bluetooth works great for me...i do work at a car renting service and whenever i do have to drive a car to a customer, i connect my phone via BT to listen to my music.

tested on 5-6 different cars and it worked without any problems...even when i got out of the car for checking the oil, it was still connected to the car audio system...

im on kitkat aosp team force rom just to mention...
[Device Reviews and Information] Ouzo:
I've read about problems with compatibility between android devices and some car head units many times now (with other devices, not the Jiayu). If you widen your search here on XDA for car stereos i think you might find some information.

The only thing I've noticed with Bluetooth on the Jiayu is that there are problems when WiFi is on at the same time. For example, the other day I was mirroring my screen to a TV wirelessly which worked very well until I have connected my Moga Pro controller via Bluetooth. The controller caused multiple iinterruptions in the signal.

Turning WiFi on when using A2DP seems to cause Bluetooth devices to disconnect. I use an MW600 and sometimes it works flawlessly, sometimes it just disconnects or the buttons stop working.
[Device Reviews and Information] Ouzo:
Yeah, the range of Bluetooth is one thing that is definitely great. Much better than my Tegra Note tablet, HTC Sensation or Note 2. A couple of times I've left my phone in the garage then walked in the house using my MW600 and the music plays fine and I completely forget where I've left the phone!

Bad GPS.. You mean slow..? The screen broke? Strange, since it has gorilla glass.. Did it fell from a tower..?

My 1s screen got damaged too even though it's said it had gorilla glass and it never fell badly. Only after weeks. Pissed off!
[Device Reviews and Information] Ouzo:
You must have introduced an error in the build.prop somewhere.

You can either do a factory reset, or if you still have root enabled, you can connect your phone to a PC and use ADB to push a backup of your build.prop to the phone (you made a backup, right).

Finally, the phone number fix doesn't work. I did post that it wasn't working on our Jiayu.
[Device Reviews and Information] Alex1a:
It fell down only 40cm from my knee, while I was sitting. See pictures behind the link.

Maybe it was very bad luck, or the glass isnt gorilla. It is very thin.

What bad GPS means, you can read all over this thread. Sometimes very slow, sometimes very inaccurate, even though it says accuracy 7m, it is 50m off. Sometime no fix at all. Sometimes acceptable.
[Device Reviews and Information] Ouzo:
There's quite a lot of hype about Gorilla glass that is unjustified. As you say, the glass is very thin so if you are unlucky you can break it very easily indeed. Countless Galaxy S4 owners will latest to this.

Yep, today GPS let me down very badly indeed, first refusing to get a fix at all to begin with, and then being next to useless in Co-pilot because it kept insisting I was on a road 50m from my actual location. Very annoying.
[Device Reviews and Information] GoJo ^^:
My Galaxy SII fell badly hundreds of times and screen's still perfect..
[Device Reviews and Information] Ouzo:
The S2 has a massive bezel around the screen though, and the screen assembly is thicker ;)

The alcatel of my wife fell 3m on stone and nothing happened.

Guys, just dont drop your phone [emoji6],

Gorilla glass is harder than normal glass, so it cab resist against scratches, on the other hand due to the fact that its harder it crashes easier as it is less flexibel in its structure. So wrong force from the side just burst it into thousand pieces. Thats the turndown of gorilla glass
[Device Reviews and Information] GoJo ^^:
On YouTube it's hammered and all OK though..
[Device Reviews and Information] but-888-:
Not seen the video, but i guess from thr front. Thats what i am saying. Its designed for a specific task. And unfortunately thats not falling onto the edge. If phone would have dropped face down, nothing would have happened. I know it sounds strange but that's material. Same as a bulletproof vest, shoot at it all good, stab it with a knife no protection at all

Bootloop

Hi,

I installed xposed installer and the framework on my jiayu g4s (stock rom 4.2.2) and rebooted the phone.

Now it is stuck on the bootlogo :(:(:(

Can someone help me? thanks !

That's why I use silicone cases. It always gives some protection and absorbs the energy when the phone meets the floor :) Mine has fallen straight on the edge hitting the pavement and there is no scratch on the phone, only on the case.

FULL Backup

Hi everyone!

My phone is here, pandawill shipped it really fast! Now I'm trying to do backup, and from what I've read MTK Droid Tools is preffered way to do it. Only thing is - every site I try says "MtkDroidTools_v253.exe is malicious" when I download the installation. Is this normal? Is this safe? Chrome blocks it, and Trend Micro deletes it from my HDD. I know it could be false positive, but wanted to check with you guys as you've got more experience.

Also, when I get MTK Droid Tools running, I need to backup:

under "phone information": IMEI & NVRAM

under "root, backup, recovery": Backup (button) + Backup userdata and cache (checkbox checked)

- is that it? or is there anything else?

