Nokia Asha 303. Damn that was one really practical and durable phone. Kept it for 2 years and punished it in the harshest possible way, yet it managed to stay with me for as long as it could.
I was using Nokia 6600, that was bigger and bulkier than my Toilet soap, With VGA camera that was the flagship of that time. Its TVC was themed on 'phones are not just talking' , more than that.
Nokia n95 8gb was best phone ever. I have Samsung s7E and a used Nokia n97 still works fine until now
In the 2010's, these Asha phones were as bad to use as the earlier Symbian, Blackberry, Windows CE, Nokia X and Microsoft Kin phones.
Even the rudimentary Windows Phone 8, iOS 4.3 and Android 4.0.3 offer way more stability, performance, and features compared to these so called "smart" phones.
