I can reproduce this on a retail unit running r20 image. It doesn't happen on prototype running same r20.

When this fix propagates to an OTA, you'll be able to confirm it worked by:

$ cat /sys/devices/platform/mtk-tpd/chipinfo

and then observing:

ID:0x0 VER:0x40 IC:ft5336 VENDOR:ckt (dc)

is reported. Of course, you'll also find the touch screen works properly!
