Enable or Disable Wireless Projection
If your Huawei phone refuses to mirror onto a TV or receiver, wireless projection is either switched off or the two devices are stuck on different networks. The feature works like the screen-mirroring apps you get from third parties, only it needs no extra install and talks directly to Miracast-certified TVs and receivers. It only shows results once your phone and the display share the same Wi-Fi network.
Lock the Home Screen Layout
Dragging an icon by accident on your Huawei home screen can undo hours of careful arranging. EMUI has a Lock layout option that freezes every app and widget in place once you are happy with the setup. Without it, a stray swipe, a kid grabbing your phone, or an app update can shuffle everything again.
Reject a Call with a Quick Response Message
When you can't take a call but still want the caller to know why, a plain decline leaves them guessing. On Huawei phones running EMUI, the incoming call screen offers a message option that sends a short text back instead of just hanging up. This way the caller gets an automatic reply like 'Calling you back later' without you saying a word.
Enable or Disable WiFi and Bluetooth Location Scanning
If your Huawei phone keeps pinpointing your location even with GPS switched off, WiFi and Bluetooth scanning is likely doing the work in the background. This feature checks nearby networks and devices to sharpen location accuracy, but it can also drain battery and raise privacy concerns. Both signals can be controlled separately from the location settings.
Allow Messages in Do Not Disturb
Messages still light up the screen or buzz the phone even though Do Not Disturb is switched on. EMUI treats calls and messages as separate exceptions, so muting calls alone does not silence texts. A dedicated Messages option inside Do Not Disturb decides who gets through and who stays blocked.
Set Default Calendar Reminder Time
Adding the same reminder to every new event in the Calendar app gets tedious fast. If you keep picking 10 minutes before or Start time of an event manually each time, a single setting can handle it for you going forward.
Set a Custom Lock Screen Signature
If your Huawei lock screen still shows the name from your business card instead of your own text, the default signature setting is active. Many people only notice this after setting up their device, when a stranger's name or generic label appears every time the screen wakes up. This can be replaced with any text you want, including contact details for a lost phone.
Block Pop-ups in the Browser App
Websites that need extra tabs, like login windows or file downloads, may fail to open if the browser's pop-up blocker is active. On Huawei phones running EMUI, the Browser app blocks pop-ups by default, which can break certain site functions. You can turn this protection on or off directly in the browser's settings.
Delete a Calendar Event
When an event no longer applies or two appointments overlap, you need to remove it from the Calendar app on your Huawei phone. If the event repeats, EMUI asks whether to delete only this occurrence or every future instance of the series. Picking the wrong option can wipe out appointments you still need.
Disable App Lock
If you no longer want a PIN or password prompt every time you open certain apps, the built-in app lock on your Huawei phone can get in the way. Removing it requires confirming your current unlock code first, otherwise the option stays greyed out. Once switched off, all previously locked apps open normally again without any extra prompt.
Manage App Permissions
If an app on your Huawei phone keeps asking for camera, location or contact access even though you never approved it, the permission was likely granted automatically or by mistake. Once several apps hold broad access, tracking who can use your microphone or storage becomes hard. Reviewing and adjusting each permission individually is the only way to see exactly what an app is allowed to do right now.
Delete a Single Entry from the Call List
Clearing your entire call history wipes out every logged call at once, even the ones you still needed. On Huawei phones the Phone app also lets you remove just one entry, so the rest of your history stays intact.
Archive Conversations in Messages
When your inbox fills up with old chats you still need but do not want to see every day, it gets hard to find new messages fast. Deleting them is not an option if you need to keep the content, so a way to hide them without losing them helps. Huawei Messages has a built-in archive for exactly this case.
Decrypt Memory Card
If you encrypted your memory card on a Huawei phone to protect its data, other devices like tablets, laptops or a different smartphone cannot read it until the encryption is reversed. This usually shows up as an unreadable, empty or unrecognized SD card when you insert it into another gadget. The decryption has to happen on the same Huawei device that originally encrypted the card, since the protection is tied to that hardware.
App Permission Manager
If you are not sure which apps on your Huawei phone can access the camera, microphone or contacts, the permission overview is easy to lose track of. Many apps request broad access during setup, and it is not always obvious afterwards which function is actually still active. A dedicated permission manager lets you check and adjust this per function instead of digging through every single app.
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.
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.
Reset Camera Settings to Default
Blurry photos, wrong aspect ratios, or a filter you can't turn off often trace back to settings you changed inside Huawei's Camera app. Instead of hunting through every option manually, you can restore the entire camera configuration to its factory state. Your saved photos and videos stay untouched during the reset.
Factory Reset Phone
If your Huawei phone has slowed down, keeps freezing, or you are about to sell or hand it over, wiping it back to factory settings usually fixes the root cause in one step. A factory reset removes your Google account, all system and app settings, installed apps, and every file stored in internal memory. Back up anything you need before starting, since none of this data can be recovered afterward.
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.
Disable Developer Options
If Developer options stay active on your Huawei phone, background tools like USB debugging or forced GPU rendering keep running long after you finished testing. That leaves debugging access open to any app or cable connection, and some of those settings quietly affect animation speed and battery behavior. The toggle for this sits inside a menu that only shows up once you have unlocked it yourself.
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.
Create a Folder on the Home Screen
When your Huawei home screen fills up with scattered app icons, finding the app you need turns into a scroll-and-search game. Grouping related apps into a folder clears space and keeps similar tools together. EMUI builds this folder automatically once you combine two app icons.
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.
