WhatsApp for Poco X5

WhatsApp plays voice messages through the earpiece (and blanks the screen) when the proximity sensor thinks the phone is near your ear. If it triggers while the phone is on a table or in your hand, the sensor at the top of the screen is likely dirty or blocked, so wipe the area around the front camera and remove any thick screen protector covering it. Make sure you tap the play button rather than holding the phone up. If a protector overlaps the sensor strip, that is the most common cause on the Poco X5. See how others solved this on Reddit

WhatsApp uses the proximity sensor for raise-to-ear behavior, and a blocked or faulty sensor on the Poco X5 can interrupt recording. Remove any thick screen protector covering the sensor strip near the front camera and clean that area. As a workaround, swipe the microphone icon up to lock hands-free recording so you do not need to hold the phone near your face. You can verify the sensor with a hardware test in Settings > About phone or a sensor-test app. See how others solved this on Reddit

This usually happens when Media visibility is off, so the files exist but are hidden from the MIUI/HyperOS Gallery. Open WhatsApp > Settings > Chats and turn on Media visibility. For a specific chat, open it, tap the contact/group name, and set Media visibility to On. If photos still do not appear, restart the phone so the media scanner re-indexes the WhatsApp Media folders.

WhatsApp's built-in camera uses a low-quality stream and heavy compression, so it always looks worse than the stock camera. Instead, shoot with the HyperOS Camera app, then in WhatsApp tap the attach (paperclip or +) icon > Gallery and pick the photo. To keep more detail, raise WhatsApp > Settings > Storage and data > Media upload quality to HD, or send the image as a Document to avoid compression entirely. See how others solved this on Reddit

Use Google Drive backup with the same Google account on both phones. On the old phone open WhatsApp > Settings > Chats > Chat backup and back up to Google Drive, then on the Poco X5 install WhatsApp, verify the same phone number, and tap Restore when prompted. If restore shows nothing, confirm both phones are signed into the identical Google account and that the backup actually finished before you reset the old device. See how others solved this on Reddit

HyperOS restricts background apps by default, which can block notifications. Go to Settings > Apps > Manage apps > WhatsApp, enable Autostart, and set battery saver/restrictions to No restrictions. In the same WhatsApp app info screen open Notifications and make sure Lock screen notifications are allowed. Also check Settings > Notifications & Control center (and Lock screen settings) so message content can display on the lock screen. See how others solved this on Reddit
