Ulefone Metal XDA Review: An Often-Hilarious Trainwreck of a Phone, But a Step Forward For Ulefone’s Developer Relations
The Ulefone Metal is an entry level smartphone with a premium finish, that just can’t quite stick the landing. It comes incredibly close to being a phone with good price-performance (especially thanks to Ulefone releasing the kernel sources and trying to support developers), but some issues with polish and a couple “What were they thinking?”-style design decisions create a questionable user experience (for now).
In this review, we’ll take an in-depth dive into the Ulefone Metal. Rather than listing specs and talking about how the experience felt, this feature attempts to provide a thorough look with contents relevant to our reader base. At XDA, our reviews are not meant to tell a user whether a phone is worth buying or not — instead, we try to lend you the phone through our words and help you come to the decision by yourself.

The feel in-hand reminds me of my old HTC Legend. It’s got that same “heavier than it looks” feel to it and relatively-sturdy looking construction. Its body doesn’t feel “premium” like an HTC 10, but it feels nice in the hand in it’s own right. The solid metal construction and chamfered edges come together nicely. The only problem with the frame itself is that it is not properly supported at the MicroUSB port, allowing you to easily bend the thinner metal between the MicroUSB port and the display into the device with just a small amount of pressure.
The feeling in-hand doesn’t extend beyond the frame however. The buttons aren’t loose, but they feel squishy and are quite silent. There’s no satisfying tactile feedback, there’s no click, it just sort of moves out of the way. The SIM tray is a similar story. Yes, it works, but it doesn’t quite click into place the right way, and it can be a tad bit hard to open at times. It often catches on the way in, and you’re left unsure as to whether to push harder (for fear of breaking it), or to take it out and try again. The MicroUSB port is again the same story, and you feel like you’re almost going to break it.
Speaking of buttons, the capacitive buttons show some… interesting… choices as well. Not only is the back button on the right (which to be fair, despite what Google recommends, is preferred by some), but the multi-tasking button is instead bound as a menu button, and a long press of home is how you access multi-tasking. I couldn’t find a way to rebind them either. Oh, and they’re a mix of Holo and Holographic style buttons too (except with a blockier back button, and a chimney on the home button).
Interestingly enough, the buttons in the manual don’t match the buttons on the device. In the manual they instead show the home, menu, and back buttons that appeared on the Samsung Galaxy S II, and don’t list how to access the recent apps list.
The Ulefone Metal also shipped with some complimentary accessories, which is nice. Unfortunately the accessories themselves are not so nice.
The case is advertized as being leather, but doesn’t feel like it… that’s fine though, leather isn’t needed for this. It’s a windowless flip cover which fits the phone pretty well, and it wakes the phone when you open it. Unfortunately it doesn’t shut the phone off when you close it. Instead, it puts the phone into a media control mode (which you can’t use through the cover, although it appears that the cover for Ulefone Future can use it) and waits for the screen to timeout before shutting down (which could be a while depending on your settings).
The device also shipped with a tempered glass screen protector, which is a great addition, as it can be hard to find good screen protectors for some smaller brands. Oddly enough, my device came with two screen protectors pre-applied, the usual shipping one with information about the phone on it, and a second one beneath that which felt like a standard plastic screen protector. I’m not sure if it was meant to be a permanent addition, however it definitely wasn’t applied properly, so I was thankful for being able to switch it out.
The tempered glass screen protector is supposedly curved to fit the 2.5D edge of the screen (although, upon inspection, the edges look rather flat), and supposedly blocks blue light to “protect your eyes” (completely missing the point behind blue light filters). Rather than mentioning the effects of blue light on our circadian rhythm and sleep cycle, Ulefone’s advertising claims that blue light is “a kind of high-energy light that can increase the toxin in macular region of human eye balls” and that “such a protective glass is indispensable to mobile phones.” (nevermind that if that was actually an issue, they could just tune the display to reduce the amount of blue light generated, either through hardware or software).
