• Answer to the question "which version of the phone to choose?"- WCDMA (3G) version! (And for Ukraine too!) Or read the first and other posts of this topic. It was discussed many times. HD resolution in the TD-SCDMA screen is an imaginary marketing move.
  
• In the screen TD-SCDMA version Jiayu G2Fis usedPenTile subpixel layout. (Macro screen by users:1, 2, 3, 4. VisualcomparisonJiayu G2F screen with a screen of the usual structure.) According to users, the grain is visible to the naked eye, but does not interfere with visual perception.
  
  About charge and battery:
  
• How much of a smartphone’s battery charge lasts depends on: the mode of operation, which functions, how often they are used; from the firmware version of the smartphone; from installed applications; the level of the mobile network signal in your area; on ambient temperature, etc. How much the smartphone will work for you, you can only determine yourself. The topic has user reviews:1, 2, 3, 4, 5, 6, 7, 8, 9, 10etc. +battery information.
  
• For many owners, the new Jiayu G2F can work for a long time with battery readings1%. During operation, the readings gradually begin to correspond to reality:1, 2, 3, 4. Those interested can trycalibrate the battery.
  
• Battery full charge time -about 4.5 hours.
  
• Coming with a Jiayu G2F charger during charging can cause strong interference with your smartphone. The touch screen mistakenly identifies clicks (phantom clicks). In this case, you need to replace the charger with a better one.

6582 video - Mali 450MP2 (6588 and 6592 will have 450MP4)
According to Wikipedia, 450РњР 2 is approximately at the level of 400РњР 4, a bit faster. frequency is higher, like geom speed doubled.
Those. - this is the level of Galaxy C2 / C3, not bad :)
But with standards support - OpenGL ES2.0 and that's it ... no OpenCL :(

And there is an open source driver -http://limadriver.org

[Slonyarka]

Only he has Mali400MP2,16Flops somewhere, a little less than sgs2

[314rat]

for $ 82 I'm ready to take 20 of these pieces, with the following characteristics: tablet_za:

[Alaska14]

interesting weight of the device, it has a metal chassis that does not make it easy. If there is 150 grams, I will look towards the Ski, although it is three times more expensive ...

[kotvmeshke008]

314rat @ 10.29.2013, 14:47

for $ 82, I am ready to take such 20 pieces, with such characteristics

Such a price - the usual rule of Jay - to pull time and reduce the estimated price by several times, and at the time of issue they will cut supplies and give them to the “willing” for a fortune! So the price will be about 220 dollars.

[realGRom]

Kotvmeshke008 @ 10/30/2013, 16:31

Such a price is the usual rule of Jay.

I agree. So it was with the G4.

[Grisard]

Stop, chew 4 can be at a price of 220 bucks to take. Edge price tag 150 bucks. Well, maybe the first two months of 170 pozagibayut

[aml86]

On Ali, pre-order for G2F from $ 149 and higher began. Some sold point out that the IPS matrix. I want to believe, because with the thickness and the battery is similar to the G2S (9.9mm / 2200mAh), the latter simply does not fit.

P.S. Officialforumalso indicates in the characteristics that there will be IPS.

Only in real sale to wait for him in three months. They are half a year ago, the announced G5 just started selling. And they made the first batch of blacks, but there are no whites yet, and they will only be in mid-late November. So with this expectation before the disappearance of relevance can be assumed.

Most likely, it will appear as it was written in late November - December, the only question is when it will be with a normal 3g.
As for g5, it is not necessary to design a model so much and to rivet in the model editor, the fact that it was announced does not mean that on the same day they started working on it. The policy they have such a make early stuffing.
But over such global projects, yes, they are swinging for a long time, but for example, G3S was announced and launched very quickly, and there was no problem to buy it, because it was an upgrade, just like this G2F

[ZiggiP]

As they say on the site, the devices have already been internally tested and transferred to ligushatniki (Lewa OS) to finish the firmware under the body (officially it will be left). The variant with WCDMA doesn’t cause any difficulties in manufacturing, the question is again in the license, and this is done as usual, not quickly (remembering the same G4). If we have done the work on errors and have already obtained a license, then we will probably see both versions in December ... In any case, it’s up to the frogs yet, how fast the firmware will be attacked ... In the meantime, the zhuzhi calves - on November 5, the direct competitor goes on sale (as the media see it) - “red rice” (Xiaomi Red Rice) with WCDMA and bite a good piece of the market;)

Well, in terms of size, it is not a competitor at all, but in the subject it is precisely this that is the most attractive, well, and the difference of 50 bucks between them. : nea:

Yeah, another percent, the size is smaller, but for some reason they rivet it on a competitor ... In any case, I’m waiting for it, but against the background of rice, the desire to take rice quickly creeps in ... if the price tag is up to 160.

Also the price is very tasty! I hate shovels, and here the diagonal is 4.3, which is very rare in the current trend for gigantism: P

And I would wait, look, what shoals the Chinese were ridiculous in this smart. After the release of g4, the topic was full of complaints. I do not think that they have made everything better on a cheaper model.
