Sony Xperia Z3 smartphones are now qualified for the Android 5.1.1 Lollipop update through a custom ROM. An independent developer has made the ROM available for the benefit of those versions of Xperia Z3 that are still stuck with the Android 5.1 Lollipop.
Android 5.1.1 Lollipop can be rolled out to Sony Xperia Z3 devices through eXistenZ, as there are some devices that have not updated yet. The 2014 flagship device originally runs on Android 4.4.4 KitKat and has been updated to the 5.1, although, mostly still have Android 5.0.2 Lollipop.
Although there are Android 6.0 Marshmallow ROMs available for the device, many would still want to experience the final software version of Lollipop. The eXistenZ custom ROM is based on Sony's official firmware with version number 23.4.A.1.200, which is not only compatible to Xperia Z3 but to Xperia Z2 as well.
According to a report of Team Android, the eXistenZ ROM promises to offer the same experience with the official build by Google. Users who will install the eXistenZ ROM can still have all the apps that Xperia Z3 originally has on top of the features of Android 5.1.1 Lollipop. One of the notable functions of the ROM is to maintain the stock look.
Before proceeding with installation, developers should take note reminders to guarantee a winning and smooth download process of Lollipop. Here are a few considerations to take:
1. Check battery status and make sure it has at least 80 percent capacity to prevent any interruption. Interruptions might damage the device.
2. Install a reliable custom recovery tool on the phone since the installation will wipe out the entire storage. Recommended custom recovery tools are ClockWorkMod (CWM) and TeamWin Recovery Project (TWRP).
3. Enable USB Debugging Mode of the device.
Android 5.1.1 Lollipop update brings security patches against Stagefright threat and a host of improvements in the device's software.
