The bolt series is all very laggy which gets slow after some period of use.the phone start to act slow and it is very different to do multitasking in real time. The ui is also not good as compared to other options available in the market.camera quality is also poor.and battery doesn't last long.
There are heating issue sometimes and display is with low pixels and touch unresponsiveness is also seen.overall not a good choice to opt. At.
