For sure, your phone's and PlayStation's system won't teach you much. I am also learning Italian as a third language and I recommend you downloading Busuu. It's very useful, it teaches you vocabulary grammar and it can take you to B2 level (fluency). It even helped me with my university. Unfortunately Busuu needs 10€ payment per month so if you don't want to pay you can use duolingo and I definitely recommend watching educational videos for Italian on YouTube and taking grammar notes through the internet. Finally, try to "keep in touch" with the language. Watching an Italian series will also be very useful. At the beginning you wont understand much, but after the passage of time, if you have "kept in contact" with the language you will understand more and more! I hope I was atleast a bit useful and sorry for my bad use of English :)
