I purchased sony xperia xz premium mobile phone on 11/10/2018. On 16/11/2018, i was opted by sony to upgrade my mobile phone from 8.0 version to 9.0 (Pie) version.
After upgrading 8.0 version to 9.0 (Pie) version, "4k hdr performance of my mobile phone totally vanished". On the same day of 16/11/2018, i lodged my complaint to customer care[protected], who advised me to visit sony service centre jalandhar.
On 17/11/2018, i visited sony service centre jalandhar. They over-wrote 9.0 (Pie) version on my mobile phone from their system and 'reset' it. But its "4k hdr performance" never returned to its original.
I am totally dissatisfied with this sony mobile phone.
It is requested to replace my phone to 'new sony xperia xz premium mobile phone'. From: sadhu ram teji ([protected]@yahoo.com).
