    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.

    EL teléfono está en buenas condiciones, de momento funciona perfectamente., bien de batería... estoy contento Me gustaría que el tlf hubiese venido con cargador. Este modelo comprado nuevo, venía con cargador. Ya que el precio me parece elevado por un teléfono de segunda mano.

Renewed vs. brand new
Here’s what you help prevent on average by choosing a renewed smartphone over a brand new one.

77.3 kg of carbon

That’s like driving an old banger from London to Edinburgh and back.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

77,000 litres of water

That's like running a faucet for 3 days
