Need some advice before modifying my device

Hi all, This is my first post at XDA so please kindly correct me if there are something wrong.
I have purchased SSGS around 3 week ago and found that there are some minor problem with my device. The phone still usable but some of these problem are quite annoy. Below are some problem with my device.
1.) There are some lag when opening/closing apps
2.) If I turn on "Use wireless network" in Location setting sometime my Wifi automatic turn itself on and fail to automatically turn off (The wifi status at notification bar turn green and said "turning off" forever and the only solution i get is to restart)
3.) After restart sometime my EDGE connection will not working properly (the "E" symbol is appear at notification bar but the data is not flow, can not connect to the internet) the solution is to restart again or connect to Wifi network that can access to internet and then turn the wifi off.
4.) GPS seem to be very slow.
5.) When turning off Wifi sometime EDGE connection is not auto reconnect (need to turn on and off flight mode to reconnect the EDGE)
After reading this forum for some time. I decide to try to solve those problem permanently however I would like to have some advice from all of you who have experience first.
My device is running on Asian stock firmware I9000DXJF4 and already rooted. Below are my plan for modifying and also some question.
1.) Backing up all of my apps and data. Which backup apps should I use? Titanium backup?
2.) Flash to European firmware via ODIN. Which firmware is the most stable JG5, JM2 or I should advance to Froyo JP2? Are there any problem flashing from Asian to European firmware?
3.) Rooted and installed busybox
4.) Restore my apps and data. After restore, my apps still be able to updated via market or not? Especially some paid apps
5.) Apply Mimocon's Lag fix.
Does above procedure seem to be ok? Am I forgot something?
Thank in advance for your advice

about GPS position, pls do following to optimize
*#1472365#* -goto GPS setting mode
Application Settings :
Operation Mode : Standalone
Accuracy : 30
Use Skyhook: ON
SUPL/CP Settings JM2 no need change this)
Server: Supl.google.com
Server Port: 7276
/System/etc/gps.conf
NTP_SERVER=north-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
change first line: NTP_SERVER=3.tw.pool.ntp.org -----NTP_SERVER=tw.pool.ntp.org
(or use you country code)
reboot
make sure you internet connective when you first open GPS positioning.

Thank for the information about the GPS fix.
Still need some advice before flashing new firmware

2.) If I turn on "Use wireless network" in Location setting sometime my Wifi automatic turn itself on and fail to automatically turn off (The wifi status at notification bar turn green and said "turning off" forever and the only solution i get is to restart)

I have this problem too. I'm on stock XXJF3(?) firmware. I'm thinking about switching to XXJP3 froyo firmware.

I have read some where around here that this problem have been fix in new firmware but my problem now is that I don't know which one should be used.

[Q] GPS Standalone doubt (Clarification required too)

I know SGS has a lot of issue with GPS. Here's mine. I've cold start and standalone set-up in lbs test mode. Now the problem is it'll lock on to satellites in a matter of 20sec with 15m accuracy only when connected to wi-fi couldn't check for gprs since sgs doesn't save my apn =(. But with wi-fi switched off it doesn't speak to any satellites forget about getting a lock on them. Doubt here is, isn't standalone mode supposed to be GPS working without any data connection of any sort or am I missing something here? Kindly clarify. Also what does MS based and MS assisted mean in the test mode. Checked for GPS with Network Provider selected in test mode. I get accuracy of 3.8km here at my home....
Thanks & Regards

I just tested indoors (rainy here) and the SGS did get a lock. I've switched off cellular data and wifi, cleared the AGPS data with "GPS Status", and it took a long time (few minutes) to get a lock.
But that was indoors, where it always takes a bit longer to get a lock.

I tried it outside last evening and it would only see the sat's no lock =|

[Q] How to disconnect WIFI automatically when phone suspends?

