Change SIM PIN
A new SIM card usually ships with a default PIN chosen by your carrier, and that code is rarely one you would pick yourself. On Realme phones this PIN lives in the Security settings, completely separate from your screen lock or device password. Keeping the default in place makes it easier for anyone who gets hold of your SIM to guess it.
Volume & Sound Controls
Realme phones split sound into several independent channels: media, ringtone, notification, alarm and call volume. This area explains how those channels interact with each other and with silent, vibrate and focus modes, so you stop guessing why one slider changes and another stays the same.
Reset Advertising ID
If ads on your Realme phone still feel oddly specific even after you cleared your browser history, the tracking is happening through a device-level advertising ID, not your browser. This identifier links your app activity and search behavior across services until it gets reset. Resetting it breaks that link and starts a fresh, anonymous tracking profile.
Show or Hide App Suggestions in the App Drawer
Every time you open the app drawer on your Realme phone, a row of suggested apps shows up above your full app list, picked based on what you have opened recently. If you find that suggestion bar distracting, or you just do not want Realme UI displaying your last-used apps at the top, that behavior comes from a single toggle you may not have noticed yet.
Allow Repeated Calls Through Do Not Disturb
When Do Not Disturb is active on a Realme phone, even urgent second calls from the same number can get silenced along with everything else. This makes it hard to tell a routine call apart from someone trying to reach you again because of an emergency. Realme UI has a dedicated exception for this, but it is easy to miss if you only check the contact-based Do Not Disturb settings.
Turn On/Off Call Barring
If unwanted international calls keep coming through or you need to block outgoing calls on a shared or work SIM, call barring lets you restrict specific call types on your Realme phone. On Dual SIM devices the restriction only applies to the SIM you configure, not both cards at once. Getting the wrong option turned on can also block calls you actually need, such as roaming while traveling.
Turn On/Off Optimized Night Charging
If your phone sits on the charger all night at full charge, the battery wears out faster than it should. Optimized night charging on Realme phones learns your daily routine and slows the final part of the charge so the battery is not held at 100 percent for hours. When the feature is off or your charging habits are irregular, the phone reaches full charge quickly and just stays there until you unplug it.
Autospace After Punctuation: Enable or Disable
If your texts need a space right after a period, comma or question mark, Gboard on your Realme phone can add it automatically while you type WhatsApp messages or emails. The feature is still in beta and currently works only with the US English keyboard, so it may behave differently or stay hidden with other language settings.
Set Home Screen Wallpaper
If your Realme phone keeps showing the same default background or a live wallpaper you never picked, the Wallpapers menu inside Personalizations is where that setting lives. Static images, animated live wallpapers, and your own gallery photos all sit in one place, but picking the wrong option can leave a live wallpaper running in the background and draining battery. Knowing which category to pick first saves you from applying the wrong wallpaper twice.
Turn Airplane Mode On or Off
During a flight or in areas with strict wireless rules, your Realme phone still needs to cut cellular, Wi-Fi and Bluetooth signals at the same time. Switching off each radio separately is slow and easy to forget under time pressure. Airplane mode bundles all three, but many users are not sure where the toggle sits or what keeps working once it is on.
Turn Google Location History On or Off
If Google Maps Timeline shows blank days or never remembers the places you visited, Location History is probably switched off for your Google account. If you would rather stop your Realme phone from reporting your movements to Google at all, the same setting is what you need to check. Either way, the toggle sits inside your Google account settings, not in a separate Realme menu.
Move a Widget on the Home Screen
A widget lands in the wrong spot on the Realme home screen and clutters the icons around it. Since every widget has a fixed minimum size, a few pixels off can throw the whole layout out of balance. Repositioning it takes only a quick drag, but the exact gesture is not obvious on the first try.
Bluetooth Tethering Setup
If your laptop or tablet has no free USB port or you want to avoid draining your battery with a Wi-Fi hotspot, Bluetooth tethering shares your Realme phone's mobile data over an existing Bluetooth pairing. Speeds are lower than a Wi-Fi hotspot, but the connection uses noticeably less power. It only works with devices you have already paired over Bluetooth.
Deletion Sound: Turn On or Off
Every time you delete a text message or another item on your Realme phone, a short beep plays automatically. If that sound gets annoying or you cannot find where to switch it off, the option hides inside the general sound and haptics settings, not in a separate app.
Reset Camera Settings
If your Realme camera keeps producing washed-out photos, odd aspect ratios, or shaky video because of settings you tweaked earlier, going back through every option one by one wastes time. A full reset brings the camera app back to its factory configuration in seconds. Your existing photos and videos stay untouched.
Schedule Auto Power On/Off
Turning your Realme phone off every night and switching it on again the next morning is easy to forget, especially on weekends or while traveling. A missed power-off wastes battery and keeps notifications buzzing through the night. Realme UI lets you automate both actions so the phone starts up and shuts down on its own at fixed times.
Set Daily Data Limit
If your monthly data plan disappears within a few days, uncontrolled background usage on a single day is often the cause. Realme UI only tracks a monthly limit by default, so a heavy streaming or update day can go unnoticed until the bill or plan warning arrives. A daily limit gives you an earlier checkpoint before the monthly cap is even close.
Turn On Automatic Network Selection
If your Realme phone stopped switching networks automatically after a trip abroad or near a border region, chances are automatic network selection got switched off along the way. The phone then stays locked to whichever carrier it last connected to, even when a stronger signal from your home provider is available. This usually happens after a manual carrier search or a change made in roaming settings.
Set a Custom Ringtone from Your Own Audio Files
If the default ringtones on your Realme phone all sound the same, you can swap them for a song or audio file you already have on your device. On Dual SIM phones, you can also assign a separate tone to each SIM card, which helps you tell work calls apart from private ones just by the sound. This does not require any extra app.
Bluetooth Connections and Pairing
Bluetooth on your Realme phone lets you connect headphones, speakers, smartwatches, and other nearby devices without cables. It also handles quick file transfers and pairing with accessories that rely on a short-range wireless link. Knowing how the feature behaves helps you avoid dropped connections and battery drain.
Wi-Fi and Bluetooth Scanning for Location Accuracy
If your Realme phone still detects nearby Wi-Fi networks or Bluetooth devices after you switch both radios off, Wi-Fi and Bluetooth scanning is running in the background. This system function lets apps and location services use nearby networks and devices to sharpen your position, independent of the actual Wi-Fi or Bluetooth toggle. That extra accuracy comes with a trade-off in battery use and background access for apps you may not want scanning at all.
Enable Auto Click After Pointer Stop
Clicking a physical mouse button over and over on your Realme phone gets tiring fast, especially during long browsing or gaming sessions. Realme UI has a built-in option that fires a click automatically once the pointer stays still for a moment, so you never touch the mouse button again. The tricky part is finding the toggle and picking a dwell time that feels natural instead of triggering clicks by accident.
Set the Time Manually
If your Realme phone keeps snapping back to network time, entering a new value under Date & time does nothing. Realme UI pulls the clock from your carrier and region automatically, so any manual edit gets overwritten until that sync is turned off. This gets in the way when you have no active SIM, travel with data disabled, or just need a slightly different time for testing.
Change Sound Mode: Ringing, Vibrate or Silent
If your Realme phone stays stuck on Vibrate or Silent even after you tap a quick settings icon, the sound mode toggle in the status bar might not be syncing with your actual settings. This also shows up when calls go straight to Vibrate but notifications still play a tone, or the other way round. Knowing where the real Sound mode switch lives helps you fix mismatched behavior fast.
