Emu48 help

[Gil]

1) Just changed my phone for a Samsung A53.

2) Installed the EMU48 application on it.

3) Chose the cropped version hp50g in the "New..." Menu.

4) Loaded all the previous programs.

5) Everything works fine.

6) But when I close all the applications on the phone and want to open again emu48, the access is denied.

7) Then I have to procede again from step 3 to 5, which was not the case on my previous phone, a Samsung galaxy S6

Could somebody help me, when closing the application, that emu48 could be "normally" opened with the initially calculator choice HP50G, including the previously given programd, avoiding the step 7?

Regards,
