App displays blinking of another screen after bluetooth connection

[Ggaayi Abraham]

Immediately I finished building the app, I uploaded it on my phone for testing.

but after the connection between the bluetooth interface and car, shifting from one screen to another, it started blinking and eventually stopped working.

What could the problem be?

I am guessing that there is a test for bluetooth connected on screen 3, if that fails calls Screen2

The bluetooth connection is lost when switching screens

Don't know how the clock timer is called but if running all the time you will see the behaviour you describe

The app eventually stops probably because you are not switching screens correctly and have a memory blowout

Use different screens wisely

• Before starting to create another screen, first you should think about is it really necessary? 
  
• See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... 
  
• See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd. and my Tabbed Screens Demo
  

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
