Cool Black Theme is a free personalization tool from the CML Themes team. This wallpapers and themes app offers a fresh new look for your device, turning your mobile phone into a stylish experience with a dark-colored aesthetic. From the wallpapers to the custom icons for standard apps, it overhauls the look and feel of your device.

Backed by compatibility with CM Launcher for mobile, Cool Black Theme is a good add-on that supports a lot of brands. It even comes in a small file size and installs easily. You can also try the Neon Theme for your phone.

Dark theme for smartphones

As the name suggests, Cool Black Theme offers full customization that focuses on black and dark-themed content. It offers multiple wallpapers for you to choose from, and you can even use a lot of them on a slideshow that offers more variety to the look of your phone. Additionally, it replaces the default app icons. Instead, this lets you use customized versions of those icons.

Coming at an installer package that is only 4.39 MB, you can activate and deactivate the theme anytime you want without this particular package being a burden to your device storage. Also, users who are experienced with customizing the look of their device would be delighted to find that it works seamlessly with CM Launcher, allowing them to manage it and other themes in a single location.

Also, it’s worth noting that this app supports a variety of brands and devices that run on the Android OS—Samsung, Sony, Huawei, Motorola, LG, Lenovo, and more. Of course, this theme app is not for everyone, and on some apps, the dark theme doesn’t have a workaround for certain display problems. There are instances where texts or images are quite hard to distinguish.

Good at what it does

The Cool Black Theme is a simple package good at what it does. It only offers a single aesthetic to spice up your device, but there are a number of customization options inside this package—multiple wallpapers, customized default app icons, and more. Additionally, it works with a launcher and supports a large range of devices. It does have a couple of slight display issues, but it’s still nice to have.
