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.
Apart from the inbuilt amplifier, which is of course a good selling point and will definitely make the device stand out of the crowd, HTC 8X will be sporting a dual-core processor clocked at 1.2 Ghz, though there’s no information on the brand or chipset being used. Coupled with 1 gig RAM and 16 gig ROM, the phone should be snappy. Yes, most of the high end smartphones are coming with 2 gig of RAM these days, and it is fast becoming a standard, but seems like Windows Phone 8 is not that RAM hungry and 1 gig should be just sufficient enough. It is equipped with a 4.3” display (720 x 1280 pixels) that at 342 ppi has an extremely high pixel density.
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.

At times we need to see how much memory our system is consuming at any stage. Just add the below line under the code:
Debug.WriteLine(“After loading of pictures ” + (Convert.ToInt32(DeviceExtendedProperties.GetValue(“ApplicationCurrentMemoryUsage”)) / 1024) / 1024 + “MB”);
Say after loading of images in a listbox, add this line and you will see that how much memory all images are taking after loading on wp7 screen.
Here is a snippet on how to play a sounds on any event in windows phone 7.
var stream = TitleContainer.OpenStream(“resources/Sounds/button-3.wav”);
var effect = SoundEffect.FromStream(stream);
I was recently encountered by a terryfying windows phone 7 memory problem, i was creating an app in which images were downloaded from the internet. On first screen there were around 16 images of sizes upto 300KB max. But eventually at the end of rendering the memory taken up by the app was 80 to 90 MB. This was surprisingly aweful for me, as Microsoft will refuse to certify your app if you exceed the memory limits. Here’s the relevant section of the certification guidelines.
5.2.5 Memory Consumption An application must not exceed 90 MB of RAM usage, except on devices that have more than 256 MB of memory. You can use the DeviceExtendedProperties class to query the amount of memory that is available on the device and modify the application behavior at runtime to take advantage of additional memory.
What to do, What to do, thoughts… The dilema was that on the very next page, i was going to download even larger images, and that racks up the memory to 270+ MB.. and eventually “Out of memory” exception. Other big problem is that when wp7 page navigate to other page, it keeps the previous page’s memory intact, I definately need to wipe out memory when it moves to next page.
I tried with GC.Collect() making null every Webclient object, even the control which had images i set that to null but the problem persisted. I was using a BitmapImage object, i set the object to null as well and GC.Collect, but that did’nt do it either.
Then i came to some heaven blog and found a solution that, setting the BitmapObject to null would’nt do it. But if i set the source of the bitmap Object to null, that will sort things out.
This cleared the image cached into Bitmap Objects.. and the app was memory happy again. I hope this helps all the guys who are banging there heads on windows phone 7.
