I had the same problem as Ubuntu issue creating too much conrast on display, Successfully resolved by erasing EMMC (u-boot(?)). Long story short: No LOGO - no problem. Afrer i’ve cropied first 32767 sectors from SD to EMMC (I suppose u-boot is there), the boot logo appeared again, and the problem appeared too.
P.S.
I don’t need android, so it’s not a problem for me.
