@c0n57an71n Ok thanks. should have been more precise: in fact what I'm most interested in is whether the cellular data works, i.e. whether the internet works with SIM (doesn't work at all for me with SIM on the Volla at the moment, ok with wifi) : so it's the conf managing best the SIM APN and cellular data that I want to test.
@domubpkm & @lduboeuf Thanks guys for explaining to me. I hid the keyboard like you suggested & it froze again, but when I selected the menu before typing, the menu choices actually loaded in the new window. You basically need to be out of "text entry mode" before you tap the dropdown menu. Thanks again😊
