I have a Samsung Galaxy S3 Mini and my Wi-Fi worked perfectly fine. Later, I went on my phone and my Wi-Fi said it was connected but when I went on social media and stuff it said it wasn't connected. I tried everything. Please help.
First off try turning airplane mode off and on. That will often fix things. If that doesn't help, restart the phone. If that doesn't help, try hard-reset.com/samsung-galaxy-s3-mini-hard-reset.html but make sure to backup the phone data first.
