The quad-core Mali G51 of the Honor 8X and Adreno 509 of the Nokia 7.1 are roughly twice as powerful. Even the ageing Adreno 506 of the Snapdragon 625 system on chip used in the Moto One is roughly 20 per cent more powerful. If there’s a weak point to the Galaxy A7, it’s this graphics chipset. And that it’s paired with a rather good CPU side is all the more annoying.
But how does this pan out in real-world use? It depends entirely on how much of a gamer you are. Most popular games are made with less powerful phones than the Galaxy A7 in mind. However, a game that gives you more control over graphics settings highlights its limitations. Ark: Survival Evolved only runs at “low” graphics, and only does so well if you significantly reduce the smart resolution slider, which renders part of the scene at lower fidelity.

This kind of compromise traditionally applied to every phone at this level. Mid-range chipsets of the last few years tended to perform well in raw CPU benchmarks, but always had much less powerful graphics chipsets than their top-end relatives. Honor changed that this year with the frankly alarming Honor Play. It has a twelve-core Mali G72, to the A7’s older dual-core Mali G71. This is a huge disparity.
And while the Honor Play has been delisted from 3DMark for cheating, the difference in benchmark scores is not solely down to that. The Honor Play scores around 3000 points in Slingshot Extreme. The Galaxy A7 manages just 740. In every other respect the Galaxy A7 has what a great gaming phone needs. The screen and storage are there, but its raw graphics power is the weakest around.

Hardcore gamers should think twice. Samsung Galaxy A7 — Camera There’s some of the same effect in the camera: class-leading specs on paper, but the results are not quite on the same level. The Galaxy A7 has three cameras on the back. There’s a 24-megapixel main sensor, an 8-megapixel wide and a third sensor for depth, to enable Samsung’s “live focus” background blur images. If we forget image quality for a moment, this is an excellent setup for compositional flexibility.
You can take extra-wide shots, DSLR-style shallow depth of field images, and while there’s no “optical” zoom, digital zoom is there as a handy, if deeply unreliable, friend. On the surface daylight photos are also very pleasant. Samsung’s processing gives images a warm, colour-rich look, with noticeable raising of mid-tones to improve dynamic range. Check out the pics below.
Pretty nice, right? However, compare photos with the Nokia 7.1’s 12-megapixel images and the benefit of the 24 megapixel count here is clearly next to nil. The main camera takes surprisingly soft photos. There’s more detail than in the 8-megapixel wides, but fine detail is still markedly worse than that of the Honor 8X or Nokia 7.1. That the sharpness of the 8 and 24 megapixel images is comparable, even though the main camera has a much better f/1.7 lens, is damning. Night photos are only passable too. A wide camera gives you a more dramtic view than a zoom Some images may look soft close up, but the processing makes for pretty photos Night shots are only passable The Galaxy A7’s main camera is lower-end than it seems on paper, and it’s likely because of the sensor’s properties.
A Sony IMX576 sensor chip is used in the rear camera. It has 0.9 micron sensor pixels. 1 micron sensor pixels are small.
These are tiny. The front camera uses a 24-megapixel IMX576 too. In this context it actually seems quite good. Huawei’s superb Mate 20 Pro uses the same selfie sensor. Strangely, Samsung lists the Exynos 7885 Octa processor’s maximum camera resolution as 21.7 megapixels. Could this be to blame for what is, in some contexts, surprising image softness?
Who knows. Video capture is capped at 1080p too, which may surprise when the resolution is so high. This is not a camera disaster zone.
