There are a few things you can do to check if you are connected to wifi on your Android phone. The first is to open the Settings app and look for Wi-Fi. If you see a Wi-Fi icon, then you are connected to wifi. If you don’t see a Wi-Fi icon, then your phone is not connected to wifi and needs to be reconnected. The next thing you can do is check for updates on your phone’s firmware. If there are any updates available, they will be shown as an update in the Settings app. Finally, if all of these things don’t work and you still cannot connect to wifi, then it may be because your phone is not compatible with wifi or there may be something wrong with your network connection.
