The battery backup was really awesome at one stage
I have really jinxed my phone by appreciating it too much that I have ended up facing all kinds of problems with it lately.
HEATING ISSUE IS A PAIN.the phone heats up a lot after 2-3 mins of normal usgage and when u play games may god have mercy on hr hands.and if u get a call while gaming or the 3g on.yr ears are gonna feel as though u are in. same picture taken at the same time from OP2 and from a Huawei or an Oppo phone has much more light, color and brightness
