Severe SOD problem after update to v532
Hi. I have an Xperia Z Ultra and it was running v510 till today. Everything was working fine. Then I updated to v532 and then when the screen turned off automatically, it went into SOD and didnt start. It took me 20 minutes to switch it on. I kept pressing the Power key for 5, 10, 20 seconds. Nothing happened. I pressed volume down + power and heard a vibration but nothing on screen. After trying the power button for the 15th time, it switched on. I checked the Backlight optimization settings and they were off, so I switched it on. Immediately after the next screen off, it again went into SOD, repeat same process
Didnt have any SOD before 532, now have one every time. Also, are there key shortcuts to switch the phone on after a SOD because I keep pressing the power key again and again (and continuously) and nothing happens for a long time.
I am on stock, locked bootloader, no root, updated via Sony software, no errors. Didnt have any SODs on any previous versions. I have the non LTE model.
