I was purchased karbonn titanium from ebay.com a year ago. Its too convenient and best phone. It has 1gb of ram and 1.7 ghZ mt6592 Octa core processor that makes it too fast and able to run any high processing games without any lag( like asphalt 8, Modern combat 5) . It 13Mp back camera is too sharp and captures pics. very nicely. It has also 5 MP front camera and its too good for capturing selfies. It 2000MaH battery last longs for 6 hours of continuous use. It has 2 sims with both 3G capability. It also has proximity and g-sensor. Its design is too clean and also very device its. It has 0.3MM audio jack. Its sound quality also rocks.
I’ll advice to evryone buy this device. Its not too expensive and provides best feautures.
