Personally, I had no problems with GPS. It locked in fairly quickly the first time, and very quickly each time after that.

I wonder if editing the GPS configuration to optimize it for different regions would help other people. I'm in Taiwan, so maybe that is why it worked well for me.
[Upgrading, Modifying and Unlocking] petymeg:
Thanks for your advice.

I prefer Snapdragon, but unfortunatelly low-end and medium performance dualsim phones are aviable with Snapdragon chipset. (the strongest dualsim phones equipped with MSM 8225+Adreno 203+768 MB RAM, that is a joke...) JY G2S is strong enough and its size is suitable for me.

I have now an Xperia S what is a good gadget but only single sim...

I still waiting for a better phone with Snapdragon and leaving out MTK chipset.

I am in Europe (Hungary) and many Hungarian G2S users are complaining about GPS... It is working but only with continuous mobilenet connetcion. It would not a problem in Hungary, but the mobile net fees in abroad... it is terrible.

Hi,

There is no hungarian language by default, and I have also did not found it in custom roms (avaliable on needrom).

Hi I am planning to flash Lewa myself. Did you use CWM to flash it?
[Upgrading, Modifying and Unlocking] fcsabika:
No. I used the Chinese Lewa recovery to flash it.
[Upgrading, Modifying and Unlocking] xaikman:
does lewa recovery have all the abilities of cwm? can it take full rom backup??
[Upgrading, Modifying and Unlocking] fcsabika:
Yes because Lewa recovery is a modified version of TWRP recovery. But it is chinese language only.
[Upgrading, Modifying and Unlocking] aladop:
Do you think you could write a short English "how to" on Lewa recovery? I am sure many others will appreciate it too.

Okay if I will have time for it in the weekend I will make it.

Is anyone happy with the gps? Especially anyone from Greece? It is of great importance to me. I use it everyday and I already ordered the phone by minideal. It will be of no use to me if gps doesn't work :(
[Upgrading, Modifying and Unlocking] StardustOne:
GPS works, but it takes quite a long time to get a satellite lock. There are a few tools that can be used to speed this up, yet it did not help too much in my case. I had the phone picking up the satellite lock in about 20 seconds but I also had siuations where it took about 3 or 5 minutes for a satellite lock. Plus, the phone saw about 12 satellites, but only used abou 4 to 5 to lock the satellites.

In general it works, yet it works better if you regularly update GPS data (the tool GPS status can help you to clear and download new GPS Xtra data to speed up the satellite lock process). Plus do not expect a good satellite lock with lots of clouds, but I assume that is the same with all phones.
[Upgrading, Modifying and Unlocking] arkas5:
Thanks for the feedback. Have you used navigation programs such as navigon or tomtom?

Hi,

how is it possible to improve the gps antenna with aluminium foil? Where should I put it?

[Upgrading, Modifying and Unlocking] k.geree:
I was about to ask the same... did anybody try to disassemble the phone and boost the GPS antenna somehow?

I've seen some pics/video for other phones, but not for this one ..

[Upgrading, Modifying and Unlocking] k.geree:
I just disassembled my G2S - just the cover and the plastic back which was secured with the 6 * screws.. Bended a bit the connectors of the gps antenna, right next to the volume control switches (I hope it was the GPS :) ) and put a 2 layers of aluminium foil to the connectors and routed it out to the back of the phone...I can't test it today, but will check tomorrow how it is working...
[Upgrading, Modifying and Unlocking] 1_Petje:
Well? How did it go, some improvements? Please upload some detailed pictures on the net. Can also someone who is experiencing the screen problem, make a video and put it on youtube or so..?

Thanks
[Upgrading, Modifying and Unlocking] twrock:
I just talked to someone at Jiayu about my replacement phone. They said that they couldn't send it directly back to me because of some sort of ban on direct shipment. So they have to send it to Shenjen first and then send it on from there. So probably another week! :(

All I can say is that the jump screen problem better be solved, or I am not going to be a very happy man.

is there any way to undervolt the phone already? theres an app called mtk cpu control in the play store but that only supports an older mediatek cpu..

After tweaking gps.conf I've achieved acceptable results, but still looks like low GPS satellite signal levels are the key problem to achieve a fast fix at all times.

Any solution?...

[Upgrading, Modifying and Unlocking] bazilio_lg:
OAUniva upon

Russian 4pda forum recommends not to touch the phone (literally!) during the flashing process - it is believed that during flash and first boot the touchscreen calibrates itself, and any incidental touches to the screen or its metal bezel may lead to miscalibration.

Yes, I tried with an L shaped aerial sticking out without the back cover.

[Upgrading, Modifying and Unlocking] twrock:
My own story is in the first post in this thread. No, nothing I did solved the problem, including putting the phone into the refrigerator prior to flashing the update rom and being extremely careful not to touch the screen. Nothing helped. I finally sent it back to Jiayu for replacement. My new phone is supposed to arrive this week. I can only hope the new one doesn't have any problems with this "jump screen" problem. It is very frustrating.

