For the ROM devs of the XDA community, forum member bohdans has provided a little bit of help by sharing a useful little script for creating a ROM package for a certain Country/CSC.

The ROM Packager is a batch file that will unTar/Tar Odin compatible files to flash. Additionally, the script selects the relevant files for each type (Phone/PDA/CSC/Full) and will create .md5 files for flashing and can compress to 7zip.

The script will then automatically use the required files to make a CSC, Phone, PDA or Full type flash file and can auto split a single flash package into 3 separate ones.

For more information and to download the file, check out the forum thread.

If you want to keep the LEDs behind your Samsung Galaxy device buttons on whilst the screen is on, try out Keep The Lights On – an Android app developed by XDA forum member Guardian_Bob.

One of the main reasons for this app, is for those of you who have installed i9000 based ROMs on your device. Although the stock ROM turns on the LEDs when you touch the screen, the i9000 based ROMs do not or have a timeout of approx 3 seconds.

Be assured that surface LEDs draw very little power, so no need to worry about battery drain. Additionally, Keep The Lights On 1.3 works with other BLN apps such as Blinky.

Keep The Lights On is a widget based app hence won’t appear in your app list. The app is available free from the Market (although a Pro version is also available with more features).

GPS is one of those great innovations in the mobile smartphone market, as well as a nice piece of engineering. Some manufacturers really face the challenge to produce smartphones with great GPS hardware – a feature that has often been under exposed by many people; there aren’t much reviews covering the GPS quality. There is a pretty big difference in GPS quality between different manufacturers though: HTC does a great job at creating high-end hardware and software, but Samsung seems to be concentrating too much on other aspects of the device – the screen perhaps? Anyway, many people are saying that the GPS quality of the Galaxy devices is bad. And I guess they’re right. XDA member dangrayorg decided to write a very nice article which describes not only the basic technical side of GPS and why Samsung fails to deliver proper GPS functions, but he also created a guide with some advanced steps to improve the GPS functions on the Galaxy S.

I’ve tried very hard to write a definitive post on SGS GPS performance. Below I try to give a balanced view of GPS performance in the SGS and provide definitive explanations of the various functions offered by the Broadcom BCM4751 chipset and their effects on the quality of the GPS fix. There is a lot of noise and conjecture on this subject in the XDA-developers forum; some right, some wrong, some missing the point entirely. Below is some educated guess work and some hard facts about exactly what will and will not help with GPS performance on the Samsung Galaxy S i9000.

Ever wondered what your mobile phone radiation levels are like? Wonder no more, with this monitoring tool from XDA forum member tawkon.

The app monitors your exposure to mobile phone radiation so that you can ‘talk on’ as usual, whilst receiving smart prompts to avoid radiation just when necessary.

You get real-time alerts, stats and user-generated radiation zone maps as well as a tiny home screen icon that changes from green to yellow to red indicating low-moderate-high levels of radiation exposure at any given time.

Tawkon is in beta, and is available to download for free from the Market. Currently supported are Samsung Galaxy S devices (Vibrant, Captivate and GTI 9000).
