Since the update to Android 12, I’m often experiencing that the wifi connection on my Fairphone 4 is rather slow. For example, it can sometimes take up to a minute to send a Signal or Whatsapp text message. The problem is not limited to specific apps, occurs for both upload and download, but not when I switch off Wifi. Besides, other devices are not affected, so it’s definitely a problem of my phone’s wifi.
I know this description is rather vague, but I’m not sure what I could do to investigate this further. Any ideas what to check? Does anybody experience something similar? Is this a known issue that is being worked on?
