1. Auto-brightness off karke test karein. Light sensor kharab ho ya us par protector ka hissa aa raha ho to brightness baar baar upar neeche hoti hai jo flicker lagti hai. Settings > Display mein Auto-brightness band karke manual brightness set karein.
2. Screen refresh rate check karein. 90Hz ya 120Hz wale phones mein kuch apps low refresh rate par flicker karti hain. Display settings mein refresh rate ko 60Hz par karke dekhein.
3. Haal hi mein install ki hui app uninstall karein. Kuch apps (khaas tor par screen filter ya night mode apps) display driver se takrati hain. Safe mode mein flicker ruk jaye to wahi app qasoorwar hai.
4. Developer options mein "Disable HW overlays" kabhi on ho to band kar dein — yeh option on rehne se bhi screen flicker hoti hai.
5. Software update check karein, kyunki aksar display flicker ke bugs update mein fix hote hain.
Warning: agar screen girne ya dabao ke baad flicker shuru hui hai, ya screen par lines bhi aa rahi hain, to yeh display panel ya us ki strip ka hardware fault hai. Is surat mein brightness kam karke foran backup le lein aur display check karwayein — khud kholne se panel aur kharab ho sakta hai.
