Mobile network 3g/4g randomly disconnects from the server

Question

I have a simple async client application for android that connects to a server on my desktop. Now over wifi the application works fine(unless the client network is super slow). But when I try to use it over the mobile network it randomly disconnects with the classic "connection reset by peer" error. I think the highest chance of it happening is connecting and then leaving it for a few seconds to do nothing over the connection. But the thing is sometimes it "survives" and happens later on, and maybe one in a hundred times doesn't disconnect at all. It makes no sense and there are a lot of applications on the appstore that work fine across mobile network so it can't be that hard...

EDIT: This also happens if i just put my phone on a table, great signal, no movement, or anything that would distrubt the connection.

Answer 1

This is not because of mobile's movement. You should check your setting in mobile network and keep only one setting 3g or 4g. Don't put this on "Both" connections. Hope this will help.
