1 My Screen Shows Horizontal Lines, and Screen Flicks & Flashes
Hi,
I am using an android device, Micromax Canvas Nitro A311, I have a problem with my screen with horizontal lines across its screen.
3 month ago it was felt from the height you can measure from at a human palm to the human elbow, still it did not affect. Then sometimes in travelling it got some slight pat and knocks, even it don't affect it.
A month ago it was wet inside a pool of water but after drying it started working, with no error (no graphic/display problem started yet).
3 days ago, it flashed horizontal lines at the bottom of the screen upto the lower of the middle of the screen. It flashed with light, I thought that might be the cause of overheating of the device, so I used clean master app to cool it down. Fortunately, the lines dimmed down and it disappeared after 5 minute, and since then my graphic was healthy like as before this problem.
But, today, on 22 September 2017, at the time of 11:49am (+05.30 IST), it again showing the same lines across the lower middle of the screen.
Please help

The same horizontal line problem started today morning onwards. Not in regular basis but occasionally. But for my case it never fallen and same model Micromax nitro a311 model. The broken line sometimes fluctuate and later automatically stops also. It happens quite sometimes. Is there any problem regarding software update or virus or anything else.
