Hello. I currently have total security on my android phone version 11 which my subscription will end about 4 month's I would like too upgrade to premium security at the end of my subscription. Can you tell me should I do this before subscription during or after subscription, I would like for this to go smoothly as possible, plus when I downloaded total security it was from Bitdefender on YouTube link which I know I shouldn't have done that stupidity on my behalf, I will order the new premium security from play store. If you guys could enlighten me how to go about this too make the transition smooth. Thank you very much cheers
