I don't know about the second batch, because I have not see anything on the web that makes it clear the problem is truly solved. Maybe it is, but I don't know. I have to wait for some time before I get a replacement phone as well.

What I want to see is a very clear statement from Jiayu that they know exactly what the problem with the jump screen was, and they have changed something about the manufacturing process so that it will not be a problem in any of the newer G2S phones. Obviously the software fix that they released did not work for everyone (me included). So when they try to tell us that they have fixed the problem with a new rom, I don't believe them. I know the new rom does

not

solve the problem for my phone.

My GPS is very accurate and very quick (few seconds) to lock in to the satellites. My first use took more time, less than two minutes. But after that, it connects quickly and accurately.

I have only taken pictures, no videos. Pictures are all fine. No problem for me at all with pictures.

The metal ring all around the edge makes it a very solid feeling phone. With the back off, you can see that the metal is quite thick as well. so it is not just "sheet metal". I don't know about the G3.

Jiayu 20130109 patch

Just to post a positive also, I had the jumping screen problem on my G2S. Even with it it was fully usable for me, just a bit unnerving. I applied the 20130109 patch from the Jiayu forum and the phone works just great now, before it was nice, now it's great. I didn't even put the phone in the refridgerator neither did I remove the screenguard, just cleaned the screen before flashing via sd-card.

By the way, the forum says clearly, that you shouldn't apply the update if you don't have the jumping screen problem...

Bluetooth GPS problem

Hi,

I wanted to solve GPS problem by buying external bluetooth GPS: I used lots of apps but I have problem, that when I connect to external GPS, it stops to work within a minute. Then I have to restart app and connect it again.

Anyone knows how this can be solved, please?

And anyone have any video/photo tutorial, how to improve the internal GPS antena? I read the whole forum, but I found no detailed instructions.

Thank you very much.

replacing the buzzer will probably fix it.. i had the same problem, didn't even buy an orginal replacement but used the speaker of an old nokia phone. works fine..
[Upgrading, Modifying and Unlocking] kkenpachi:
The external speaker is attached to the plastic cover held by the 6 screws and isn't fixed to the phone.. the speaker contacts make contact with the pressure, when the phone is dropped or is not aligned the contacts are off ,

put a song to play remove the battery cover and press in the speaker area "low left" if working then its contact problem you must remove the 6 screws and try to fix it

I have removed the speaker off the plastic cover and had taped directly on the phone now works fine

Hi!

I have a G2S, i like it very much. Unfortunately I also have a lot of problem with gps. I've tried a diy antenne, but it's still worse. Could anyone recommend me something to fix the gps?

(Yeah, a bit weird responding to my own post, but I thought I'd follow up with my experience....)

I did install the Jiayu.ES_mod_signed_CWMG2S-20130907-000001 rom on my "original" phone hardware from early January. Everything appeared to work well, but I only used it for about 30 minutes before restoring my previous rom. (I had work to do, and needed my phone.)

Regarding my GPS, I did sit outside on a clear night tonight and waited for a GPS fix. It took about 6.5 minutes, but it finally locked. I then walked home and it seemed to track quite well, until I walked into an alley with high buildings on each side. I wonder if future locks will be quicker, now that it locked on once.

Despite the apparent GPS problems, I'm considering buying this phone, but I would like to know if it supports OTG?

If not, what other 4 inch phones for under $200 have dual SIMs and supports OTG. I've already spent hours looking and asking, but no help so far.

spare part GPS antenna

Antelife sells Jiayu G2S GPS antenna separately:

w w w. antelife.com/original-gps-antenna-for-jiayu-g2s.html

Can someone check whether this could be an improved version of the one compared to the one our phones came with?

Thanks.
[Upgrading, Modifying and Unlocking] twrock:
I don't know why there would be any improvement. If it is the original antenna, it should have the same results.

Since my phone is almost a year old (almost done with the warranty), I did mess around with my antenna a bit. I only attempted to put a piece of tape on one connector pin (it has two connector pins) to test if it helps to remove the "short" between the connector pins. I saw no improvement. YMMV, but I think I'll just give up on the GPS of this phone (and not buy Jiayu products in the future).

There were two minor bugs. First issue I had is with the notification led. At first message it starts to blink red ,but when clearing it stops working. It's not a problem because I've installed an app from play (Light Manager) which do the job even better. The second is that the Xperia keyboard included in this rom force closed ,so I deleted it. But since I use the AOSP keyboard (also included) it is not a real issue for me. Otherwise I have no issue with it. I didn't make a 'clean' install ,ie. I kept the old data partition. There were only one or two apps wich had to be reinstalled.

I've installed a new antenna from here and it is working a lot better than anything I've tried until now. The only difference that it is white not blach as on the picture. (I've tried wires ,copper foils of different shapes and sizes)
[Upgrading, Modifying and Unlocking] bazilio_lg:
This is the usual original antenna.

Maybe it improved your GPS reception only because your original original antenna that came with the phone had a loose contact in the first place. By installing another you might have fixed this.

