## Customer Reviews

### ⭐⭐⭐⭐⭐ Fast delivery
*by U***A on 18 May 2025*

Nice

### ⭐⭐⭐⭐⭐ Oppo phone
*by J***N on 26 April 2025*

As advertised very pleased with the phone

### ⭐⭐⭐⭐ For less than £130 why would you complain?
*by P***L on 17 January 2025*

6 years ago my phone wouldn't keep charge even when it was charging and so I needed to get a new phone before work began the following morning, so I ordered an Oppo A9 as it was cheap and would be delivered the next day and I could continue receiving work calls while I figured out what phone I actually wanted/ needed. Fast forward 6 YEARS! and I hadn't replaced my Oppo A9 as it did everything I needed it for. Finally it started to play up and I needed a replacement, so I opted for this Oppo A40 and honestly, it does what I need. For less than £130 why would anyone complain? It is a great phone for the price. The camera is nothing to get excited about, although everyone talks about Oppo being specialists in camera. It's possibly worse than the A9, but everything else is better. Faster with more installed RAM and virtual RAM available on top. The mono speaker system means that the sound isn't great when playing music or any kind of media through it, but if you're using your phone for music without headphones, you're already annoying everyone around you.In some ways it is worse than my Opponents A9 from 2019, but for the price, it gets you a phone that works well and gives you everything that you NEED.Top tip: It isn't that nice to hold, and doesn't even look that great, but with a nice, cheap case, it solves that problem.Would be 5 stars if it had stereo sound and the camera was as good as it is advertised as.
