Automatic Overnight Update Installation
If your Huawei phone restarts on its own overnight, an automatic install feature is likely running in the background. This setting controls whether downloaded software updates get installed while the device sits idle, separate from the download step itself. Turning it off still lets updates download automatically, but you decide when the install happens.
Enable Complex Calculator Functions
The default calculator on most Android phones only handles basic arithmetic, so many users search the Play Store for a scientific calculator app just to get functions like sine, cosine, or logarithms. On Huawei phones running EMUI, that extra download is unnecessary, but switching to the extended mode is not obvious if you only ever use the calculator in portrait orientation. The trigger sits in how you hold the phone, not in a hidden menu.
Rename a Paired Bluetooth Device
Bluetooth headphones or speakers often show up in your paired devices list with nothing but a cryptic model number. Once you have paired several accessories on your Huawei phone, telling them apart becomes guesswork. A custom name for each device fixes this without any extra app.
Send an SMS Message
On Huawei phones, SMS and MMS no longer appear as separate message types in the inbox. As soon as you attach a photo or another file, the message automatically switches from a plain text SMS to an MMS. This can be confusing if you are trying to find an old text or wondering why a message suddenly used mobile data instead of your text plan.
Choosing a Camera Filter
Scrolling through the camera filters can feel confusing when you are not sure which style actually fits your shot. Whether you want a warm 'Valencia' tone, a moodier 'Halo' look, or something softer like 'Dawn', each filter shifts the color grade before you even press the shutter. Picking one at random often means retaking the photo with a different look afterward.
Set a Custom Ringtone
If every call still sounds like the factory-installed tone, the personal MP3 you copied over USB or downloaded to your Huawei phone is not showing up where you expect it. The stock ringtone list only pulls from a specific storage location, so a file saved in the wrong folder simply gets ignored. Once you know which folder EMUI actually scans, picking your own track takes seconds.
Zoom In or Out in the Camera App
Framing a shot with the classic two-finger pinch can feel imprecise, especially when you want a small, steady zoom adjustment. Many Huawei camera users overlook that a second control exists right on the screen edge, which makes fine-tuning zoom much easier once you know where to look.
Enable or Disable Screen Saver
If your Huawei phone's display stays completely black while charging instead of cycling through photos, the screen saver feature is probably switched off. Even when it's active, a missing picture source or a short playback duration can make it look like the feature isn't working at all.
Add a Birthday to a Contact
Saved contacts on your Huawei phone often stay incomplete right after you save the first number. Without a birthday field filled in, your phone can never remind you when that date comes around. Adding it later takes a few taps in the contact details.
Clear Cookies in the Browser App
If the Huawei Browser keeps you logged into sites you already signed out of, or a website shows an old version no matter how often you refresh, stored cookies are usually the cause. The Browser app on EMUI lets you clear just the cookies without wiping your saved passwords or bookmarks.
Set Default Keyboard
New keyboard app installed but Swiftkey keeps popping up instead? Huawei phones use Swiftkey as the default keyboard, and extra keyboards you install do not switch on by themselves. You need to activate the keyboard you want before it shows up when typing.
Enable or Disable Eye Comfort
Harsh white light late at night can strain your eyes fast, especially when you are reading on your Huawei phone in a dark room. Eye Comfort shifts the display to warmer tones and reduces blue light, but the toggle and the automatic schedule option are easy to miss in the settings. Without it active, your screen keeps its full brightness and cool color temperature no matter the time of day.
Add a Printer Manually via IP Address
If your Huawei phone lists no printers during the network scan, the WLAN or WiFi Direct discovery has failed to reach the device. This happens on isolated subnets, guest networks, or with printer models that block broadcast discovery. Adding the printer by its IP address skips the automatic search entirely.
Switch Between 12-Hour and 24-Hour Time
If your Huawei phone displays 3:45 PM instead of 15:45, or the other way round, the clock format is likely tied to your system language rather than a fixed choice. This dependency means switching language can silently change how time appears on the lock screen, notifications, and widgets. A manual toggle for 24-hour time removes that guesswork.
Restrict App Access to Mobile Data or Wi-Fi
If a video streaming app keeps burning through your mobile data plan even when you are not actively watching anything, background network access is usually the cause. Some apps also switch between Wi-Fi and mobile data without asking, which drains your data allowance faster than expected. You decide per app whether it may use mobile data, Wi-Fi, or both.
Change the System Language
If your Huawei phone still runs in the language you set up years ago, you don't have to reset the device to fix that. EMUI lets you add extra languages under Language and region, but a newly added language stays inactive until it's moved to the top of the list. Skip that step and the phone keeps using the old language no matter how many times you pick the new one.
Screen Lock Tone: Enable or Disable
Every time you lock your Huawei phone with the power button, a short click plays and there is no obvious switch for it inside the main sound menu. If that beep annoys you, or it suddenly disappeared after you changed a sound profile, the toggle actually sits inside a secondary settings screen. Keep in mind the tone stays silent automatically whenever your phone is set to Mute or Silent, even if the toggle itself is turned on.
Restore Deleted Contacts
Accidentally deleted a contact on your Huawei phone and now it seems gone for good? EMUI actually keeps deleted contacts in a temporary folder instead of removing them right away. That window closes automatically after a set number of days, so the contact becomes unrecoverable once it expires.
Show or Hide Carrier Name on Display
If the carrier name of your SIM card keeps showing up next to the signal icon on your Huawei phone, that comes from a display option tied to your SIM setup. Some people want that label visible to tell dual-SIM slots apart at a glance, others find it clutters the status bar. Either way, the toggle sits in a display menu that is easy to miss.
Wake Screen for Notifications
If your Huawei phone display stays black when a new message or notification arrives, the wake screen option is likely turned off. This setting controls whether the screen lights up automatically for incoming alerts, separate from your normal lock screen timeout. Without it, you only see new notifications after pressing the power button yourself.
Enable Gentle Notifications for an App
Every notification on your Huawei phone triggers a sound, a vibration and a full pop-up by default, even for apps you only check occasionally. If a chat or news app keeps interrupting you but you still want to see missed messages later, muting it completely removes that overview. Gentle notifications quiet the alert while keeping a discreet trace of it in the notification panel.
Enable Read in Background for Select to Speak
If Select to Speak stops reading the moment you switch to another app on your Huawei phone, the background reading option is turned off. This feature is still experimental and can behave unpredictably in some apps.
Turn Off Keyboard Usage Statistics Sharing
If your Huawei phone keeps sending keystroke patterns and app usage data back to Microsoft SwiftKey, the Help improve Microsoft SwiftKey option is switched on by default. This setting shares what and how you type to refine the keyboard, which raises privacy concerns for many users. You can review and turn it off directly from the keyboard settings.
Allow or Deny Picture-in-Picture for an App
If a video freezes the moment you switch to another app, or a floating window never shows up while you type a message, the picture-in-picture permission for that app is probably the issue. Some apps get this permission by default, others need it turned on manually before the pop-up window works. Checking which side an app is on saves a lot of guessing.
