Slider not visible

[dora_paz]

Try to change Theme to Classic from Screen1's properties, also set Slider's width from automatic to 90 percent or fill parent and see if it works for you

Slider shows and a very thin line with no thumb slider

Is this with the Theme setting on Screen1 set to something other than Classic? If you’re using the emulator, you’re likely getting the Classic theme by default (since it’s an old Android version) and that would explain the visual difference you’re seeing between the emulator and your phone.