The ROM I use (wm6.5, 3.09 driver, M2.5) does not disconnect WiFi when it suspends. It drains the battery very quickly if I forget to turn off wifi. I wanna write a script to make this function (turn off wifi or not when suspending) a configurable choice, and then map to a hardware button.
I searched on web. They said that changing the key "HTCkeepwifionwhenunattended" to 0 can disconnect wifi automatically. Some of them said that this only works before next soft reset. But for me, whenever before or all after reset, it doesn't work at all. No matter the value of this key is 0 or 1, wifi connection is kept alive after suspending.
Any one tell me why? This is common or a special problem to my rom? any other methods to turn off wifi after suspend or some idle time?
Thank you guys a lot!!

anybody knows? help pls! big thanks

you should just use the Touch X DataDisconnect

TWEAK Reply
For the longest time, I had the opposite problem: I was forever annoyed that the WLAN would automatically disconnect every time I turned the device off. Then I found two very handy utilities that can fix (or unfix, in your case) that and many many other things. I use Advanced Config and DiamondTweak. Incredibly useful pieces of software.

Thanks for the reply. But this is not what i need. I want wifi disconnect automatically when screen goes black. I often forget to turn the wifi off and after a few hours finding battery drained.

I installed it. Is "turn off wifi if no activity" the right item? I change the value to Yes, and "wifi auto off timeout" is set to 30 seconds. But it still doesn't work

I find the place. It's in ACT's menu->more settings, uncheck "keep wifi on when standby". However, it still doesn't work...
Probably this setting just modifies "HTCkeepwifionwhenunattended" in the registry， which seems not make any difference in my system.
I'm going crazy...

I finally find the reason. That's because this ROM doesn't use the default wifi switch interface. It wrote its own .exe program to turn on and off the wifi, maybe by which it bypasses the registry tweaks.
By using the system wifi switches, the modification of registry works.

why you don't try Bandswitch...??
Bandswitch has a function Take control of your connections: Switch between 2G-3G Enable and disable connections. Disabling connections makes imposible to use them so you know they wont generate traffic data. Stablish and close connections. Set a time frame where connections wont be allowed (ie, when you are sleeping) saving money and battery.. Turn off/on Bluetooth and Wifi with or without time limite. When the limit expires then It is set to off state
but if you want to know the registry tweak to disable or enable the wifi connection , like here HKLM\COMM\TNETWLN1\Parms\dot11SupportedRateMask = 1 (DWORD decimal) is enabled

In advanced config app,under the Network sub category you will find "Wi-fi auto off timeout".Set the time as per your requirements.

[Q] Is anyone able to locate yourself with GPS alone?

With data from network I can identify the location instantly. However, if I uncheck "Use wireless network", I have never located myself on Googles Maps. Is it a defect on the GPS?
Thanks in advance!

Google maps doesn't includes world map installed, it only store some caches.. you still need network to download map data & network based location, GPS is used for more accurate result & yes it's true p970 gps is not so good.

Thanks for your help! In fact, I already have cache of Google Maps, then turn off the wireless connection, to figure out the performance of the GPS alone. It sucks!
BTW, I used HTC Touch before and its GPS could identify the location very quickly.

have you test with the GPS fix (in hidden menu) ?

Actually you are wrong, GPS in very good in OB.
I used it for a trip of 700 KM and it has difficulty only the first time when it aquires a position (this is normal if you don't use AGPS) like 3-4 minutes...
On the road I turned off GPS by simply locking the screen (IGO8), and on relaunch the GPS position will not take more than 30 seconds. I don't have any data on my contract so it was purely GPS!
The first time it's normal to take a very long time because a large number of sattelites have to be aquired to for pin-point accuracy. Afterword I think it works with 2-3 visible sattelites!
My previous phone was a HTC Diamond, and it was exactly the same if I dind't used the GPS app every day that downloaded sattelites in advance.

It works but it's slow (as it should be). For me it's around 1 minute in hidden menu. Best place for testing outside hidden menu is Compass app (If you don't have data connection for maps)
For hidden menu:
1. Go into the LG hidden menu (3845#*970#)
2. Go into GPS Test
Test it (you need activated GPS of course)
if it's really slow, try this (I think it's if you use network to pinpoint but everyone is suggesting it, so I will too)
1. Go into System Settings
2. SULP Setting -> SLP Server Setting
create new:
Nokia (slp address: supl.nokia.com, port: 7275, no cert and no TLS setting)
If it still doesn't work, try other variants (LGE SUPL, Spirent, etc).

Thanks everyone!
It works now! The. GPS is quite sensitive!

In the gps test in the hidden menu, there's not such option as gps fix.
Me too, I'm interested in using my gps without the assistance of the network cells. I've already tried the three supl servers and it doesn't seems to work for me. So, if someone knows how to use it without network assistance I'll be really grateful.
Thanks in advance.

