First main thing which use of mobile phone is most important conversation but this is the worst that there is very dull sound reception and its android but as usual sony add its own useless features replace with android simple features like messaging replace with hangouts than music is walkman etc.so its very confusing for users so not easy to use for first time using sony phones and style design and look almost same as usual all sony xperia just size is change aa per price so other nothing attractive and no extra features gatures like other new brands and its battery backup is so weak as you have to plug in charger continue whole day even in idle condition its battery drain automatically actually not draining its jumping like 98% to 88 so very worst totally disapointed by every aspect of mobile total waste of money