Ignoring the toxins bit (what “toxins” exactly?), it’s a bit concerning that Ulefone either seems to think that non-ionizing radiation (more specifically, visible light) is dangerous at the levels created by a phone, or they are playing to that crowd in an attempt to sell more devices. Worse still, their marketing implies that they actually went and made their product worse (by including a screen protector that is designed to reduce colour accuracy instead of a normal one) in their half-hearted attempts to attract that crowd. Thankfully, despite what their marketing claims, the screen protector appears to be just a normal screen protector anyway, and won’t damage colour accuracy.
Software – UI
The UI is nice and clean with an approach that stays relatively close to stock Android. The quick settings menu is almost unchanged, with the only major differences being a change in logo for the cellular data symbol and the addition of a toggle which launches a pop-up for audio profiles (separate from the do not disturb toggle).
The settings menu saw a more drastic change however. In place of Android’s settings list (with toggles), there is a four-by-eight array of icons which are sorted into categories (“Wireless & networks”, “Device”, “Personal”, and “System”). These icons are bright colours that feel a bit out of place next to the the rest of the UI, especially when compared to the relatively muted camera and settings icons that Ulefone used. The bright colours don’t carry further into the settings menu however, as once you pick an icon, the page it links to is usually largely the same as it is on stock Android, with the notable exception of the prominently placed “Turbo download” menu, which allows you to use Multipath TCP to simultaneously download over WiFi and cellular connection.
Ulefone also has a persistent notification giving you a quick link to the app permission management page. The only way to get rid of it is to disable permission management (which Ulefone makes nice and easy to do for some reason), and even then it comes back every once in awhile (like when you reboot).
The default launcher comes with two pages dedicated specifically to music and photos, with a giant record player on one (with no visible playback controls), and a small photo gallery on the other (which only lets you see up to two photos at a time, and both are rather shrunken at that with a substantial amount of wasted space). Thankfully both pages can be removed in the settings menu.
The camera UI is relatively basic, but really doesn’t fit in with Material Design. The menus and shutter button in the camera have a distinctive Gingerbread feel to them, with certain parts taking on a bit more of a transparent Holo-esque design.
The sound recorder similarly feels out of place. The flat title bar simply doesn’t fit with the gradient on the timer, or with the slightly skeuomorphic VU meter for that matter. The UI just feels like a mishmash of different styles. It doesn’t have an identity.
While it was clear from day one that the Metal wasn’t licensed by Google (as it was missing almost every required pre-installed app, except the Play Store, Search, and Gmail), Ulefone solidified that position in the first software update I received from them, where they lifted the icons from multiple Google apps for use in their ROM, including the logos from Google Play Music, Google Photos, and Google Messenger (the latter of which they modified by turning some of the lines from white to transparent, removing the depth that the icon normally has). That may fly under the radar while Ulefone is a small company, but doing things like that now leaves them open to copyright lawsuits later on if they grow. Yes, the logos fit well with the majority of the UI (and certainly fit better than the old Gingerbread-style stock Gallery app that Google has abandoned), but there are other options that also would fit, and without being copyright infringement at that.
“The UI just feels like a mishmash of different styles. It doesn’t have an identity.”
“The UI just feels like a mishmash of different styles. It doesn’t have an identity.”
That being said, the logos that they designed themselves are actually not half bad (I’m assuming that they were designed in house). The camera icon follows Material design fairly well, and fits with the rest of the UI. It really is a shame that Ulefone felt that copyright infringement was a better path than continuing to create their own logos.
Software – Features & UX
There is a floating shortcut button, reminiscent of Facebook’s Chat Heads and Paranoid Android’s Halo, that gives you quick access to some useful features, like a clipping tool for screenshots, or a floating calculator, or quick access to settings. I’ll be the first to say that I can be extremely picky about how this type of UI element is implemented (I absolutely adored Halo, but Chat Heads never really caught my attention), and something about this method just doesn’t sit right with me. It might have been the inability to hide it (even when watching video), or how slow the animation to bring it up is, I’m not quite sure, but whatever it was, I promptly started looking for a way to disable it, and I couldn’t find an option. I understand the appeal of a floating quick actions tile, but I never really found any benefit in this one, and it only ended up getting in the way for me.
