Samsung S3 Frontier LTE SM-R765A Original Motherboard: Compatible with Samsung Galaxy Gear S3 Frontier LTE
Looking for a solid motherboard to bring your Samsung Galaxy Gear S3 Frontier LTE SM-R765A back to life? This one's your guy. We've given each one the once-over (and then some) to make sure it's in tip-top shape before it heads your way. Rest easy knowing it'll slide into your device like it was made for it—because, well, it was.
Heads up: Unless you're the kind of person who can solder with their eyes closed, you might want to leave the installation to the pros. (We love a good DIY spirit, but we can't be on the hook for any 'oops' moments during your tech surgery.)
