.
Never dropped a phone from this height without having it crack.

Cdma devices are horrible at data related tasks, especially things like video calls.
I wouldn't hold my breath if I had requested this feature.

I suggest giving miflash a shot.
It is a Windows program which can reset your phone with original factory settings, including the radio and boot images.

Still waiting for a way to amp up the baseline volume levels for phone calls. The device is a bit too quiet for my tastes when o make calls.

There's a chance that the edge spectrum you tried to tap into isn't available where you tested the phone, but is available near the phone shop you visited.
Glad to hear you got the device working. Enjoy your hongmi.

That's strange, I don't have any bugs like that, and I'm also on the miuiandroid version.
If you think the problem is rom related, you could try installing the.latest stable, official rom, & comparing the call quality.
