I do not have a problem wit WI-FI at all, I am in contact with my daughter and she is in Colombia South America spending some time with family, we already talked about 10 different times and is crystal clear, of course we are using Wi-FI Calling, she is still on GB and I am with ICS 4 (leaked Version).
you get absolutely NO STATIC on wifi calling?
I've read in other blogs that people who put the leaked ICS on their Amaze now suffer from static on their wifi calls.
I also have an HTC One S and that with ICS also has really bad static.
I'm holding off on my ICS upgrade to my Amaze until i read more good news regarding wifi calling after the upgrade.
There is no going back to GB if problems arise after the upgrade.
People have done factory resets and the issues still persists...so the theory that it's left over apps and settings from GB is simply incorrect. I do not have the problem of connection problems or errors that others have, but I do have a problem with latency. There is a pretty large delay on the voice to get to the other party on the line. You're taking a gamble if you upgrade. It's your call. You may or may not have issues. I'd advise against it if you are like me, and have no other option but to use wifi calling.
You will probably get mixed responses ... I got better results so far with WiFi calling with ICS compare to earlier version. Something tells me it has a lot to do with access point you are using and not as much with the OS version on the phone. However, overall ICS is SO much better, I would recommend upgrading.
There are two different factory resets. One only clears /data (phone storage). The other clears /data and the internal SD card. Looks like T-Mobile calls this a master reset. When I reset, I followed these directions after I made a backup of the internal SD card to my PC (mainly to save my pictures & videos taken with the camera).
I should also note that I use two T-Mobile Linksys Hotspot @Home routers (WRTU54G-TM and WRT54G-TM) setup with WPA2, one on channel 1, the other on channel 11, using the exact same security and SSID settings on both. WPA2 allows the phone to be connected to both and dynamically hand-off between the access points.
