Take care of the cleaning and maintenance of your device

Often, the quality of video and voice calls is affected not by complex technological failures, but by a simple oversight: dirt, dust, or grease accumulated on the camera lens, speakers, or microphone . Even a tiny fingerprint can drastically reduce image sharpness or distort the sound.
- Carefully clean the front and rear cameras before making an important video call.Use a soft microfiber cloth to prevent scratches and remove dust, smudges, and grease.
- If you use screen protectors or camera covers, try removing them temporarily to check whether they affect visual quality. Some materials can interfere with the passage of light and reduce optical quality.
- Also pay attention to the speaker and microphone holes. Dirt can accumulate and clog them, affecting sound transmission. Clean them with a plastic stick or a fine needle very gently and under good light, avoiding pushing the dirt inwards.
- Avoid covering the speakers or microphone with your hand when holding the phone, as this reduces the volume and clarity of the call.
Optimize your internet connection for perfect calls and video calls

The foundation of any quality WhatsApp call or video call is a stable and fast internet connection . Problems such as delays, dropped calls, frozen video, or poor audio synchronization are usually due to unstable, slow, or congested networks.
- Always prioritize the use of a powerful and secure Wi-Fi network, especially indoors or where mobile coverage is spotty. Wi-Fi typically offers greater stability and speed than mobile data.
- If your router allows you to choose, connect to the 5 GHz band instead of the classic 2,4 GHz. The 5 GHz band offers higher speed and less interference, ideal for smooth audio and video streaming.
- If you only have mobile data, make sure you are in an area with good coverage and avoid spaces where the signal is weakened (basements, elevators, structures with thick walls).
- Avoid using public wifi networks For important video calls, as they tend to be congested, less secure, and can cause quality loss. If you must use them, position yourself as close to the access point as possible.
- Note that the use of VPNs or data-saving applications may reduce connection speed and stability, affecting call quality.
Extra tip : If possible, disconnect other devices that are using your Wi-Fi network to avoid competition for bandwidth and reduce latency.
Internal WhatsApp and system tweaks to improve quality

WhatsApp has a number of built-in options and system settings that directly affect audio and video quality . Many people are unaware of how these modes affect the quality and how to optimize them for the best possible results.
- Turn off "Use less data for calls" on WhatsApp: This feature, designed to save data on calls, reduces quality by compressing the audio and video stream. To improve your experience:
- Open WhatsApp and go to Settings > Storage & data.
- Turn off the “Use less data for calls” option.
- Turn off your phone's battery saving mode: Power saving mode limits device resources, such as CPU or background app activity, which can restrict the quality and stability of calls. To disable it:
- On Android: Settings > Battery or Device care.
- On iPhone: Settings > Battery > Low Power Mode.
- Check system data savingsIf you have Data Saver enabled on both Android and iOS, your phone will limit the transfer rate, affecting audio and video quality. To disable it:
- On Android: Settings > Connections > Data usage > Data saver.
- On iOS: Settings > Wi-Fi > (your network) > Low Data Mode and adjust accordingly.
- Manage WhatsApp permissions: Check that the app has permissions to access the microphone, camera, and network. Otherwise, audio and video capabilities may be restricted.
Making these adjustments both from the app and from the operating system's general settings helps avoid unexpected limitations and interruptions during your communications.
Keep WhatsApp and your phone always updated
Having the latest version of WhatsApp and your operating system is key to enjoying the greatest improvements in quality, stability, compatibility, and security . Each update typically brings specific optimizations to improve audio and video compression, fix bugs, and expand compatibility with new formats and devices.

- Also update your phone's operating system, as the new versions fix bugs, improve energy efficiency, and optimize the performance of apps like WhatsApp.
This simple routine can prevent many quality issues and incompatibilities, and ensure you have access to the latest features.
Select a suitable environment for your calls and video calls

The location where you make your calls or video calls has a significant influence on the final quality of the communication, even if the device and network are in optimal condition.
- Find a quiet, silent place without distractions, especially in important conversations or group video calls.
- Move away from background noise, televisions, music, or running appliances, as they can interfere with and hinder understanding.
- If the Wi-Fi signal is weak in one area of the house, Try changing rooms or placing your phone closer to the router. to improve coverage.
- In video calls, Avoid backlighting and look for good frontal lighting that allows us to clearly see your face and gestures, facilitating non-verbal communication.
- Use headphones or hands-free devices to reduce ambient noise picked up by the microphone and improve both sound reception and output.
Properly configure the volume and audio output devices
A common and very frustrating mistake is having the call volume too low or incorrectly configured . Most phones allow you to adjust the call volume independently of other phone sounds (notifications, music, alarms, etc.).
- Increase the volume using the side buttons while on a call, not before or after. This way, you can ensure you set the correct level for WhatsApp calls.
- If the sound is not enough, activate the speakerphone (hands-free)This will improve the power and clarity, but remember that those nearby will also be able to hear the conversation.
- If you use Bluetooth headphones or other audio devices, Verify that the call audio is not being sent to a disconnected external deviceYou can change the audio output from the call screen itself.
Avoid covering the speakers with your fingers or palms when holding the phone, as this significantly reduces the perceived volume.
Periodic cleaning and maintenance of speakers and microphones
Over time, it is common for the speaker and microphone holes to become filled with dust, lint, or dirt , which negatively affects the quality and clarity of calls and video calls.
- Perform regular cleaning with a thin tool such as a plastic stick or needle, under good lighting and with extreme care so as not to damage the internal components.
- Do not use aggressive liquids or very strong compressed air, as this could cause damage or force dirt deeper inside.
Restart your phone if you experience specific problems.
Sometimes, temporary glitches in the operating system or WhatsApp can cause dropped calls and video calls , even if everything seems to be set up correctly. Restarting your phone clears stuck or overloaded processes and can restore the app's smoothness and stability.
- Restart the mobile before making more complex changes if quality problems suddenly appear.
Clear WhatsApp cache to improve performance on Android
On Android devices, WhatsApp stores temporary files in the cache to speed up opening chats and using frequently used features. However, if these files become corrupted or excessively full, they can cause unexpected crashes, slowdowns, and affect the quality of calls and video calls.
- Press and hold the WhatsApp icon on your Android phone.
- Accede to App info > Storage > Clear cacheThis operation does not delete your messages or personal files.
Repeat this process periodically if you notice the app running slower than usual or if you experience specific quality issues.
Blur the background in video calls and use advanced effects

Additional solutions and recommendations for advanced cases
- In group calls, The quality will depend on the connection and devices of all participants.If someone has a bad connection, it can affect everyone.
- if you experience echo or double audio, ask participants to use headphones and avoid having the speaker close to the microphone.
- Disable other background apps that may consume bandwidth, resources, or frequent access to the microphone/camera.
- On older devices, reducing the number of open apps and freeing up memory can improve the experience.
