When we click the ‘back’ button, gaia send a back command to gecko and set a timer. If no message returned in 4000ms, we will return to the main settings menu； if gecko returns a message,the timer will be cleared and  return to the previous menu successfully. 
However, sometimes, gecko returns message to go back to the previous menu, before the timer was set up, so the timer can not be cleared properly, caused the exiting to the main menu.

Hi frsela：

In China Mobile's STK applications,one can search the contacts in the SIM according to the letter which is input by user. In this case, when we click the 'back' button, it will popup a window. The gecko will not return any message until we input a letter to search contacts or select to go back or close the application. Once we stay on the window over 4000ms, the settings app will reset to the main menu like the video below shows: https://mega.co.nz/#!8VEGBRhB!rp4OdhHgIHdYDJBYfmpY8t0_KLffVY6yd0-EolIYkSs

Is there any way to solve this problem? Thank you.

I think When we click the back button and popup the window let us to input, we also should stop the timer of going back to settings main menu. 

This issue showed in comment7 can also reproduced in flame and v2.0.

Hi,

There's a timer[1] which returns to the Main settings menu if after back button is pressed no more STK commands are received from the SIM card.

Anyway, if you receive the INPUT STK command (as the video shows) this timer should be cancelled [2]. stkCancelGoBack is called for any STK received command.

If you can provide (Better in a new bug) some traces (better adding new ones in these parts of the code) to assure the correct application flow and to get the exact STK commands received...
