UPDATE: As it appears, there’s an issue with OpenGL rendering in Android O on Nexus devices. So, in order to make your device working better, it’s a good idea to switch to set rendering to OpenGL(Skia). This workaround slightly improved my device’s performance, and hopefully, it’ll do the same thing for you.

Here’s how to change GPU renderer on your Nexus 5X:

  1. Go to Settings > System
  2. Go to Developer options, and switch OpenGL Renderer to from OpenGL(Default) to OpenGL(Skia)

Hopefully, Google will fix this in some future updates.

Thanks Georgi for the tip!

Original article:

Some Nexus devices, including my own Nexus 5X, have just received Android Oreo update. People are still confused about the Oreo rollup, as nobody knows for sure when their phone will get the update. But those who already received it, might not be totally happy with the new Android version.

I’ll get straight to the point. After installing Android Oreo, my Nexus 5X started running slow and laggy. Which is the complete opposite of ‘better performance’, promised by Google. Every action on the phone seems to perform slower now.

It even takes a couple of extra seconds for the keyboard to show up?! The revamped notification bar is laggy, it takes longer than usual for the phone to unlock. Apps are slower, and so on and so forth. Of course, the phone hasn’t been rendered unusable, but the fact that it’s slower than it used to be a couple of hours ago (when everything worked seamlessly), is just annoying.So far, I haven’t found any helpful info about this problem online. But that’s probably because the majority of users hasn’t even got the update yet. And I was ‘lucky’ enough to receive it earlier.

Since Android Oreo is probably the last major update for Nexus 5X and Nexus 6P, the only thing that crosses my mind is that Google hasn’t optimized the new system for older phones yet. Which is totally unacceptable!

I’ll keep an eye on the situation in the coming days. Things will probably get clearer once more people receive the Oreo update. Hopefully not too many people will suffer from this issue, because that could be a huge problem for Google.

As soon as I find more info or any solution for this issue, I’m going to update this article accordingly.

Have you already installed Android Oreo on your device? Are there any issues? Let me know in the comments below.
