OPPO Reno4 Z Review – This Dimensity equipped phone allows OPPO to compete with pricing vs Xiaomi and Realme (+ it is super cheap on contract)


OPPO have a lot of amazing phones, I have always found they excel at the upper end of the market, in particular, the Find X2 Pro is probably the only £1k+ phone I would have been tempted to buy myself this year.

For their mid-range phones, they have always suffered a little in perceived value for money compared to the likes of Xiaomi and Realme.

Priced at £330 the OPPO Reno4 Z is far more competitive and makes a compelling choice for an affordable mid-range device.

Design and Display

Face on; you wouldn’t be able to tell the difference between this and the Realme X50. They have almost identical dimensions and use literally the same display.

The OPPO is a smidgin thinner, and you can feel it too, it’s back is perfectly flat with no bevels on the edges, unlike other brands. I quite like the way it feels in my hand.

The rear camera arrangement is a square with the two main sensors raised higher than the others giving a line crossing over it. It is marginally more aesthetic than others, and the bump doesn’t bulge out excessively like some Xiaomi phones.

With it being an IPS display the fingerprint scanner is on the power button, it performs exactly the same as every other phone that has adopted this recently.

The display itself is good, with a screen brightness of 480nits it offers around the same brightness as similarly priced phones. On a bright summer day, you may have visibility issues, with it being November in the north of the UK, I have had no such issues so far. The 120Hz refresh rate is well established as being far superior to 60Hz now; it gives you the perception of using a much faster phone; everything is ultra-responsive with no jumpiness in the UI.

Interestingly this does have a 3.5mm headphone jack, while the X50 does not, at this price point I don’t think it is unreasonably to think users would prefer to have this jack available.

There does not appear to be any IP rating, but this is standard for mid-range phones.


The camera specification is your generic mid-range set up of:

  • 48 MP, f/1.7, 26mm (wide), 1/2.0″, 0.8µm, Sony IMX 586
  • 8 MP, f/2.2, 119˚ (ultrawide), 1/4.0″, 1.12µm
  • 2 MP, f/2.4, (b&w)
  • 2 MP, f/2.4, (depth)

On the front you get

  • 16 MP, f/2.0, 26mm (wide), 1/3.06″, 1.0µm
  • 2 MP, f/2.4, (depth)

While this may get advertised as a quad camera, only two of them are usable.

With mid-range phones often having 48MP or 64MP sensors, one of the main differences worth noting is which sensor is used. In this case, it is the Sony IMX 586, which seems to produce superior results than the Samsung equivalent. While it is a good sensor, the 64MP Sony IMX682 is used on the more affordable Realme 7 Pro and Poco X3.

While I am no camera expert, it does appear to offer some improved performance over the cheaper Poco with its higher resolution camera. Taking a photo of a fallen leaf either in normal mode or portrait mode offers a more realistic shot with a natural-looking bokeh. Most importantly the leaf itself has no blurring on it, unlike the Poco which offers an aggressive bokeh that creeps into the edges of the subject itself.

Night mode is generally good, there is no optical image stabilisation, so it is prone to blurriness, but with a steady hand this appears to again outperform similarly specced buy cheaper phones from Realme, even though the camera software appears to be essentially the same.

The camera can only shoot up to s 4K and 1080p video at up to 30fps. Slow-motion is limited to 1080P or 720P. If you are not using a gimbal, you will need to enable the ultra steady mode which offers improved digital stabilisation. One difference between COlourOS and Realme UI is that Realme have the Ultra Steady Max option and they generally offer 1080p/60fps recording too.

Overall, the camera is good for the price point.
