[OnePlus 8 Pro Questions & Answers] Truant_Luce:
Previous HTC rooter here. Had the 10, then the 12+

This phone is slightly more root friendly. And no, there is no custom bootloader. You will not need to go and get a token from a website to unlock the bootloader. As far I can tell at a glance, S-OFF isn't a thing.

If you set up magisk properly, google pay will work (for now). I use it every other day. Widevine certification will default to L3, so you can't root and keep that in L1 like you could with HTC. I don't get it myself.

Do: backup persist partition (and modem1 and modem2 I guess? Someone recommended it) For sure. While rare, and particularly an issue with magisk canary, if you want any chance of the fingerprint sensor to last, backup the persist partition. Otherwise, you're technically sitting on a ticking time bomb and it can pop at any time and no longer function. Haven't heard anything too recent, but better safe than sorry. Only other solution is RMA.

HTC phones, least the ones I used, used LCD panels. I love LCD, because it seems more protection from burn in and screen retention, and less issues for screen problems. That said, this is a newer screen and amazing, just not as amazing I feel as an LCD screen (although this is a better screen, via tech upgrades and more). Keep in mind there are rampant reports of green tint or burn in right away, black crush, and other screen issues. If you do go with the phone, I recommend giving that a thorough once over.

Customer service is in par to that famous thing of kids going, "Are we there yet? Are we there yet? Are we there yet?" Type stuff. Do not expect anything from customer service outside what directly is stated to contact them (such as RMAs), and then be prepared to fight tooth an nail for it, and prepare for any additives that arise from it. I would have better odds of customer service with comcast (as weird it sounds) than with oneplus' customer service. They will not honor anything outside what you can do on the website yourself.

What I mean by that, is if you have a coupon for a 10 dollars off accessories, and you accidentally "place" an order and forgot something, and want to add it again? Either wait for your current order to expire to then allow for the coupon, or you're SOL. And to add: By far, the oneplus 8 launch was the worst I ever experienced from any industry, especially as it comes to ordering it. So if you stay, keep that in mind.

A lot of people recommend to just forgo the warranty and get your own via other means (my renters insurance provides it for like, 6 bucks a year) as it's literally the same boat as customer service, with reports of people being charged erroneously like, 500 dollars for some incompency from the warehouse.

If you're in the US the global model I believe is the one you want. UK, INDIA, and CHINA have their own model. While it can be possible to use these, keep that in mind that you most likely want the phone to be compatible with the bands of your country. I believe the india / chinese model is the only one who now has the photochrom filter disabled, thus if you do go with one of these, you'll want to either install a magisk rom, or fix it yourself with one of the many guides available.

You can convert the phone to different models more easily. Such as chinese to global, as compared to HTC phones. You don't need to do superCID like you did or similar I believe, and it's very tolerant of that. In fact, the first oneplus phone even shipped with CyanogenMod installed, now more or less known as lineageOS. This device is very customizable friendly. In fact, some roms will even allow you to uninstall practically anything you want.

Speed is the name of the game, and if you like fast devices, this will blow you out of the water most likely. I personally run .5 on all animation speeds myself.

And of course, if there is issues and you really messed stuff up, you can use the MSM tool or whatever it is to correct the issue. (Again, keep that persist backup in case)

The device will detect if you're rooted and installed either the small OTA package, or the full package in case. I used to always have TWRP installed, but I don't even use it anymore myself so much. The full package can flash through the system update too, btw. Only upon unlocking the bootloader will the data partition be wiped that one time.

There is the hole punch camera, and that was a significant selling feature for me for HTC, but... I figured I'd deal with it this once. Keep that in mind if this feature bugs you as it does me.

Ok, this was my tidbit of info. If you need more clarification or something, ask. Otherwise, enjoy.
