Galaxy S26/S25 Ultra Problems Solved! Step-by-Step Fix Guide

Part 1. Samsung Galaxy S25 Ultra Battery Draining Fast

Fast battery drain is one of the most common Samsung S25 Ultra issues. It can happen for a few reasons, such as high screen brightness, smooth refresh rate, and intensive background apps.

Solutions 1. Change Display Settings

The display is one of the main sources of battery drain. High brightness and refresh rates use more power, so adjusting these settings can noticeably extend battery life.

• Open Settings
• Go to Display
• Lower Brightness / enable Adaptive brightness
• Reduce Screen Timeout and turn off Always-On Display
• Reduce Refresh Rate if needed

Solutions 2. Disable Power-Hungry Apps

Some apps run in the background and drain the battery faster than expected. Checking battery usage helps you identify these apps and reduce their background activity.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and then Battery usage
• Find the top draining apps and limit notifications/background use

Solutions 3. Put Battery-Hungry Apps to Sleep

Instead of uninstalling apps, you can put rarely used or power-hungry apps to sleep. This prevents them from running in the background while keeping them available when needed.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and then Background Usage Limits
• Add Apps to Sleeping or Deep Sleeping

Solutions 4. Stop GPS From Running All Day

Location services can drain battery quickly when running all day. Limiting GPS access to only necessary apps or using it only while apps are open helps reduce unnecessary power consumption.

• Open Settings
• Go to Location
• Turn off location for apps that don’t need it
• Set to “While Using” for apps that are location sensitive, such as the Weather app.

Solutions 5. Enable Samsung Battery AI

Samsung Battery AI learns your usage patterns and optimizes power consumption automatically. Enabling this feature helps improve battery efficiency without requiring manual adjustments.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and then More Battery Settings
• Toggle Adaptive Battery ON.

Solutions 6. Enable Power Saving or Battery Saver Mode

Power Saving mode reduces background activity and system performance to extend battery life. It is especially useful when your battery is low or you need longer usage time.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and toggle on Power Saving

Part 2. S26 Ultra Fingerprint Sensor Not Working? 8 Fixes

• Proceed to add new fingerprints
• Scan slowly and use different angles

Fixes 4. Use Samsung-Approved Screen Protectors

Cheap or thick protectors often cause Samsung S25 Ultra issues with fingerprint reading. Always use a Samsung-recommended screen protector.

Part 3. Samsung Galaxy S26 Ultra Overheating

Among many reasons, Samsung phones usually get hot because of heavy gaming, fast charging, high screen brightness, 5G usage, or too many apps running in the background. In fact, it is one of the common Samsung S25 Ultra issues, and S26 Ultra will be no exception.

Below, we look at how to cool down your Galaxy phone quickly and efficiently.

Solutions 1. Don’t Use Your Phone While Charging

Using your phone while charging increases heat buildup because the device is both charging and processing tasks at the same time. This extra load can worsen overheating issues and slow down charging efficiency.

Solutions 2. Reduce Display Heat

The display generates significant heat during prolonged use. Lowering brightness and reducing screen timeout helps minimize heat buildup and keeps your phone cooler during daily use or gaming.

• Open Settings
• Go to Display
• Lower brightness
• Reduce screen timeout.

Solutions 3. Activate Samsung Game Booster Cooling

During a game, open the Game Booster / Performance monitor. Turn on auto performance management to help control temperature. Samsung’s Game Booster includes built-in performance and temperature controls. Enabling automatic performance management helps regulate heat during gaming sessions without manual adjustments.

Solutions 4. Use Power Saving When Gaming

Power Saving mode reduces system load and heat generation. Although gaming performance may be slightly affected, it helps prevent overheating during extended gameplay.

• Open Settings
• Go to Battery
• Enable Power Saving
• Although game performance will be impacted, there will be no overheating

Solutions 5. Stop Background Apps

Apps running in the background can increase CPU usage and heat. Closing unused apps or limiting background activity helps reduce unnecessary processing and keeps temperatures under control.

• Open Settings
• Go to Battery and Device Care
• Close unused apps/limit background usage.

