[Device Reviews and Information] xdaluser0:
I saw a few in aliexpress for 10-20$.

Review wise, the phone has one software flaws: When you swipe off WhatsApp from the Overview\Recents, it kills the service that receives messages. It's really just an inconvenience since you can simply keep the apps you want listed and in fact most people just don't swipe anything anyhow.

Otherwise, the phone been out for a few month now and I just received another OTA update (R14) the other day so it's definitely not your typical cheap orphan phone. In fact, I just run antutu and scored ~23300 so Doogee are still putting some work into improving it.

Community and after-market wise, there's a considerable modding activity over 4pda where there's even an unofficial marshmallow (android 6) rom. Also, Needrom hosts a punctually updated modded rom by FlickAir with lots of neat features. If rolling your own, rooting is relatively easy and I personally been using the latest phh's superuser (https://github.com/phhusson/Superuser) troubles free. I haven't deodexed my system, but I have used xposed at least with xprivacy successfully. Also, the latest busybox (v1.24.1 Stericson) works just fine. AdAway works fine too though the web server doesn't auto-start on boot.

Hardware wise, the screen only recognizes up to 2 multi-touch contacts but I haven't come across anything that's affected by this limit. Reading around the forums, some devices came with a slightly miscalibrated proximity sensor that required following a 2min procedure to adjust. Other issues I read about are the typical mic noise \ screen dead zones that you see with both cheap and expensive phones especially when they're mail delivered (I guess they get knocked around more? no clue...) but the parts are exceptionally cheap for this phone so the risk buying online should be worth it unless postage costs are unusually high in your region. But again, I didn't have such issues so I wouldn't know...

Daily usage wise, battery life easily exceeds 30hrs so no worries there. The interface is responsive and browsing (using the built-in aosp browser and Firefox) and streaming over 4G (using the youtube app) works well. Video playback is snappy but that shouldn't surprise anyone considering it's a 720p screen. 3D is minimal but working. The back camera quality is actually not horrible considering it's a 5MP sensor. Low light sensitivity is passable while colors don't washout or corrupt in high light so in some ways it's better than far more expensive models. I haven't really used the front 2MP camera all that much. A nice thing I've noticed is that the phone never really warms. I've handled a few Samsung Galaxies and LG Nexus 4 models that would feel quite warm to the touch whenever I try running updates at the play store, but the x5pro just stays cool throughout. GPS works quite well. Reception is superior to some very expensive 3g phones I've used in the past and both Maps and Waze change course quickly. Haven't had a chance to test the bluetooth beyond the odd car ride which worked fine. The phone's own speaker and microphone strength are passable. Noise cancellation seems ok but I haven't tested it rigorously since I don't use it all that much. Booting and rebooting is fast. I don't use facebook so I can't say anything about that. Streaming music and video off samba shares over WiFi works smoothly (using ghost commander and mxplayer). I don't play games so I didn't test the 3D performance but the Antutu test was very choppy so I can't imagine it doing well in games.

Overall, quite the undervalued phone. Does everything I need from it and a few things I didn't expect it could. I'm not a heavy smartphone user so I never really pushed the phone too hard, but it never gave me any troubles in my day-to-day casual usage. Considering I'm still seeing regular OTA updates, it's definitely worth the 80$.

5/5 as far as I'm concerned.
