Fix: OnePlus 5T Face Unlock Slow Down

Did your shiny Oneplus 5T Face Unlock slow down? I still remember how instant I could get to the home screen once I setup my face unlock on my brand new Oneplus 5T a month ago, but few days back I got to notice that there is a delay between when Facial recognition is done and when the phone unlocks.

This wasn’t about the process of Face Recognition, I knew the Face Unlock was still fast but what I was experiencing was seeing a slow sliding animation of unlocking the phone.

In the beginning I thought it was due some update, maybe OnePlus has added some more security measurement to the process, a week ago when one of my colleagues bought a 5T.

His brand new setup was running on the latest Oxygen OS and the Face Unlock was fast. this made me think about what could be on my phone and not on his that causes this issue and the only thing I could think of was my launcher. I am not using the Default launcher shipped by OnePlus on my device, I am running on Microsoft Launcher, so I thought that’s it, catch ya. But I eventually realised that the devilish animation is not coming from my launcher either.

Well after some search it turned out that the issue was due to change in animation speeds in my phone when I activated my Developer mode. I do not remember changing any of these settings but looks like activating developer mode made following settings to get the default value of 1x.

So if you are experiencing slow face unlock or finger print process on your OnePlus 5T and you’ve activated the developer mode sometime during your usage, I highly suggest you to have a look at these settings.
