Solution:
1. If it is a software problem, such as several data errors, such as abnormal data of personal information, it will cause errors in the synchronized data, which can be carefully checked in "personal information".Such as height, weight and other data.
2. if it is a hardware problem, such as water, it may be connected to the loss of data, and then the water can dry for several days, and then corrosion of the motherboard, there has been a problem.This is a hardware problem, because the band can not prevent water vapor, so when taking a hot bath as far as possible to take the hand ring, to avoid the interference of water vapor, in addition to the daily use, as far as possible to keep the bracelet dry, do not leave water stains.
3. It may also be that in the process of synchronization, the band of the mobile phone is broken, such as system Bluetooth crash, WiFi switch, incoming phone call, etc. When the app operation of the upgraded band is carried out, the synchronization error will be caused. For the occasional data loss, please try to unbind and rebind the band in "my band", which will restart the band.If frequent loss of data on the need for after-sales.
