Cách Tăng Tốc Bắt GPS Cho Android
Thể loại: Thủ Thuật

Trên một số dòng sản phẩm smartphone/tablet, thì thời gian bắt GPS rất lâu, như một số dòng Qualcomm hay Mediatek, hoặc trên một số bản ROM Android, thì có các thủ thuật sau cải thiện đáng kể vấn đề GPS:

Lưu ý: Nếu smartphone/tablet Android bạn đang bắt GPS tốt thì không làm theo các cách này! Và trên một số thiết bị thì lần đầu bắt GPS và thu thập dữ liệu sẽ mất hàng tiếng đồng hồ, nhưng sau khi đã cache rồi thì lần sau sẽ bắt rất nhanh 😀

Thực ra, bây giờ smartphone/tablet đều hỗ trợ định vị vị trí bằng wifi/3G với tốc độ rất nhanh và chính xác, nên cũng không quá quan trọng việc tối ưu GPS nếu không cần thiết, nhưng có thì vẫn hơn 😀

OK, các cách được dùng nhiều để cải thiện vấn đề GPS:

1) Hiệu chỉnh file gps.conf

Ok, here comes another trick. Open your gps.conf file (inside system\etc):
It will looks like:
NTP_SERVER=europe.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
SUPL_HOST=supl.google.com
SUPL_PORT=7276

Now change it to:
NTP_SERVER=0.pl.pool.ntp.org
NTP_SERVER=1.pl.pool.ntp.org
NTP_SERVER=2.pl.pool.ntp.org
NTP_SERVER=3.pl.pool.ntp.org
NTP_SERVER=0.europe.pool.ntp.org
NTP_SERVER=1.europe.pool.ntp.org
NTP_SERVER=2.europe.pool.ntp.org
NTP_SERVER=3.europe.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
SUPL_HOST=supl.google.com
SUPL_PORT=7276

Remembering to change “pl” in first 3 servers to the letters of your country. Here is the list:

Cách 2:

People with GPS issues, try two things:
A1) Go to Settings -> Location and check “Integrate Google Navigation”
A2) Enable “Use GPS satellites”
A3) Reboot and try with Google Maps

—————————————–

B1) Download FasterFix and chang the ntp to: it.pool.ntp.org ( “it” for me in italy, other for you, see list below )
B2) Download GPS Status from market.
B3) Clean Chache/data on Google maps.
B4) Enable GPS
B5) Reboot into recovery and wipe dalvik cache and reboot.
B6) Open “GPS Status” and wait for a satellite Fix
B7) Open maps and it works xD

Optional
B8) uninstall fasterfix and gps status
B9) Go to Settings -> Location and check “Integrate Google Navigation”

Let me know [​IMG]

-I tried many times and the issue seems to be caused by the “Integrate Google Navigation” not enabled..-

Cách 3:

Ok so based on what Simkin84 wrote I will add following method to the F.A.Q. :

Edit your gps.conf file inside system\etc\ and add following 2 lines at the end of the text:

C2K_HOST=default
C2K_PORT=0

Then save gps.conf file and restart your device.
