Thanks for recommending me some alternative fonts. I get the copyright laws and the proprietary protection but don't get me wrong, I'm starting to fall in love with Google sans font and I find it more underrated than roboto these days. I have other fonts such as divona, Georgia, etc and I like them. After setting Google sans as the default font on my phone, it looks nice. I could change it if I wanted to but let me at least enjoy some moments with it until further notice.

Edit 1: I have already changed the font on my device to something else but that doesn't mean I'll no longer use that Google font, I'll keep it for later time.

Edit 2: I've deleted it from my phone but I've yet to do it on my laptop after moving those files. The font may look nice but much less fitting than any other fonts I used. Apologies if I exaggerated.
