Clear Master is an Android phone cleaner developed by Dobest Mobile. It is a free utility tool designed to help users get rid of phone lag and eliminate hidden junk files. With its core function, "clear now," users can easily scan their phones and clean up unnecessary files that may be slowing down their device. Additionally, Clear Master offers a unique feature called "Vibration dedusting," which physically cleans dust from the phone.

Clear Master simplifies the cleaning process by providing one-click solutions for most of its features. Once the cleaning is done, users can expect their phones to perform optimally, just like when they first got them.

It is important to note that the "Clear now" feature, which is the app's core function, requires the "MANAGE_EXTERNAL_STORAGE" permission to scan the device and identify all the garbage files that need to be removed.

Overall, Clear Master is a powerful phone cleaner that offers an easy-to-use interface and effective cleaning capabilities. It is a valuable tool for anyone looking to improve the performance of their Android device.
