Important:
If the Apple mobile phone is not used for a long time (2 hours), in standby or
hibernation (in a state of blank screen), H Band may be cleaned by the Apple's
IOS system. When the connection of the APP and a watch is in the off state, the
APP function will not be able to use. Open the APP again, it will automatically
reconnect on watch.
After installing the APP on the android phone, you need to open the background
application startup permission in the Settings of the phone, which is different for
each phone. Take Huawei mobile phone as an example, the steps are as follows:
Setting - Application -Application Startup Management-H Band, find the
applicationchange the automatic management to manual management, and open
all permissions (allow self-startup, allow associated start, allow background
activities). This work is only for the application to keep the Bluetooth connection
with the watch without the Android system cleaning up when the phone is in
standby (the phone has no bright screen).
