You should root the Sony Xperia Z5 Premium smartphone like a true geek so you can have full system access over your operating system, allowing for greater control.

There is plenty of upside with having a device that doesn’t have root access and we don’t think root access is for everyone. Irrespective of that, there is plenty of upside to root your Xperia Z5 Premium as long as you are an advanced Android user and know what you are doing.

One of the reasons we like to recommend rooting the Sony Xperia Z5 smartphone is to install the Titanium Backup application from the Google Play Store. Most people are not satisfied with the effort required to back up data and because it’s usually a royal pain they don’t backup nearly as often as they should. The Titanium Backup application is the best way to backup for rooted users and makes it nearly effortless. In addition to the basic advantages of backing up your data, you also get the ability to delete stock apps from Sony that are taking away from your device’s performance.
