WiFi Calling Feature Does Not Work Properly With Bluetooth Enabled And No Headset [HTC G2]

T-Mobile started to roll out OTA radio upgrades and Wifi Calling in the past couple of days. Mine was updated yesterday and I was really exited to try it. At first it did not work and left for work. Then came back to try it again and it did;  I even got a couple of calls at night with no issues. Today calls dropped to the point that was almost unusable. I researched online and found out two cases of users having the same exact issue and pointing Bluetooth as the culprit. They were right. As soon as I disabled Bluetooth, WiFi calling just worked beautifully. It is a bug that T-Mobile will need to patch quickly.

Now, what does WiFi calling means for your plan and phone:

  1. It will use the alloted minutes for your current plan, for the bucket you are currently on: Peak, Nights, Weekends or MyFavs. I double checked today and ensured that all calls made were recorded as “Weekend”.
  2. You might be able to use it overseas and avoid ridiculous roaming charges. You just need a decent WiFi connection.
  3. Your phone is likely to use more battery as WiFi will be on all the time. So keep a spare charger or MiscroUSB cable handy.

I have also read that tethering was going to be part of this OTA update. I have not found the option yet, but will comment about it as soon as I do. Right now I am focused on ensuring that WiFi is flawless while in my house which has really bad reception spots, including my home office.

Enjoy your G2.

Figuring out Android internals

My first task was to change the ringtone to music I used to have in my Windows phone. A simple search let me to a guide with this information:

Music/ – Media scanner classifies all media found here as user music.
Podcasts/ – Media scanner classifies all media found here as a podcast.
Ringtones/ – Media scanner classifies all media found here as a ringtone.
Alarms/ – Media scanner classifies all media found here as an alarm sound.
Notifications/ – Media scanner classifies all media found here as a notification sound.
Pictures/ – All photos (excluding those taken with the camera).
Movies/ – All movies (excluding those taken with the camcorder).
Download/ – Miscellaneous downloads.

These are under the media folder located in the microSD card. As soon as the Android phone is plugged to a PC, a USB Mass Storage device is detected and drivers are installed.

My second task was to have the ability to browse the storage card within Android (kind of File Explorer on Windows Phone). I found Astro file manager and installed it.

My third task was to find applications I used often in other environments and install them into the device. TweetDeck, Foursquare, Skyfire, Retro Radio and Google Reader came to mind. Facebbok and Twitter apps came pre-installed.

Fourth task. Figure out why is my device losing signal in my house. This is ironic because I used to laugh at the iPhone 4 when all the articles of bad reception popped up a week after it was launched. Several sites started posting funny pics about it. Well it is just bad luck as my Windows Phone has better reception. I figured out spots where I can leave it and let it get some signal.

The situation prompt me to ask a question on Twitter. 2 mentions came back quickly pointing out about WiFi calling. This is why Twitter is so awesome!

So my fifth task was to research about Wifi Calling and try to make it work. Well this wasn’t as trivial, as I needed to follow these steps:

  1. Download the Android SDK and install
  2. Install USB drivers – but seems that this method did not work properly in my machine
  3. Download proper X64 USB drivers
  4. Download the T-Mobile Wifi-Calling App
  5. Plug in the G2 to my PC
  6. Enable usb debugging option in the device
  7. Open the Device Manager, find out the new device that has no drivers and update it with the ones you just downloaded
  8. Open the command prompt window and change the folder to “tools” under the android SDK folder
  9. Issue adb commands:

I installed the Wi-Fi application but seems that T-Mobile has not enabled it on their end. I will wait and post as soon as I get any success using it.

Enjoy your [soon to be] Android phone.
