Lock Screen Notifications: Show or Hide
Anyone who picks up your Huawei phone can read message previews straight off the lock screen if notifications are set to show full content. That becomes a problem on shared desks, in meetings, or whenever you hand the phone to someone else for a moment. Huawei lets you keep alerts visible while hiding the actual text, or turn lock screen notifications off entirely.
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.
Manage Device Administrators
If an app refuses to uninstall or keeps triggering warnings about admin rights, it likely still holds device administrator status on your Huawei phone. Device administrator permissions let an app change system settings, lock the screen or wipe stored data - access many apps request without a clear explanation. Turning off the wrong administrator can break features like Find My Phone or a company profile, so you need to know exactly which app is authorized before switching anything off.
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.
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.
Block Unknown Numbers
Anonymous or withheld numbers keep ringing your Huawei phone even though you never answer them. This happens because call blocking for private numbers is turned off by default in the Phone app, so every masked caller gets through until you change that setting.
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.
Manually Select a Mobile Network
Near a border or in a rural area, your Huawei phone might latch onto a foreign network that offers a stronger signal instead of your home carrier. This happens because automatic network search always prioritizes reception over your default provider. Roaming charges or dropped data sessions are the usual result until you pick the carrier yourself.
Enable or Disable Dual Clocks
Travel to a different time zone with your Huawei phone and the lock screen suddenly shows two clocks side by side. That second clock reflects your home city time and keeps appearing until you switch the dual clocks feature off or update the home time zone yourself.
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 Automatic Data Backup
If your Huawei phone skips its weekly backup, the charger and battery level requirements are usually the reason. Auto-backup only runs while the device is plugged in and charged to at least 75 percent, so a missed connection means a missed backup. Checking the current setting is the fastest way to find out why your last backup never happened.
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.
Turn Wi-Fi On or Off
If your phone keeps burning through mobile data at home or at work, Wi-Fi might be switched off without you noticing. On the other hand, a Wi-Fi radio left running all day in areas with no network drains battery for nothing. Knowing exactly where this switch sits on your Huawei saves both your data plan and your battery.
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.
Resize the On-Screen Keyboard
If the SwiftKey keyboard on your Huawei phone feels too large for one-handed typing or too cramped to hit the right keys, the default layout is likely still active. Height, width and position of the keyboard can all be adjusted independently of each other. This becomes noticeable especially on larger displays or when you switch between portrait and landscape typing.
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.
