on my Wife's Samsung Note 3 phone the keyboard does not give her a . to enter amounts. it only shows numbers. so she has to enter price and mileage on notepad then copy and paste to entry field to get it entered.
also personally preferred the old interface to the new one. i just like the simplicity of it. wish we had a choice to use minimal or detailed when entering info. please consider this.
I had that problem once too on my Note2 running a TouchWiz keyboard. I think it was because I was using Google Chrome Mobile web browser; using the stock browser fixed it (stock browser is faster anyway), although the decimal point was still buried underneath the symbols menu (annoying).
