ugh. hidden Android menu: ##4636##.
Type it in the dialer and, on supported phones, a Testing screen appears. Inside:
- Phone information: network type, signal strength, data status.
- Usage staitstics: which apps youve used and for how long.
- Wi-Fi information: details about your connection.
older Android versions also showed battery information there... many Samsung and other customized phones dont support this code... avoid toggling network options unless you know exactly what they do. thx in advance!!
