I have a iPhone 6s plus, but the new 11.1.2 has an update for bugs is specifically for the iPhone X. Do I still need to update? Thanks!

Hi.

Let your iPhone decide.

Go to Settings / Software update.

If your iPhone sees the update and asks you to download and install, give your iPhone the permission to do it.

Although the main features in the update point to iPhone X, there may be security and small bug fix elements in the update file for your iPhone, too.

I updated my iPhone SE the day when the update was released to the public.

Hope this helps.

It's always highly recommended to install the latest iOS version on your device, because there are also security patches.

good but not good enough,

You're welcome, srthomasva.

Have a nice day.
