If you download the "Band sync app" to your puter and turn on Bluetooth, pair the band to your puter it will work much better than the phone and it will sync everytime you put it on the puter USB charger. I have had my new Band about 2 weeks now and it is great but the corrosion to the back charging terminals ( they need to be polished up every day and some times 2 time a day for the charger to pick it up) leaves me believing it will not be a long time laster and will go in the charging drawer and only worn occasionally for reference to my time line health inquisitiveness.
