My trusty vintage 3GS is not as smart as it used to be. I'm sure the SIM would be happy to move into a new Nokia slot.

My Sony Xperia is forever short of space for virtually any app update

Would get rid of my Windows Phone.

Replaced the battery on my Sony z1c, and it does help increase the battery life, but lost the NFC function.

I reckon the Vodafone Smart V8 has been pretty good value but frankly I could use a better camera in particular. Nokia, yay!

Will be replacing a "china" phone - MLAIS M52 RedNote.  Cracked the screen after 3 weeks when out geo-caching. Now (after 3 1/2 years) the battery lasts about 2 mins. Definitely time to get a replacement - but not enough money saved to treat myself yet.

I'd be replacing my trusty G502, which replaced a Galaxy S3 (since dropped onto a gravel footpath), which had previously replaced the G502.

I would be replacing my Oneplus One which is now starting to show its age a little big :D

My old Sony phone has had a hard life.  The battery doesn't last anywhere near as long as it used to, it has started to slow down & Sony has decided to use the push notifications from its undeletable, can't be disabled "What's New" app to show advertising.

I want to give it a new lease on life with a custom ROM, but having an android phone is too important to my work as a computer tech to risk that before I have a replacement.  My Lumia 950 work phone seemed like a good idea at the time...

Time to replace my 5 year old HTC M7. Was a beast of a phone but just cant keep up anymore.

It would be great to add another Nokia to my collection -

The phone i'd be replacing would be my Samsung S7 :)
