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.
Add More Details to a Contact
If your contact list only shows a name and phone number, you are missing space for details like birthdays, addresses or website links. On Huawei phones, this extra information lives on the same contact card, but the fields for it stay hidden until you open edit mode. Many users never notice they exist.
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.
Location Scanning via Wi-Fi and Bluetooth
Even with Wi-Fi and Bluetooth switched off, your Huawei phone can still run short scans of nearby networks and devices to pinpoint your location. This happens whenever an app with location permission asks for the most accurate fix available, no matter what your radio toggles say. The scanning behavior sits in a separate setting from the Wi-Fi and Bluetooth switches themselves, which is why turning those off doesn't stop it.
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.
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.
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.
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.
