When your laptop screen flickers upon placing a smartphone nearby, it is likely due to electromagnetic interference (EMI). Here are a few possible reasons that can help explain this phenomenon:
1. Magnetic fields: Smartphones and other electronic devices emit electromagnetic fields, which can interfere with the display signals of your laptop. This interference can lead to screen flickering or distortion. Magnetic fields are typically generated by components like speakers, antennas, or other elements within the smartphone.
2. Proximity sensor interference: Some laptops incorporate proximity sensors that automatically adjust display brightness or turn off the screen when an object is detected nearby. If the smartphone's presence triggers the laptop's proximity sensor, it may cause the screen to flicker.
3. Grounding issues: When there is a grounding problem with either your laptop or smartphone, it can result in electrical interference, leading to screen flickering. This issue can arise when the laptop and smartphone are connected to different power sources or when there are faulty grounding connections. To address this issue, you can try the following steps:
1. Increase the distance between your laptop and smartphone to minimize electromagnetic interference.
2. Ensure that both devices are properly grounded and connected to reliable power sources.
3. Update your laptop's graphics drivers and firmware, as outdated software can sometimes contribute to screen flickering. If the problem persists or worsens, it is advisable to seek assistance from a professional technician or contact the customer support of your laptop manufacturer for further guidance.
