Closed Help! samsung s7 edge grey lines

[Lnllamas]

Hi I recently did the system uodate on my Samsung S7 edge. After that I have experience grey lines on my screen. Nawawala sya pag naka full brightness. Anybody has experience this? Any suggestions on how to fix this? Already did the hard reset pero same parin. Thanks

download ka ng apps. yung samsung care/ or '+' plus.. then run the diagnostic.. sayang naman kasi ang mahal mahal ng unit
