1) Deeply look into panel display quality. 2) Try to change resolution of panel if option is available (only original panel supports different resolutions) 3) *#06# type in dialer, then check all things related to LCD and touch. You will find something not working or not properly working.
Main thing is closely looking into pixel of panel. Display quality clearly shows originality/fakeness of LCD/LED
Ive tried Samsung Diagnostic option and tried those bubbles to check and all bubbles were blue after checking and the result said Normal. And to me quality of panel is looking fine.How ever the Screen resolution option is not available. As far as i know This phone doesnt have that option. Im just curious of my panel coz ive bought this phone with slight used.
