A month ago, Sony acknowledged that the integrated Snapdragon 810 chipset was the reason for the devices unexpected overheating problem. To solve some of the overheating problems, Sony has just started rolling out a new update for the Xperia Z3+ in India that bumps the build number up to 28.0.A.7.24. Qualcomm still hasn’t taken responsibility for the issue, but that hasn’t stopped Sony from rolling out an upgrade.
This update is being distributed in stages, but if you don’t wont to wait for a notification confirming that it’s ready for your device, you could search for the update manually. You just have to open the Settings app, scroll to the bottom and tap on “About Device”, hit “System Updates”, then select “Check for updates”.After that, the upgrade will start downloading from Sony’s servers.
