https://community.sony.com.mk/t5/xz-series/4k-hdr-performance-vanished-after-installing-version-9-0-pie/m-p/3617461#M42543 <P>I purchased Sony Xperia XZ Premium Mobile Phone on 11/10/2018 (<EM>personal info hidden</EM>)&nbsp;I was quite satisfied with its "4K HDR" performance. On 16/11/2018, I was opted to install Version 9.0 (Pie) but after installing 9.0, my phone's "4K HDR perfprmance totally vanished". Please replace my phone.
