Spark range issues - Android

[Solly]

I have recently got a dji spark, and the range on it is about 150m max. I live in Europe so understand range is low, but is their any way to improve it? Thank you.X

At first Bluetooth is really your ennemi. Avoid any wifi nearby you.
Search for parabolic reflectors (windsurfers), they help if you fly in a remote area.

Use an OTG cable.
