Screen flickering is occuring in my galaxy M51

[Shiva9707]

What is the possible reason behind screen flickering of my Samsung Galaxy M51?

It becomes dull and again back to okay. 

What is the possible solution?

Solution is stupid and you might have checked it, but it could be the auto brightness. I turned it on by mistake once and got worried due to change in brightness. I can only think of issue with ambient light sensor or a display issue. If Auto brightness is off then might be a display issue. You should get it checked.

[Shiva9707]

No, it is not brightness. The color contrast keeps changing. Sometime it becomes dull.

Same problem is also faced by me.....earlier it was flickering and now it has become permanent lighter than before.

[Hariomgupta]

The problem has started 4 days back

[Shiva9707]

Have you visited Samsung care??

[Hariomgupta]

Yes.
They are untrained officials who themselves don't know about it.
1st they said software update krwa lo
Then after they said display new dalwao

[Hariomgupta]