I normally take a few tries to get my phones to learn my fingerprint, and the Ulefone Metal is no exception there. What was an exception was that the Ulefone Metal has the ability to bind the fingerprint sensor to open different apps for different fingers. This can be a very useful feature, but in this case it brought a major issue. Ulefone didn’t properly set up the bounding boxes in the fingerprint menu, making it extremely difficult to access the menu for renaming and deleting a finger. The settings gear to access it is very small and hard to hit with my big clumsy hands, with most of my attempts to access it resulting in me opening the menu for choosing which app to activate with that finger instead. It got to the point where I just gave up, and left the phone without a working fingerprint sensor, which is really a shame. Thankfully, it is an issue that could be relatively easily fixed with a software update. HTC, Sony, Xiaomi, ZTE, etc. all have a way of handling this without issue. You just make the bounding box be a square from the top of the row to the bottom of the row (and the same width), instead of just barely covering the target object itself. You can even place a small visible separator to help people identify where the button ends and the rest of the row begins. It’s a tiny little thing, but it can make a world of a difference.
While the device does let you hot swap SIM cards, it can be a bit slow to recognize the change, resulting in a bit of a wait after you put a SIM card in before you can use it, or a bit of a wait after you take the SIM card out before the data connection stops.
The Ulefone Metal also has a weird design choice in that any time you come within range of an open Wi-Fi network, it notifies you. If your phone is set to vibrate, it vibrates. If your phone is set to ring, it rings. As with most features that Ulefone added, there doesn’t seem to be a way to turn this one off. The only way I found to disable this “feature” is to disable the Wi-Fi network notification completely, which results in you losing some functionality in order to disable Ulefone’s “addition”, just like with the permission management notification.
While phone SoCs have come a long way, there is still a substantial performance gap between a flagship SoC like the Snapdragon 820 or Exynos 8890, and an entry level chip like the MediaTek MT6753. The eight A53 cores running at 1.3 GHz are distinctively low-end, and the three cluster Mali-T720 GPU isn’t a powerhouse either. The experience is designed with the intent of competing with Qualcomm Snapdragon 4xx and 61x series chips, and it shows. While the MediaTek MT6753 won’t win any performance titles, the A53-based design should have fantastic energy efficiency, at least in theory.
CPU & System
While the A53 isn’t very powerful, it does take up a tiny amount of die space and is incredibly efficient, allowing MediaTek to shove eight of them into the entry level MT6753 chipset. As a result, the Ulefone Metal suffers heavily in single core tests, but the eight A53 cores allow it to perform reasonably in multi core tests.
This shows up very clearly in Geekbench, where the phone is barely able to hit 600 in single core testing, but multi-core testing from idle sees it hitting a respectable score of 2468, about half of what the flagship chips are putting up currently.
The Ulefone Metal has a weak showing in PCMark however, with competing devices like the Honor 5X, Nextbit Robin (both of which we reviewed earlier), and the ZTE ZMax Pro handily beating it in every category except for the Web subscore, where the Ulefone Metal pulled even.
AnTuTu tells the same tale of woe, with the similarly-priced ZTE ZMax Pro leading in every category (and doubling the score for 3D). Some of the subscores for AnTuTu stay relatively close though, with the Ulefone Metal not trailing by too much in the RAM subcategory.
After seeing the results of the other benchmarks, Basemark held no major surprises either. While the Ulefone Metal pulled even with the ZTE ZMax Pro in the System subscore, it fell behind in every other subscore, with only half the graphics score of the ZTE.
