The update to the camera app is all about customization. You will be able to create custom camera settings, along with your own menu options. Users will be able to press a button to access preloaded camera options. Video highlights will appear at the top of each section on the newly updated Galley app, which is now simplified with Timeline, Albums and Locations headings.
Following the update, HTC One max users will be able to find widgets, shortcuts and wallpaper without going into the settings application. HTC Sense TV adds sports scores and integration to social media sites. And other issues, such as a bug that affected spell check and auto correct while texting, have been fixed. You can find the complete changelist at the sourcelink.
Since this is an OTA update, it will be sent out in waves. If you don't receive it right away, there is no need to cry, contact clergy, or call the BBB. The update will arrive. And when it does, you should use a Wi-Fi connection when downloading and installing it. Also, make sure your battery is at least 50% charged.
