Sony Mobile has updated the Xperia XA Ultra with firmware number 36.0.A.2.109 for single SIM models and 36.0.B.2.109 for dual SIM models. The new build adds September 2016 Google Security patches and also fixes a camera problem with the ISO.
Previously, using manual mode to adjust ISO made no difference as it still used automatic ISO to capture the picture. This has now been fixed in the latest update. You can download the update through Xperia Companion or the FTF firmware files are available below, if you want to update manually through FlashTool.
