1. iOS Software Crashes: When the System Glitches

The first thing to check is the performance of the operating system itselfEven on iPhone Its closed ecosystem can cause glitches, especially after updates or when running for long periods without rebooting. Here are typical symptoms of software problems:

• 🔄 Wi-Fi disconnects after waking up from sleep mode
• 📶 The network icon is gray, but the connection is "active" in the settings.
• 🔁 Reconnection occurs only after manually turning Wi-Fi on/off
