Asus Zenfone 4 review: One of the best low-cost smartphones you can buy - Tech2


. Does the Zenfone 4 put up the same show in the budget category? Read our detailed review to find out.

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...

Asus ZenFone 4 review


The ZenFone range was originally unveiled during CES 2014 in January, but have only just been introduced to the UK. The ZenFone 4 is available to order from Asus now for a bargain £99.

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....

Asus Zenfone 4


Is it hit, miss or maybe for Asus' Moto G rival?

Decent internal storage at the price, Fair day-to-day performance, Colourful design, Feature-packed camera app

Rubbish battery life, Non-IPS screen, Interface fiddly in places

Asus ZenFone 4 hands-on review


From our very limited time with the device we were actually surprised with its performance. Other smartphones in the ZenFone 4's price range are incredibly laggy to use; while this smartphone wasn't lightening quick, we didn't really experience any...

The Asus ZenFone 4 has the makings of a really good budget Android smartphone, it's got an incredibly cheap price tag and a good set of specs, if the device remains unlaggy in the long-term, like it did when we used the phone then it should be very...

Asus Zenfone 4 Review: In Depth


We review the Asus Zenfone 4, a £99 Android handset that's pretty small but still packs in some decent features, including a nippy Intel processor and 5-megapixel camera.It's never been a better time…

Easy to grip and use one-handed ; Nippy Intel performance ; Surprisingly good typing ; ZenUI well thought-out

Woeful battery life ; Moto G boasts sharper visuals ; Camera features hit-and-miss

ASUS ZenFone 4 Smartphone Review


Continuing our look at the ASUS ZenFone range – today we review the smallest of the lot, the ZenFone 4. Very competitively priced at just £99, the ZenFone 4 aims for those on the tightest of budgets but who still want a complete smartphone experience....

Pocket-friendly ; Decent camera ; Beautiful UI ; Very cheap at £99

Awful battery life ; Lots of bloatware ; Fairly thick

the ASUS ZenFone 4 looks a good option if you need a decent phone on a budget, though the Moto E 2nd Gen may be worth a look too.

Обзор смартфона Asus ZenFone 4


Младший «зенфон» может похвастаться WVGA-разрешением, TN-матрицей, разными цветами задних панелек и отличной скоростью работы

К качеству речи есть определенные претензии, собеседники жаловались на глуховатый голос, да и я слышал их не очень хорошо.
