One more just to keep up the momentum :) : whats the chance of custom roms on this phone? i.e. CM, MIUI, AOKP etc.

The Jiayu G2, like most newer Mediatek based phones, supports 3G over 900 and 2100 mHz.
If anyone knows more details it'd be great if you could share.


I've found a chart that tells you what frequecies are used for 3G over the world. The only confusing one seems to be the U.S.A., and I would recommend checking with your provider first which bands it is using for 3G.
Most European countries seem to use 2100, which is supported by the G2, and supposedly all other phones with Mediatek chips.

Cracking review sir, really good read. With regards to the camera, I don't know what people are expecting but those are the best images I have ever seen from an android phone for £100, of course the S3 and OneX will be better but they cost at least 3X as much as this, seems pretty damn good for the price point.

Apparently the G3 has been delayed again, this time supposedly some case issues but to be honest I think Jiayu may have missed the boat on that with the quad core MTK's just round the corner, although I still really like the G3 design. Ill probably pick up a Xiaomi M2 when it drops as my M1 has served me well, but when the quad core MTK phones drop might try and pick up a cheap one too.

I think the G3 looks a bit ugly, to be honest. I haven't had hands on with a MT6577 device powering a 720p screen. I know that the chip maxes out at that resolution, I'm not sure how much of a hit on performance pushing that many pixels will have.

Slim. On the eJiayiu board there are a few custom ROM's, but these are just skins over the stock kernal with fancy launchers and icon packs. You probably won't see any real custom ROM's, but the ICS implementation is solid any shoudn't give you any problems.

Neat chart, looks good for 3G compatibility.

Thanks very much for the review. I liked it so much I decided to take the plunge and buy! :-o

What convinced me was as follows:

1. IPS screen of just the right size for me
2. Really large battery
3. The dual sim feature, two cores, 1GB RAM
4. A good design that looks non slippery and won't scratch easily
5. The 168 USD price tag for all of the above!

Do we know if the MTK6577 can be overclocked?

Though an established community would usually be my prerequisite, my instinct tells me to chance this one! Oh well, the future will tell.

Some cheap clone devices claim to have the 6577 clocked at 1.2ghz, but I'm not sure if this is an actual overclock or just fudged specs and numbers.

Undervolting that CPU to stretch the monster battery would also be nice.

I wonder if ROM developers will take an interest. Oer perhaps it's too late - I see many of them in the Huawei G300 forums! :-/

Great review... just a couple of questions please.

How can you update the firmware when it becomes available ?

Does it have OTA updates available in the settings menu ?

I have been to the Jiayu website and Chinese is not my forte ,so I understood very little.
Can us English people be able to update the fw easy enough ??

thanks and my Jiayu G2 dual core should arrive tomorrow.. so excited.

Hi, Nice review.
I have seen in other places that Jiayu G2 may only support 3G on 2100, not 900. ¿Can you confirm that it has the 900 band? Usually if you enter engineer mode there is a "Bandmode" section to confirm this, although I do not know the code to enter that, on a rooted phone that should be easier...

@ aaroNiGHTs

Thanks very much for the resources mate. I also came across your root guide here.

http://www.modaco.co...-g2-root-guide/

You've really helped get the ball rolling on this phone. Let it keep rolling I say...

You can use the 'System Update' app to do a system update from Over the Air or a zip file on the SD card. Currently, there is no update available for the dual core model. If one becomes available I'll be sure to post about it here.

Fairly sure it supports 3G over 900mHz. I've had 3G coverage over New Zealand networks on providers that only support 900.

Yep! There is a little LED next to the speaker. Blinks green when you have a new notification.

I just got this phone and I'm having trouble trying to connect it to ANY network. Did you have any issues with getting it to find any network? I'm not even looking to get 3g working. I'm in Canada, Bell network: UMTS/HSPA 850MHz and/or 1900MHz.

I'm putting my SIM card into the top slot correct?

Well after using the G2 for about a week now ,I must say I am dissapointed in the way the phones screen seems to resist scrolling through pages,especially going from the top of a web page to the bottom quickly.
It just does not happen quickly and you need to flick several times to get to the bottom.
It seems to resist doing this,I am use to flicking the screen and it moving lightning fast and fluently to the bottom of a page.
This is annoying enough for me to not use the phone any more.
