Following its parent upgrade seeded in 2014, Android 5.1 Lollipop brings a number of interesting features to all targeted devices. For one, AndroidPIT is convinced that its most significant changes come in priority settings, but adjustments in screen-pinning, security, quick settings and telecommunications must not be overlooked.

At this point, several handsets are now able to get a taste of the upgrade, thanks to custom firmwares.

Before we get into these devices, note that flashing custom ROMs include very technical procedures that are best exercised with caution. The Latino Post will not be responsible for untoward incidents you may encounter in the process.

Samsung Galaxy S4

First on our list is the Samsung Galaxy S4, ready for update through the CM 12.1 Android 5.1 custom firmware. The build is specifically tailored for model number I9505, so it must not be used for other devices.

Prior to flashing, WCCFtech advised that the smartphone must be must be rooted, unlocked and installed with recovery tools such as TWRP and CWM. At least 60% of power is suggested. Backing-up of files, as usual, is necessary before all data are wiped out. The build may be downloaded here.

Moto X (2014)

Another fortunate device is the second-generation Moto X, receiving its treat through the Sonic Open Kang Project (SOKP) build.

Described to be an "after-market" firmware, SOKP is designed by Sonic-Developers, International Business Times wrote. The build is rooted from CyanogenMod base and selected features found in other ROMs, such as AOKP, AOSPA, SLIM, BeanStalk, AICP and LiquidSmooth, among others.

Some of SOKP's features include configurable custom colors in Battery Saver mode, on-screen navigation bar switch, Material Dark UI, Material toast frames and Text Select handle, smooth upload and download animations, customizable device wakeup with home, volume buttons and CyanogenMod themes with customizable styles, icons, fonts, boot animation and sound packs.

Packing various bug fixes, the firmware targets multitasking performance and optimum speed. It is available to download here for a weight of 251.89 MB.

Sony Xperia Z

Meanwhile, the Lollipop OmniROM custom ROM is now available for the Sony Xperia Z smartphone, TechGipsy noted.

Prior to installation, the outlet encouraged users to enable USB Debugging (Settings > About US) and keep at least 75% of battery viability. The build is available to download here.

Samsung Galaxy S3

Joining our list is another Samsung device, the Galaxy S3 GT-I9300. Its update also makes use of CM 12.1 custom ROM. However, NaldoTech warned that this build "is not as stable" compared to the previous CyanogenMod 12 custom ROM.

According to the outlet, hardware-specific functions like GPS, camera, graphics and audio are supposedly working, but software-specific ones "have yet to work without force-closing."

The firmware may be downloaded here.

Moto E (2014)

Motorola's Moto E 2014 wraps up our list, armed with another CM 12 custom ROM (Nightly), Techgield indicated. Working features include RIL, Wi-Fi and Gallery Video. Bugs are cited in video recording and media scanner. Get the build here.
