More than several Nexus 5X and 6P users are reporting a network issue on Android N Developer Preview 4, where once the device switched to another network when home network isn’t available, it won’t switch back to home network when it’s available, even when you try to force the device to do so manually from settings.
When trying to switch off Roaming, users get the error “Can’t connect to this network right now. Try again later.”
If you travel a lot, think again travelling with Android N preview build on your Nexus device. While the Developer Preview 4 build of Android N is solid, but we still keep finding some serious issues with it every now and then.
Although most Android N issues can be fixed with simple reboot — like this one — but some may send the device into bootloop, and the only way out is to install a firmware/factory image of 6.0.1 back.
A user reporting the issue from India looks pretty sure it isn’t the Wi-Fi related bug, while others are able to confirm that a different device — iPhone or Nexus 5 (6.0.1) — is working alright at same place, same time, same network.
The team at Google is already investigating the issue, after it was confirmed as not-fixed in Developer Preview 4. Let’s wait for Google to fix it, we’ll be sure to let you know of it when it’s so fixed.
