Asus Zenfone 2: Specifications & Price of World’s First 4GB RAM Smartphone

Asus shared some glorious sales numbers at CES 2015 mentioning that it shipped over 1.5 million Zenfones per month during the past quarter (Q4 2014). Alongside this mighty achievement, Asus also announced two new smartphones – the Zenfone 2 and the Zenfone Zoom to join the Zenfone series. Zenfone 2 is a nice upgrade over Asus’s previous Zenfone devices which were launched at their CES event last year. Let’s take a closer look at the specifications, price and availability of Zenfone 2.

Specifications of Asus Zenfone 2 (ZE551ML/ZE550ML/ZE500CL)

The name might turn out to be a confusion as there was no Zenfone 1, instead there were Zenfone 4, 5 and 6. For those who are feeling that Zenfone 2 is a downgrade over the last gen devices, it is not. Same can be confirmed from the specifications listed below.

Asus has created a lot of confusion as there are multiple versions of Zenfone 2 with different specifications. Please read the detailed specifications on the packaging before purchasing. Specs listed below are not claimed to be fully accurate (Blame Asus for the confusion).

The overall design hasn’t changed much and the Zenfone 2 makes even more use of the similar brushed metal finish which is popularized by the last gen Zenfone devices and loved by the users. The phone’s back is curved and is as thin as 3.99 mm at the edges making it easier to hold and makes the phone look pretty slim. The navigation keys are capacitive and not on-screen if this matters to you.

The power button is located at the top, which might not be an easy access for such a large phone. The pack sports the 13MP Pixelmaster camera and the Dual-LED flash. The volume controls are also pushed to the back in order to keep the sides thinner.

Coming to the features, there are some key additions such as the Kids mode (Parental Controls), Zenmotion (tap to switch to single-handed use), SnapView (Secure apps, photos and files. Also keep separate personal and business stuff),

Price and Availability of Asus Zenfone 2

The Zenfone 2 is scheduled to be made available in March 2015, but it will surely take Asus till end of April or early May before all the target markets start receiving a supply of new Zenfone devices. If you’re from Taiwn, you can already start ordering some of the versions of the phone.

    I dont know how to do a recovery boot nor do I want to screw the phone.
    Take this fone back and give me a refund.
    It says camera has stopped responding.
    Asus launcher has stopped responding.
    Hangs the phone in a while.
    What good is it.
    The camera is not good,battery, no 3G connectivity heats up as
    if its gonna blow.
    I put few drops of water on the back pannel and water drops get evaporated
    quickly. I dont want to be get killed by this phone. Free Ram is now 1gb
    only sometimes 2gb..

    dont buy this phone its a waste

    • Narender Singh October 27, 2015 at 10:51 pm #

      No there are no earphones bundled with the phone. However you can purchase Asus Zenear earphones (~₹700) separately from other sites.

  20. Concern Citizen December 2, 2015 at 7:34 am #

    Please don’t this phone the battery drains fast and the heating issue still exist, intel based phone are no good.

    Try mediateck or snapdragon processor instead.