Jiayu G2S screen "SHAKE" problem

Hello again, talking about the screen "shake" problem :

Jiayu G2S screen "shake" problem, even after flashing Stock ROM G2s_20130109-104044 without touching the screen when flashing and rebooting...

[YOUTUBE]o_Jv_YbRqqM&feature[/YOUTUBE]
[Upgrading, Modifying and Unlocking] genkiz:
Same here. Screen shake and weak gps, drops signal after 2-3 mins.
[Upgrading, Modifying and Unlocking] miklos13:
So it seems, that the problem (unfortunately?) is not only the bad antenna/SNR.

Could you upload a photo with your additional atenna?
[Upgrading, Modifying and Unlocking] 1_Petje:
Tanks for the vid's n pic's, seems to me that is workable.. I'm still a non-touch screen user, but who is holding its finger for a longer time at one spot at the screen? normal use.

I've bought one, still waiting for it. I love the spec/size balans of the phone. Reading the chinese official jiayu forum makes me less confident. Those guys have a whole lot of problems, but don't rap about our GPS problems :p

hxxp://bbs.ejiayu.com/thread-395114-1-1.html

offcourse using google chrome translator :angel:
[Upgrading, Modifying and Unlocking] peron:
It was only a temporary antenna and I quickly removed it since it did not improve the user experience.

The SNR should be enough to have a decent GPS navigation but there seems to be a problem with the driver for the mt6628 chip.

It randomly loses signal without reason, like if there were interferences or mishandling of the data received or both.
[Upgrading, Modifying and Unlocking] twrock:
I am still waiting for my replacement phone. However, my first phone had no problem with GPS. Quick fix, not dropping, etc.

Is that because I am in Taiwan and using the same satellites as China? Are the GPS settings in this phone optimized for China and therefore don't work well in other locations? How does the AGPS effect this?

I don't have answers, just a number of questions. :confused:
[Upgrading, Modifying and Unlocking] trezor69:
Did you try this?

Adjust microphone settings in the phone

1 Install Mobileuncle MTK Tools (Google Play)

2º Enter in to Engineer Mode Menu (MTK)

3º Audio / Normal mode / Type / Mic / Level

4º Set up the 6 levels:

Level 0-255

Level 1 to 235

Level 2 to 215

Level 3 to 205

Level 4-195

Level 5 to 185

Level 6-175

* You have to set all levels to value. Every time you go to a level you must push Set and OK.

5º You must presh Ok again before exit app

6º Restart phone.

i have a similair problem, volume of the mic is very low.

Try to adjust it with editing it in the engineer mode but no change. Stays at level 0 after reboot

have a jiayu g2s of the new batch,with latest firmware and pre rooted

Maybe flashing with new/other firmware will help? & which modded fimlware should i install?

There is no official statement but it would seem that Jiayu released an official ROM update...

http://www.needrom.com/mobile/jiayu-g2s-12/

... with the following changelog

1. Increase equipment compatible with versions G2S

2. Increase the distance sensor calibration

3. Compatible with Samsung flash memory chip

After many attempts I was able to flash it on my device and surprise surprise the screen oddity well demonstrated in this video is back.

No improvements seen so far but I only flashed it minutes ago, will report back tomorrow.
[Upgrading, Modifying and Unlocking] JohnLaShot:
Hi.

Here is the official statement from Jiayu regarding the new G2S ROM from March 6th 2013.

Twrock, the english translational provided by google is not very precise. Is it possible that you give us precise information what is really meant by Jiayu's post? Especially which G2S device model is flashable with the new software version. As far as I understand the new ROM is not fully compatible with all devices.

Regards,

John

Hi,

just go to settings/accounta/add account, and choose 'corporate'. It worka for me.

M.
[Upgrading, Modifying and Unlocking] arkas5:
There is no "corporate" option under account. I have the official ROM. Do you by any chance use another ROM?
[Upgrading, Modifying and Unlocking] miklos13:
I am using the official ROM from january.

It is OK, that there is no Corporate under account, until you have not created it. First you have to go to system settings/account/add account (last option, under the already created accounts). When you click add acount, you will be able to choose corporate.

Ther is another way too. Open "Email" app (not gmail!) tap the menu/settings. In the right up corner you will find "add account". Tap it, and follow the wizzard. On the second screen you will be able to choose from pop3/imap/exchange.
[Upgrading, Modifying and Unlocking] IvanX9:
You have another good option, use an email client like "K9" ( you can find it in Google Play)

That is the problem. I have no "Email" app under "add account". I only have the google option :confused:. I am using January 8th ROM. Isn't it strange? My phone arrived last week from minideal.net.

what rom came your phone with? latest official 20130306-143807?

mine came with 20130109-104044 and i never had that jump screen issue. but once i flashed 20130109-104044 the screen was juming all over the place. I flashed back and forth a couple of times and the older soft has always been fine, although i've got a screen protetor on it, but the newer has never been calm. I belive all that stuff about not touching the screen on first boot is quite a bull

also what is the best patch to reduce that red LED bug, after which the cpu would not go into deep sleep?

from what i understand from google translator, the russian patch would only turn on the LED if the battery is at 1% but what does the spanish do?
