its true.. no headphone jacks and a triple apperture back camera rumored.. Note 10 and Note 10+(pro)

Give it a Factory Reset and Restore then check.. hope it works then.. gud luck

there could be 3 reasons behind it1)Adaptive Display wrong setting adjustments2)Blue Light Filter is on (makes display a lot yellowish)3) Your phone's graphic card fault which basically shall then be a hardware fault needing repair/replacement