Should I do a second backup of IMEI with MTK Mobileuncle Tools or Jiayu.es app?

Should I do a second full backup with SP Flash Tools just in case, or is this all the same in the end...?

EDIT: Nevermind, turned off antivirus, installed and used MTK Droid Tools to do NVRAM/IMEI backup as well as full system backup, also installed CWM with it and than did another recovery through CWM (all as written in these instructions: http://xdaforums.com/showthread.php?t=2730031 ), and backed up IMEI with both Jiayu.es app and MTK Mobileuncle Tools. Safe is safe. Now I can play with the phone...

Btw, I did not do a backup with SP Flash Tools, but I've converted MTKDroidTools backup to be FlashTools compatible, so that should do I hope... Actually, I hope I'll never use these files in my life :)
[Device Reviews and Information] Doman:
I've found a new 4.2.2 ROM. It is not that new, but I haven't met it before.

This is a ROM made by Jiayu Poland. It is a official one, but cleaned from Chinese apps, keyboards, troyans, etc. A very nice multi language stock ROM, that you can use "out of the box".

It also gives me great results with GPS. So far the best GPS experience at G4S for me at the moment. More details in a different topic:

http://xdaforums.com/showpost.php?p=54978616&postcount=11

The ROM is labeled G4SW 20140609-150354 and designed for Jiayu G4S 2GB/16GB:

How much of RAM left after booting this rom (same question for original rom)?
[Device Reviews and Information] dgal:
Does any of you have a problem with pairing Jiayu G4S with car audio kit? I am entering the pin on my telephone and afterwards car systems shows message atuhentification failed. Pin is correct (as I can set it up by myself in audio options in car)

I am using G4S with Kitkat ROM from Team Force and cannot pair device with my Kia Sportage audio. Will try to reflash it with JB ROM to see if it helps, but before will do it want to check as maybe some of you have the same problem.

Thanks
[Device Reviews and Information] Ouzo:
I had a similar problem with my Bluetooth keyboard the other day, even though I had already paired it a couple of weeks ago. My Moga Pro has also stopped working in HID mode. After I couldn't reconnect, I tried to pair again from scratch and now it simply will not pair at all. I think Bluetooth is a bit flaky over time. In on the stock Jelly Bean ROM from April.

Have you tried rebooting and beginning the pairing process again?

Could someboby tell me how to get original nvram 4.4.2 for my Jiayu G4S, cose when i change rom Ialways get problems with" com.android stop" AND I CAN'T ACCESS MY SIM TOOLBOX.

I don't remenber where i put my backup, only have the imei backup from mobile uncle.

Thank's in advance:good:
[Device Reviews and Information] Ouzo:
Did you make the IMEI backup when you were running 4.2 Jelly Bean? If so I think you might need to reflash the stock Jelly Bean ROM using spflashtools and then use Uncle to restore your IMEI. I'm not sure about this though, so please wait until someone else replies.
[Device Reviews and Information] but-888-:
Flash stock JB with sp flash should solve, if not you bricked your phone if you cant find the backup

Dual batteries

Hey people!

I got my second battery yesterday, but I've got interesting issue. Original battery is on 50%. I charge it out of phone (desktop charger) and when returned to phone it's still 50%. I put in secondary battery, again says 50%. I let this one discharge to 40%, turn off phone, put in original one, again showing 40% as with other battery. I charge it in phone to 80%, put in secondary, stays on 80%.

At the same time I've been monitoring level of mV with some tool/app, and these go up / down logically as being charged / discharged.

So obviously battery % level is saved in system when physically changing batteries, which makes using 2 batteries almost impossible.

Any workaround for this? Anyone else using phone like this?
[Device Reviews and Information] Mbariah:
Just got mine yesterday and loving it...the build version is 20140609-211642..Jellybean..
[Device Reviews and Information] Mbariah:
Okay a couple of issues...

1. After deleting the "viruses" in the rom, a wierd menu appeared under Settings/Display and wont go away after rebooting

2. Does clear motion really help?am watching some Wiz Khalifa music videos and clear motion makes them go out of sync..i think videos were meant to be played at 24-27fps..not 60fps

3. Has anyone beem successful in correctly appying a screen protector on the G4s? Tips?

4. Its really hard to press the soft buttons especially at night..

5. Does the baidu ime keyboard come in english?

6. CWM..where do i start??

Anyone finding themselves switching clear motion off every now amd then?
[Device Reviews and Information] Ouzo:
Glad you like it. If GPS, camera performance and a few little bugs were fixed I would honestly recommend this phone to anyone. As it is, Jiayu aren't quite there yet for average users. They really need to sort out their updates too, both the process of releasing them and squashing bugs rather than introducing new ones. Anyway, it's still an absolute bargain.

