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
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 Removing the outdated entry clears that conflict for good.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.

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.

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
Notifications & Focus

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
Apps & Installation

App Installations and Permissions on Android

Installing an app on your Realme phone is more than tapping a download button. This area covers where apps come from, which permissions they ask for, and how Realme UI keeps unwanted installs in check. Getting these settings right saves storage and keeps your phone free of software you never approved.

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.

Open
Language & Input

Text Correction and Keyboard Input Settings

Realme UI includes a set of typing tools that catch mistakes, predict words, and adapt to the languages you use most. This area covers autocorrect, predictive text, spell check, and personal dictionaries, and explains how each one shapes what you see while typing. Understanding these settings helps you fix annoying auto-changes without losing the convenience they were built for.

Eye Comfort and Blue Light Protection

Eye Comfort is the screen setting on Realme phones that reduces blue light and adjusts color tone to ease strain during long sessions or evening use. It works alongside brightness and dark mode to make the display gentler on your eyes without turning the screen unusably yellow. This overview explains what the feature actually changes and when it makes sense to rely on it.

Open
Display & Home Screen

Turn On/Off Dark Mode

If your realme phone still shows bright white menus at night or you want the home screen and apps to switch to a darker layout, the theme setting is likely still on Light. Dark mode changes the look of the system, the home screen and most compatible apps in one step, and it can also help reduce battery drain on screens with an OLED panel.

Open
Notifications & Focus

Turn Touch Vibration On or Off

Every tap on a menu, button or option on your Realme phone triggers a short vibration by default. During calls, gaming or one-handed typing, that constant buzz starts to feel like unwanted haptic noise. It also fires on the on-screen navigation buttons, not just inside apps.

Auto Brighten Screen for Face Recognition

If face unlock keeps failing in dim rooms or at night, your Realme phone might not be brightening the display enough to scan your face properly. The Auto brighten screen for face recognition feature controls this automatic boost, and when it is off or set the wrong way, unlocking in low light becomes unreliable.

Security & Privacy

Screen-off Unlock: Light or Firm Touch

If your Realme phone unlocks the moment you rest a finger on the power button, or refuses to unlock until you press it firmly, the screen-off unlock sensitivity is set the wrong way for how you hold your phone. This setting controls whether a light touch or a firm press on the fingerprint sensor in the power button wakes and unlocks the device.

Security & Privacy

Change Privacy Password Security Question

If you set up the privacy password on your Realme phone but can no longer remember the security question tied to it, you could get locked out of hidden apps and files. The security question acts as the backup recovery method for that password, so an outdated or forgotten answer becomes a real problem the moment you need it. Realme lets you update this question directly from the security settings without wiping your hidden data.

Security & Privacy

Rename a Fingerprint

On a Realme phone every fingerprint you enroll gets a generic label like Finger 1 or Finger 2 by default. Once you have three or four prints stored, that numbering makes it hard to remember which entry belongs to which finger or family member. Giving each print a proper name keeps your fingerprint list readable at a glance.

Smart Sidebar on Realme Phones

Smart Sidebar is a floating panel that gives you one-tap access to your favorite apps and tools without leaving what you are doing. It sits at the edge of the screen and pulls out over almost any app, including games. Understanding how it works helps you multitask faster and skip unnecessary app switching.

Open
Display & Home Screen

Show or Hide Status Bar Icons

A status bar packed with icons for Bluetooth, alarm, NFC, and mobile data can bury the one piece of information you actually need. On many Realme phones several of these icons stay switched on by default even if you barely use the connection behind them. The status icons menu lets you turn each icon on or off on its own instead of living with a crowded display.

Battery & Power

Optimize Battery Consumption

If your Realme phone drains faster than expected and you cannot pinpoint which app or setting is responsible, checking each menu manually takes too long. Realme UI can scan system and app behavior on its own and return a list of tailored suggestions to extend battery life. You choose which suggestions to apply, so background tasks you rely on stay untouched.

Open
Calls & Messages

Show or Hide Caller ID

Outgoing calls from your Realme phone sometimes show your number when you wanted privacy, or the other side sees 'Unknown caller' when you actually wanted to be reachable by name. This behavior depends on a caller ID option tied to your SIM card rather than one global switch. Dual-SIM users often notice each card acts differently until both are configured separately.

Display & Home Screen

Rename a Folder

New folders on your Realme home screen get generic names like 'Social Networks' or 'Lifestyle', assigned automatically based on the apps you drop inside them. If you sort apps by your own logic - projects, moods, or daily routines - these auto-generated labels stop making sense fast. Renaming lets you turn any folder into something that actually matches how you use your phone.
