Maybe that why 11.41 beta now Liao
I thought they said 11.4 was final until 12 comes out in September? Some more beta means 11.4 still a bit kok up...

That'll be the last resort. Now re-opened my case with an Apple advisor, awaiting other options.
Did that to no avail as well. But anyway I just had a chat session with Apple support, was asked to send a diagnostics of my phone to them and was told passed the test, so it’s a software issue. Was told that only way to resolve is to restore from a backup via iTunes as it will install back a fresh copy of iOS as compared to doing it via iPhone settings as it won’t install a fresh copy.
BTW all the time I’ve been using OTA for iOS updates.
how is the performance and battery life on your iPhone 6S on iOS 11.4? I am still on iOS 9.3.5 after hearing all the issues that came with iOS 10 and 11 albeit it was slowly rectified along the way I guess
So if I send a lot of message and image through I message. My storage not enough and I need to purchase more storage? Or I need to delete the message every now and then? As of now I don’t even need to delete .

Doesn't mean diagnosis test pass means no issue.. I once had a issue where NFC could not work at all even after software reset.
Went down to apple store and they did a 1-1 exchange.
Need ask for senior rank one
But if u got applecsre it will e much easy
What about 3rd party camera app ?
Your case similar to mine dad ip6 before was ok but after update to iOS 10 it’s cock the Touch ID even try to do a clean inDsll.no help in the end ask for a express exchange lucky I hoot applecsre for him
Never trust OTA, cable for assurance.
I did ask if OTA is less secure than from iTunes, was told both are equally safe.
Now, just monitoring.
Only the main camera app causing problems, 3rd party ones and those rewards apps or shopping apps no issues.
Ultimately was transferred to a senior advisor and was advised to restore iPhone via iTunes then test it out as a new phone. If working then restore the backup.

I just have this crazy idea that WiFi signals (which can become poor) cause instability when downloading the update package, causing it to be incomplete/corrupted.
But that's just me.
Hope all is ok for u bro
That's it, I'm bringing down my X to Apple Store after lunch today, but no Genius Bar appointment made.

I would suggest going down early morning when it opens. Especially on a weekend, with no appointment made, you probably need to wait for a few hours
also, bring the whole box in hopes of a 1-1 exchange.
Make sure if the exchange is made. the box is the retail box and not a white box.
I observed that the white box is a refurb set, not confirm though
Do it already bro. Best wishes. Fug it lah really. You deserve a good phone in working good order.... so that you can put it into a nice rhinoshield SS lol