Recently I discovered Jedi Knight II will work with the help of an emulator - awesome!
[Device Reviews and Information] Ouzo:
Just another one of the bugs. What annoys me more is that if you have headphones plugged in you still get notifications on the phone's speaker. Think this is an android 'feature' rather than a bug though as my old Note 2 did the same thing.
[Device Reviews and Information] Ouzo:
I still don't know of a way to fix it unless you install a deodexed ROM and the install xposed followed by the Gravity Box mod. See my link in OP for another method.
[Device Reviews and Information] Ouzo:
You need to use splashtools from your PC.
[Device Reviews and Information] Ouzo:
What ROM are you using.

I have two batteries and the external battery charger and the only problem I have is that the external charger will only charge a battery to 90%. No other issues for me. I'm on stock April ROM.
[Device Reviews and Information] Ouzo:
Looks like there's an epic camera bug that switches front and rear camera resolutions. Good to see Jiayu test their ROMs before releasing them. I love this phone but at the moment I wouldn't by another Jiayu unless the raise their game.
[Device Reviews and Information] Ouzo:
According to the thread on NeedROM for the latest KitKat ROM adding the line about min_match=7 to the build.prop does now work.

What's that caller ID issue you're talking about? I'm planning to order it tonight but i'd like to now all the bad things it has..

There's an explanation and a link to a thread with a very detailed explanation elsewhere, not to mention it has been discussed throughout the thread.
[Device Reviews and Information] mite_jan:
Fixible with replacing the lib file from v2

Also there is a rom with proper root and working camera on chinesse site 594n or something
[Device Reviews and Information] Ouzo:
Yeah, I read that, but I'm kind of gobsmacked that jiayu would make the mistake in the first place, especially as this is their third attempt at a KitKat ROM :) Kinda weak of them.

If they're not careful they'll become the Alfa of the smartphone world. Always something glorious about their designs but nothing but problems problems problems ;)
[Device Reviews and Information] GoJo ^^:
Seems that there's much choice in terms of rom compared to the 1s (which just go its stock miui apparently still).

I got used to miui, so i plan to use the miui rom (some people ported it), apparently it works great, anyone using it here?

ADD: I read OP about caller ID issue. Confirm buid.prop tweak works in any rom? GPS was fixed or still crap? And camera?
[Device Reviews and Information] Ouzo:
I've only tried the first two stock Jelly Bean ROMs, but GPS is iffy on all from what I've understood. Lock times can be very very quick or take five minutes. Accuracy when on the move is the biggest issue for most people.

Caller ID build prop tweak didn't work for me on Jelly Bean. Use a deodexed ROM with xposed installed and Gravity Box mod is one way to fix it.

The camera is weak for me. Images look OK on the phone but they lack detail and colours are off. Compared to a Note 2, Note 1 and an HTC Sensation they are worse. They're not awful though.

I would love a fully working MIUI ROM but each one I've read about has bugs.
[Device Reviews and Information] GoJo ^^:
Accuracy is the real issue indeed, long lock time can be tolerated for the price.. Regarding the camera : i found the 1S camera to be not so great and its flash SO WEAK (compared to my i9100); how's the flash on it (if you can compare to others)? Last things : Can you dual boot and would you mind trying the miui rom?
[Device Reviews and Information] mite_jan:
Yeah i am experiencing some wrong accuracy sometimes too like it gives me 10m of the street and the direction i am going is not 100 percent correct too

I was having problems too but after trying to fix with mobileuncle it is good for now locks like 30 secs without internet
[Device Reviews and Information] Ouzo:
Same here, but every time I think I have the lock issue fixed and back to normal after a few uses it suddenly takes a long time again. Lol, it's like a badly behaved puppy.
[Device Reviews and Information] Ouzo:
The flash seems fine to me. There's only one LED though so don't expect too much. Your Samsung has a better camera though for sure.

Sorry, I haven't looked into dual booting at all at the moment. I just need a phone to be stable and to allow minor tweaking via root.

Sorry, based on the comments on NeedROM I haven't seen an MIUI ROM that's worth taking the time to test yet, or where I feel I know enough about the developer to be happy enough to put all my data in their hands.
[Device Reviews and Information] pozzeco:
i9100 led are better too, it's more brighter than G4S led.
[Device Reviews and Information] Ouzo:
The changes save on the April stock ROM. I can show contracts from either SIM independently, or just in phone storage. I didn't try rebooting, but the changes certainly save after exiting the app and going back in.
[Device Reviews and Information] pozzeco:
Caller ID

Ok. I changed phone numbers: added international code to all contacts in phone storage (but not in sim cards). So question is: if i will choose show contacts only from phone storage, caller id will be shown?

But.. Then i select:

Contacts to display > Phone contact

it shows only Phone contacts, but this selection isn't saved.