In our sustained load test, the Ulefone Metal gets incredibly hot, with my Seek Compact Pro reading the surface as hitting a scorching 52°C | 125.6°F, and still climbing by the end of our test. Surprisingly, single core performance did not drop despite those high temperatures, but multicore saw a ~10% drop in Geekbench score from the first run to the last. This test barely fazes most devices that we review, and this result shows substantially higher temperatures than even the Snapdragon 810 devices that were known for throttling as a result of overheating. It should be noted that while the Ulefone Metal hits 38°C | 100.4°F after just one run (more than most phones’ peak temperatures in this test), the device started at just 26 degrees in our pre-test measurements.
This phone doesn’t throttle much, but it really should. There is no excuse for a phone getting so hot that you can barely hold it. Even temperatures in the high 30s, which the Ulefone Metal hits after just a couple minutes of use, can a be a bit uncomfortable. Something in the 50s is outright hot to the touch.
GPU & Gaming
The phone’s GPU is incredibly weak: a three-cluster Mali-T720 simply doesn’t keep up with any Qualcomm chip currently on the market, and it really shows. The Ulefone Metal’s low resolution helps to mitigate the issues that the weak GPU brings, but even that can only do so much.
3DMark Slingshot is barely even a slideshow (with certain sections being listed as having a frame rate of “0”), Manhattan has single digit frame rates, and even the age old T-Rex brings the Ulefone Metal to its knees.
Thankfully, despite getting quite hot in our sustained graphics test, frame rates didn’t drop further with continued usage. Although it was already pretty close to 0 anyway. In our 3DMark throttling test, the Ulefone Metal hits 43 degrees after just its first run, which also happens to be the temperature that the Google Pixel XL peaked at in this test, and it continues to climb as the test goes on. Towards the end of the test, performance drops a little bit, but you really should expect more throttling from a device that is getting this hot (and continuing to get hotter as the test ended).
GFXBench’s battery life test is a similar story, with performance staying mostly around the same level, while temperatures continued to climb. The results were surprisingly consistent as the test went on, with the results all staying in a range of 395.1 frames per run, +/- 1.1 frames. That’s a mere 0.3% variance up or down, resulting in substantial range compression (and a spiky looking graph). For comparison, the Pixel XL sees a drop of around 10% from its first run to its lowest score.
With how tiny the performance drops are for the Ulefone Metal and how extremely high the temperatures get (in both our CPU and GPU throttling tests, as well as in endurance tests like PCMark’s and GFXBench’s battery life tests), it almost looks as if the Ulefone Metal simply doesn’t have any substantial thermal management code (performing at the highest level it can, regardless as to how hot it gets), which would be scary if true.
Memory & Storage
Having 3GB of RAM is absolutely fantastic for an entry-level phone, and should be more than enough to ensure that you won’t run out of RAM in all but the most RAM intensive situations. This is helped further by the fairly lean OS that the phone runs by default. With nothing open, the Ulefone Metal was reporting just 850MB used, and over 2 GB available.
|Read Speed||154.10 MB/s||11.87 MB/s|
|Write Speed||37.66 MB/s||4.63 MB/s|
The storage is about on par with what would be expected for the price (tested on Androbench, threads set to 1 and sequential buffer size set at 256 kB). While 16GB with an SD card is enough to get by on (although I tend to prefer 32GB and higher), and while the performance is definitely on the slower side, it is acceptable for the price.
Real World Performance
The OS generally performs fairly smoothly, but there are a couple weird hangs in certain places. When you go to unlock the device, after swiping up it will freeze for a half second before bringing up the page to enter your pattern/pin/password.
Some of the bugs are just strange. In the default launcher, when you long press an app icon to move it, usually it will stay on the page it is currently on, but occasionally it will jump to the primary home screen (even if that screen is full).
Setting up the cellular data connection for the first time is a bit of a pain. The phone defaults to data being turned off (which is a good idea to some extent), but after inserting a SIM card it asks you if you wish to enable data for that SIM card. If you hit yes it turns on data for the SIM card in Settings->SIM cards, but it leaves the one in Settings->Data usage->Carrier Name set to off, and you have to manually go in and change it.
