OK, got it now :) Think I'm being a bit sloooooooow lately.

I've been messing with GPS again today, going over all the tips I picked up before I even purchased the Jiayu and nothing really helps, especially over time and after a few reboots. Actually, I haven't changed the JIT to fast yet as Mite recommended and I haven't tried enabling 'intermediate position' in the GPS config yet, but I'm pretty sure I've tried most other combinations of agps, epo and GPS config tweaks from a number of sources. Lol. Waste of time.

Just stumbled upon this info regarding tweaking the GPS config file if anyone is interested.
[Device Reviews and Information] kambingbakar:
Could you give a tutorial how to do it or is there a "cwm zip" that can be used to do so?

Tx
[Device Reviews and Information] Doman:
OK, have a time for just a quick one :) If anyone requires more detailed one please ask, I'll do that later on.

1. MAKE A BACKUP OF YOUR FILES, AS IT IS VERY LIKELY YOU WILL NEED TO FORMAT MEMORY OR MAKE FACTORY RESET!!

2. Install MTK6592 drivers, so that it can be use with SP Flash Tool:

- drivers: http://ge.tt/16RpEaG1/v/0?c (if not available try to Google "All MTK Driver 2014")

- quick tutorial (only if you have problem with driver installation): http://droidchina.com/forum/Thread-How-to-install-MTK-USB-driver-manually-on-Windows

3. Download SP Flash Tool.

4. Prepare 3 files:

- scatter file (can be taken from the firmware archive (http://www.needrom.com/phone-roms/jiayu/g4s/)

- EBR1 and EBR2 file (depending on what memory split do you want

ONLY FOR 16GB ROM GS4!!! (Internal Memory / Phone Memory)

- 7GB/6GB: http://www.4shared.com/zip/RehW_ehpce/Ebr-7gb-mtk6592.html

- 10GB/3GB: http://www.4shared.com/zip/FKP0Mn4yba/Ebr-10gb-mtk6592.html

- 13GB/~60MB: http://www.4shared.com/zip/tG3PUmihce/ebr_1349_zp998.html
​

5. Flash procedure:

- power off the phone

- remove the battery, put it back, but do not turn on the phone or connect to the PC

- open SP Flash Tool

- select scatter file, EBR1 and EBR2 (if you have the whole firmware unselect the other positions in SPFT, so that only EBR1&EBR2 are being flashed)

- select Download on the SP Flash Tool

- connect the phone to a PC via USB cable

- if flash is OK reboot the phone

- it might be necessary to format phone memory or make factory reset

I've done some more GPS tests as well and I must admit, that this awfully looking wire-mod actually works:

http://en.miui.com/forum.php?mod=viewthread&tid=10317&page=164#pid471584

I'm still waiting for a copper tape I've ordered, but I've found some other, thinner copper wire. The best results I get with a wire sticking strait to the sky. If I bend it along with the phone the signal get worse. Putting it under the back cover basically destroys the whole mod effect :(

So here is my observations:

- wire antenna sticking out of the phone up to the sky: flawless signal and navigation (finally my position indicator is exactly on the street I drive on Google Maps!!)

- wire antenna sticking to the ground (along with the phone): a little worse signal and but should be enough for navigation

- wire antenna hidden behind the back cover: signal is too weak for navigation, positioning error is too big

- no wire-mod: weakest signal, although the phone sees satellites and get fix, the positioning error is too big for navigation

I attach some proofs. Guess which one is with antenna wire-mod ;) The second screen shoot has been take just a few seconds later after removing the wire from the phone. The satellite signal has dropped on the eyes.

I wonder one more thing. I've played with this mod yesterday. Next to the Jiayu I had Samsung S4 Mini and Samsung Xcover2. Regardless of SNR, time to fix and satellites "in use", both Samsung phones had more satellites "in view" all the time. Jiayu had 13 to 16, while Samsungs 20-25, so the difference was noticeable. Is it because the better antennas or is it something that you can define in software?
[Device Reviews and Information] pozzeco:
I think it's because of Glonass
[Device Reviews and Information] Ouzo:
This is what mine looks like standing by my house. I'm getting a much better signal without any modifications. Are you in a city with a lot of buildings around you? If not I think your antenna may have an issue.

I agree with pozecco.....Samsung devices use the glonass satellite system too now. My Note 2 was the same.
[Device Reviews and Information] Doman:
Definitely no city and no high buildings. I've made the test on my way to work. Some open area, some trees, some small buildings... there is no significant difference for the signal.

Your GPS Test looks good enough for navi. What I've read is that SNR should be at least 30-40 for Google Maps as example. And that is what I've noticed as well. Below there numbers Google Maps goes crazy.