I've made a GPS antenna from aluminium kitchen foil just like the copper one that is shown on the previous page.

It improves reception a bit. Later I've found that if I take the back cover off, GPS reception instantly becomes very good:

- accuracy 5-6m

- 10-14 satellites visible

- signal levels jump up to 40-45

- walk speed starts showing (instead of staying at 0 km/h up to real ~20 km/h)

But when I put the back cover on the phone - voila, signal levels low, only ~6 sats visible, accuracy 30-40m. Looks like Jiayu made black soft-touch back cover out of some adamantite :mad:
[Upgrading, Modifying and Unlocking] iimre:
May be ,but what I've received is white so it is probably some kind of third party make.

Wifi dead or zombie

Hi, my problem isn't related to week WiFi signal, but with the WiFi activation itself. I've realized that there other equipments with similar behaviour. I've tried already a lot of things: Flash Rom (several times), factory reset, clear cache... I'm afraid that could be an hardware issue, but the strange thing is that either Bluetooth and GPS are working properly and from what I've been searching the chip responsible for bluetooth is the same for WiFi. I've also breaked the warranty seal and open the phone, and the most of times WiFi worked ok (opened)!! weird...!!! everytime I closed it WiFi quit working...

The current status is that my Wifi is like a "zombie" it could work for 20min a day, then the icon is always "filling".

In the logCat I get errors on the WiFiStateMachine saying "wlan[0] could not load driver... can't connect to supplicant...

If someone could help me somehow, I would be very thankfull...

Thanks.

Fellow G2s users that have issues with red LED blinking (and thus no Deep Sleep), there might be some help.

There is an app LED Notifier Off that disables notification LED on other phones. But on G2s it only disables the blinking!

LED continues to light up (all 3 colours work as they should), but CPU sleeps well.

For example - when recent version of Viber fires up a red LED incoming message notification, CPU goes into Deep Sleep mode normally.

It's a very easy phone to work on, pull all the screws out of the back, pull the back off, unplug the boards and camera etc. Use heat gun to warm edge of broken glass, gently lift glass off, careful not to cut yourself, glass is not attached to the LCD so don't overheat it and ruin the LCD. If you're careful, you may be able to reuse the two sided tape. Otherwise you'll need 1mm 2 sided tape to glue glass back in.

Just some information for those who are still using this phone, but whose battery is now getting weak. Etotalk.com has G2/G2S battery on sale for $9.99 free shipping: http://www.etotalk.com/original-battery-for-jiayu-g2-g2s_p3532.html

It is listed as "Original Battery for Jiayu G2 G2S", but only 2050 mAh. That must be what the G2 had for a battery. Still, if it is an "original Jiayu battery", maybe it will extend the life of these phones.
[Upgrading, Modifying and Unlocking] papa-nundo:
To my knowledge the battery for G2F can be used with G2S, as well. And this one should be easy to get.

After many emails of "excuses" and misinformation from Etotalk, and after waiting for over a month, I was finally told that my money would be refunded and the order cancelled. Etotalk says that they can't ship batteries, but they still show that battery for sale. But now it is double the price and still offers "free shipping". I don't care how cheap it is and how "free" the shipping is. If they aren't just playing more games with me, it doesn't matter if you try to buy it, because supposedly they can't even ship it! :mad:

I was frustrated with Etotalk when I bought the phone. They were very hard to work with when my phone needed to be returned under warranty. Actually, they were no help at all! I had to have a friend help me deal directly with Jiayu to get the phone repaired. Now they took my money, kept stringing me along, and finally refunded my purchase, even though they still show the item for sale! I do

not

recommend Etotalk to anyone; look for another seller if you want to purchase online.

Edit: I ordered a battery from Banggood.com. I'll see if they can do better than Etotalk.

Hello, firstly I apologize for my English. I have a Chinese phone Jiayu G2S for over a year, but since few months touchscreen isn't working well.

I was wondering what might be the problem and I thought about my hot baths in a tub with surfing the net. Maybe because of that, moisure get inside a phone?

Hard Resetting Jiayu G2F

Hi There,

My question is related to Jiayu-G2F. I realize this is not the same as G2S, but was told I can try to post here.

I bought my device from China about a month ago and tried to replace its original Chinese Rom. Probably due to bad Rom, the phone was bricked.

I found an excellent video tutorial on how to unbrick Chinese models, which I recommend everyone in a similar situation to watch.

I was not able to paste the link here, so if you want to watch this search "unbrick itxtutor" on Youtube.com. It's about 22 mins long.

However I am having trouble trouble getting past one of the stages, and that is putting the phone into META mode using either physical buttons (Vol Rocker + Power button combinations) or even touching the test points on the PCB (as shown on this video).

I would appreciate it if anyone who had been lucky in reviving a bricked Jiayu-G2F could share his experience.

Also, if someone knows what is the right button combination to get into META mode that could help too.
[Upgrading, Modifying and Unlocking] V-incent:
you enter the standard recovery volume button down + power button.

i didn't brick mine, but how much of your phone is still working?
