JiaYu G4 Vs. Umi X2

jiayu G4 vs UMi X2
Like & Share

Chinese phone makers JiaYu and UMi both have quad-core MT6589 Android smartphones set to make an appearance in the next few months. Let’s take a look at two of the most popular the JiaYu G4 and UMi X2.

JiaYu G4

When JiaYu launched the dual-core G3 last year, they rewrote the rulebook on what a low-cost Chinese smartphone should offer. The JiaYu G4, which is expected to launch after March, is going to raise the G3’s already high bar.

Once on the market the JiaYu G4 will start at 999 Yuan ($160) in China for the base model, with international resellers expected to offer the phone at a higher $200+ price, but even at these largely inflated prices the G4 is going to offer remarkable value for money!

 JiaYu G4 Vs. Umi X2

Being a 2013 Chinese flagship phone, the G4 will follow the proven MTK recipe and will feature the latest quad-core MT6589 CPU running at 1.2GHz and a choice of either 1GB or 2GB RAM. JiaYu haven’t been shy to show off the performance of the 1GB RAM version and benchmarks show the phone reaching 12,251 on Antutu.

One of the standout features on the G3 was the 720HD display, and for the G4 JiaYu have opted to boost the size to 4.7-inch but keep resolution at a respectable 1280 x 720 and PPI 312. The new panel will feature OGS technology which allows for a thinner display and an overall better user experience.

 

Camera’s will also be updated and the G4 will boast a 13 mega-pixel rear camera and 3 mega-pixel front camera. If the rear sensor proves to be as good as the unit on the Newman N2, then the JiaYu is going to be a very powerful device for photos let alone the usual smartphone features.

UMi X2

Last year UMi managed to steal JiaYu’s thunder by releasing the UMi X1 while JiaYu struggled with delays and problems with the G3. The X1 has proven to be a great phone with amazing hardware.

The UMi X2 is a complete redesign and features a body more like a Samsung device rather then than Xiaomi inspired model from last year. Pricing for the X2 appears to be on par with the JiaYu with purported retails prices set at the 1499 Yuan ($240) mark. The good news for international buyers is that reseller don’t tend to mark up UMi phones as much as JiaYu models.

As for hardware, the UMi X2 is practically a low-cost Oppo Find 5 and will feature a 5-inch 1080p display, 13 mega-pixel rear camera and quad-core MT6589 CPU running at 1.2GHz. There will only be one model of X2 which will feature 2GB RAM and 32GB of built-in memory.

 

Like the G4, the X2 will boast OGS technogly and a Corning Gorilla Glass screen, but in a much larger 5-inch size with a higher resolution of 1080HD 441PPI. The screen is said to be surrounded by an ultra-narrow border design which measures just 2.5mm.

Rear camera on the X2 is a 13 mega-pixel unit which is confirmed have a f/2.0 aperture and is able to recored video at 1080p.

Which do you choose?

From a hardware perspective there is very little to choose between the JiaYu G4 and UMi X2, with the only obvious differences between the 2 phones being the screen size and resolution.

But what is more important to you? Are you happy with the smaller 4.7-inch 720HD display on the cheaper JiaYu G4? Or are you willing to spend the extra money for the larger 5-inch 1080HD screen on the UMi X2? Let us know in the poll and comments below!

    hey andi.. when is umi x2 appearing in market?

    • http://www.gizchina.com Andi

      UMi say this month, we actually have more UMi X2 news coming soon.

      • http://GIZCHINA.COM sushil

        please install features like ‘flip to mute’ , ‘Intelligent answer – answer calls just by bringing the phone close to ear’, ‘two windo option’, ‘Face-beautification feature’ etc in Umi X2 mobile sothat it prove smartphone defination.

  • Whyzor

    It also depends on price, if both JiaYu G4 2GB & UMI X2 are both around $240 international shipped, then the latter wins easily.

    • lahkok

      None could be had for those prices internationally shipped, at least for months after its release.

      • http://www.facebook.com/preetam93 Preetam Nath

        Thankfully launches in India too!

  • streetp0wer

    i would gladly take umi , if it doesn’t have a lot of manufacturing troubles like x1 did.

  • c

    Hey Andi, this is the moment when JIAYU realised, that they made the G4 in the wrong way and they made a Big Mistake. Because the UMI X2 will have WCDMA 900/2100 support, this advantage making it more up ahead then the G4 (WCDMA 2100 ONLY !!! this is stupid) and in the other way UMI have the same OGS technology but with 1080p 441ppi :D ! So once the European buyers realise that UMI X2 matching/covering the whole BAND requirements for almost all European WCDMA Networks they will buy the UMI instead of the G4 and I don’t want to mention the other advantages that UMI X2 have instead of JIAYU G4, you already did that in that beautiful post and also to all others reading my post, please check the VOTE and you will see which is better :D
    Oh eyah, I forgot to mention that the UMI will be also in Titanium Grey Color and not only White !!!

