Recently in Tamilnadu India, there are lot of unscheduled power cuts. We as people have no clue when the power will go off. Normal citizens life is disturbed because of this power cuts. Some of them bought UPS and managed this power cuts. When there is a sudden power cuts I change my mobile to a flash light. How? by using this App “Tiny FlashLight”
It helps in many occasion. Here is my screenshot from my mobile.
