Reset Network Settings
If WLAN keeps dropping, mobile data refuses to reconnect after switching networks, or Bluetooth pairings act up for no clear reason, a stuck network configuration is usually behind it. Resetting network settings wipes WLAN profiles, mobile data setups and Bluetooth pairings so the phone rebuilds them from scratch. On Dual SIM phones you also get to pick which SIM card the reset applies to.
Set Up Private DNS
On public or shared Wi-Fi, every domain your phone looks up travels as plain text, letting the network operator or anyone else on the connection see which sites you visit. Huawei phones ship with private DNS switched off by default, so this exposure continues until you activate an encrypted resolver. Turning it on requires the exact hostname of a DNS provider, not just an IP address.
Turn Outgoing Message Sound On or Off
Every message you send from a Huawei phone plays a short confirmation tone by default. In quiet environments or during calls, that sound can feel out of place. The setting controlling it sits inside the Messages app itself, not in the general sound settings, which is why many people can't find it right away.
Turn Alarm On or Off
If your alarm doesn't ring in the morning, chances are the switch got flipped off by accident, not the alarm itself getting deleted. Huawei phones keep every alarm you set stored in the Clock app, so you never have to rebuild the same wake-up time from scratch. Knowing exactly where that switch sits saves you from re-entering the time, label, and repeat days over and over.
Quick Prediction Insert: Enable or Disable
If Huawei's SwiftKey keyboard inserts a suggested word the moment you tap the space bar, quick prediction insert is active. This happens before you finish typing the word yourself, which can break sentences you did not mean to autocomplete. The feature only works when autocorrect is turned on.
Show Battery Percentage
If your status bar only shows a plain battery icon with no numbers, you are left guessing how much charge your Huawei phone has left. EMUI hides the exact battery percentage by default and only displays a rough fill level. Turning this option on replaces the guesswork with a precise readout right in the status bar.
Enable or Disable Auto-Download Updates over WiFi
If your Huawei phone keeps grabbing software updates the moment it connects to WiFi, storage fills up before you even decide to install anything. On the other hand, if updates never seem to download on their own, this WiFi-only auto-download setting is usually the reason. Either way, the update only gets fetched, not installed, until you confirm it.
Enable or Disable Google Play Protect
If Google Play Protect keeps flagging a trusted app as harmful or blocks an install you actually want, the scanner is doing exactly what it's built for on your Huawei phone. It checks every app during and after download and rechecks apps from unknown sources on a schedule, then notifies you when it finds a risk. Switching it off stops the warnings, but it also removes that ongoing background scan from your device.
Assign a Picture to a Contact
If a contact still shows a generic icon instead of a photo when they call or text you, no picture has been linked to that entry yet. Huawei lets you attach either an existing photo from your gallery or a freshly taken picture to any saved contact. Without this link, calls and messages stay visually anonymous even after all other details have been saved.
Enable Emergency SOS Messages
If a Huawei phone does not send your location to trusted contacts during an emergency, the SOS message option under Security is probably switched off. Pressing the power button five times in a row is meant to trigger a call and an SOS text, but that only works once emergency contacts are saved and the message option is active. Without a saved contact list, the call still goes through, but no location text gets sent.
Enable or Disable VoLTE Calls
If your calls sound muffled or take a few extra seconds to connect, your phone is likely still routing them over the 2G or 3G network instead of 4G. Huawei phones fall back to the older network for voice unless VoLTE (Voice over LTE) is switched on, which also affects battery drain during calls.
Set a Custom Timer Tone
On a Huawei phone, the timer in the Clock app always shows a small bell icon next to the countdown, but many people never open it to pick a different sound. The default timer tone plays until you swap it out from the built-in sound list. Once you choose a new tone, it applies to every timer you start afterward, not just the current one.
Turn Auto-Download for MMS On or Off
MMS attachments on your Huawei phone download automatically the moment a message arrives, even over mobile data. If you are watching your data allowance or want to decide yourself when large files get pulled in, this automatic behavior can quietly use up bandwidth. The setting controlling this sits inside the Messages app and is easy to miss.
Enable or Disable Auto-Rotate Screen
When you tilt your Huawei phone sideways, the screen sometimes stays locked in portrait instead of switching to landscape. This usually happens because Auto-rotate got switched off, either by accident or through a stray tap in the quick settings panel. Without it active, apps like your gallery, browser or video player will not adjust to how you actually hold the phone.
Reset Advertising ID
If ads on your Huawei phone feel oddly specific, the Advertising ID stored on your device is the reason. Apps and ad networks use this identifier to link your browsing and app behavior over time, even across different services. Resetting it breaks that chain and hands you a new, unlinked ID.
Choose or Add a Backup Account
Google Drive only stores photos, contacts and app data once EMUI knows which Google account should receive the backup. If no account is linked yet, or the wrong one is selected, Backup & restore looks active but stays empty. This mix-up is common on phones that were set up with a second or work Google account.
Enable or Disable Switch Access
If touch gestures are not reliable for you, standard navigation on your Huawei phone turns into a real barrier. Switch Access lets you select items, scroll and type using one or more external switches instead of tapping the screen. Those switches connect via USB or pair over Bluetooth, but the toggle for the feature is tucked away in a menu most people never open.
Show SIM Card Messages
Old text messages you sent or received years ago sometimes disappear from your inbox after a SIM swap or a factory reset, even though they still physically sit on the SIM card. Huawei phones do not display these by default because the Messages app only loads device storage first. They are not deleted, just hidden from the normal conversation view.
Send a File via Bluetooth
When a Bluetooth transfer just sits there or the receiving device never shows up in the list, it usually means the two phones were never paired first. Bluetooth sharing on Huawei phones runs through the system Share menu, so picking the wrong app or an unpaired device stops the transfer before it starts. This guide walks through sending a single photo, though the same steps work for videos and other files too.
Enable or Disable Key Pop-ups
When you type on a Huawei phone, every letter you tap flashes briefly above the key before it appears in the message. In apps like WhatsApp or Messenger this preview can feel distracting, especially if you type fast or use a small screen. The behavior comes from a keyboard setting, not from the messaging app itself.
Enable or Disable Find My Device
If your Huawei phone gets lost or stolen, you can only track it through Google's Find My Device tool when the feature was switched on beforehand. Many people only notice the setting is off after the phone is already gone. The location service also runs quietly in the background, which is why some users prefer to turn it off to save battery or for privacy reasons.
Set Phone Ringtone
If your Huawei phone still rings with the default tone after you picked a new one, the change probably landed on the wrong SIM slot. Dual SIM devices store separate ringtones for SIM1 and SIM2, so the tone you hear depends on which line is receiving the call. Video calling apps can also override the system ringtone with their own sound.
Set Preferred Network Type (2G/3G/LTE)
When LTE reception is weak, your Huawei phone can lose its data connection entirely instead of falling back to a stable signal. The preferred network type setting decides which mobile network your SIM tries to connect to, and picking the wrong option often causes dropped calls or painfully slow browsing.
Change Lock Screen Wallpaper
Picking a new photo for your Huawei phone does not automatically change what shows on the lock screen. EMUI treats the home screen and the lock screen as two separate wallpaper slots, so after choosing an image you still get asked where it should actually be applied. Pick the wrong option in that prompt and the old lock screen image stays exactly as it was.