I press Home or Back button, then press contacts icon, and it shows All contacts (from sim and phone storage).

How to save, that contacts would be displayed only from phone storage?
[Device Reviews and Information] Doman:
How do you display such info?

EDIT:

Found it :)

Dial *#*#3646633#*#*
[Device Reviews and Information] Ouzo:
If you run a custom launcher you can create a shortcut on your home screen to make it even easier. For example, in Nova launcher you tap and hold the home screen, select shortcut, then activities, then scroll down to engineer mode, expand that menu and select engineer mode. Hey presto, no entering numbers in the dialer or using Mobile Uncle/Jiayu ES apps.
[Device Reviews and Information] LuxZg:
Regarding this, those that used WiFi Display said that turning of screen causes problems with it. Did anyone try to play with settings in this engeneering mode -> Connectivity -> WiFi Display -> Power Saving for Playing Video -> Screen off/dim/no power saving + delay. Just seems apropriate to the issue... but maybe does nothing.

English changelog would be nice? :) Or someone understanding Chinese, I doubt at the powers of Google Translate for stuff like this :P

Seems that problem wanished, though I did play with some of those "calibration" apps that do nothing, but maybe they did change something after all. When I switched out almost empty one (6%) for almost full one (95-96%) it worked OK. Maybe when difference is not that large it thinks it's same battery or something, I don't know.

I use the "Polish official" ROM Doman posted here several days ago ( http://xdaforums.com/showpost.php?p=54978670&postcount=709 )

Aeonia, why not skip some of these problems and use the same ROM Doman posted (linked above).

1. Viruses are removed (actually never checked, but Doman said so :D )

5. Has AOSP keyboard, with standard languages

As for 3. - didn't try this one, but same as any I guess. Credit card or similar piece of plastic, piece of soft cloth, something to clean screen before application. Than do this: http://www.techarmor.com/media/wysiwyg/Installation/Instructions-For-Amazon.jpg

Though I prefer doing 5 & 6 at the same time (make sure to wrap the card in something soft so you don't scratch the protector on the first day).

Other way around is - just forget about protectors.. after I while you'll get bored with applying them anyway. I did.
[Device Reviews and Information] Ouzo:
Yep, tried tweaking the settings in Engineer Mode. It didn't make any difference for me, in the ways thatiI use wireless display. One of my problems actually went away after I updated the EZCast companion app for my wireless dongle so I guess the problem wasn't the Jiayu.

Actually, I'm not sure I've found a setting that truly save in Engineer Mode yet, especially after a reboot. I meant to try again mounting my system RW before tweaking to see if that is the issue but I haven't got around to it yet.

On a final wireless display note, I've just been trying out some new TVs in a shop and most new TVs with built in WiFi that support Miracast work very well indeed, offering full screen mirroring. Video remains a problem though with micro stutters, especially in scenes where the camera pans around.

Does your external battery charger get the battery above 90% charge?
[Device Reviews and Information] LuxZg:
Nope, I bought some universal charger from eBay, and it does charge it but not completely. Or I just wasn't patient enough.

I've just replaced my currently running battery (58%) with one I've charged last night for about 7 hours on the external charger.

Current battery, 58%, in BateryLog it says Battery voltage: 3870 mV.

Battery that was 6% than charged for ~7 hours now says also 58% at, 3924mV

Now, since I also have screenshot from 60% at 3939mV I'll guess it's filled to about same point, but is it 58% or 60% it doesn't really matter, it's a really slow charge, I'll have to find better one. Which one are you using, original one? How long does it take to those ~90% that you say is max for it.
[Device Reviews and Information] GoJo ^^:
I didn't know that website. Is that the page you looked at http://www.needrom.com/download/jiayu-g4-miui-official/ ?

I really can't see what's wrong.. The thread's here, quite big :http://en.miui.com/thread-10317-1-1.html

PS: Still looking for feedback from a person that had/have Xiaomi 1S and now use the Jiayu G4S..

[Device Reviews and Information] ykassana:
After a few months of trying this phone. (longest I've ever had a phone) Coming from a Lg G2 and S4 and Z1 - I think this is the best phone I've had. Everyone is different. But for me, these 3 things are utmost importance.

1. Battery Life

2. A half decent camera

3. Size and ease of use in the hand.

In the beginning it was tough. The stock JB was awful. I tried MIUI, but wasn't any good. Also problems with GPS, contacts and SMS. I was losing hope. Then I went onto Kitkat by TeamForce on needrom. So far so good. Great battery life and camera.

My camera is fast, my phone is fast and battery life is superb. Infact it's so good, that I've had to buy this phone for 3 of my friends. They all love it. Honestly, for £120 - this is a great phone. I will be using this phone as my day to day phone.
