GOOD THINGS
> Light compact phone, beautifully designed, classy and cool. Easy to handle even if you have small hands.
> The charging speed is amazing. Charger is really good quality. This is, perhaps, one of the main reasons I love this brand.
> Battery capacity is also amazing. I have experienced that for years with my old Oppo and still experiencing it now with this new one.
> Fast responsive intuitive touch.
> Clear, crisp vibrant images.
> Camera is very clear and detailed. There are many adorable stickers for selfies, a decent number of effects, basic adjustments, different light settings and an expert mode to take photos with manual settings. The results are excellent from both front and rear cameras.
> I thought that face recognition capability would be an unnecessary thing, but now that I've experienced the joy of unlocking my phone and apps by looking lovingly at my device, what the heck?! I think this is a must. Fingerprint, as in previous models, is really accurate and another way to lock/unlock phone and apps.
> I love the square 'button' on the screen, which is like the one tablets have to allow easy switch between open applications/windows. I really missed that in my previous phone, and I'm happy to have it in this one.
> The toggle is easily customizable and has a good deal of functions to choose from.
> Multi-screen allowed.
> The sound, which was one of my main complaints about my old Oppo has dramatically improved. The quality of the recording has improved dramatically, so much so that a friend commented on it.
> There is a safe kids' space for you to allow your kids to use the phone in a censored way, as you can put your naughty photos, videos or stuff in an inbuilt safe that they cannot access.
> There are tons of security features in this phone to protect your privacy, the leaking of the information from your apps, phishing and what's not. The phone comes with a simple but handy phone manager (to optimize your phone, which includes a simple anti-virus, and special settings to protect payment applications). One of the things I like the most, is that, regardless of which keyboard you are using, when you have to login and type a password the system automatically switches to the inbuilt keyboard, so your passwords cannot be 'recorded'. Also, you don't need any extra app to lock your applications as you can do that from your phone settings.
> Some apps are part of the system: compass, torch, night shield, calculator, assistive ball and even Google assistant. I personally don't want to be assisted by Google, but if this is your cup of tea, you can easily activate it and use it from your phone.
> One of the pages of the phone screen contains a customisable Google shortcuts area, a Google search area, a steps tracker, and a few other things that you can add if you don't activate Google Assistant in that space
> Free wallpapers and themes in their 'theme store' app.
> Unless you really want a new case , the included translucent silicone case will do the job and be enough to protect your beautifully-colored device. It is a bit rigid, but it adjusts perfectly and is not 'slippery' when I put it on my lap.
ANNOYING THINGS
> The most annoying thing to me is the way the designers have reorganized the phone settings area. I really appreciate many of the additions and improvements, but I would had rather kept the previous settings structure (very similar to pure Android) and add new sub-sections, than doing what they've done. It took me a while to go through the settings area to customize my new Oppo. Any person changing from any pure Android to Oppo's derivative Coloros system might be baffled.
> Lack of a purposely-built app drawer. I've downloaded an app that does just that, but it's difficult to understand why the designers have ignored Oppo customers' complaints on this issue for years.
> This is not a true dual SIM phone, but a hybrid dual SIM, i.e., you can use 2 SIM cards or 1 SIM card and 1 memory SD card, not 2 SIM cards and 1 SD card. Why not, Mr Oppo?!
> The download folder is nowhere to be seen. It was part of the system in my previous Oppo, not in this one. I use that folder a lot. I had to install an app to access that folder easily. What were the designers thinking?!
> Although the quality of the sound is good, the speaker has some some sort of glitch and if I am hearing a voice message and move the phone, the sound stops.
> The sound volume has been reduced, which is OK, if you use earphones to listen to anything. However, if you want to use the speaker, the volume is not high enough to be heard in a normal-noise environment, not to say in a noise environment. My old Oppo was way better in that regard.> The tips guide is too short and incomplete to be a proper user guide.
> No inbuilt notepad or notebook.
> The inbuilt steps tracker is not customizable and it has a life of its own. I mean, it cannot be stopped or switched on at volition.
> The toggle was great before regarding contrast. There has been an update of the system since I bought this phone, and now the toggle is white and green, very bad for people with sight problems or simply poor sight. I was thinking it could be customised to turn it into the previous dark theme, but it is not possible.
> I chose this purple-ish model because it looked truly beautiful in the shop under artificial lighting. In normal light and with the transparent cover on, the color is not so noticeable and not so beautiful, and it looks almost black. Waw waw waw. If I had known, I would have chosen the red model.
> The colours aren't as vibrant or beautiful as those of my previous Oppo, especially for interior.
USE TIPS
> To change the background and theme, go to the theme store in-built app. Backgrounds and themes are free; download them and then apply them in full or just to the home wallpaper, lockup screen wallpaper, or just the icons.
> To access widgets and screen effects, pinch in on the screen's empty space.
> To take a screenshot, simultaneously press Up volume button + power button. Also, if you enable the function in the phone settings, you can use sliding of three fingers down to automatically capture the image.
> If you optimize your battery, vibration, sound, notifications, brightness, and data settings, you will have battery for nearly two full days. Do you really want your phone to send you endless notifications about anything? Do you want all your notifications to have sound and vibration? Do you want your phone to vibrate for everything? Do you want the keyboard to have typing sound? Do you want full brightness all day? Do you need to have your WiFi/data on all day long? The answer will change from person to person, of course, but generally speaking unnecessary sounds, display features and notifications drain the battery of this phone unnecessarily.
IN SHORT
I really love this phone. I think it is a bit tricky to get around the settings during the first two or three days. However, this is a de-luxe-feel, good quality, sturdy, classy and wow device at cheaper prices than other smartphones with similar or identical features. Not cheap though.However, the designers of interface and hardware features seem to be out of touch with the needs of customers, even those loyal Oppo customers like me, as some things are altered and made less user-friendly than before, some general complaints about the system cried out by users are ignored, the result of that is the section annoying things, which is a bit long for any phone or brand that costs as much as this smartphone.