    • Daniel

      how sure is that the Jiayu will only support WCDMA 2100? I’d appreaciate if you give a source. Thanks.

    • Whyzor

      Since they all use the same MT6589 SoC, that means the same built-in radio hardware, so same supported frequencies?

    • Nova5lag

      Is this true? I hope not I just ordered a G4 from Merimobile… if it doesnt support networks in the UK I had better cancel that order. :(

    • Daniel

      So, according to http://www.gizchina.com/2013/02/12/umi-x2-network-support/ the UMI will only be able to run wcdma 2100. Jiayu and UMI are even again – however, I would have rather liked to see them on par by both supporting 900/2100 each :-) Fortunately, 900MHz isn’t as common as 2100 – still, that doesnt help if you’re depended on that range :-)
      @Nova5lag: check http://en.wikipedia.org/wiki/List_of_UMTS_networks to see what band your carrier uses

  • cpurage

    I will say only this WCDMA 900/2100 (Perfectly suitable for the European market, cause almost all of the Networks requires WCDMA 900/2100 Mhz ) which is the biggest advantage, that UMI X2 have against the Jiayu G4 and the other advantages Andi already mentioned them … 2GB RAM, 32GB ROM, 5.0″ 1080p OGS, 8,9mm body thinner border then the JIAYU … with one word BETTER

  • usman

    umi x2 will suit in india regarding sim network 2g or 3g i am eagerly awaiting to buy

  • Daniel

    I’m more interested in how the Umi X1s compares to Jiayu’s G4. For 999 yuan, specs are fairly similar except for screen size (4.5 vs. 4.7) which in turn affects overall dimensions…
    Also, Andi, how would you compare build quality of these two brands in general? Oh well, way too many 999Y phones expected for release – doesn’t facilitate any decision :-)

    • http://www.gizchina.com Andi

      From last year’s phones I would say JiaYu are slightly better on quality.

    • http://www.gizchina.com Andi

      Keep posted we will have a comparison soon

      • Daniel

        That sounds nice! Keep up the good work – I really appreciate the information you gather!

  • http://gravatar.com/ironmaiden189 ironmaiden189

    Is the MTK6589 able to display a 1080p video? I saw with the MTK6577 dual core generation that HD videos were easily using all processor power and not smooth at all, so what about this new MTK6589? Is it able to play smoothly an HD/Full HD video?

    • cpurage

      http://www.mediatek.com/_en/03_news/01-2_newsDetail.php?sn=1088

      Please read it, it will answer all your questions. And the Short answer is YES it supports 1080p screens :D

      • http://www.gizchina.com Andi

        Thanks fot the link :)

      • http://gravatar.com/g2-d5bd30ea719bf921b44d25b6c542b366 fred

        thx for the link, What about dual active functionality? all phones with this chip will get dual active?

        • cpurage

          Yes

          • http://gravatar.com/g2-d5bd30ea719bf921b44d25b6c542b366 fred

            That’s really great new features, a lot of people expected this and this is a big plus, i hope the energy consumption won’t go too high, that;s the only thing i’m concerned with

      • Rafy

        Yes it supports the 1080p screens, but the problem is HOW it supports. I saw many smartphone MT6577 with 720p screen that had more lag(in app and games) then the phones with lower screen resolution. I hope that this MTK6589 will be able to support 1080p screen in decent way,because if the choise is between a 1080p laggy phone, and a 720p smooth phone, I choose the 720p.
        P.S. There arent’s MTK 6589 whith MHL/HDMI and OTG support? It would be nice..
        P.P.S. I’m sorry for my English,I’m Italian,btw compliments for your site, I see it every day for china-phone news :D

        • http://gravatar.com/ironmaiden189 ironmaiden189

          I know 1080 is supported by this chip, but HOW?
          @Rafy
          Exactly my point. It’s worthless I have a 1080p screen and I’m not able to use all of those pixel in a decent way. I too prefer a 720p screen able to play smoothly videos and games.

        • http://www.facebook.com/prateek.chatterjee.315 Prateek Chatterjee

          Exactly! And i seriously doubt its capability to render fhd content at all times. The very best of qualcomm chips(snapdragons S4pros SOCs with adreno gpu) based om ARM a15 architecture (currently) are able to render 1080p content without framerate drop and noticeable lag. Will an a7 based 1.2ghz SOC be able to do it without any significant drops in performance? I dont think so…
          However at this price point, it blows everything out of the water…

  • SulNUl

    If stuff like wifi and gps are inbuild in this new chip, that means no more problem with wifi strong and similiar problems which has a lot of nowadays Chinese phones?

