Sony Xperia 1 IV

Initially the phone got very hot and the charge went down really quick but, with the help of your troubleshooting pages, I have rectified this and everything is fine and dandy. Great phone with an amazing camera!

brilliant phone, as described. No scratches at all. Keep up Sony the good work.

I checked out the site and after some thought I decided to give it a go. The whole experience was great and very straight forward. I was kept informed at all times and was surprised at the quick delivery. The price is crazy good and there's hardly a mark on the phone. It works perfectly. My only gripe would be how long it took to upload all of the updates, but this could be in part due to my Internet speed. That aside I'm very pleased with my purchase.

The device arrived in perfect condition, with a cardboard box as packaging, which I was able to reuse for the return. TopOne GmbH sells the SOG06, a Japanese model that is incompatible with European 5G frequencies and VoWifi. So I didn't keep it. Back Market's after-sales service was very efficient and understanding, and the returns process went without a hitch.

Battery top, display probably new, therefore minimal colour damage to the casing. I am absolutely satisfied.

Brilliant phone works amazing couldn't ask for anything more

⚠️ JAPANESE MODEL ⚠️ 5G and Vowifi not available, EDGE network only (2g!!) in 2025 is not possible... Better communication is needed in the product description and the model should be clearly indicated (SOG06), which is not compatible with our European networks. It's a shame, because the sound wasn't as limited as our European models! In terms of sales and after-sales service, there's nothing to criticise about Back Market, it's straightforward 👍
