The headphone icon, which doesnβt disappear from the Xiaomi Redmi Note 9 screen even after the headset is removed, is a common problem among smartphone owners. The status bar symbol is not only visually annoying, but can block the sound through the speakers, redirecting it to a non-existent audio device, and the cause of the βghostβ icon lies in both software failures of the MIUI and physical malfunctions of the 3.5 mm jack or contacts inside the case.
In this article, we will discuss 5 proven ways to fix the problem, from a basic reboot to a deep cleaning of the system. Importantly, some methods require root rights or disassembly of the device, so assess the risks in advance. If you are not sure of your skills, you should contact the Xiaomi service center.
Why the headphone icon does not disappear: the main reasons
Before you start fixing, it is worth understanding what caused the crash. In the Redmi Note 9 (Note 9/9S/9 Pro/9T models), the problem is usually related to:

- π Conflict of the Software after Updating MIUI or custom-built.
- π§ Failure of the headphones themselves - if the headset with a microphone, its controller can "hang" when extracting.
In 80% of cases, the problem is solved software-free without disassembling the phone, but if the icon appeared after a mechanical impact (impact, water), there is a high probability of hardware damage.
