Yes. 46mm Bluetooth. My G3 is an LTE with Verizon, but I hardly used it away from my phone. Some runners might benefit from the LTE, but the downside was waiting for Verizon to update Tizen well behind the Samsung updates.
True. The Tizen 4.0 will be available for G3 I’m sure. The greatest plus for me so far is the remarkable battery life. Only 24 hours of testing so far, but I’m seeing similar reports of battery life on other posts. The enhanced sensor on the Galaxy Watch seems to be giving me much better fitness tracking so far. I’m waiting to see if Samsung enables APIs to monitor blood oxygen with the new sensors as is rumored. I’m wearing a FitBit Versa on the other arm and tracking with Galaxy Watch (steps, heart rate, distance, floors) seems to be much better than my S3 so far.
I also tested the processor upgrade. About 40% faster at transferring music, photos and watch faces compared to the S3.
