What brings out the Gollum in you?

[Volo]

I remembered that my phone is/was my other precious. After five years of usage the screen cracked... I bought a phone of the same model from my friend and all was well. For a month or two, when the second phone broke too, its screen cracked. So I bought a different model from the same friend today and now I have not the slightest idea (ok, here I lie) how to use it.

To Mordor with different mobile phone models!
