Geolocalisation fix (aka no-sleep bug)
May 14th
All Galaxy’s users are aware of the no-sleep bug, fixing the device in a bad sleep status, after using Android’s geolocalisation feature,such as google map.
jakax found the patch on offical Android git and build the first patch, (http://androidforums.com/samsung-i7500/61168-no-sleep-has-nothing-do-anything-2.html#post701322), many thanks to him.
However, the first patch was really difficult to apply, and we could loose some specific features from our galaxy, by replacing Samsung’s apk and odex by aosp one.
I rebuilded the patch from scratch, then extract (deodex) the class from the AOSP patched version, and merge it into the official Samsung’s odex.
And voila, an easy to use-and-install geolocalisation patch for Galaxo.
How-to :
adb remount
adb push services.odex /system/framework/
adb shell reboot
enjoy

Audio Hack for Samsung Galaxy (test phase before included in Galaxo)
May 13th
A user from AndroidForums, balu_radu, found a way to change audio gain settings.
BE CARREFULL ! DANGEROUS SETTINGS ! YOU CAN BREAK YOU PHONE !
- Download http://www.drakaz.com/FILES/TMP/servicemodeapp.zip and http://www.drakaz.com/FILES/TMP/AudioFilter.txt
Extract servicemodeapp.zip in /data/app_s :
adb remount
adb push serviceModeApp.odex /system/framework/
adb push serviceModeApp.apk /system/framework/
- Push original AudioFilter.txt (prevent conflit with modified AudioFilter.txt and servicemodeapp tests) :
adb remount
adb push AudioFilter.txt /etc/
Then, reboot, and let’s try some settings !
headset music volume hack :
dial *#*#197328640#*#*, [8] audio -> [2] headset -> [2] rx value -> [5] rx codec for midi -> [1] rx codec gain, enter 5FFF for 4db, 7FFF for 6db, FFFF for 12db, 2014 for default
headset in call volume hack :
dial *#*#197328640#*#*, [8] audio -> [2] headset -> [2]rx value -> [1] rx codec/volume, enter 5FFF for 4db, 7FFF for 6db, FFFF for 12db, 4000 for default
speaker music volume hack :
dial *#*#197328640#*#*, [8] audio -> [3] speaker -> [2] rx value -> [5] rx codec for midi -> [1] rx codec gain, enter 5FFF for 4db, 7FFF for 6db, FFFF for 12db, 47d0 for default
speaker in call volume hack :
dial *#*#197328640#*#*, [8] audio -> [3] speaker -> [2]rx value -> [1] rx codec/volume, enter 5FFF for 4db, 7FFF for 6db, FFFF for 12db, 5a67 for default
Restore default settings :
[8] audio -> [5] Rebuild all
I repeat, BE CARREFUL with servicemodapp.

TetherWifi removed, because of a kernel issue.

Why there is no TetherWifi in Galaxo 1.6.3 ?
May 2nd
Because of new Samsung’s modified drivers are included in 2.6.29 sources. It doesn’t support ad-hoc mode, and essid configuration… when trying to enabling this mode, the kernel crash, and then, the interface seems to be frozen… i see the network, but i’m unable to send/receive data from the interface.
I’ve tried a lot of thing, to offer you tetherwifi, spending a lot of hours, but i failed :
- Porting BroadCom opensource driver : failed, module doesn’t detect build-in galaxy wifi chipset.
- Porting old 2.6.27 drivers to 2.6.29 : failed, it’s crash the device..
- Porting Spica BroadCom 4325 drivers : failed..
We can’t use another devices or opensource driver, because Samsung use direct I/O with the motherboard, to enable, disable, changing mod of the chipset.
Yeah, like the rest, Samsung have also modified the broadcom drivers.
Sorry guys, there will be no tethering in Galaxo 1.6.3.
Battery or performances ? Poll done !
May 2nd
Battery or performances poll is done.
Result :
- Battery : 51%
- Performances : 49%
- Total voters : 359
It’s difficult to choice between one or other, regarding the result !
So, i choose to set a mix settings, a little more aggressive than on galaxo 1.6.2, for battery, but not so agressive, keeping performances. I hope it will suit you
If not, you can instal Autokiller from the market.
