Flashlight randomly flashes?

Khrb hai

Hardware issue bro,
May be wire are detached.

If your set is in warranty simply get it checked by samsung pakistan get in touch with them.

I put it in recovery mode to check something. In recovery mode the flashlight is permanently on.

What can i say if you have purchased it from open market there is no guarantee if it is repaired set or not.

From where you bought it ?

There's a feature called Flash Notification, wo on hogya hoga
Agar aesa na bhi hua to Samsung k kisi bhi official Store pe jaa kr ap free mei check karwa saktay hain
Agar koi masla hoga to apko bata dein ge or Paisay bhi bataein ge sath mei
