My name is ashwin khadikar i am using xperia sp C5302. I updated my xperia sp to firmware 12.1.A.1.205 latest one. Although it is an impressive and improved firmware but i feel that battery backup should be improved than this and i want that Led light should be on during Calls ,Applications should be able to move in SD Card as wel as xperia sp should get 64 Gb Card support. Lastly the themes which sony is giving it should have different colors ,right now there is only one basic colour ie blue for each and every theme.As xperia sp is famous Led illumination so there is no versatility due to this common color of Led in themes Sony should also improve sound quality during call,music play while playing songs in loudspeaker it should be loud.!! Lastly sony should give Hd voice quality sound in calls