It should work out of the box.. afaik, you don't need to mess with the SLP servers unless you are using some sort of assisted GPS mode (with wifi or 3g connection). I'm using it straight out of the box (after installing the fresh firmware) and it works normal in the car (1-2 minutes first fix, a couple of seconds for any other subsequent fix). Getting a first fix while on foot does take a bit longer, but that's true with all the other non-android devices I've had. the OB has normal (no more, no less) sensitivity when it comes to GPS.

i think there it`s a problem in OB mine has problems with gps too , and already o try`d all kind of apps and even use the gps standalone from the fresh new update soft and nothing , fix the gps for the first time and after then i can`t travel with standalone gps

Localization in 4.4.2

Anyone could pls explain how localization now works on 4.4.2?
In 4.3 I could have localization thru 3g on and gps off, then I'd turn gos on with a switch when using maps on nav app, and ogff again when finished.
Now all I have is a switch that enables/disables localization and an option with 3 way of working: 1. gps + 3g + wifi, 2. Gps + wifi or 3. gps only.
I am lost... If I choose option 1 than is my gps always on sucking battery? If I choose 2 how can I easily enable gps when in nav app? And if I choose 3 how can I still have google localize me thru wifi when localization is off?
This is so stupid, they should have kept 3g and gps localization separate...

Hi! Please see this how to for guidance with GPS settings in android 4.4.
https://support.google.com/nexus/answer/3467281?hl=en
Apparently the options are practically the same as in 4.3 and just a little bit changed on 4.4.
High accuracy = Should enable both AGPS & onboard GPS Sensor to fetch your location.
Battery saving = Should only use AGPS.
Device only = Should only use the onboard GPS Sensor.
where
AGPS = uses an internet connection(3g and/or WiFi) to get your location.
GPS = uses the built in GPS chip inside your device and connects to GPS satellites to fetch your location.
So in your question.
High accuracy mode in android 4.3 is just like checking both "GPS Satellites" & "Google's Location Service" option at the same time.
Battery saving mode in android 4.3 is just like checking only "Google's Location Service" option.
Device only mode in android 4.3 is just like checking only "GPS Satellites" option.
You could just switch to high accuracy mode when you want to use maps with GPS on and switch back to battery saving mode when you're done using it.

Anyhow, before I could leave 3g localization on all the time and enable/disable gps with a switch, now I have to go into the option to do this

There really isn't a need to keep GPS off while not using a location app. Your phone will only turn on the GPS receiver when an app asks for your location. It doesn't just constantly stay connected to satellites while the phone is in your pocket. I always have GPS enabled and there is no effect on battery life.

Actually aGPS still uses satellites. It just uses your data connection to do one or both of the following:
1. Download satellite reference data to know the position of satellites more quickly for a faster fix
2. Uploads your GPS signals your phone gets from the satellites to an external server which can calculate your location more accurately using things like atmospheric conditions and weather
aGPS is why a phone can get a GPS fix in seconds while a dedicated GPS device might take much longer bc it has to download the reference data from the satellites itself.
What you are referring to is a network estimated location, which isn't the same as aGPS. In fact your phone will always have aGPS enabled if you have GPS enabled.

Well if that's the case with AGPS care to explain how Nokia Maps were able to pinpoint my location years ago when I am using my good old n80? It has assisted GPS but no onboard GPS and as far as I can tell nokia map works on that phone.
@thegios
Not sure if there's any widgets for the new GPS settings of google. TBH though for every upgrade of android eversince jellybean I'm starting to get turned off from android. They're like taking out the features of android 1 by 1.

Got to say i hate the new GPS switch layout, was wondering what the hell they'd done when i first saw it.
Someone will create a switch for it somewhere along the lines, in the mean time just leave it on battery saver mode and switch to high accuracy when you need to drive or something similar which requires full use of GPS.
If the community (us and everyone else) makes enough noise about it they may bring it back.

well as @301stSpartan says, even if in high battery mode, it seems the gps is fired only if an app is requesting, so at this point i wouldn't mind and leave it always in high mode

Yea you could but the amount of apps that fire up the GPS is quite a lot, and if youre inside then it's going to try to communicate with satellites and it won't be able to, it'll hit battery, i've no doubt about that.
