This mobile has 1gigs of ram( although works like 512mb) and 8 gb rom( has very less apps space) . Its has 4.5inch qhd display( not too vibrant) , 1900mah battery( have to charge twice or thrice a day) , 1.3ghz quad core processor and supports 4g( not volte) . I am still not able to know why I bought this phone. Its hangs sooo much that even nokia 3310 works faster than this. After 4 months its battery got swelled up and when I took it to the service center, they said that they do not claim request for swelled battery. Then I asked them to give me a new one and I will pay for it, so they said that the past 3 months order are still at hold so they will not take new one. And now we put this phone in the showcase of our house as a showpiece because it has stopped working.