Mine looks like it is missing the GPS antenna at all :D But it is strange that I'm not the only one with such problems.
[Device Reviews and Information] mite_jan:
what app does not give you good a good accuracy

i may try IGO prime navigation with the latest offline maps on street level to see if there is a problem
[Device Reviews and Information] Alex1a:
My GPS was nearly unusable since I have my G4S. Today I opened the back cover and pressed a finger on the GPS antenna. Immediately I got a fix with lots of satellites and 2m accuracy! And that persisted after closing the cover. Now I still get quick fixes with good accuracy even inside a house, which was never possible before... I still have to test this more, but maybe others with bad GPS could try that, too.

Maybe those other successful antenna experiments just work because they press the antenna while attaching the adhesive tape :)
[Device Reviews and Information] Doman:
mite_jan

Mostly with Google Maps. I have a Sygic as well, but I use it mostly abroad. Sygic seems to work better, but I need Google Maps :) I use it localy as it shows me the traffic and have a huge database of POIs, shops, companies, etc.

maf-soft

That's something new. I was curious and opened the phone, but there is nothing to be pressed :) The antenna seems to fit well and do not move.
[Device Reviews and Information] mite_jan:
This happened becouse when you pressed your finger the gps got your location and now when you are trying to locate it again it remembers it. This can dissappear after some times or after your first start

I dont havea 3g connection to test this
[Device Reviews and Information] Alex1a:
No, I was on my bike and the very good reception stayed until I arrived at home. And there it continued inside the house, which I had only with other phones before.

My anntenna also didn't move when I pressed it. I don't know what caused the change. I need to do more tests, but what I saw yesterday was really a surprise.
[Device Reviews and Information] Ouzo:
The part of the antenna you see is just metal tape with a self adhesive backing. Somewhere underneath the plastic shell it will make contact with the main board. In general, if you use a hairdryer/heat gun you can gently pry up the antenna at the top and bottom ofthe phone, then undo the eight screws and remove the back cover, carefully passing the antenna back through the slots in the cover. I've seen it done on another phone on YouTube, but it looked like it would be very easy to damage the antenna. My guess is that when you pressed the back you applied enough pressure to make a better contact with the main board.

Sorry, I just realised it doesn't look like there is a slot to pass the antenna through....
[Device Reviews and Information] Peppiie:
I'm sorry if these questions have allready been answered, but can someone plz confirm if the jiayu G4S is prerooted and most importanly does it work with whatsapp? thanks in advance
[Device Reviews and Information] Ouzo:
The answer to part of your question is in the opening post, but yes, the official firmware is pre-rooted. This can be turned on and off under settings/security.

Mixed reports about WhatsApp...
[Device Reviews and Information] Peppiie:
thanks, yeah I've read the opening, but i was a bit cautious about believing it because this is the first place that I read that it's indeed pre-rooted and that perhaps I missed an important detail about it.

Only if its not to much to ask, can you chek on you own device if whatsapp is working? assuming you've got an G4S
[Device Reviews and Information] Ouzo:
Um, yes, I have a G4S.

Sorry, I just don't use WhatsApp.

The ROMs on many of these MT6592 phones are basically the same, including the bugs.
[Device Reviews and Information] Peppiie:
Well thanks anyway, this topic has provided me with allot of information that I've yet failed to find elsewhere. :good:
[Device Reviews and Information] Doman:
Whatsapp does work for me. the only problem I find now with G4S is the GPS antenna.
[Device Reviews and Information] Ouzo:
You're welcome. I'm sure one of the other guys will chip in about Whatsapp.

Check MTKForums for more info. Also try the comments section attached to each ROM listing on NeedROM.
[Device Reviews and Information] vladata:
hi, does everyone knows if in G4S the 2 SIM cards are active at the same time? because i had i situation today, i was talking from first SIM card with a friend and another one was calling me ot the other SIM card but no response and no indication or sound notify me about that. I was told that the 2 SIM card are active at the same time.
[Device Reviews and Information] Ouzo:
I've just done a very quick test and indeed there does appear to be a problem. My girlfriend rang on one on number (the one which does not have 3G allotted to it), then I used a spare phone to ring my other SIM. I didn't get any notification on my Jiayu and I didn't hear anything on the other phone I was dialing from, it just went to voicemail. For info, the SIMs in my Jiayu are on different networks.

Having said the above, I know the G4S didn't support dual active SIMs, only dual standby, but in truth as this is my first dual SIM device I don't fully understand the implications of that when you're making a call and someone else rings you.
[Device Reviews and Information] indiffereddie:
Whatsapp does work without any problems in stock rom.

