Reset Network Settings
If WLAN keeps dropping, mobile data refuses to reconnect after switching networks, or Bluetooth pairings act up for no clear reason, a stuck network configuration is usually behind it. Resetting network settings wipes WLAN profiles, mobile data setups and Bluetooth pairings so the phone rebuilds them from scratch. On Dual SIM phones you also get to pick which SIM card the reset applies to.
Set Up Private DNS
On public or shared Wi-Fi, every domain your phone looks up travels as plain text, letting the network operator or anyone else on the connection see which sites you visit. Huawei phones ship with private DNS switched off by default, so this exposure continues until you activate an encrypted resolver. Turning it on requires the exact hostname of a DNS provider, not just an IP address.
Enable or Disable Wi-Fi Direct
Trying to send a photo or stream a video straight from your Huawei phone to a TV or Fire TV Stick only works if Wi-Fi Direct is active. When the toggle stays greyed out or nearby devices simply do not show up, the feature is usually switched off or hidden inside the Wi-Fi menu. Both devices also need to sit on the same Wi-Fi network before a direct transfer can start.
Enable or Disable Auto-Download Updates over WiFi
If your Huawei phone keeps grabbing software updates the moment it connects to WiFi, storage fills up before you even decide to install anything. On the other hand, if updates never seem to download on their own, this WiFi-only auto-download setting is usually the reason. Either way, the update only gets fetched, not installed, until you confirm it.
Enable or Disable Data Roaming
If your Huawei phone locks onto a foreign or unfamiliar network abroad, mobile data simply stops working until roaming is switched on. Once you activate it, the phone can use a foreign carrier's mobile network, and that access almost always comes with extra charges from your provider. Leaving roaming off protects you from surprise bills but also blocks data, calls, and messages on networks outside your home carrier.
Share Wi-Fi Password via QR Code
Typing out a long Wi-Fi password for guests or family members wastes time and often ends in typos. Huawei phones can turn the active connection into a scannable code instead of a string of characters. This works only for networks your device is already connected to.
USB Tethering: Enable or Disable
If your laptop shows no internet connection after you plug in your Huawei phone via USB, USB tethering is probably still switched off. Windows or macOS only picks up the shared connection once the toggle is active on the phone. Without it, the cable link stays a simple charging connection.
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.
Set Location Access for Apps
If an app keeps showing local ads, weather for the wrong city, or asks for your position every time you open it, its location permission is probably set too loose. EMUI lets you fine-tune this per app instead of using one global switch. Picking the right option also affects battery drain and how much data an app collects in the background.
Enable Simple Mode
If the home screen on a Huawei phone feels cluttered with too many icons, tiny text and confusing settings menus, Simple mode can fix that. It hides rarely used functions, enlarges icons and text, and reduces the interface to the essentials many users, especially seniors, actually need. The tricky part is finding the toggle, since it sits several menus deep and is easy to overlook.
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.
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.
Turn Google Location History On or Off
Even without opening a single Google app, your Huawei phone can still log where you go through Google Location History. Many people only discover this after checking their Google account and seeing a detailed timeline of past visits. This background tracking runs independently of Maps, Search, or any other Google service, and you can switch it off directly from the phone settings.
Enable or Disable 'Ask for Location' in Browser
If websites on your Huawei phone keep asking for your location every time you open them, or never ask at all, the browser's own permission setting is behind that behavior. This option sits inside the browser's site settings and works separately from the phone's general location toggle. Turning it off stops every website from requesting your position, while turning it on lets sites ask individually.
Limit Maximum Hotspot Connections
If your Huawei phone's mobile hotspot allows up to eight devices to connect at once, uninvited users or unnoticed background traffic can quietly eat into your mobile data plan. Lowering the connection cap gives you a clearer picture of who is actually using your hotspot and how much data each session pulls.
Restrict App Downloads to WiFi Only
If apps keep downloading or updating over your mobile connection and eating into your data plan, the Play Store app download preference is likely set to allow any network. This setting exists separately from your phone's general mobile data controls, so switching off mobile data elsewhere will not stop it. Adjusting the download preference inside the Play Store settings gives you direct control over when new apps and updates are pulled onto your Huawei phone.
Set Default SIM for Mobile Data
On a Dual SIM Huawei phone, mobile data can silently switch to the wrong SIM card, leading to unexpected charges or slower speeds. This happens when EMUI has never been told which SIM should handle mobile data by default. Without a fixed assignment, the phone may keep using whichever SIM was configured last.
Simple Contact View
If your contacts list is cluttered with profile pictures, company names and extra fields, scanning for a phone number takes longer than it should. Huawei devices include a simplified view that hides everything except the core details. This is especially useful if you mainly need quick access to numbers rather than full contact cards.
Connect to a Wi-Fi Network
If your Huawei phone shows no internet access or keeps dropping the connection, the Wi-Fi function itself might still be turned off. You need an active Wi-Fi connection before you can join a private network with a password or a public hotspot. Once Wi-Fi is switched on, your device lists every network within range so you can pick the right one.
Connect to Wi-Fi via WPS
Typing a long Wi-Fi password on a Huawei phone is easy to get wrong, especially with mixed-case or special characters. If your router has a WPS button, you can skip password entry entirely and pair the devices directly. This only works if WPS is enabled on the router and the phone is close enough to receive the signal.
Unpair a Bluetooth Device
Old Bluetooth connections pile up fast on a Huawei phone, especially after pairing with rental cars, speakers, or a friend's headphones you only used once. If a device you no longer use still shows up in your paired list, a broken or outdated pairing can also cause connection errors with a replacement device sharing the same name. Removing the pairing clears the stored connection completely, so the phone treats it as brand new next time.
Enable or Disable Wi-Fi+
If your Huawei phone keeps jumping onto mobile data even though you are sitting right next to your router, Wi-Fi+ is probably the reason. The feature watches your current Wi-Fi signal and switches connections on its own once it judges the network too weak. That can mean surprise mobile data usage or a phone that never stays on the Wi-Fi network you actually want.
Exit Simple Mode
If your Huawei home screen suddenly shows oversized icons and a stripped-down layout, Simple mode is active. This view limits app grouping and hides several settings that are normally visible on the standard home screen.
Configure Personal Hotspot Name and Password
If your personal hotspot still broadcasts the factory-set name and password, anyone nearby can recognize your phone and try to connect. A weak or default password also makes it easy for strangers to guess their way onto your data plan without asking first.
