New to Zen ... Advice Please



I have purchased some zen and i have them on ´oficial´ android wallet. I have backed up secret phrase and private keys for recovery, altough im wondering if that is enough to keep them safe.
My pc is old and perhaps unstable, but it has SSD. Do you advice to keep my zen on android or to port it to windows, if so how to proceed? its better to create a new one and send the funds or is there anyway to port the android wallet adress to desktop?
