Set Default Launcher App
If a new launcher from the Play Store keeps getting ignored and your phone reopens the stock home screen after every reboot, the default app assignment was never updated. Tapping the Home button can also snap you back to the original layout instead of the launcher you just installed. This happens because Realme UI keeps its own launcher set as default until you point the system to a different one.
Personal Hotspot: Sharing Your Mobile Data
Personal Hotspot turns your Realme phone into a Wi-Fi access point, letting laptops, tablets or other phones use your mobile data connection. It matters whenever a fixed Wi-Fi network is missing, unreliable or restricted, and you need a quick, secure way to get another device online. Realme UI gives you control over who connects, how much data they use, and how long the hotspot stays active.
App Cache and Storage Data
Every app on your Realme phone stores temporary cache files and permanent data to work faster and remember your settings. Knowing the difference helps you free up storage without losing logins, saved games, or app preferences. This overview explains what each storage type does and when clearing it actually helps.
Allow or Deny Messages in Do Not Disturb
Do Not Disturb on your Realme phone mutes calls, but messages can still buzz through with sound and vibration if no exception is set for them. Or the opposite happens: texts from people you actually want to hear from get silenced along with everything else. The setting that controls this sits separately from the call exceptions, which is why many people miss it.
Create a Folder on the Home Screen
When your home screen fills up with icons on your Realme phone, related apps get scattered and take longer to find, whether the app drawer is turned on or off. Grouping apps into a folder keeps the layout readable without deleting or hiding anything. Realme UI lets you build a folder directly on the home screen with a simple drag gesture, no extra menu required.
Turn OSIE Visual Effect On or Off
If photos and videos look oversaturated or artificially sharpened in supported apps on your Realme phone, the OSIE visual effect is likely active. The engine boosts colors and textures automatically, which can also increase power draw during playback. Turning it off returns images to their natural look and can help save battery.
Set up a Proxy Server for Wi-Fi
Some corporate networks or content filters only let you online through a proxy, and without the right host and port your realme phone just spins on 'Connecting'. Realme UI lets you attach proxy settings to a single Wi-Fi network so every app routes traffic through that server instead of directly. Missing or wrong proxy data is the usual reason browsing fails even though Wi-Fi shows as connected.
Set Up Fingerprint Unlock
Unlocking your Realme phone with a PIN or pattern every time gets tedious fast, especially when you only want to glance at the screen. Fingerprint Unlock lets the sensor recognize you instantly, but it only works once a fingerprint is actually registered under Password & biometrics. Without that step, the sensor stays inactive and Realme UI keeps asking for your backup unlock method.
Set Up App Lock for Individual Apps
Anyone who picks up your unlocked Realme phone can open banking apps, messengers, or your gallery without a second check. App lock closes that gap by asking for an extra password before a chosen app opens, but the option only appears once a privacy password exists on the device. Without that password set first, the switch for locking individual apps stays inactive.
Turn On/Off Auto-Switch to Receiver
If you switch a call to speaker on your Realme phone, you normally have to tap the speaker icon again before holding the phone back to your ear. With Auto-switch to receiver enabled, the proximity sensor detects when you lift the phone and moves the audio back to the earpiece by itself. This guide shows where the toggle sits and what stops it from working reliably.
Delete a User Account
If a family member or friend no longer uses your Realme phone but their profile still takes up storage or shows outdated apps and data, removing that user account fixes it. Deleting a profile wipes every setting, app, and file tied to it at once, so it is worth double-checking before you confirm. Only the phone's administrator can do this, and the guest profile cannot be removed the same way.
Optimize Battery Usage for Background Apps
If WhatsApp or other messaging apps deliver notifications late or not at all on your Realme phone, background battery optimization is usually the reason. Realme UI can throttle or kill background processes per app to save power, which cuts off syncing before new messages arrive. Getting this setting wrong on the wrong app either drains the battery faster or breaks notifications and background sync.
Power + Volume Down Screenshot Shortcut
If pressing the power button and the volume down button at the same time does nothing on your Realme phone, the screenshot shortcut for this combo is switched off. Some people go the other way and want to turn it off completely, because the phone keeps grabbing screenshots by accident while they adjust the volume. This on/off switch sits separately from the screenshot gestures and is easy to miss in the settings.
Show or Hide Camera Grid Lines
If the camera viewfinder on your Realme phone shows no horizon guide, framing landscapes or straight architecture shots gets harder. Photo and video mode each have their own grid toggle, so one can stay on while the other stays off. Checking the right setting fixes this in seconds.
Set Default Browser App
Tapping a link in a message or email opens a browser you never use, while your preferred app like Chrome, Firefox or Opera stays untouched. On Realme phones this happens because the system, not the app you just installed, decides which browser handles every link.
Allow Calls and SMS for a Secondary User
A newly created user on your Realme phone can open apps but cannot dial numbers or send text messages. That is expected behavior, not a SIM or network issue, since Realme UI blocks calls and SMS for every new user account by default. Each account needs this permission switched on separately before it can use the phone app.
Contact Suggestions in the Keyboard
When you fill out a form or type a message on your Realme phone, the keyboard sometimes offers a contact's name, phone number or email address as a suggestion instead of a regular word. If that shortcut never appears, the Suggest Contacts option inside Gboard is probably switched off, leaving you to type every detail manually.
Turn Double-tap to Wake Screen On or Off
If double-tapping the black screen on your Realme phone does nothing, the gesture might be switched off in the display settings. Some users also find the opposite problem: the screen wakes up by accident inside a pocket or bag, draining battery and triggering random touches. Both issues come down to the same Home screen & Lock screen setting.
Turn On/Off Super Power Saving Mode
When your realme phone drops to a critical battery level, background apps, sync and animations keep draining power even while the screen is off. Super power saving mode stops that by shutting down non-essential background processes and switching every screen to dark mode. The trade-off is that most apps outside a short essential list stop working until you turn the mode off again.
Turn On/Off Emergency Alerts
If your Realme phone keeps buzzing with alerts you never opted into, or if severe weather warnings suddenly stop showing up, the Wireless emergency alerts settings control which categories reach you. Extreme threats, Severe threats, and AMBER-style notices each have their own switch, tone, and vibration setting tucked inside Security. Missing one toggle is usually the reason alerts feel either too loud or completely silent.
Set Up Screen Lock with Pattern, PIN or Password
If your realme phone still opens with a simple swipe, anyone who picks it up gets full access to your apps, photos and messages. Realme UI offers four lock types - Pattern, a 4-digit PIN, a longer 4-16 digit password, or an alphanumeric password - each with a different trade-off between speed and protection. Picking the wrong one often means either unlocking too slowly or leaving the device too easy to guess.
Change Home Screen Transition Effect
Swiping between home screens on your Realme phone always plays the same plain slide animation, and there is no obvious setting for it in the general Display menu. The option to change this wipe effect actually lives inside the Home screen settings, which is why most people never come across it by accident.
Change Navigation Button Order
If you use button navigation on your Realme phone, Back, Home, and Recent apps stay in a fixed order until you change it yourself. A layout that does not match your grip can make one-handed use awkward and lead to mis-taps. Realme UI lets you flip between two button arrangements to fit how you actually hold and use your phone.
Privacy Password: A Separate Lock for Apps and Hidden Files
A Privacy Password on Realme phones works independently from your screen lock and shields specific apps, hidden photos, and private folders from anyone who unlocks the device itself. It becomes relevant the moment you hand your phone to someone else but still want certain content off limits. Setting it up also means dealing with recovery options in case you ever forget it.
