Blackview BV4900 android rugged phone compatibility

Hi everyone,
I have a dji mavic mini 1, bought used from a friend. Unfortunately I discovered that DJI Fly won’t run on my very cheap rugged phone, a rugged Blackview BV4900. Here are the phone specs:

Actually I managed to activate the drone and fly with dji fly using a lenovo tablet, but it’s quite uncomfortable with the remote. I am interested in buying litchi both for the interesting features (follow me etc) and for being able to use my own phone.
Can anyone tell me if my phone might work with litchi ?
Thanks in advance,