Solutions 6. Check What’s Overheating It

Identifying the specific app causing overheating allows targeted fixes. Checking battery usage helps you find problematic apps and restrict them to prevent excessive heat and battery drain.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and then Battery usage
• Find the app causing overheating and battery drainage
• Restrict it

Part 4. Samsung S26 Ultra Camera Shaking

Camera shaking on the Samsung S26 Ultra camera can be scary, but it’s often fixable. It can happen due to OIS, camera app glitch, and dirty lens, among other factors.

Fixes 1. Clean the Camera Lens

Use a soft microfiber cloth and wipe the lens gently. Remove all dust, fingerprints, and smudges that can confuse focus and stabilization.

Fixes 2. Restart Your Phone

Restarting your phone clears temporary system glitches that may cause camera shaking or unstable performance.

• Hold the Power button
• Tap Restart (This clears temporary bugs)

Fixes 3. Reset Camera Settings

Incorrect camera settings can lead to shaking issues. Resetting them restores default configurations and often resolves the problem.

• Open the Camera app
• Tap the Settings icon
• Choose Reset settings

Fixes 4. Clean Up Photo Clutter

Delete large videos and duplicate photos or move them to a cloud or external storage to keep the camera running smoothly. Too many photos and videos can slow down the camera app. Removing clutter helps the camera run more smoothly.

Fixes 5. Disable Stabilization Features

In some cases, stabilization features may malfunction. Turning them off can help reduce unexpected camera shaking.

• Open the Camera app
• Tap the Settings icon
• Turn off Video Stabilization

Fixes 6. Turn on Safe Mode

Safe Mode helps determine whether third-party apps are causing camera issues by running the system with default settings only.

• Power off your device
• Boot it again
• When the logo appears, hold the Volume Down button until the Safe mode initiates.
• If the shaking stops, a third-party app is causing the Samsung S26 Ultra camera shaking issue

Part 5. Samsung S26 Ultra Camera Focus Issue

If you’re asking, “Why is my Samsung S26 Ultra camera blurry?”, you’re not alone. Here’s why your photos look blurry and how you can fix them.

Why Is My Samsung S25 Ultra Camera Blurry?

• Autofocus Problems : The camera keeps “hunting” and cannot lock focus, especially on shiny objects, moving subjects, or very close shots.
• Dirty or Smudged Lens : Smudgy fingerprints and dust particles confuse the camera's autofocus and make photos look hazy.
• Low Light / Night Shots : During low-light or night shots, the camera uses a slower shutter speed, so your hand movement causes blur.
• Wrong Camera Settings : Wrong settings often lead to unclear photos due to a mismatch in camera settings, user expectations, and how the photo is taken.

How to Fix Blurry Photos on S26/S25 Ultra

If your photos look blurry, the following solutions address common focus and software issues. Try these steps in order to improve image sharpness and restore normal camera performance.

Solutions 1. Restart the Phone

• Tap and hold the Power button
• Select Restart

Solutions 2. Use Manual Focus

• Open the Camera app
• Switch to Pro/Manual mode
• Tap MF (Manual Focus)
• Move the focus slider until your subject looks sharp

Solutions 3. Reset Camera Settings

• Open the Camera app
• Tap the Settings icon
• Select Reset settings

Solutions 4. Boot into Safe Mode

• Power off your device
• Power on again
• When the Samsung logo appears, hold the Volume Down button
• Test the camera in Safe Mode
• If focus works in Safe Mode, a third-party app is causing the issue

Part 6. S26 Ultra-Fast Charging Suddenly Stops Working

Fast charging suddenly stopping is one of the newer Samsung S25 Ultra issues. Since the S26 Ultra launch is closing in, users worry it may also impact the new devices.

Fixes 1. Check Fast Charging Setting

Sometimes fast charging is simply turned off in settings, which makes charging feel much slower than expected. Enabling Fast Charging or Super Fast Charging ensures your Galaxy can use the maximum supported charging speed.

• Open Settings
• Go to Battery and Device Care
• Select Battery and then More Battery Settings
• Enable Fast charging / Super Fast Charging

Fixes 2. Inspect Charger & Cable

Use a Samsung-authorised adapter and a good USB-C cable. Bad cables are often the cause of Samsung S25 Ultra problems (S26 Ultra too), like slow/stop charging.

Fixes 3. Check USB-C Port

If your phone shows a water drop icon, let the port dry fully. Charging can stop as a safety feature.