    • guapper

      +1
      quality of the WiFi and GPS chipset will make or brake the JIAYU G4. Until this has been tested and/or confirmed the only safe poll choise is the Newman N2

  • Rich

    I’m also a little worried about network compatibility with these phones. Would either (or both) work on UK networks, and if so would it depend on which specific UK network?

  • Jevus

    Sadly even the qualcomm quadcores can barely keep with 1080p, so jiayu aall the way.

  • Kunal Banker

    Hello,

    When can we expect the quad core version from Zopo with 5.7″ display??

  • Gabriel
  • Manos

    JiaYu has better quality! But only the 2gb ram version
    don’t buy again plastic phone!

  • Pankaj

    I think Xiomi Mi 3 is superior over G4 and Umi X2.

    • http://www.gizchina.com Andi

      More expensive though too.

    • cpurage

      Yeah exactly, why you are mentioning a phone which will be with at least $200+ expensive than the UMI X2 ?!

    • lahkok

      Oxymoron

  • Muhammed

    I like the design of the Jiayu G4. A pity is, that all future smartphones’ screens are getting bigger and bigger. 4.3″ is really max for me

    • Manos

      Yes the phones are getting bigger and super big I’m waiting a quad core 4inch and 2gb ram HD screen it will be nice but this will happen at 2014 for sure. For now the JiaYu G2S is good. ..

    • lahkok

      If the 4.7″ HTC flagship proved to be successful we may see finally a reverse of this trend. Cross your finger.

      Though I personally am fine with 5″ as long as they keep the form factor right.

  • http://gravatar.com/itamrpink His Dudeness

    So, UMi X2 has to be compared to the flagship edition of the JiaYu G4, mainly because of the RAM and internal memory.
    They share the GPU model, but the X2 mounts a bigger screen (0.3″ more) with an higher density (129 more pixels per inch), which translates into a far better resolution (1080p vs 720p). The question is: can it bear this? Like others before me said, I’d prefer a smooth 720p rather than a laggy 1080p. Also, the battery is slightly smaller on the X2 (500 mAh less). With a Full HD screen, this will probably be sensed I guess.
    What leaves me astonished is that, even if UMi gave info on the release date, which is near, we still miss some detail and a physical model. Some things are going to be fundamental to me, like dimensions and maximum supported microSD capacity.
    When you get your hands on a X2, can you please make some smoothness tests with some hardware intensive games plus some battery durability tests over various ways of use (idle with 3G, gaming, etc.)?
    By the way, I love your articles and tests. It’s thanks to you I’ve became interested over chinese smartphones, and you are my principal reference point for those. Can you email me as soon as you do an hands-on complete review, or you get some news about the X2? Thanks a lot!

    • lahkok

      Dimension is 135 x 68 x 8.9mm

      You can safely assume that it will support 64GB MicroSD, I don’t think they’ll skimp anything after all those specs.

      I hope someone will come up with an app to lower screen resolution, it’s theoretically possible.

  • leonwangls

    hi Andy, can you explain how the pricing works in china. When the umi x2 price at 1499 rmb. is it the ex factory price or the retail price. I am asking because the price in aliexpress is listed as US$299 to 400. i will be going to shanghai in March so i may pick up a umi but if the price is the same as in aliexpress, i can pre-order it now.

    • http://www.gizchina.com Andi

      The prices we list are the Chinese retail prices i.e if you buy the phone through official channels. International resellers are buying these phones up at retails (or close to retail) then adding their mark up and shipping, which means a $160 phone could reach as high as $280 with shipping for an international customer. However, the good news is that many smaller Chinese phone makers are looking at offering phones internationally and you will see lower prices in the coming months :)

  • datiger

    will these phones work in the usa?

  • parjinder

    Wil these phones work in india ?

    • Muhammed

      Most china phones are international unlocked, so yes, will work worldwide :)

    Does anyone know about NFC capabilities on JiaYu or Umi phones?

  • uzziii89

    Hey guys, Please tell me what phone is better jiayu g4 or umi x2 , i want buy next week and i dont know what to do, i appreciate your answer, thanks.

  • Rajesh sharma

    please do not go for UMIX2 becouse after sale services is very poor, lots of problem in handset, if you call to cc they told you send mobile at your own expense and they will revert you after 25 days. neither they give any replacement in any sense. Poor people,poor management, poor handset quality, only configuration are good but very very poor built quality.

    Go for another brand they might be good but my experience with UMI people are very bad and i made a complaint against them in consumer court for fraud like non replacement.
