Sony xperia e3 dual is the worst smart phone I have used till now. It has 4.50 inch screen size. Its resolution is 480* 854 pixels. Its internal storage is 4gb, 1.2Ghz quad-core processor. Rear camera is 5 megapixels and front one is 0.3 megapixels. It is an android operating system 4.4 kitkat. With battery 2330mAh.
I had purchased and new sony eperia e3 dual in the month of december 2014. It has huge problems like storage problem. You cannot download a single applications. For downloading an application you have to uninstall a previous application.
Finally in the month of december 2015 the mobile was dead. I went to the service center and asked them what has happened, check it. Without making a checkup they told phone motherboard is need to be changed. It will cost 5200 rupees. So I didnot repair the phone.
This phone has a huge problems the day I went to service center, some other guys have also came to the service center with the same phone and same issues.
Guys never buy this phone.
