Microsoft has officially announced Windows Phone 8.1, but is yet to release it to the general public. That said, the developer preview of Windows Phone 8.1 will be made available to registered developers soon and developers will be the first to get their hands on the final RTM version of the mobile OS once it is released by Microsoft.
If you want to try your hands onto the developer preview of Windows Phone 8.1 and want to be the first one to get the finished version of Windows Phone 8.1 when it does get released, here are the steps you need to follow.
Register as a developer
You need to first register as a developer with the Microsoft developer program. This process is free and you will not be required to pay a single cent / penny for it. Also you need not be a developer to actually register as a developer with Microsoft.
The trick is to register using the free App Studio that Microsoft released recently. Use the same email address as you have used on your Windows Phone handset and register as a developer.
Download Preview for Developers app
Preview for Developers app is basically an app that configures your phone to receive developer previews of software updates that are yet to be released by Microsoft.
Download the app from this location and install it on your Windows Phone handset.
Once installed, run the app and agree to the Terms and Conditions, sign-in using the Microsoft account using which you registered as a developer. Then agree to enable Preview for Developers and click done to complete the process.
Check for phone updates
Navigate to Settings -> Phone Update and tap on check for updates. This will connect through to Microsoft servers and check for Windows Phone 8.1 developer preview.
Your Windows Phone handset should find the developer preview update once available and begin downloading it.
Lots of time, we can increase readability and performance of our app by using good programming practices. Like I was doing once like below:
if (IsolatedStorageWrapper.LoadString(“ShowTipsAndTricks”) == “”)
now this is something we do most of the times, but all this can be done in one line of code as well, see below:
IsolatedStorageWrapper.SaveString(“ShowTipsAndTricks”, IsolatedStorageWrapper.LoadString(“ShowTipsAndTricks”) == “” ? “true” : “”);
The compiler will have to traverse through less lines, and we might some less CPU cycles

Talking Robo app on Windows Phone 8 Store
HTC has finally launched HTC 8x its smart phone series for windows phone 8. Nokia Lumia 920 has already been reviewed a lot, and was into screens earlier. Lets see what HTC brings in.
HTC took the veil of their 8X device featuring Windows Phone 8 recently. The phone looks really good on the paper. First things first, so I will be writing about the specs in the later part of this article. HTC mentioned in the press release that the Windows Phone 8X flagship will be coming with a dedicated audio amplifier apart from the Beats Audio that most of the HTC phones come with. Yes, the phone is actually said to feature a 2.55v amplifier that should greatly increase sound output and push the device’s speaker or any other enhancement connected to its limits.
When I saw the picture of the 8X which is just 0.39” thick, I thought to myself – “how loud can this phone be anyways?”, but seems like the company has put in a lot of effort into this device in order to make it stand out of the crowd. Below is a video shot by WPCentral which shows the additional 2.55v amplifier in action.
As you can hear in the demo, the Adele song is blasting through the phone’s speaker up to a point that you can’t hear what the person is saying exactly. According to WPCentral, it’s difficult to get “real feel” via video, and the additional amplifier is said to indeed make a difference. The audio output is strikingly loud with no distortion. Connecting the device to an external speaker should do wonders, perfect for a media savvy buyer. The music output is pretty powerful going by smartphone standards.
HTC is not known for implementing camera sensors with high megapixels in its device, and company seems to be in tune with that standard even with Windows Phone 8 devices. The device will be making use of an 8 megapixels back-illuminated sensor (BSI) with f/2.0 lens and an ultra-wide angle front-facing camera. The main camera is capable of shooting videos at 1080p HD, which is a great feature to have and can be a selling point too. The phone will be featuring NFC.
The front camera which is 2MP shooter can shoot a view of 88 degree angle, “allowing up to four people and more to be captured at once”. What are your thoughts on HTC Windows Phone 8X.
