AGPS Patch Improves The GPS Performance Of Galaxy S II, Sensation and Other Handsets
By on January 24th, 2012

The Samsung Galaxy S was without a doubt one of the most popular phones of 2010. The phone sold in excess of 10 million units, and has phenomenal developer support. However, the phone has had its fair share of issues including the RFS file system, which lead to the lagging issue on the phone, and a totally unusable GPS.

Thankfully, Samsung fixed this issue on the Galaxy S successor – the Galaxy S II. As a Galaxy S II owner, I have perfectly no issues with the phone’s GPS performance. However, newer Android phones like the Droid RAZR, Galaxy Note come with a Barometer and GLONASS support, which improves the GPS location accuracy and the lock-up time as well. Many Galaxy Note users report a cold-boot GPS lock time of only 4-5 seconds on their handsets.

There are quite a few tricks out there which can enhance your phone’s GPS performance and accuracy, but none of them can replace bring down the GPS lock time drastically as a Barometer and/or GLONASS does.

Now, one developer – crypted – over at XDA forums has released an AGPS patch that improves the GPS functionality of the Samsung Galaxy S2. The patch works for quite a few other Android phones using Qualcomm chipsets, and is ROM independent as well. Keep in mind that you do need to have root access on your handset to use this patch.

Below is the list of devices officially supported by the developer’s AGPS Patch -:

HTC Inspire 4G
HTC Desire HD
HTC Sensation
HTC Incredible S
Acer Iconia
LG Optimus One
Sony Ericcson XPERIA X8
HTC Salsa
HTC Flyer
HTC Evo 3D
Samsung Galaxy S II Skyrocket (SGH-I727)
Samsung Galaxy S II (I9100)
HTC Desire S
Motorola Triumph
HTC Wildfire
HTC Wildfire S
HTC Droid Incredible 2
HTC Thunderbolt

There are three different variants of the AGPS patch available. v1 only changes the GPS NTP server, while v2 and v3 contain some modified GPS files and uses an AGPS server of the developer himself, for providing users with ultra-fast GPS lock times and improved accuracy.

There are 3 different methods to install the AGPS patch, but flashing the AGPS zip file via CWM (ClockWorkMod Recovery) is the easiest of them all. I tried the AGPS patch on my Galaxy S II, and definitely noticed a noticable improvement in the GPS performance of the handset.
