Reviews for the Asus Zenfone 4

75% ASUS ZenFone 4 Smartphone Review
Source: Kitguru English
On the whole, the ASUS ZenFone 4 is a decent little phone. It doesn’t do anything exceptionally well, but it doesn’t try to. What it tries to be is a dependable budget phone, and it mostly succeeds. The display works fine. Granted, it’s not the vivid display on the iPhone 5s, though they may be the same size – but the ZenFone is a whole lot cheaper. ZenUI, too, remains sleek and simple, though slightly more fiddly due to the smaller screen.

If you’re looking for a budget blower, don’t waste your money on this - save up a teeny bit more and grab yourself the latest Moto G or even the Moto E. Its paltry display, bulky build and muddy resolution doesn’t do it any favours, and you’re better off spending your cash on something with a bit more quality.

70% Asus Zenfone 4 review: One of the best low-cost smartphones you can buy
Source: English
The Asus Zenfone 4 packs lots of features into a tiny package. But the budget price means that the phone has cut corners, which is evident in the low-resolution display and underpowered processor and camera. Yet, there’s lots to like about the Zenfone 4: the design and the build quality is one of the best we’ve seen on a budget phone, it’s simple to use and basic functions run smoothly. It also lets you boost the storage with the SD card slot. If you are cash-strapped, looking for an Android phone that provides good value for money, the Zenfone 4 is one of the best phones you can buy at the moment. Though not all, it checks most boxes to be a solid budget smartphone. However, if you need a slightly better display and battery life then go for the Moto E.

Asus ZenFone 4/5/6 video review: A trio of smartphones in different sizes and prices
Source: PC Advisor English
Overall, we're pleasantly surprised by the Asus ZenFone range. There's a smartphone to suit everyone here, whatever your budget and whatever screen size you prefer. We're excited to see what Asus has up its sleeve next, and we expect rivals will be curious and perhaps slightly worried, too.

60% Asus ZenFone 4 review: A new entry to the budget smartphone category that could scare rivals
Source: PC Advisor English
For £99, we're impressed by the ZenFone 4. It's nicely designed, has brilliant software features, is suitably speedy and has decent battery life, but it's not outstanding. We'd like to see a slightly better camera and the addition of 4G connectivity. We'd suggest checking out the EE Kestrel and the Motorola Moto G 2014 as alternatives to the ZenFone 4, but it's certainly a worthy contender and we think you'll be satisfied if you decide to go with this good budget smartphone.

The Asus Zenfone 4 is a phone that looks and feels a bit like a smaller version of the Motorola Moto G. However, in use it sits a few rungs below Motorola’s budget phones. The Asus Zenfone 4 is affordable and looks good, but there are a few too many core issues with the screen and battery life to make it a champ.

The Asus Zenfone 4 is a sound first try at a phone for the masses. However, there are just a few too many problems for it to be a really great alternative to the several great £100 phones out there. It’s not really a case of missing features, much as we’d like to see 4G in the Zenfone 4. It’s more that the poor battery life and uninspiring screen mean the phone doesn’t really stack up against either the Motorola Moto G, or the cheaper Moto E.

The Zenfone 4 is a frustrating tale of two phones. There’s the compact, user-friendly 4-inch smartphone that sports a colourful design, slick performance and a neat interface. Then there’s the phone that struggles to last from sunrise to sunset, that has you keeping one eye permanently on that ever-decreasing battery meter.

70% Asus Zenfone 4 A400CG Review: Rounding Out the Family
Source: NDTV Gadgets English
The Zenfone 4's screen is pretty bad but nearly everything else is outstanding. We're particularly impressed with the device's camera capabilities. Full HD video recording is pretty neat, and it's nice to have a front camera - more so one that isn't terrible! We're looking forward to the A450CG revision which has a totally different screen and have high hopes that Asus will improve on this phone's one weakness.

This is one of the smallest diagonal for smartphones.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.