• Turn off the phone
• Use a flashlight
• Gently remove lint with a soft brush (no metal tools)

Fixes 4. Cool Down the Phone

When the phone gets too hot, charging can slow down or pause to protect the battery. Let it cool at room temperature, remove the case, and avoid heavy use while charging for more stable performance.

Fixes 5. Disable Power Saving

Power Saving mode may limit charging speed and performance. Turning it off can help charging return to normal.

• Open Settings
• Go to Battery and Device Care
• Tap Battery and select Power Saving
• Turn Off Power Saving

Fixes 6. Factory Reset Samsung Galaxy

If none of the fixes work, the issue may be caused by deeper software corruption. A factory reset can remove system bugs and restore default settings. Back up your data first, then reset only as a last resort.

• Open the Settings app
• Go to General Management
• Select Reset, and then the Factory Data Reset

Part 7. Samsung S25 Ultra Not Connecting to Wi-Fi

Wi-Fi problems are common Samsung S25 Ultra issues, and they’ll also likely happen on the S26 Ultra.

Most of the time, it’s a small glitch in the phone’s Wi-Fi settings, a router problem, or a VPN/security app blocking the connection.

Solutions 1. Toggle Wi-Fi

Toggling Wi-Fi refreshes the wireless connection and often fixes minor network glitches instantly.

• Swipe down to open Quick Settings
• Tap to turn Wi-Fi off
• Wait 10 seconds
• Tap on

Solutions 2. Reconnect to Network

Forgetting and reconnecting to the network helps clear saved connection errors or incorrect settings.

• Open Settings and go to Connections
• Select Wi-Fi and tap your Wi-Fi name
• Forget it
• Select it again and enter the password carefully

Solutions 3. Restart Router

Restarting the router refreshes the network and resolves many common Wi-Fi stability issues.

• Unplug your router power cable
• Wait 30 seconds
• Plug it back in and try again

Solutions 4. Disable VPN & Security Apps

VPNs often block and break connections.

• Open Settings and go to Connections
• Select More Connection Settings and then VPN
• Pause any security/firewall apps and test Wi-Fi again

Solutions 5. Reset Network Settings

Resetting network settings clears corrupted Wi-Fi and Bluetooth configurations that may be causing persistent connection problems.

• Open the Settings app.
• Go to General Management and then Reset
• Choose Reset Network Settings (this removes saved Wi-Fi/Bluetooth).

Part 8. S25 Ultra Animation Speed So Slow

Slow and laggy animations are one of the annoying Samsung S25 Ultra issues, especially after installing many apps or widgets. If your S25 Ultra feels laggy, these are the main reasons (these apply to S26 Ultra too):

Why Is Samsung S25 Ultra Animation Speed Slow?

Slow animations are usually caused by system load, disabled smoothness settings, or limited available storage.

• Too Many Background Apps : Many apps running together use RAM and slow system animations.
• Motion Smoothness / Animation Settings : If 120Hz is off, scrolling and app opening will feel slow.
• One UI Features & Widgets : Too many widgets, live wallpapers, and visual effects can cause S25 Ultra issues like stutter.
• Storage Nearly Full : When storage is almost full, the phone struggles to load animations smoothly.

How to Make Animations Faster on S25 Ultra

The following fixes help improve animation smoothness by optimizing display settings, system performance, and storage usage.

Fixes 1. Enable 120Hz Motion Smoothness

• Open the Settings app
• Go to Display
• Tap Motion smoothness
• Select Adaptive (120Hz) and apply

Fixes 2. Close Background Apps

• Open the Settings app
• Go to Battery and Device Care
• Tap Memory and then Clean Now (or close unused apps).

Fixes 3. Free Up Storage

• Open the Settings app
• Go to Battery and Device Care
• Select Storage
• Delete large videos, unused apps, and junk files

Fixes 4. Disable Power Saving / Battery Protection

• Open the Settings app
• Go to Battery and Device Care
• Tap Battery and select Power Saving
• Turn Off Power Saving

Fixes 5. Reduce or Remove Widgets & Live Wallpapers

Widgets and live wallpapers constantly refresh in the background and consume system resources. Removing unused widgets and switching to a static wallpaper can reduce system load, improve animation smoothness, and help your phone feel faster overall.
