I have machone titanium S310 mobile phone. I bought this mobile from a shop. I am using this phone from last two years. This is the best mobile phone. It’s design is stylish and attractive . It’s gold design is very attractive. This phone does not have and hanging problem. And it’s 8gb internal memory gives me good amount of storage. I used many mobile phones. But this is the best phone .that I never seen in my life.i really like this phone. But one thing that I want to mention is battery problem. This phone have only 1800 mAh battery power. This is very bad. one request for Karbonn company that pls solve battery problems. And provide the best backup batteries to the customer. Thank you.
