I am running SD on an Android 4.3 tablet and on PC with Windows 7.
I try to create an aircraft profile. Part of that is to enter several fuel burn data. That works fine on the Windows PC.

But on my Android tablet I get an error message when trying to enter a decimal point, as the field is high lighted red when hitting enter. I have tried different on-screen keyboards. Doesn't work.

Here is what happens:
Tapping the fuel burn fields for Fuel, Climb, Descent, Power Settings ("Taxi/Takeoff", "Landing", etc) changes the selected field into editing mode and a keypad pops up. If I try to enter a decimal point and hit Next, then the field gets high lighted red and the entered value is ignored.

I haven't seen any thread on this issue on the forum, so is it only me having this problem? This is very frustrating, so I hope SD can fix this quickly.

Ok, then your problem is different from mine since I can *not* enter a decimal comma when a comma is required, but I *can* enter a decimal point.

If you don't see the "," symbol on your keypad, then that is related to the keyboard selected. I noticed the same when using the original Samsung keyboard (the popup keypad only shows numbers and "." for entering values in these fields). When I changed to SwiftKey keyboard, I could see the complete keyboard with all symbols, including "," "." etc.

Even if there is a "," symbol on the keyboard, nothing happens when I press it.

You are right. I see exactly the same. I thought you coudn't try "," as you didn't see it on the keyboard.
So entering a number with "." in any language mode causes the field to get highlighted red indicating invalid entry. Tapping "," is ignored such that 9,5 becomes 95.

I had expected SD Team to comment on this.
