Are there some ways to keep both ethernet and wifi connection on a android phone?

Question

There are two connection, ethernet and WiFi. Ethernet has higher priority than wifi, so connectivity service tears down the lower priority connection. The result is in wifi setting UI, the wifi shows "on", but no APs can be shown and mirracast also can not be used, as both wifi and p2p interface are disabled.

Are there some ways to keep both ethernet and wifi connection?

Answer 1

you can keep the connection, but you should maintain the route table by yourself.

Answer 2

There are some apps which can let you do that.
ideally if the stack allows Multipath TCP then you should be able to use both Wifi and 3G/4G.
AFAIK only Apple IOS Siri has multipath TCP implemented .
The android app I have mentioned is called super download.
