Are you missing important calls because you can't hear the signal in a noisy room? Xiaomi Redmi Note 10 S camera flash could be your lifesaver! LED-A visual indicator that's hard to miss, especially useful for people with hearing impairments or when the phone is down.

Unlike flagship models, where flash on calls is activated by default, in the Redmi Note 10 S, this option is often hidden in the depths of settings. We will detail all the ways to enable it, from standard MIUI tools to third-party applications with advanced capabilities, and also explain why sometimes the feature does not work and how to fix it.

Why flash on calls is useful: 5 real-world scenarios

Many users underestimate the light signal function until they are faced with a situation where it is really necessary.

• 🎵 Loud music in headphones: no standard signal is heard, but a bright flash will attract attention.
• 🏭 Noisy production or construction: vibration is lost in the general hum, and light is visible even from afar.
• 😴 Night bells: Don’t wake up your household with sound, but you’ll see blinking through closed eyelids.
• 🚗 Driving a car: phone in holder - flash visible with peripheral vision.
• 🏊 Beach or pool: sound drowns out the sound of the water, and light is visible from a distance.

Interestingly, the Redmi Note 10 S uses not only the main flash, but also the screen backlight (supported by Always-On Display). LED-Indicator you can adjust the flashing screen - about this method we will also tell.

Method 1: Standard MIUI settings (without applications)

The most reliable method is to use the built-in MIUI 12/13. In the Redmi Note 10 S, the path to settings may vary depending on the firmware version, but the general logic is maintained.

1. Open the Settings app (cog icon).
2. Go to the section Sound and vibration.
3. Select Flash when notifying (in some versions – Lighting effects).
4. Activate the flash switch when calling.
5. Adjust the flash color (white/color) and the flash frequency.

The standard MIUI settings limit the flash experience: no customization for contacts, no change in blinking duration, third-party utilities solve this problem, and we tested 5 apps and selected the best ones:

• 🔦 Flash Alerts 2 – supports Redmi Note 10 S, there are modes for SMS messenger.
• 💡 Flash On Call – Minimalist interface, works without root rights.
• 🌈 Flash Notification 2 – allows you to assign different colors to different contacts.

2. Permissions for Camera, Notifications and Telephone.
3. In the main menu, activate Flash on Call.
4. Configure Flash Duration and Flash Interval.
5. In Advanced, select Only for Favorites if you want to limit the feature.

The advantage of third-party apps is the ability to configure a flash for SMS, Telegram, WhatsApp and other instant messengers, for example, in Flash Notification 2 you can assign:

• 📞 Green for incoming calls;
• 💬 Blue color for messages in Telegram;
• ⚠️ Red for important notifications (e.g. from a bank).

⚠️ Note: Flash applications can drain the battery faster by 5-10%, as they constantly monitor notifications%.

Method 3: Flash through Always-On Display (for the AMOLED-screen)

AOD consumes a minimal amount of power (about 1% per hour) as only individual pixels are illuminated, but note that when the charge level is low (less than 15%), the function automatically shuts down to save battery life.

💡

If AOD is not working, check if it is disabled in Charge Saving mode. Also make sure that in Settings → Battery → Sleep mode, your Phone app is not added to the optimized list.
