This phone launched in 2014 maybe September, so its a budget phone by sony and yeah it is besides that you can get a far better phone from MI at the same price but sony is the brand not everything is bad about this phone
lets talk about details
screen size - 4.5 inch better than rest of budget phones by sony
Resolution - 480*854 NOT HD but still woth it
Storage - 4 GB But only 1.7 GB is usable I should mention it
Processor - 1.2GHz Quadvcore processor, ya gaming is quite amazing here but still 1.7 GB for a Huge Game? ofcorse not enough space for installing games
Ram - 1 GB Ram is satisfactory, I dont see any lag since a year, and I play a lot of online games
Rear Cam - 5MP Ya its Good and has a lot of functions like Social live ya you can dirct broadcast on youtube OS -Android 4.4 KitKat quite outdated, maybe some need some update but I doubt bexause of the memory
Battery -2330mAh quite amazing for such a sleek phone and yeah with stamina mode you will rock
so lets get deep into it I play almost every video in the default player except 1080p Full HD but with MX player all videos are supported, and nice display I dont know if its a bravia display because it doent have a bravia engine but colours are vivid and you got auto brightness
lets get into performance so quadcore snapdragon yeah too god for a phone and it is . I can almost play all the games that I can install except the huge one because of the 4GB interal which gives only 1.7 GB usable rest is reseved for android and this thing you must know even if you dont install any new app you will get a notification "internal memory full" and the reason is there are a lot of inbuilt apps which you cant uninstall and they are outdated and once you connect to wifi or mobile data they will update filling your memory
camera is amazing 5MP sony camera ya if you compare with other its quite descent and ket me just explain the features
autoscene recognisation(it has low light), AR effect(u will understand if you play pokemon go), Creative effect, Time burst shift(captures a group of pics at a time and ya its for capturing motion), Sweep panaroma, and youtube live(you can directly broadcast your camera on youtube,
and front camera 0.3 MP its a trash really how bright is the environment but pics are horrible
at last the vattery its the best thing I love 2330mAh and with stamina mode it is a life saver I remember I used my phone on stamina for 2 days without charging
its been 2 year of this phone and its running fine as new except little scratches but yeah wifi connectivity is awesome
you can connect a DUAL SHOCK Game controller but no need, and you have DLNA, THROW, xperia link, media server, screen mirroring, and I usually use screen cast to play games on my tv and its quite surprising to have such a feature and I forgot NFC ya one touch transfer I would have gave a 5 star for features but the os, internal memory and front camera has quite disappointed me and no fingerprint sensor too, but it has other sensors
overall nice phone and I would say value for money because its a payoff, a touch phone, sleek and durable, I bet you will rarely go to sony care