I still didn't find any information if this is a dual band or a quad band phone :(

[Device Reviews and Information] chalimoja:
WhatsApp works fine on the G4S on all ROMs that I have used so far. and yes the phone is dual standby not dual active so when someone call you on the other line you will be unreachable until you finish your call. That why I deactivated the call waiting option on my sim cards ever since I started using mediatek dual sim phones.
[Device Reviews and Information] Doman:
Most of the dual sim phones are dual standby... I do not understand why are you surprised :)

Hi all, anyone able to fix the resetting battery stats after reboot? I know its not a big bug but i hate it when i need to reboot the phone (due to xposed moduls etc.) and afterwards the stats are empty. Thanks for any hints

[Device Reviews and Information] Ouzo:
I had a ROM on an old phone that had the same bug (feature?). A dev fixed it but I don't know how. Do a wider search on XDA for the answer, there'll be something on it.

I'm searching now but I'm not getting very far with an answer...
[Device Reviews and Information] kambingbakar:
Thank you very much for the tutorial.

I have been using 13G/60mb configuration but unfortunately although it has been in set to using internal and sd card the system still write to phone storage.

Screenshot and application cached especially do this. My temporary solution is to use 10 gigabytes configuration and using folder mount app in some folders in the phone storage.

Is there a way so that the system can do all the writing to internal memory without using the phone storage at all like other phones?

Thx in advanced..
[Device Reviews and Information] Doman:
I had the same issue. What I did is I swapped mounting points of Phone Storage and SD Card. After that I unmounted the Phone Storage completely..

At the moment I have only Internal Memory and SD Card, but acting and seen by the phone as Phone Memory. So the Default write disk is Phone storage, but the real path of it is SD Card.
[Device Reviews and Information] kambingbakar:
Tq.. i believe that would be a solution for now.
[Device Reviews and Information] indiffereddie:
I can confirm that people are having problems while talking to me cause they hear their own echo, although I don't have any problems with the sound. Is there any way to fix this so far?

Are you in a noisy environment when this happens? So far my callers haven't experienced this problem, but I'm usually in a quiet place when I make calls. I wonder if it's something to do with the noise cancellation microphone on the back.

This is interesting if true...

I can confirm that a comparison between my G4S my HTC Sensation show a 1 hour discrepancy. Screenshots attached. The one with the notification bar visible is my Sensation which shows the correct time.
[Device Reviews and Information] Doman:
Hmm... I've noticed it myself a few days ago. I was surprised but had no idea it might matter, so didn't really bother to look for a solution. I thought it some phone or application settings that cause the difference.
[Device Reviews and Information] Ouzo:
I don't know enough about how GPS time signals work to know if it is a problem, but it seems to make sense. I wonder if an exposed module could intercept information from the SoC at a low level and pass on the corrected figure to any app that uses GPS.

I'll start googling to see if other devices and chipsets have had similar problem.

Gents, in another german forum we noticed an app integrated into the rom which is creating a positive alarm at anti virus malware scanners, the app is called lovely fonts. I uploaded the apk

Can someome with the needed knowledge check the apk and see what it does? Its implement in all stock roms since 0609 (needrom, jiayu.es), i deleted the app from my system as of now, would be happy to get any info from a dev or anyone with rhe knowledge as the file as per avg virus is malware which calls home

I think the release notes on NeedROM did say something about a font manager, BUT, it has a lot of permissions so if it were malicious it does look like it could download and install packages if it wanted.

As I'm not a developer I find it so difficult to know what to do in situations like this, especially as Jiayu don't release their ROMs from an international English (French/German/Italian/Spansish etc) website. These ROMs could have anything cooked into them. Jiayu should employ someone with good language skills and create an English (or whatever) page on their website to formally release updates.

I guess it wouldn't hurt to remove the apk to be on the safe side. I'm guessing you haven't experienced any problems since you deleted it?

If you want, you can always download ROMs to your PC first and use this tool to extract apks from the system image and examine them http://xdaforums.com/showthread.php?t=1921399. I've used it already to compare changes between ROMs since I got my G4S.

I guess you could use a file explorer to put the apk back, then set the appropriate permissions on it, then reboot with WiFi/data off and see what happens to the option in settings.

"fonts" version 6.26, icon white background with big black A and a lower-case a in superscript

I wonder if you all check existence of this app in various ROMs only by it's name com.lovelyfonts, or if you really compare a checksum. It could be a legit app, and some trojan just uses it's name.

I have it too, in my recently installed 0609 from here:

https://mega.co.nz/#!M8YjCZhC!R2h_61PJ7n9THWTyeAIe7HtTkIJN8s5dTbnDoG3f00c

This ROM first started up russian and has gravitybox and some Xperia keyboard pre-installed. It works very well.

Tonight, I had data and wifi disabled and this app com.lovelyfonts caused over 90 wakelocks according to WLD. I see it has a lot of rights and can do everything. That all doesn't make sense for a font manager?

Do you guys want me to check something else about it?
[Device Reviews and Information] Alex1a:
Can you upload the apk to www.virustotal.com? I don't know how to access this file and also I'm very busy.

Under file detail you can see a lot of information about what rights it has and what it really does (see example in my post above, I edited it multiple times, if necessary read it again)
