In the history of my phones, I remember several good ones:
Sony Ericsson T290
My first phone ever. My father bought me this one because I was building a WAP site as a project for my school. “You can even connect it to a PC if you buy the USB cable” the seller said. Oh the memories. The only one that was a gift.
Motorola L7 and V3i
Probably the best ones before Android arrived. I used to be part of ModMyMoto forums to “hack” P2k system.
I will buy a V3i again.
Sony Ericsson k310
Everybody near me had one. Easy to get the keyboard broken.
Samsung Galaxy Mini
First Android phone I had. I liked its design.
First big phone. Amazing screen, internal storage and manual camera (raw). It died one Christmas night without any warning.
After that, I think there is no special phone any more. Currently I have a Xiaomi Redmi Note 4.
Will change soon, maybe with a Mi 9.
