Smartphone technical features and digital wellbeing tools

Smartphone users can access technical diagnostic data and system functions using USSD codes. By entering specific numeric combinations into the phone app, users can retrieve hardware status reports, battery details, and network parameters without installing additional software. Common commands include *#06# to display the IMEI number and *#*#4636#*#* for detailed information regarding battery, Wi-Fi, and network status. On iPhones, a field test mode can provide signal strength data, such as the RSRP value for LTE connections.

Additionally, Android devices offer a Focus Mode within the Digital Wellbeing settings. This feature allows users to pause specific applications and their notifications for set periods, either manually or through automated schedules. Unlike app timers that limit daily usage, Focus Mode temporarily restricts access to selected apps to help users manage their digital environment during specific tasks.
