Display & Home Screen

Switch Between Navigation Buttons and Gesture Controls

If the three-button navigation bar keeps taking up screen space on your Realme phone, or you switched to gesture controls and now miss having visible Back and Recent buttons, the setting that controls this sits in Navigation. Realme UI lets you swap between virtual buttons and swipe gestures at any time, and each mode changes how you go back, return home, and view recent apps.

Open
System & Settings

Turn On Developer Options

Hidden tools like USB debugging, force GPU rendering, or extended app logging stay out of reach until Developer options shows up in your Realme Settings menu. On Realme phones running Realme UI, this menu is hidden by default and only appears after a specific tap sequence on the build number. Without it, app testing, ADB connections, and some sync-related tweaks stay locked away.

Enable or Disable On-body Detection

If your Realme phone keeps unlocking itself while it sits in your pocket or you are just holding it, Smart Lock's On-body detection is the reason. This feature relies on the motion sensor to keep the lock screen inactive whenever the phone is being carried, regardless of who is carrying it. That means it never checks your identity, so anyone who takes the phone from your hand gets in without a PIN or password.

System & Settings

Wake Google Assistant with the Power Button

Holding the Power button on your Realme phone should launch Google Assistant almost instantly, but if the shortcut stays off in the background, nothing happens no matter how long you press. Some users also worry that this gesture interferes with the regular power off menu. The two actions actually rely on different hold times, and mixing them up is usually what causes the confusion.

Open
Notifications & Focus

Turn On/Off Notification Badges

If an app icon keeps showing a dot or number even after you have read every message, or you would rather see no badge at all, the badge style is set per app on Realme phones. You can choose between a number, a dot, both, or nothing, but most people never touch this setting and end up stuck with whatever was set by default.

Open
Notifications & Focus

Show or Hide Notification Icons in the Status Bar

When app icons pile up in the status bar of your Realme phone, it gets hard to tell which app actually needs your attention. If you would rather see a simple number of unread notifications, or nothing at all, the notification display mode in Realme UI is set to the wrong option. Switching between icon, count, and hidden mode fixes both problems.

Open
Battery & Power

Auto-Disable Power Saving Mode

If Power saving mode switches off on its own once your Realme phone hits around 60% charge, a background battery rule is doing the work — not a bug. That behavior can throw off performance settings you rely on, especially if you charge in short bursts throughout the day.

Open
Security & Privacy

Turn On/Off Emergency SOS Quick Access

Pressing the Power button five times by accident can trigger an emergency call you never meant to make. On Realme phones this happens because Emergency call quick access is turned on by default and dials a preset regional emergency number. If you keep hitting this shortcut without wanting to, the setting needs to be switched off - or checked if it silently stopped working when you actually need it.

Open
Display & Home Screen

Show or Hide the World Clock Widget on the Home Screen

Added cities in the World Clock app do not automatically show up on the Realme home screen. Without the matching widget switched on, the status bar still only shows your local time, even though several time zones are already saved. Once visible, the widget behaves like any other home screen element and can be moved or resized freely.

Open
Security & Privacy

Turn Off App Lock

Once App lock is active on your Realme phone, every protected app asks for your privacy password before it opens, even for quick checks you no longer want locked. Removing the feature only works with the correct privacy password on hand. If you plan to reset or sell the phone, an active App lock can also get in the way unless you switch it off first.

Resetting a Realme Phone: Options Explained

A reset can fix a frozen phone, clear a stuck setting, or wipe your device before you sell it — but not every reset does the same thing. This overview explains the difference between restarting, resetting settings, and erasing all data, so you pick the right one for your situation.

Open
Notifications & Focus

Do Not Disturb Notification Exceptions

When Do Not Disturb is active on your Realme phone, alerts can vanish from the status bar, lock screen, and notification drawer without any warning. If you still want banners, badges, or lock screen previews for certain apps to get through, the Allowed notifications settings decide what stays visible. Getting this wrong means missing time-sensitive alerts or being interrupted anyway.

