Decimal input questions

Dear all,

I have a survey with numeric questions set to two decimal places. I have Samsung galaxy tablets (models A & E). The same survey has been uploaded on all the tablets but for some reason the keyboard for the numeric inputs (on 13 of the 52 tablets) won’t allow for a decimal (i.e. these have the standard square 0-9, with a back arrow and done buttons while the others have the 0-9,done,back arrow plus punctuation & settings). All tablets have the newest version of the survey solutions app.

I’ve checked, there’s no setting for the app on this. I’ve checked the keyboard settings on the device and cant seem to locate the fix on the problem. Please advise if anyone else has had this problem or if there is a fix. I’m a bit stumped.
