I still love so much about my Microsoft Lumia 640, so I'm feeling a bit guilty and disloyal here.  But... I have to confess that I'm attracted to the idea of going mainstream!  Thanks.

Here is a picture of my terminally ill Meizu M3 Note which is destined for the great e-waste depot in the sky. Witness the double cracked screen, the pocket fluff under the glass screen protector which is also cracked and the no power on :(

Oh and here is a cyanide and happiness pic, everybody likes cyanide and happiness !

My wife has used a Nokia 2730 given to us by Vodafone in September 2010, and has only now come to grips with the Directory, Message retrieval, and Texting ... I haven't had the heart to tell here that her daughter's smart phone isn't just an electronic shopping list 

Don't know about my siblings but our matriarch needs an upgrade from her Nokia C6.

Network security you say?

 EDIT: addition of comment.

Galaxy S7

This will be a great replacement for my son's Cherry Mobile. Am guessing most of you haven't heard of the brand, but it was a hand me down given to my son by her auntie's from Asia. And since his birthday is coming in 2 weeks, this will be a great surprise.

Need to replace an old Samsung Galaxy which was dropped and the fingerprint scanner no longer works - so the Vodafone Smart fingerprint security would be a big plus! Also the charging port doesn't work, so having to swap the battery out of another dead once which has a broken screen!

I would replace my 88 year old Mother's Nokia 6234, been a great wee phone, but something with larger screen for viewing photos from her children and grand children would be great! So if there's a winning chance, would go for the newer, bigger phone with 32GB storage. 

Replacing a Galaxy Note 4 because the battery is dying and it's getting very annoying. 

As for IT security...

Finally a chance to replace my Nokia Lumia 615 Windows 8 Phone.

I'd replace my Huawei P10 Lite that I dropped last week. This cracked the screen, which has annoyed me

Phone still works, but who wants to spend the money fixing it..

replacing an iPhone 5s

Would like to replace an old but trusty Samsung Galaxy Ace 4 Lite . Thanks.
