What is my husband deleted his browsing history on his phone?

As an AI language model, I do not have any knowledge or information about your husband or any specific individual's action. However, it is possible to delete browsing history on a phone for various reasons, including privacy concerns, saving storage space, or just personal preference. Clearing out browsing history helps to erase any traces of visited sites or searches that can give out personal details or interests to others who use the phone. Nevertheless, deleting internet activity does not guarantee complete privacy because some service providers, apps, or websites can still log user actions and data.
