My Brother have Xperia C3 Dual
1- There is no option in sound settings for turn of the boot up sound, Like Xperia Z2 and Z3 have Please Give us an option to turn of booted sound.
2- In other companies’ Dual sim phone when we open phone app then we have Operation names on both Call buttons, but in C3 we have Sim1 & Sim2 instead of Operator names. I know this is a minor thing for Sony to do it, so please give these two thing in next update
