As we mentioned in the introduction the HTC One SV comes running Android 4.0.4 Ice Cream Sandwich, and while we expect an upgrade to Jelly Bean is almost certainly on the cards we're surprised it didn't ship with it out of the box.

HTC One SV review

HTC's Android overlay is in play as well on the One SV with Sense 4.1 installed – which also isn't the latest version of the software with the HTC One X+ which arrived last year sporting Sense 4+ alongside Jelly Bean.

Software disappointment aside the HTC One SV at least packs a relatively good amount of power with a 1.2GHz dual-core processor and 1GB of RAM under the hood.

Coupled with a responsive screen Android runs smoothly on the One SV, allowing us to glide through the homescreens – of which you can have a maximum of seven – and skip through the app draw without hassle.

It's not quite as zippy as the likes of the Samsung Galaxy S3 or Sony Xperia Z, but we wouldn't expect it to be and even though its dual-core processor isn't as punchy as the chip in the One S, the two handsets are pretty much on par performance wise.

HTC One SV review

In true HTC fashion the Android lock screen has been dabbled with to include the Taiwanese firm's famous ring-pull unlock process with four shortcuts allowing you to jump to key apps right from the off.

Anyone who has a soft spot for quick settings in the notification drop down will be disappointed with HTC as with its other handset the One SV doesn't provide any here, with a link to the full settings menu the only reprieve.

It's not a critical issue as a widget can be placed on a homescreen giving you control over the main functions such as Wi-Fi, Bluetooth and GPS but seeing as the notification bar can be accessed from the lock screen it would have been nice to see the controls there too.

Hold down on a blank space on any homescreen and the widgets menu will spring up, with a plethora of HTC widgets alongside the stock Android ones giving you a wealth of choice.

A simple drag and drop will see the widget of your choosing plonked onto the homescreen and a similar action will delete it if you hover over the "remove" icon at the top of the screen.

Apps open swiftly and a handy little feature on the HTC One SV is the ability to use the multi-tasking key as the traditional Android menu button by just holding it down – allowing you to easily access additional settings in applications which are yet to adopt the new button-less operation Google is pushing for.

The multi-tasking menu itself has been given a Sense 4.1 makeover with large portrait thumbnails arranged in a horizontal line giving you a clear over view of your recently used apps.

You can force close apps running in the background by sliding you finger up, over the thumbnail to save on data and battery consumption, as well as quickly flipping between various apps.
