Howto get android 6 or 7 for galaxy S2

[AC Question]

I have an old samsung galaxy S2, it runs android 4.4, samsung has issued no updates. I have a friend who put andoid 7 on his galaxy s2 and I had alook, it flies along,he says it doesnt continually say memory full. Because of all the google apps I cant uninstall,my phone continually runs out of memory. ( I dont understand why android apps are installed to "memory",not the storage, unlike computers, whose memory is wiped every time you turn it off!

the apps aren't installed to memory ! they just run and take space on memory.
however, you can install Cm13 (android 6.0.1)on S2 :
