Nokia Asha 302 review
The Nokia Asha 302, with its old-school S40 operating system, modest camera, QWERTY keyboard and chunky shape is no hero handset. But it offers classic Nokia values for social net-workers with a better than decent spec for a very reasonable price. It's not the lightest or the thinnest, but it's solidly built with a sturdy metal and plastic casing and fits comfortably in the hand with its gently curving sides.
Design
The poky 2.4in display's 320x240-pixel resolution won't keep you coming back to watch tons of video, but it displays web pages fine (with fast access too via Wi-Fi or 3G). It isn't touch sensitive, but that's not really an issue on a screen as small as this, and while the D-pad beneath isn't as sensitive as the optical touchpad on recent BlackBerrys, it gets the job done without any fuss. Surrounding it are six well-placed keys, some of them programmable, so you can set up your shortcuts how you like them.

Surrounding it are six well-placed keys, some of them programmable, so you can set up your shortcuts how you like them.
The 37-key QWERTY keyboard is a compact marvel, with neatly rounded keys made of tactile rubberised plastic. They're responsive, with a good amount of give and you can get up to a fair pace with two-thumb texting. The number keys are laid out in standard keypad format too, making it easier to dial a number with one thumb.
Software
Nokia's clunky S40 operating system might be on the way out, unable to keep pace with the fast-changing evolution of Android and Windows Phone. But while it's not swish, and it doesn't offer the selection of active widgets you'll find on later S60 handsets, it still allows you to keep all your favorite shortcuts on the home page and alert you when you get messages or social network updates.

Facebook and Twitter are both on board already, as is WhatsApp instant messaging. There's also a limited range of other apps available from the Nokia Store, but no LinkedIn.
Performance
In use, it feels fast, helped no doubt by the surprisingly powerful 1GHz processor, which opens apps without fuss and seemed to have no trouble streaming video from YouTube either.

The 3.2-megapixel camera offers a maximum 2048x1536-pixel resolution and while it might not look like much on paper, it offers a range of features, including multi-shot, timer and effects. It will also take decent quality snaps, certainly the equal of 5-megapixel versions you'll find on most HTC handsets. Video quality drops to 640x480 pixels, which is scraping the limits of acceptability.
There's just 100MB of memory on board, but you can add up to 32GB via the microSD slot hidden beneath a plastic cover on the side. The battery held up very well indeed, still going strong after two days of steady use.
Conclusion
No, the Nokia Asha 302 isn't at the cutting edge of mobile tech. But it's a solidly built, reliable workhorse aimed at social networkers with a great little keyboard for a reasonable price, and certainly gives the Blackberry midrangers a run for their money.

Facebook Home Ported to all Android Devices
Yes, it’s been done. Whether that’s something to squeal in joy over or cringe in disgust about is up to you. However, that’s besides the point. Facebook’s ‘exclusive’ product reserved for the HTC One, One X, One X+, Samsung Galaxy S3, S4 and Note 2 (Don’t ask why there’s no love for other devices) debuted in the Play store on 13th of April, 2013 and has garnered a lackluster two-and-a-half stars rating with near 2 thousand votes. Want to know what’s the hype about? Read on.
After a bit of modding with the Facebook and Home APKs, XDA Senior Member theos0o has successfully ported Facebook Home to all devices running Android. Both rooted and unrooted phones may take advantage of this port and get a taste of what things are all about, requiring users to simply download and install the 2 APK files provided. A reboot may be required if the app does not run at first. However, all previous versions of Facebook installed must be uninstalled to make way for the modded version of Facebook that’s required, thus root access may be necessary if your device came preloaded with Facebook in order to complete the process and get Facebook Home up and running.
Now, does Facebook Home live up to the hype and expectations? Well, it depends. If you were expecting a simple and minimalistic launcher that conveniently displays your Facebook news feed with scrolling images and quick access to Facebook Messenger and app drawer, then you may want to check it out. If you were expecting a sophisticated and intuitive home launcher that’s comparable to Android, then it certainly does not. There’s no support for our beloved widgets, the wallpaper cannot be changed, and the amount of Internet data and memory it consumes will be unbelievable.
