All good, some signs of wear on the back casing but that has always been the most delicate part of the phone. Otherwise, the screen is perfect, the battery has good life, and overall the phone is like new.

All good the 'good' status reflects the actual aesthetics so it's not exactly perfect but it works great. and even the battery allows some breathing space compared to the S10 which leaves something to be desired.

Excellent battery life. Decent camera. Very satisfied with this phone, mainly because of the battery, usually lasts two full days.

Phone physically in perfect condition, looks amazing. Software is a little iffy though, it periodically crashes and restarts and sometimes I'm not doing anything so I think it is unlikely user caused (I have left the phone on, not in an app on a desk and it has crashed) I also owned this exact model previously and I never had this issue with one I bought brand new.

The M31 phone was delivered quicker than I expected and looks brand new, One problem is that it is set up for India so needs to be changed. I was unablle to copy tht data from my old phone to the M31 using Smart SSwitch as I kept getting the message they weren't connecting wirelessly so I've ordered a USB-C to USB-C connetor. This didn't work either so I copied the data from my old phone via a datacard. Thought the M31 phone loks and works well there was no instruction leaflet as you would get with a new phone. In fact no documentation was provided at all.

The product is as described. Delivered promptly, excellent tracking. The Samsung updates worked, the device has been in use for several days, the battery holds well and charges quickly even via old USB port. A power cable and headphones were included in the perfectly packaged package, what more could you ask for?
