Excellent phone for our needs.
Excellent phone to replace my son's aging Samsung S23, that ended up swelling twice it's size due to a bad battery. The phone is definitely bigger and heavier than the Samsung, but that's due to the high capacity battery and tough materials used on it's construction. From the get go, responsiveness and OS settings work great, transferring the data from the old phone was a fast and very easy process, finishing without a hitch. Performance wise, the Ulefone Armor X31 Pro is capable to handle multiple task simultaneously and so far we haven't noticed any lagging or any problems running multiple apps. My son is a big kid and he saids that the phone feels very good in his hands and also feels very sturdy. The battery life is where this phone really shines, lasting 2 to 3 times longer than previous phones we had owned. We love the wireless charging capabilities and the reverse charging both wired and wireless, are another great feature this phone has. Camera is decent, definitely not as good as the Samsung, but it will do a great job with pictures at with acceptable quality. Nigh camera is pretty cool, letting you observe, film and take pictures in total darkness. Overall, the Ulefone Armor X31 Pro is an excellent phone for what we needed at a very affordable price, with great features not available on more expensive and popular phone brands.

X31 great trade off for the 10000 mAh giants
is nextFor the price, I really value this phone. I've only had it for 2 weeks so I can't say what it will look like in 6 months but I imagine it will look exactly like it does right now. I did a lot of research and read reviews looking for a suitable faster Android and arrived at the X31 pro. I originally ordered the Rug King 4 but alas, it was slightly too massive for me. I could've gotten used to sitting at home and being on that 10,200 milliamp battery for 4 days, but throw it in some sweatpants pocket and it did slow me down. I returned it and got the X31 pro, w a still larger than avg battery and superior protection. The cameras are great, night vision AND night mode (first uses IR light to see in pitch black, second uses longer exposure time to maximize available light), slow mo, time lapse, panorama, 64MP main is sharp, 2MB macro is nice too. Camera only goes to 4x digital zoom but don't get discouraged, all digital zoom is is cropping. I don't ever go past 3 or 4x anyhow (if you want 8X, edit the photo, zoom in and crop half lol). Lots of features like assignable special side button (push to talk, spotlight, background rec) FM radio (no HPs needed) Phone is running 16GB RAM (8 actual & 8 virtual) and is super fast. 256 GB on board exp to 2TB should be nice too. Lots of included software like phone cleaner, virus protection, AI call recorder and transcriber, AI text editor all work smoothly. Make sure to get the deal where a case w carobeaner & clip included w phone. Very satisfied customer UleFone.

Great phone in its price class
the phone is reliable communication device. The fluorescent orange band really ides in finding your phone amongst the clutter we all have. Large memory and large battery completes the package. I give tis phone my highest rcommendation in this price class.

Bluetooth is sketchy. Lack of options in developer controls.
Very disappointed in this phone. My previous phone was a ulefone armor 9 and it served me very well with very few glitches, so, I was excited to receive this new x31. After a month of use I can say that the call sound quality is not very good, every one on the other end of my calls say that I sound very muffled. It has severe latency when streaming videos and listening to the audio on a Bluetooth device and I have tried it with some very "high end" devices. I have several apps that stream audio with the screen darkened, but when I try it with this unit, it will play about 5 minutes and then stop streaming. I won't rule out another ulefone device because of how well the armor 9 performed, but, beware of the super inexpensive devices that they offer.
