Accounts & Cloud

Delete a User Account

If several people share the same Huawei phone, each extra user gets a separate profile with its own apps, photos, and settings. Only the device owner or an administrator can remove one of these profiles, and doing so wipes every file and setting tied to that account for good. Before you remove a profile, it helps to know exactly where the delete option sits and what data disappears with it.

Open
Network & Connectivity

Limit Maximum Hotspot Connections

If your Huawei phone's mobile hotspot allows up to eight devices to connect at once, uninvited users or unnoticed background traffic can quietly eat into your mobile data plan. Lowering the connection cap gives you a clearer picture of who is actually using your hotspot and how much data each session pulls.

Open
Calls & Messages

Enable or Disable Quick Calling

On some Huawei phones, holding the volume down key and saying a contact name starts a call even while the screen is off. If that happens by accident in your pocket, or if you want that shortcut but cannot find it, the Quick calling function is the setting responsible.

Open
Storage & Backup

Back Up to Google Drive

If you are not sure whether your Huawei phone is actually saving contacts, photos, and app data anywhere, the Back up to Google option in system settings might be switched off. Without an active backup account selected, restoring your data after a factory reset or device swap becomes much harder.

Open
Network & Connectivity

Restrict App Downloads to WiFi Only

If apps keep downloading or updating over your mobile connection and eating into your data plan, the Play Store app download preference is likely set to allow any network. This setting exists separately from your phone's general mobile data controls, so switching off mobile data elsewhere will not stop it. Adjusting the download preference inside the Play Store settings gives you direct control over when new apps and updates are pulled onto your Huawei phone.

Open
Network & Connectivity

Set Default SIM for Mobile Data

On a Dual SIM Huawei phone, mobile data can silently switch to the wrong SIM card, leading to unexpected charges or slower speeds. This happens when EMUI has never been told which SIM should handle mobile data by default. Without a fixed assignment, the phone may keep using whichever SIM was configured last.

Open
Apps & Installation

Enable Smart Data Saver for Individual Apps

If messaging apps stop pushing notifications or emails only load after you open them manually on your Huawei phone, Smart Data Saver is probably throttling their background data. Once the feature is turned on, every app loses background access to mobile data unless you add it to the exception list. Apps you rely on for real-time updates need to be excluded manually, otherwise they only refresh when active in the foreground.

Open
Accessibility

One-Handed Mode Setup

Reaching the top corners of a large Huawei display with one thumb is often impossible, and the built-in One-Handed mode shrinks the interface so every icon stays within reach. If the shrink gesture stops working or the mini window lands on the wrong side, the Accessibility feature usually just needs a quick toggle.

Add a New Alternate Look for Face Recognition

Changed your hairstyle, started wearing glasses, or grown a beard, and now Face Unlock on your Huawei phone keeps failing or asking for your PIN instead? Face Recognition compares your face to a single stored look, so a noticeable change in appearance can throw off detection. Registering an alternate look lets the system recognize both versions of your face without retraining the whole feature.

Open
Display & Home Screen

Delete a Theme

If the Themes section on your Huawei phone is packed with old designs you tried once and forgot about, finding the one you actually use gets tedious. Every downloaded theme keeps taking up storage and clutters the 'Me' tab until you remove it by hand.

Open
Accounts & Cloud

Manage Displayed Calendar Accounts

If your Calendar app shows events from an account you no longer use, or hides appointments from one you actually need, the account sync settings inside the app are usually to blame. Huawei lets you turn individual accounts on or off for calendar display, but this toggle sits inside the app menu rather than the main system settings, so it's easy to miss. Knowing which accounts feed your calendar helps you keep the view relevant and avoid missed appointments.

Open
Other

Enable or Disable Camera Flash

If your photos come out too dark or the flash keeps firing at the wrong moment, the flash setting in your camera app is probably not matching what you need. Huawei lets you force the flash on, switch it off completely, or leave the decision to automatic mode, which uses the built-in light sensor. Picking the right mode makes a real difference for indoor shots and quick snaps in bright daylight.

Empty the Recycle Bin in Gallery

Deleted photos on a Huawei phone stay in Recently deleted for 30 days and still take up storage space in the meantime. If you want a clean overview right away instead of waiting for the automatic cleanup, you need to clear that folder manually.

Create a Contact Group

If your contact list on a Huawei phone keeps growing, finding the right people for a group text or a shared ringtone gets messy fast. Without a dedicated group, you end up selecting contacts one by one every time you want to message a team, a family circle, or your closest friends. EMUI lets you bundle contacts into named groups, but the option sits a few taps away from where most people expect it.

Open
Notifications & Focus

Set a Custom Notification Sound Per App

If every app on your Huawei phone shares the same notification sound, you cannot tell a Messenger ping apart from a WhatsApp alert without checking the screen. EMUI lets you assign a separate sound to each app, but the option sits inside that app's own notification settings, not in one shared sound menu. Missing this step means every app keeps making the same noise no matter what you change in the general ringtone settings.

Open
Accessibility

Enable or Disable TalkBack

If tapping the screen suddenly triggers spoken descriptions instead of opening apps, TalkBack is active on your Huawei phone. This screen reader changes how touch and swipe gestures work, which can make the phone hard to use if you did not turn it on intentionally. Knowing where the TalkBack switch sits helps you enable it for voice guidance or shut it off fast.

Open
Other

Enable or Disable Silent Mode

When silent mode is active on a Huawei phone, calls, messages and notification sounds stop playing entirely, even at full volume. Many users trigger this by accident through a side button combo or a quick settings tile, then wonder why the phone stays quiet.

Open
Display & Home Screen

Show or Hide Carrier Name in Status Bar

If the carrier name keeps showing up next to the notch on your Huawei phone, the status bar can look crowded fast. On Dual SIM devices both operator names stack on top of each other, making the display area feel even tighter. This setting controls whether that label appears at all.

Open
Display & Home Screen

Apply a Downloaded Theme

Downloading a wallpaper pack or icon set from the Huawei theme store does not change your home screen by itself. If your phone still shows the old layout after a download, the theme sits unapplied in the theme library and needs one more step to take effect.

Open
Calls & Messages

View Call History for One Contact

Your Huawei call history mixes every call together, so tracking how often you have talked to one specific contact means scrolling through the entire list. Instead of filtering manually, the Phone app can pull up a focused call log for that contact. This same screen is also where you clear that person's call records without touching the rest of your history.

Open
System & Settings

Choose a Print Service

When you try to print a PDF form or document from your Huawei phone, nothing happens if no print service is active. EMUI ships with a default printing option, but it stays switched off until you enable it in the system settings. Without an active print service, the print button in apps like Files or a browser stays grayed out even if a printer is already on your network or paired over Bluetooth.

Open
Photo, Video & Media

Create a Photo Album

Scrolling through hundreds of unsorted pictures in the Huawei Gallery app makes it hard to find specific shots fast. Without separate albums, vacation photos, screenshots and everyday snaps all pile up in one long timeline, and older memories get buried within days.

Open
Photo, Video & Media

Hide an Album in Gallery

Vacation photos or old screenshots keep cluttering the main view of your Gallery app, even though you rarely open them. Huawei EMUI lets you tuck entire albums out of sight without deleting a single file. The albums stay on your phone, just out of the default overview.

Open
Storage & Backup

Set Priority Storage on SD Card

If your Huawei phone keeps filling up internal storage even with an SD card inserted, the camera app might still be saving new shots to the phone by default. A priority storage setting decides where single photos and videos land, but burst series and similar shots often skip that rule and stay on internal memory anyway.
