Is u4fit being closed during a workout? Take a look here!


#Huawei  #Android 8+  #Samsung  #HTC

Are you running with U4FIT and lately it is being closed right after you start your workout?
The recent update to Android 8 and earlier versions is causing some apps like U4FIT, that need to stay alive even when the screen is off, to be killed by the system to limit battery consumption.
This doesn’t depend on U4FIT! The same issue is affecting all the applications that need to stay in execution when the screen is turned off or the device is locked.
If you are experiencing this issue, please take a look at the following guide.

Huawei devices
Verified for the following models: p8lite 2017, p10 lite, p20 lite
1) Access to phone setting and tap on "Battery"

2) Then click on “Launch”

3) Look for U4FIT on the list and tap on the button on the right to disable the “manage automatically” function as shown by the following screenshot:

4) Then you will see this screen
VERY IMPORTANT: enable all the three options as shown above then click “OK”.
In this way, you are allowing U4FIT to stay active even when the screen is off or the device is locked so that the workout won’t be terminated by the device.
