Battery icon not updating android
Then Press and Hold the Power button until the White Light is lit and the laptop/tablet turns on.Once on, you will see that the Battery is calibrated and will show accurate results and indeed cure most of the battery problems (not charging, unable to charge, battery stuck).
Usually do this before going to bed, wake up and when you get time, then turn it back on by holding the power button for a few seconds until the white light turns on, doing so I realized the battery showed accurate results and not prolonged the previous issues stated otherwise above.
To access any other day, "logo_calendar_01_regular" would be changed for the current day.
For example, day 7 would be "logo_calendar_07_regular".
For instance it might be the planetary app that reflects planets' positions on the icon. I just get the activities' icons by the standard way provided by Android API.
Or memory cleaner that shows percentage of used memory... And I found that my launcher do show the current time in the Clock app icon and the current date in the Calendar icon. The operating system should have done something with the two apps and changed their icons dynamically without the launcher beings aware of it.
These two apps are developed by the device manufacturer.
