I put on the watch for all day 8/21, 8/22. In the morning of 8/23, I received a text displaying battery is low and to charge it. The steps that get recorded on the watch are consistently higher then the flex by about 10%. I was able to get the watch to re pair to the windows phone after a lot of random troubleshooting.
After the first day of using the kreyos just paired via Bluetooth to my phone I noticed that it says I walked 3000 more steps than what my fitbit says. I borrowed my mom’s android phone. Reset the smart watch and paired it with my mom’s phone. It then did the firmware update from 1051 to 1071. Reset the watch again and now it will not connect with the windows phone at all anymore.