Open
Calls & Messages

Set Up Fixed Dialing Numbers (FDN)

If your Realme phone still connects to numbers you never approved, Fixed Dialing Numbers (FDN) is likely still switched off. FDN limits outgoing calls, except emergency numbers, to a list you control, but the feature only activates after you enter your SIM PIN2. Without that PIN2 on hand, the option in your calling settings stays greyed out.

Open
Security & Privacy

Set Up a Privacy Password

If App Lock or the Private Safe on your Realme phone suddenly asks for a password you never created, that is the privacy password, and it works independently from your screen lock. Both can use a PIN, pattern or password, which makes them easy to mix up. Until you set the privacy password up, you cannot lock individual apps or open the private storage area.

Open
Notifications & Focus

Sound & Notification Controls

Realme UI splits ringtone, media, alarm and notification sounds into separate controls, so a call can stay loud while music stays quiet. This hub explains how those volume sliders, notification channels and Focus modes work together, and where each setting actually changes phone behavior.

Open
Display & Home Screen

Add a Widget to the Home Screen

If your home screen only shows app icons, you keep opening apps just to check simple things like the weather, battery level or your next calendar entry. Realme UI hides the entire widget picker behind a long-press gesture that many people never discover on their own. Without adding a widget, that information stays one tap further away than it needs to be.

Open
Network & Connectivity

Delete Access Point Names (APNs)

Old or wrongly configured APN entries on a Realme phone can block mobile data even after you fix the actual settings, since the phone might still be pointed at a broken profile. This gets especially annoying after a SIM or provider swap, when the previous carrier profile lingers in the list and confuses the new connection. Removing the outdated entry clears that conflict for good.

Open
Apps & Installation

Turn On/Off Background Data Usage of Apps

If notifications from an app only show up after you open it, background data for that app is probably switched off. Realme UI blocks internet access for inactive apps in this state, so messages, mail or chat updates never reach you in real time. The setting sits inside the individual app entry, not in a general notification menu.

Open
Notifications & Focus

Do Not Disturb and Notification Focus

Do Not Disturb mutes calls, alerts and vibrations while you work, sleep or drive, without cutting you off completely from the people who matter. On Realme phones you decide which contacts, apps or alarm types still get through while everything else stays quiet. Scheduled sessions can switch the mode on and off automatically, so you never have to remember to flip it yourself.

Open
Photo, Video & Media

Allow or Deny Picture-in-Picture per App

When a YouTube or Netflix video suddenly loses its floating window and jumps back to full screen the moment you open another app, Picture-in-Picture is disabled for that specific app on your Realme phone. Realme UI controls this permission separately for every app, so enabling it once for YouTube does not activate it for Netflix or any other media app. Without this permission, switching apps pauses or closes the video instead of shrinking it into a movable window.

Open
Display & Home Screen

Screen Resolution Settings

Screen resolution controls how sharp your display looks and how much battery it draws while doing it. On Realme phones you can switch between fixed resolution modes or let the system adjust automatically depending on what you are doing. Knowing how this setting works helps you balance clarity against battery life instead of guessing.

Open
Security & Privacy

Unlock Private Safe with Fingerprint

Typing a password or PIN every time you check the Private Safe on your Realme phone gets tedious fast. The safe hides files and apps behind its own lock screen, separate from the phone unlock, and by default only accepts that password, pattern or PIN. A quick fingerprint shortcut can replace most of those manual entries.

Open

Turn Keyboard Vibration On or Off

Every tap on the realme keyboard can trigger a short buzz to confirm the keypress, but that constant vibration gets annoying fast during calls, meetings, or late-night typing. If Gboard keeps buzzing after every letter or stays silent when you actually want feedback, the haptic setting is likely set the wrong way for your habits.

Open
Network & Connectivity

Turn On/Off SIM Card Lock

If your Realme phone asks for a PIN every time you restart it, SIM card lock is active in the background. Enter that PIN wrong three times in a row and the SIM locks itself completely, cutting off calls, texts and mobile data until you unlock it with a PUK. Turning the lock off removes the restart prompt, but it also removes the protection against someone else using your SIM.
