Overall, I'm happy with the phone, but bearing in mind that I’m upgrading from a 5 year-old phone... (Samsung A3 2016), and it costs nearly twice as much, you'd expect massive improvements in every area, it is disappointing in a number areas (I originally gave it 3 stars but after living with it for a year, I'm upping it to 4 stars, because basically I like this phone. Also, it's come down in price considerably since I bought mine.) See my comments below for the details of the pros and cons from my personal perspective.I Like:- Glass-backed not plastic (but only on the silver version)- Dual Sim- Super-fast 65w charging.- Eye-comfort option on the screen.- It’s a good size without being excessively large- Fingerprint and face recognition very fast and effective.- Factory fitted screen protector- 3.5 mm jack- Wide angle lens for camera.- Front camera hole is very discrete.- Nice look and feel.- Fast overall performance.- The 64 megapixel camera is defaulted to a lesser resolution (to keep photo size down)- I feel it’s a nice looking phone with a nice feel, and the silver finish looks almost like polished metal in some light conditions.- Oppo Customer Support has been responsive when needed.I Don’t Like:- In the normal mode the home screen has no 'Apps' Folder so everything just appears automatically, if there are pre-installed Apps you don't want to see your home screen pages, you must copy them to the 'tools' folder.- the volume settings erratically turn themselves right down sometimes which leads to missed calls.- frame/bezel looks like metal but is in fact plastic I think.- Loud speaker sound quality seems less good compared to my old Samsung A3.- Flashlight is considerably dimmer than on my old Samsung.- Android Auto is pre-installed but apparently there is no way to launch it. However I raised this with Oppo who informed me that you can download 'Android Auto for phone Screens' thin in-built install I guess only works if you have a very recent car.- User interface on Settings, Widgets, etc. looks and feels rather low-end, it’s better on my 5 year old Samsung A3 2016 and generally there is not much configurability, basic settings seem difficult to locate.- 3.5 mm jack is on the left-hand side at the bottom of the phone, thus interfering with typical desktop phone stands, would be ideal to right next to the charging port.- The coating on the glass back makes it feel like plastic. The coating also reflects various colours in certain lights (maybe some people would like this) I would have have preferred a straightforward shiny metallic look. Overall the phone feels quite nice in your hand. A high-end look and feel is v. important to me personally and I absolutely reject plastic constructed phones, which is quite limiting these days.- Icons on notifications bar, and pull-down notifications are excessively tiny, making it difficult to see them, or to hit them easily, this seems not configurable. (Android 12 recently rolled out has improved this somewhat)- Icons generally have no choice or configurability unless you sign up for a 3rd party app.- The front camera hole, positioned at left side, whilst discrete, gives a misalignment which makes close up selfie taking a little awkward, and also easy to partially obscure the camera with your thumb.- Poor use of screen space – widgets and icons don’t use of about 5 mm of space at each side of the screen– given that having a larger phone is already irksome, you’d think that manufacturers would optimise screen space usage as an absolute priority...- Minimal water proofing ip52 I believe (by now I’d expect to see this feature at this price)- No contactless charging.- No SD card slot, but 128 Gb should be plenty I guess.- SAR emissions seem to be on the high side.- Standard SMS app seems very minimalistic, not a nice look and feel. Same for most of the inbuilt apps.- I took an indoor photo in artificial light with the wide-angle lens and the result is very grainy.- Comparing an indoor artificial light photo between my Samsung A3 2016, and the Oppo, there is little discernible difference in quality, expect perhaps Oppo image is somewhat brighter.- Can't find any options for voice commands on the Camera.As I say, quality look & feel is very important to me, and given that most phones are technically competent these days – it becomes a key differentiating factor – see how Apple have finally got it right with the iPhone 12. I would probably have bought a mid-range Samsung if they offered glass construction but they don't anymore. Or, at my price point, an LG Velvet (though a bit on the large side) - which seemed to have everything I would want - but LG are closing down their mobile phone business.Hopefully, Oppo or someone else will step up to the space vacated LG, by providing a mid-range phone that gives quality look and feel + all the important features at an affordable price.
