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.
Show Battery Percentage
If your status bar only shows a plain battery icon with no numbers, you are left guessing how much charge your Huawei phone has left. EMUI hides the exact battery percentage by default and only displays a rough fill level. Turning this option on replaces the guesswork with a precise readout right in the status bar.
Enable or Disable Google Play Protect
If Google Play Protect keeps flagging a trusted app as harmful or blocks an install you actually want, the scanner is doing exactly what it's built for on your Huawei phone. It checks every app during and after download and rechecks apps from unknown sources on a schedule, then notifies you when it finds a risk. Switching it off stops the warnings, but it also removes that ongoing background scan from your device.
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.
Change SwiftKey Keyboard Theme
Stuck with the plain gray SwiftKey keyboard on your Huawei phone and want something with more color or a gradient background? The default look only changes the background and key colors, not the layout or key size, and the theme option is easy to miss inside the input settings.
Enable or Disable VoLTE Calls
If your calls sound muffled or take a few extra seconds to connect, your phone is likely still routing them over the 2G or 3G network instead of 4G. Huawei phones fall back to the older network for voice unless VoLTE (Voice over LTE) is switched on, which also affects battery drain during calls.
Set a Custom Timer Tone
On a Huawei phone, the timer in the Clock app always shows a small bell icon next to the countdown, but many people never open it to pick a different sound. The default timer tone plays until you swap it out from the built-in sound list. Once you choose a new tone, it applies to every timer you start afterward, not just the current one.
Call Forwarding Between SIM Cards
If one of your two SIM cards is switched off, out of coverage, or physically removed, callers trying that number just hit a busy tone or voicemail instead of reaching you on the other line. On dual-SIM Huawei phones, this happens because the two SIMs operate independently unless call forwarding between them is switched on. That's a problem if you rely on both numbers while traveling or when one card regularly drops signal.
Enable or Disable Performance Mode
If your Huawei phone drains battery faster or feels warmer than usual during heavy tasks, Performance mode might be switched on. This setting pushes the hardware to run at maximum output, which trades battery life and heat for extra speed. Turning it off restores the standard power balance.
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.
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.
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.
Send a File via Bluetooth
When a Bluetooth transfer just sits there or the receiving device never shows up in the list, it usually means the two phones were never paired first. Bluetooth sharing on Huawei phones runs through the system Share menu, so picking the wrong app or an unpaired device stops the transfer before it starts. This guide walks through sending a single photo, though the same steps work for videos and other files too.
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.
Enable or Disable Key Pop-ups
When you type on a Huawei phone, every letter you tap flashes briefly above the key before it appears in the message. In apps like WhatsApp or Messenger this preview can feel distracting, especially if you type fast or use a small screen. The behavior comes from a keyboard setting, not from the messaging app itself.
Set Default Launcher App
If your Huawei phone keeps opening the old home screen even after installing a new launcher, the system is still pointing to the previous default app. This happens because EMUI only switches the active launcher when you confirm the change in the app settings, not automatically after installation. Until that setting is updated, widgets, shortcuts and the app drawer stay tied to the launcher you had before.
Enable or Disable Google Voice Typing
Typing long messages on your Huawei phone takes forever when you have to tap out every word by hand. Google voice typing turns spoken words into text directly in the keyboard, but on many EMUI devices the option is buried and easy to miss or accidentally switch off. After a restart the feature can also seem to disappear until the phone is unlocked again.
Enable or Disable Autocorrect
When Huawei's keyboard swaps in the wrong word right as you hit send, the SwiftKey autocorrect feature is usually to blame. It rewrites words mid-sentence based on its suggestion bar, even when the word you typed was already correct. If this keeps producing typos or awkward phrasing in your messages, you can switch the feature off or back on in a few taps.
Merge Duplicate Contacts
Seeing the same person listed twice or three times in your phonebook usually means the contact was saved separately by your SIM, a synced account, and an app like WhatsApp. Each source keeps its own entry until you combine them, which also splits Calls and Messages history across multiple records. Huawei's built-in merge function is designed to clean this up without deleting any of the underlying data.
Change Lock Screen Wallpaper
Picking a new photo for your Huawei phone does not automatically change what shows on the lock screen. EMUI treats the home screen and the lock screen as two separate wallpaper slots, so after choosing an image you still get asked where it should actually be applied. Pick the wrong option in that prompt and the old lock screen image stays exactly as it was.
Enable or Disable Password Vault
If your Huawei phone stops offering to save login credentials or keeps autofilling old passwords you no longer want stored, the built-in Password Vault is either disabled or already holding data you need to manage. This local credential manager only works once a screen lock password is set, which is why activation sometimes fails silently. Knowing where the toggle lives helps you control exactly which logins get remembered on the device.
Voice Broadcast for Incoming Calls
If your Huawei phone is connected to a headset and voice broadcast is turned on, an incoming call plays the default ringtone instead of the custom tone you set for that contact. This happens because voice broadcast overrides individual ringtone assignments with a spoken caller announcement. The setting sits in the calling options and is easy to miss when you are troubleshooting missing custom ringtones.
Remain on Lock Screen After Face Recognition
After Face Recognition unlocks your Huawei phone, the screen sometimes stays on the lock screen and needs a swipe up before you reach the home screen. This happens because the Unlock device option is set to Slide to unlock instead of Direct unlock, or turned off entirely. The mismatch confuses users who expect the phone to open straight to the home screen right after a successful scan.
