using GPS sucks the battery.
even when i'm using standalone garmin, i always need to plug in the charger if not will be low battery after a while.

not really gps and 3g data is the one killing the battery

if use sygic is only 3g. my battery only shades around 15% every hour.

yesterday just applied my sgp curved crystal

1st sp application failed, have to throw it away, wasted
2nd one is smooth and nice

alignment of the holes not right. so i pull off the sp to apply it again. but who knows when i pull it off it messed up the entire sp
jz be careful and make sure the holes are properly aligned. other than that its same as any normal sp installation

use the hinge method. succeeded on the first try for me

For me, I didn't peel off the front protective film until everything is done.
After i squeegee all the bubbles out, i just peeled off the front protective film, and the cellophane tape came off along with it. No residue

Usually cheaper SP like pasar malam type is single sided. At least that's in my experience lol
