4.06 beta is definitely buggy on my FR 245m. disconnects from my phone to watch got worse every day.. nothing was syncing because the watch would disconnect. it got so bad, that i would sync it, and my Connect app would never say connected. I even restarted my watch at least 2 times. I do think the battery life is better on the beta. And i did not change many settings on the watch. i have a few watch faces loaded, and 1 race data set. i loaded the zwift (big app, 650+mb) and ran with it a couple of times on the treadmill. even on my 6"+ phone, its still a little screen to actually enjoy and read the small/tiny fonts. . i would run with a big tablet, but the tablet really doesnt fit in my pocket. its definitely a neat concept. does anyone know if there is an simple app where i can watch typical stats on my phone? (time, distance, heart rate, avg pace..) on my phone.. with bigger fonts that are easy to read while on the treadmill?
i went back to 4.00 after about 4 days. i'll stay with the 4.00 for now. its stable and i get my text notifications w/o issue.
