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

Posted on November 6, 2010 by OZ

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:

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”.
You might be able to use it overseas and avoid ridiculous roaming charges. You just need a decent WiFi connection.
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.

SD Card unexpectedly removed [Android]

Posted on October 29, 2010 by OZ

Today while I was trying to take a picture of my son wearing his costume with my new HTC G2, got the error message “SD Card unexpectedly removed”. I asked myself: how is that possible if the card is inside and even behind the battery.

Before I continued trying, decided to turn off the phone, extract the card, clean the contacts and try again. Everything went well until 20 minutes later; I got the same error again.

I performed the process again, this time thoroughly cleaning the pins on both the G2 and the SD card. I was able to record my son’s parade and even upload to YouTube, but yet again the error message came up once more.

Searched on Google, called a friend and even called T-Mobile to see if there was any known issue. Didn’t get too much help so I went ahead and performed a CheckDisk with repairs (while plugged in to the USB port of my PC). I thought it was fixed after it, but minutes later, again the issue reoccurred.

I decided to use a MicroSD adapter, plugged into my computer, tried to save whatever I could from the latest pictures and videos I took (luckily it was just 2 weeks worth) and formatted it like 3 times. I did not choose a quick format option just to ensure that all blocks get touched.

All good? No. Seems that the card is bad. Called T-Mobile, called, HTC, there are no replacement cards for the HTC G2 yet. What? It is a universal card! But no, HTC says that I need to call when they get stock parts for the HTC G2.

I guess I am out of luck on this one. I will need to buy another card.

Luckily, all the previous contents were safely backed up to the cloud.

Figuring out Android internals

Posted on October 19, 2010 by OZ

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:

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

From Palm to Windows Phone to Android

Posted on October 18, 2010 by OZ

I have been a hardcore Windows Phone user (formerly Windows Mobile, and CE) for several years, mainly because it was very easy to synchronize directly with Outlook and Microsoft Exchange. The GUI has been pretty nice since the first releases and resembled Windows in a way.

Windows Phone let me transition from a Windows CE PDA (Toshiba E335) which was a great jump from the Palm m125; years 2006, 2003 and 2001 respectively. By the end of 2005 I wanted a true PDA/Phone that wasn’t as bulky as the HP iPaq. T-Mobile launched the SDA (HTC Torando) which to me was a godsend. It had Wi-Fi (WPA-PSK support) and bluetooth, running Windows Mobile 5.0. It could play MP3s, Video and synchronize with Outlook/Exchange. The form factor was similar to a dumbphone. It was one of the best phones I have ever owned and prompted me to create a web page with streaming broadcasters posted here.

In early 2007 I bought a T-Mobile Dash (HTC Excalibur) and was able to live with it for 2 years running several cooked Roms (thanks to XDA forums). I had the opportunity to run Windows Mobile versions 5.0, 6.0, 6.1 and 6.5. The latest was the most stable one and the fastest considering the outdated hardware. Many people thought it was a Blackberry.

In 2009 I bought the HTC Touch Pro 2 (HTC Rhodium) Runing Windows Mobile 6.0. I wanted to keep it stock as much as I could for warranty purposes but had problems with the clock and was never able to sync up properly. I decided to go ahead and install a cooked ROM. Since then It as been running different releases of the Energy Rom. I was happy about the capabilities of the phone but had too many OS reliability issues. A reboot every day was not out of the norm, and in some cases several of them on the same day.

Last week I decided to pursue the Android route; T-Mobile just delivered me a brand new HTC G2. The phone is by far the fastest and the most intuitive phone I have ever owned. It is running Android 2.2 and integrates seamlessly with Exchange, Gmail, Facebook and Twitter. There are tons of applications for Android and includes Text-to-Speech directions integrated within Google Maps. Android is light years ahead of Windows Phone 6.5.

I still will try a Windows Phone 7 device and have very high expectations about it.

Next post will be about the Android SDK and how to root the phone to push an application.
