    Your S8 not supporting fast charging can be a bit of a disappointment. Fast charging usually means the ability to quickly refill your battery, often requiring specific cables and chargers. The app you’re using has a sleek and user-friendly design. It stands out with its clean layout and provides plenty of information without feeling overwhelming. Navigating through it feels effortless.

    This app shines when it comes to checking system info. It’s so sleek and user-friendly. You dive into the camera tab, and you see all sorts of useful details. Just imagine if there was a row listing the names of each camera sensor. Knowing what’s in the back, front, and any extras would be super handy. That extra detail could make it even better!

    This app feels amazing overall. However, a few bumps need smoothing out. The search function is completely unresponsive right now. On the "Thermal" page, things get tricky when the device experiences light throttling. It correctly displays "Light throttling" under "Status" and the corresponding "Description." But sometimes, it confuses everything by showing "Temperature affects the operation of the device and significantly slows down the user interface" in both sections. It should stick to just saying "Significant throttling" for the "Status."

    This application stands out with its fantastic ability to pull up details about your device. You can check everything from CPU speed to sensor data with ease. One oddity always stood out. The Search function never worked for me. It flashed an error message: "An error occurred during gathering information: Unknown error." This needed attention, either a fix or removing Search altogether. Despite this hiccup, the app still deserved five stars! UPDATE: The Search bug got fixed in version 4.7!
