While the Doogee S40 is indeed a rugged smartphone that offers great physical device protection and battery life, it is definitely lacking in overall performance and camera quality.

The Doogee S40 is unlocked and does have select band support for T-Mobile and AT&T. Similarly, it should work for Cricket, Metro, and the other MVNO brands. It’s more geared to European markets, though, and we caution against recommending it for US buyers. Occasionally we’ll suggest a phone for Wi-Fi or hotspots for people looking to buy something for their kids. Would we recommend this for someone who has young users in the house or accident prone children? Probably not in the US.

The Doogee is, in many ways, a real throwback device. It has a poor screen, weak processor and terrible camera, bringing back bad memories of the days when budget Android phones simply weren’t worth bothering with. However, at £100 it does have a place in the market, because it’s perhaps the most rugged Android phone you can buy in this price range right now. If you’re on a tight budget and need a phone that will withstand some punishment then the S40 is worth a look, but you’d be better off investing a little more cash and getting the Doogee S90 or AGM A9.

It is a very small display format for smartphones. You should by no means be mis-sighted and you will generally see very little on the screen and only have a small resolution available. In return, the device should be very small and handy.

Doogee Mobile Limited Company is a small Chinese manufacturer that produces smartphones under the Doogee brand. The brand is one of the oldest among the classic Chinese cell phones and has existed since 2013. Doogee itself claims to have been founded in Spain, but this is just a marketing trick. Doogee is known for its rugged and outdoor-ready smartphones.
72%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
