Doogee F1 Turbo Mini has a 4.5-inch IPS OGS display with good viewing angles. It’s just with qHD resolution (960 x 540 pixels), but it leads to 244 ppi, which is not so bad. However there’s one bad thing, which we noticed before with our previous Doogee phone we tested – Doogee Leo. Doogee F1 suffers from the same screen ‘burns’ that we noticed with Doogee Leo. We thought that it’s a defective unit, but it seems that it’s probably related to poor quality components since the problem still persists with other models. Let us explain you what the issue is. If you keep the phone with at least medium brightness for a few seconds on any menu and then switch to another one (open app, slide left/right, just change the displayed screen), you will still be able to see the image/icons of the first menu. They are like burned on the display and look like pale watermarks. After certain time they will disappear, but we can’t consider this as normal behavior. You can check the pictures we made and also the video review at the end to get a better idea of what exactly these burns on Doogee F1 are.
As we said the display is an IPS one and has good viewing angles. However in some cases, certain angles changes affect the color reproduction, so it’s now always 100% perfect. The colors itself doesn’t look absolutely accurate. Actually they are a little bit darker, than it should be. This can be easy noticed, when you are in the Settings menu. The low resolution is not an issue, but you can still notice that the icons are little bit blurred and the details and are not absolutely clear.
The screen is covered by Dragontrail glass and it’s scratch resistant (however no official info about what’s the exact level of protection on Doogee F1).
As you can expect the 64-bit MTK6732 performs smooth. There’s no lag and switching between the applications is just flawless. We ran Antutu, Geekbench 3, Vellamo, Quadrant, GFXBench, Browsermark and Kraken 1.1 tests. Some of the results are pretty good, but others are a little bit disappointing. We expected more from the single and multi-core results. They are still good and even better compared to other more expensive devices (like Galaxy S4 for example). Probably the results will be much better, when the phone gets upgraded to Android 5.0 (as promised by Doogee), because the new operating system can use all power of the 64-bit processor. Check the screenshots below.
The overall performance is really good and absolutely lag free. Playing games is not an issue, because of the mighty ARM Mali-T760. It’s the same GPU, which can be found in Galaxy Note 4. Our tests showed that Doogee F1 gets better graphics results compared to Galaxy Note 4 (equipped with the same GPU), Nexus 5, Sony Xperia Z1, Galaxy Note 3 and so on. Of course the good results are thankfully to the low resolution as well. Remember, the phone has just qHD resolution.
