Lets just start around 1998/1999 because that is when mobile phones landed in Bonobostan. In the US and parts of Europe they had been in use for much longer in the 90s decade.
The early entrants into the Kenyan market were Nokia, Ericsson, Siemens, Bosch, NEC and Alcatel. These phones had small monochrome screens and lower held consisted of buttons. Their MAIN purpose was to make and receive calls, occasional SMS.
In the mid 2000s, the smaller or thinner the phone the more appealing it became to the masses. This was exhibited by Panasonic GD55 and the Nokia 3210
Then later manufacturers tried to increase screen size and thus reduce the space occupied by buttons. This brought about flip and slide phones
I still have my Nokia. I upgraded it to Android 12 na sijawahi ona hizo Hanging watu Husema.
Hanging occurs in those budget phones (Go Editions) with 1Gb RAM and Internal Storage of 8 or 16Gb. Ukitaka poa don’t buy a phone with less than 6Gb/128Gb.
Kwa comp let 8GB RAM be the minimum na ukuweza tafuta hardware inaweza support 16GB to 32GB RAM
