The Good: The Huawei Ascend Y530 is very affordable, its battery is replaceable and it has expandable storage. The Bad: Its screen is poor, its processor doesn't offer much power, Huawei's software is clunky to use, its battery life is weak and it doesn't have 4G. The Bottom Line: While the Ascend Y530 is pretty cheap, its all-round unimpressive performance means it's still not worth your cash. For the same money you can buy the Motorola Moto G, which beats the Y530 in every respect. Huawei may have recently impressed with its sexy, metal, 7-inch , but the Chinese firm is still keeping its hand in the budget end of the mobile market. At only \u00a3120 SIM-free from Argos (it's only available in the UK), the Ascend Y530 is undeniably cheap, but you don't get a whole lot for your money. Its 4.5-inch display has an 854x480-pixel resolution, it has a dual-core processor, older Android 4.3 Jelly Bean software and it doesn't have 4G LTE.With a \u00a3120 price tag, it's going head to head with -- a phone that scored highly thanks to its great screen, capable processor and cutting-edge Android KitKat software. With lesser specs all round, the Ascend Y530 is going to have a serious fight on its hands to convince people to part with their cash over the Moto G.Design and build qualityBudget phones are typically uninspiring things to look at and the Y530 is no exception. I'd charitably describe its plain black design, textured back panel and rubberised edging as "functional". Suffice to say that if you're looking for a sleek, stylish mobile, this isn't going to cut it for you. Its affordable price means that's somewhat forgivable of course, although the Moto G with its colourful interchangeable back panels has a smidge more flair.At least it feels pretty well put together. There's no flex in the chassis and the rubberised strips should be able to protect it from at least a few bumps. The volume and power buttons on the side all have a satisfying click to them and there's no unpleasant rattling or loose panelling that suggests it'll fall apart the first time you drop it.At 132mm long and 66mm wide, it's comfortable to hold in one hand and you won't need to stretch your thumbs out too far to write a text. If you're not keen on 5-inch+ beasts, a 4.5-inch phone like the Y530 may be more up your street. If you're after a compact body that still packs in the power and performance of high-end phones, however, check out .Around the edges you'll find a micro-USB port with a 3.5mm headphone jack sat on top. The back panel is removable, as is the battery hidden beneath it. Inside is a microSD card slot, allowing you to expand the meagre 4GB of internal space. You'll really need to use a card, as you'll blow through 4GB in no time at all -- particularly as 1GB of it is already taken up by the Android operating system.DisplayThe Y530's 4.5-inch display has an 854x480-pixel resolution, resulting in a pixel density of 217 pixels per inch. That's a disappointingly low amount, even for a budget phone. By comparison, the Moto G's 4.5-inch display boasts 326ppi. Side by side, the Moto G's display is considerably sharper, with much crisper edges around icons and small text.It's not just the resolution that's disappointing either. It has a rather cold colour cast to it that makes whites look rather grey and drab, it's not particularly bright and it doesn't have great viewing angles. The Y530's screen doesn't really get anything right. For your email and making calls, it's fine, but it's not going to do your Flickr gallery justice.Software and processorThe phone runs on Android 4.3 Jelly Bean. That's not the most recent version of Google's software -- that honour goes to 4.4.2 KitKat -- but it's recent enough to be forgivable, considering the low price. You probably won't immediately notice the older software anyway, as Huawei has heavily skinned it with its Emotion user interface.Emotion UI makes quite a few tweaks to the standard Android look. Crucially, it's ditched the apps tray, forcing you instead to have all of your icons scattered across numerous homescreen panels. Once my favourite live widgets were placed down among the apps, the home panels quickly became a confusing mess. On the upside, it's highly customisable. You can select from a variety of themes that change the background colours, the app icons and even the transition animation you see when you flick between homescreen panels. You're also able to show a simplified homescreen. Instead of a scattering of app icons, it displays essential tools like the phone, text messaging and the Web browser as large tiles. It's designed to make it easier for new Android users to get to understand and I think its simple layout certainly will help. It's undeniably easier to navigate than its standard cluttered look.
