• Corrupted iOS or software update: One of the causes of your malfunctioning iPhone is a bad software or iOS update, like the iOS 15 this year. Your iOS is responsible for all of your iPhone’s functionality, so if there is a bad or corruptted file it can cause a number of issues including being stuck on the Apple logo.

  • Low Quality Jailbreak: Another reason could be a low quality Jailbreak. If you used software to jailbreak your iPhone, then it might have caused issues with the operating system. Jailbreaking isn’t certified or supported by Apple, so it can be quite easy to accidentally damage or corrupt files during the process.

  • Bad Hardware: Damaged hardware could also be the cause of this issue as your phone is heavily reliant on the parts that run it. Hardware can be damaged by repeatedly dropping the phone and it can even be worn out by regular use. Sometimes, some hardware issues can also cause the iPhone screen to blink with Apple logo.
