first, sorry for bad english.
a day, a soft (i forgot the name) ask me to set a 4 digit code to use all data internet connection.
but now whenever a software accesses to the internet I have to enter this code. sometimes 5 times
so, this code is on android settings ? i don't found it. or this code is on this lost soft ?
i have unstall lot of soft, so it's in the soft, it's a invisible soft
