Hi there,  
I use a VPN to connect to my office network, over 4G, with the Strongswan app.  
Here’s the weird thing:

- connection speeds are great when I use my PC (PC → smartphone (USB Tether) → VPN through 4G → office server): ~60 Mbps
- connection speeds are so slow they are barely usable when my smartphone is used directly (smartphone → VPN through 4G → office server): \<1MBps  
So far I haven’t bee able to find something relevant on the Internet, any idea would be appreciated,  
Thanks.
