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.
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.
Choose or Add a Backup Account
Google Drive only stores photos, contacts and app data once EMUI knows which Google account should receive the backup. If no account is linked yet, or the wrong one is selected, Backup & restore looks active but stays empty. This mix-up is common on phones that were set up with a second or work Google account.
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.
Check for Security Updates Manually
If the security update notification on your Huawei phone got dismissed or never showed up, you might be running on an outdated patch without knowing it. This leaves known vulnerabilities unpatched until the next automatic check happens, which can take a while depending on your network and settings. A manual check confirms whether a new patch is already available for your device.
Manage Do Not Disturb Access for Apps
If an app on your Huawei phone keeps buzzing through Do Not Disturb, it has been granted permission to bypass that mode entirely. This usually happens after you approved a notification-related prompt without noticing what it actually allowed. Once granted, the app can send alerts, calls or messages even while your phone is set to stay silent.
Change the Region Setting
On many Huawei phones the region field switches on its own whenever the device connects to a different mobile network. This can happen right after a trip abroad or when a SIM briefly loses signal and reconnects to a foreign carrier. The automatic change can affect app stores, weather data, and date formats without any warning.
Enable or Disable the Number Row
On most Huawei phones the keyboard only shows letters, so typing a phone number or a password with digits means switching to the symbols page every time. SwiftKey Keyboard has a number row option that keeps the digits visible above the letters, but it sits deep inside the typing settings and is easy to miss.
Change the App Lock PIN
If apps behind App Lock keep asking for an old code, or you want a stronger PIN, remember that App Lock on Huawei phones runs separate from your screen lock. You can update it directly inside the App Lock settings, but only after entering the current app lock code. Forgetting that code is usually what stops people before they even reach the option to change it.
