User level: Level 1 (12 points)Hi, I installed iOS 27, and since the update, I have been receiving temperature alerts and experiencing intermittent network disconnections. I have already performed a hard reset, but the issue persists. The phone does not appear to be overheating, and its temperature feels normal.

Which iPhone are you using?
To rule out a software issue, set the iPhone back to factory settings and set it up as a new device, without using the latest backup. Then test it again.
Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support
If the messages do not come back, restore from the latest backup and test it again.
In case you are still seeing those messages after setting it up as a new device, you should contact the official Apple Support, they can diagnose your iPhone online.

If this even starts while resetting your iPhone, you should definitely contact the official Apple Support to get it diagnosed online, or visit an Apple Store / Authorised Apple Service Provider next to your place and let them check it:
