The resale values that you site are not accurate. I sold a 6 month old OP5 on Ebay that was still under warranty and came with over $100 in accessories. For two months the phone kept selling over and over to fake buyers that never paid for the phone or responded to messages. When I listed the phone as an auction the top 2 bidders would always be fake which drove up the apparent sale price. All of those transactions showed up in the searches on Ebay even though I was never actually paid for the phone. When I actually sold the phone to somebody who paid for it the price was less than half what the fake transactions suggested the phone was worth and less than 30% of what I paid for the phone and accessories.

The OP3, OP5 and OP6 are virtually impossible to sell used because nobody wants them and the actual resale value is less than half what the 3T, 5T & 6T go for even though the two variants were released within 6 months of each other and cost roughly the same at launch. The OP6 is going to be even harder to sell used than the OP5 was because people actually waited for the 6T this time instead of wasting their money on the OP6. Sites like Gear Best started offering the OP6 at a 30% discount 3 months after launch because of poor sales which was a first for One Plus phones.

All you need to do to receive immediate notifications from any app you want in EMUI is remove the app from automatic power management in the settings which is a simple process that takes a few seconds. You can also remove every app from automatic power management at once if EMUI power management is too aggressive for your taste.

Oxygen delivers a poor user experience because of its inept coding. If you go on the official One Plus community site you will see hundreds of posts from owners complaining about excessive battery drain and overheating--and the number of posts always spikes after an OTA is released.

One Plus phones are snappy thanks to the hardware but because of the poor coding (not only in Oxygen but also in the device firmware) they are far from smooth. If you scroll slowly in many apps there will be noticable jutter caused by frame drops. This was a problem on the OP5, 5T and OP6. A $200 Redmi phone delivers a smoother UI than a One Plus phone.

An MI A1 or MI A2 runs genuine stock Android rather than the faux stock One Plus offers, delivers a smoother UI despite having less powerful hardware, takes much better pictures and costs less than a third of what a One Plus phone costs. The MI A1 and MI A2 also have significantly better resale value. When I sold my MI A1 used it fetched 90% of its original cost. When I sold my Mix 2 used it also retained a 90% resale value. Even my Essential PH1 retained a 70% resale value. My OP5 retained less than a 30% resale value over the same period of time.

One Plus has been caught multiple times putting spyware in Oxygen. They have been caught multiple times posting fake member comments on social media and tech sites. They allowed customer credit card data to be stolen from people who made purchases on the One Plus web site for more than two months after they were first notified of the problem. They solicit positive reviews in exchange for free phones and then get them published in various places as if they were professional unbiased reviews without acknowledging that the reviews were actually provided by One Plus.

The difference in build quality between an OP6 and a Huawei flagship is massive. One Plus delivers flagship specs in phones that barely have $200 build quality. It would be the equivalent of Xiaomi putting a top of the line CPU in a $200 Redmi and dubbing it a "flagship killer"--but the Xiaomi version would have competent software coding and take much better pictures.
