Greetings from Syncfusion.
Query 1: it's impossible to enter decimal values.
Yes, there is an issue in the frame work that the decimal separator key (comma) is not shown in the keyboard on SAMSUNG devices. You can refer it in the below link.
We made an improvement to resolve the above issue is, allows the dot as comma separator for the culture which is based on Azerty keyboard. But the value will be updated with comma after the control is unfocused. This improvement has been moved in our Volume 1 2019 SP1 release v 220.127.116.11 (feedback link).
Query 2: I was able to enter the value 5,5 using my Xiaomi MiA2, but it saves me 55 instead of 5.5.
