Hello guys im in desperate need of assistance as i have the xperia x dual and a xa2 ultra dual h4233. Ever since the nuuksioo update i have issues with using ussd codes. The issue is as follows, when i run a ussd code to check for balance it works, however when i use a ussd that requires several serial entries it ends up telling me the operation is already in progress and it wont respond until when another response appears indicating that the argument was not recognized. Please help as this makes it very difficult to execute carrier transactions
