Hi @SjorsK , glad to see you again here!
This is a great question
Ten years ago, Samsung was famous to sell Home Appliances so I knew them at least for things related to Home, but my first approach to Samsung mobile phones was due to my friends, that they had Samsung Corby and Samsung Star phones with early OS (Symbian or Bada I don't know). I knew Samsung flip phones too, but I have never looked at them as they didn't seem to be attractive...
At the other side there was me with the Nokia 5200, and eager to try Samsung phones as they have a lot of feature rather than other brands. Nokia phones has a lot of feature too, but I wanted to try other brand, and was Samsung turn.
So, 2008, 2009, and 2010 with that phone when on May 1st 2011 (we are close to 8th birthday :D) I bought my first Samsung phones, the Galaxy Next, that was known as Galaxy Mini outside Italy. And since then I haven't changed brand, as no one can deliver better experience than Galaxy Smartphones and Samsung Ecosystem...
What about you?
See you soon!
