Colour Inversion
If colour inversion switches on by accident, a white background with black text flips to a black background with white text across the whole screen. Photos, videos and other media get affected too and can look washed out or plain wrong. This toggle sits inside the accessibility features, so it is easy to miss and just as easy to fix once you find it.
Enable or Disable Activity Controls
If Google keeps showing personalized search results and ads based on your browsing, an activity control like Web is switched on somewhere in your account. On EMUI phones you don't need a browser to check this, since the same setting sits inside the phone's own privacy menu. Turning it off stops that specific activity type from being saved and used for future recommendations.
Turn Flashlight On or Off
The LED flash next to your camera lens can double as a flashlight, but many Huawei owners cannot find a quick way to switch it on without opening the camera app first. The toggle actually lives in the notification shade, not in a dedicated app or settings menu. If the icon looks greyed out or does not react to taps, something else is usually blocking it.
Set Up Parental Controls with Digital Balance
If your kid is glued to their Huawei phone and homework keeps getting pushed back, screen time is probably the real issue. Huawei bundles parental control inside the Digital Balance feature, which most parents never open because it looks like a personal wellbeing tool. Without setting limits here, apps stay unrestricted and screen time goes untracked.
Enable or Disable Smart Cover Display Window
When you close a smart cover with a cutout window on your Huawei phone, the screen behind the window stays blank instead of showing the time or date. This happens because the Smart cover feature is switched off or the display window option inside it was never turned on. A related step counter toggle controls whether your daily steps show up in that same window.
Block Unknown Numbers
Anonymous or withheld numbers keep ringing your Huawei phone even though you never answer them. This happens because call blocking for private numbers is turned off by default in the Phone app, so every masked caller gets through until you change that setting.
Enable or Disable Dual Clocks
Travel to a different time zone with your Huawei phone and the lock screen suddenly shows two clocks side by side. That second clock reflects your home city time and keeps appearing until you switch the dual clocks feature off or update the home time zone yourself.
Enable or Disable Cell Broadcasts
Getting a flood of monthly test alerts on your Huawei phone, or missing a real emergency warning entirely? Both come down to the cell broadcast settings, which control AMBER alerts, extreme and severe threat notifications separately from your regular messages. Each alert type can be switched on or off on its own.
Enable or Disable Huawei Share
If you cannot send photos or files directly to another Huawei phone nearby, Huawei Share is likely switched off. The feature ships deactivated by default, so nearby devices will not detect each other until you turn it on. Once active, you can also enable Computer Share to move files between your phone and a PC or laptop on the same network.
Enable or Disable Google Autofill
If login fields, addresses or payment details fill in on their own, the Google Autofill service is active on your Huawei phone and pulling data straight from your Google account. Some users want that convenience back, others want it switched off after noticing sensitive data appearing in forms it should not touch. Either way, the setting sits in a place that is easy to miss.
Select to Speak Setup
If tapping the screen suddenly triggers a spoken read-out of text or images instead of opening an app, Select to Speak is active on your Huawei phone. Many users enable this accessibility feature by accident and then struggle to find where to switch it off again. The toggle sits inside a separate accessibility menu, not in the general sound or display settings.
Show Certification Logos
If you need the FCC ID or another regulatory marking for your Huawei phone but cannot find it on the box or in the manual, the certification logos are stored on the device itself. Which certificates show up depends on the exact model, so the list can look different from phone to phone. The entry is easy to miss because it sits deep inside the system menu.
Add or Remove Browser Bookmarks
Losing track of frequently visited pages in the Huawei Browser app is a common annoyance once bookmarks are missing or scattered without order. Without a saved shortcut, you end up retyping URLs or scrolling through browsing history every time you need a page again. The save option sits in a spot many people overlook, and removing old bookmarks later works differently than adding them.
Usage & Diagnostics Reporting Settings
If your Huawei phone keeps sending device and app data even though you thought you switched tracking off, the Usage & diagnostics setting is usually the cause. It controls whether diagnostic reports, crash logs and app usage details leave your device, separate from the checks needed for updates. Turning it off does not stop your phone from receiving system and security updates.
Quick Prediction Insert: Enable or Disable
If Huawei's SwiftKey keyboard inserts a suggested word the moment you tap the space bar, quick prediction insert is active. This happens before you finish typing the word yourself, which can break sentences you did not mean to autocomplete. The feature only works when autocorrect is turned on.
Enable or Disable Ultra Snapshot
If double-pressing the volume-down button on a locked Huawei phone does nothing, Ultra snapshot is probably switched off. This shortcut is meant to fire the camera or grab a photo straight from standby, but it only works when the feature is turned on in the camera app.
Enable or Disable Switch Access
If touch gestures are not reliable for you, standard navigation on your Huawei phone turns into a real barrier. Switch Access lets you select items, scroll and type using one or more external switches instead of tapping the screen. Those switches connect via USB or pair over Bluetooth, but the toggle for the feature is tucked away in a menu most people never open.
Set a Mobile Data Usage Warning
Running out of mobile data before the billing cycle ends usually means the usage reminder was never turned on. Without a warning threshold, EMUI stays silent until the allowance is already gone. A percentage-based alert or a daily limit notification gives you a heads-up before that happens.
Change Device Name
When you pair a Huawei phone over Bluetooth or plug it into a PC, it often shows up under a generic factory name instead of something you actually recognize. That default label makes it hard to tell your phone apart from other devices on the same network or in a list of paired accessories. Renaming it fixes that identification problem for good.
Enable Desktop Site in Browser
Websites open in a scaled-down mobile layout on your Huawei phone, and some buttons or menus stay hidden because of that. Online banking portals, admin panels or older shop systems often only show their full feature set once the desktop layout loads. The browser normally switches back to mobile view on its own after you close the tab or leave the page.
Enable or Disable Advanced Visual Effects
Menus that fade in and out, icons that bounce, apps that animate on launch - these transition effects look nice but can make a Huawei phone feel sluggish, especially on older models. If your device lags while switching between screens or opening apps, the Advanced visual effects setting is often the reason.
Add a New Browser Tab
Comparing gadget prices or checking multiple news articles usually means closing your current page just to open another one. On Huawei phones the Browser app lets you keep the page you are on running in the background while you open a fresh tab for research. Many users overlook this because the tab controls sit in a spot that is easy to miss on first use.
Change Default Search Engine
If every search on your Huawei phone routes through Google, you might want to switch to Bing or Qwant instead. The Browser app ships with Google as the default provider, and there is no shortcut for this on the home screen or in the quick settings. Many users assume the engine is locked and give up before finding the actual option.
Adjust Colour Mode & Temperature
If your Huawei display looks too cold and bluish, or colours seem flat and washed out, the colour mode and temperature are likely stuck on a default that does not suit you. Huawei lets you switch between a neutral 'Normal' look and a punchier 'Vivid' mode, and you can fine-tune the warmth of the screen yourself instead of relying on the factory setting.
