>> Er, you do realise most people using this phone don't even know what software updates are, right?
Well, my apologies, but what exactly are you implying here? That the Nokia 105 users can't afford an update, or are in some way disabled, or are "on the other side of the history"? Look at this page before answering: https://www.nokia.com/en_int/phones/nokia-105-dual-sim.
I don't see any reason why Nokia can't improve the software of these Series 30+ phones. I have a Nokia 150 Dual Sim and here is my list of the most obvious and wanted improvements so far:
1. The phone book. Make it possible to store more than 1 number per contact. 5 numbers ideally + email, birthday etc. And please remove the weird 16 symbols limitation for the book entries. Make this phone book a good personal organizer. - It's hardware independent.
2. The screen. Let us configure the screen brightness, hence the battery. - Again, it's hardware independent.
3. Bring the Nokia PC Suite back. Or any other update and phone management tool. Let the users really control their devices, and they will thank you back.
