Main issues reported after updating to Android 15
Android 15 has surprised many users with various issues affecting both high-end and more modest devices. While most of these problems are eventually resolved in subsequent updates, understanding them and knowing how to address them is crucial to preventing your experience with the system from turning into a nightmare. Google Pixel and Samsung Galaxy devices with One UI are among the most affected, although the bugs have also impacted devices from other brands and even recent models with their own custom interfaces.
Among the most frequent problems are:
- Connectivity failure (mobile data and Wi-Fi, Bluetooth and NFC issues).
- Errors in gesture navigation, especially on Google Pixel.
- Critical bugs in popular apps like Instagram, with crashes, shutdowns and malfunctions.
- Complications with new features such as the Private space.
- Serious issues during the OTA update, leading to the inoperability of some devices.
We now analyze each case in depth, outlining solutions, alternatives, and the steps to follow in each case.
Connectivity issues: mobile data, Wi-Fi, Bluetooth, and NFC
One of the most frequent problems after installing Android 15 is the complete or intermittent loss of mobile data and Wi-Fi connectivity . This issue primarily affects Samsung devices with One UI and other models that received the update in the first batches. Many users have reported that, despite having coverage and without having changed any settings, their phone cannot connect to the internet after the update, or experiences constant drops in the data signal.
Some of the most common symptoms are:
- Loss of connection to the mobile network or jumps between 4G and 5G for no apparent reason.
- Unable to connect to certain Wi-Fi networks or experience a drastic decrease in speed.
- Bluetooth stops working or constantly disconnects from external devices such as headphones, smartwatches, or car systems.
- NFC not responding when you try to use mobile payments or transfer data.
The most widespread solutions include:
- Reset network settings from Settings > System > Reset options > Reset Wi-Fi, mobile & BluetoothThis usually fixes minor issues but may require reconfiguring saved networks and paired devices.
- Recreate the APN access point (Settings > Mobile networks > Access Point Names) following your operator's instructions.
- Reboot the device after each configuration change.
- In extreme cases, perform a factory reset (after backup).
If the problem persists after these steps, it's key to keep your device up to date with future updates, as manufacturers typically release specific patches to address the most serious connectivity issues. Google and Samsung have prioritized these issues and typically release fixes within weeks of the initial reports.
Bugs with gesture navigation on Google Pixel and other devices
Gesture navigation is one of the most intuitive and popular ways to interact with modern Android, but after updating to Android 15, users of Google Pixel devices (especially the Pixel 8 and Pixel 8 Pro) have detected significant flaws in this feature. The most noticeable error is the lack of response to the back gesture when swiping from the right edge of the screen , while sometimes it only works from the left. This flaw is frustrating, as it prevents smooth and natural use, making it difficult to navigate between apps or system menus.
The most common causes of this problem are:
- Greater demands on the touch sensitivity, especially if you have a screen protector.
- Internal configuration issues in early beta versions of Android 15.
Temporary solutions and recommendations:
- Switch from gesture navigation to buttonsTo work around this issue, go to Settings > System > Gestures > System Navigation and select "3-button navigation." After restarting and checking that everything is responsive, you can try using gestures again, although the issue may persist until Google releases the final patch.
- If you have a screen protector, try temporarily disabling the "Touch Sensitivity" option to see if gesture recognition improves.
- On recent Xiaomi, OnePlus, Nothing, or Realme models, if you experience similar issues, please check for pending updates or use classic navigation until the issue is resolved.
Google has officially confirmed that it's working on a fix and typically includes the patch in quarterly updates. To check if your Pixel has the fix, go to Settings > System > Software updates and look for the latest version.
Popular app crashes after updating to Android 15: Instagram and other apps
With each major Android update, it's common to encounter temporary incompatibilities with third-party applications . Instagram is the most prominent example with Android 15: numerous users have reported that the app crashes, fails to load stories, prevents interaction with certain elements, or simply closes unexpectedly, especially on Google Pixel phones and some Samsung Galaxy devices.
Reasons for error:
- Incompatibility with the installed version of Instagram and the new Android 15 permissions or APIs.
- Errors in the integration of the notification system and on-screen interaction.
Practical solutions:
- Update Instagram to the latest version (recommended at least version 353.1.0.47.90) from the Google Play Store. If the error persists:
- Try a previous stable version (such as 349.3.0.42.104), downloading the APK from trusted sources, and disabling automatic updates.
- Clear the app cache and data in Settings > Apps > Instagram.
- Restart your phone after each change.
It's recommended to always keep both your Android system and your daily apps properly updated . Google and Meta (Instagram's parent company) are working together to resolve these types of errors as quickly as possible.
Other services affected (to a lesser extent) include WhatsApp, TikTok, some banks, and streaming apps, especially in the first few days following the major update.
Errors in OTA updates and risk of complete device bricking
One of the most serious errors, and one that has generated the most concern in the community, is the failure during the installation of the OTA (Over The Air) update , especially in Developer Preview versions. Some users have received a message that "the device is damaged" or have experienced crashes that render the phone unusable after downloading and attempting to install it.
In these cases, the solutions involve more technical steps:
- Flash the full system image using official tools such as Android Flash Tool, after downloading the corresponding image from Google developer sites.
- If you do not have advanced knowledge, it is advisable to go to the official technical support to avoid further damage.
- Google often pauses the distribution of faulty OTAs and posts official notices on its forums and support channels.
Whenever possible, back up your data before updating and wait until the initial system updates are more settled, especially if your device is critical to your daily operations.
NFC performance and operation issues
If you've noticed that your phone can't use NFC after the update or is failing to make mobile payments , you're not alone. Android 15, in its early betas and releases, had issues that prevented this feature from working correctly. The problem usually affects digital wallet apps and contactless payment systems.
What to do if NFC doesn't work?
- Update to the latest Android 15 revision available for your model. Google has released quick fixes, such as the Beta 1.1 update, that address this issue.
- If the update still doesn't arrive automatically, you can download the factory image from the official website and perform the update manually.
- Make sure that NFC settings are active (Settings > Connected devices > NFC).
In most cases, once the latest patch is installed, mobile payments and NFC data exchange return to normal.
Specific bugs after security updates: Notifications and background apps
Some Google Pixel users have noticed that, after security patches following the major update, notifications are delayed, disappear, or simply don't appear at all while the device is locked . This issue can affect WhatsApp messages, incoming calls, and critical notifications from banking or system apps.
Why does it occur?
- A conflict in the management of background notifications while the screen is off.
- Internal issues in the notification queue after intermediate security updates.
Temporary solutions you can try:
- Go to Settings > Display > Screen timeout and set so that the screen never turns off, thus avoiding the loss of notifications when blocked (only recommended as a temporary solution).
- Stay tuned for new updates, as Google typically fixes these issues through monthly patches.
Issues with the Private Space feature and hidden app management
Private Space is one of the most anticipated new features of Android 15. It allows you to keep apps, files, and sensitive data in a separate environment, inaccessible to other apps or users. However, its initial integration has not been without its problems:
- App icons disappear when activated.
- Failure to create the space for the first time or sudden crashes when trying to access it.
- Apps that don't appear after moving them to the private space or that lose their previous settings.
Google has released several beta updates (up to version 2.2 and later) to fix these bugs. If you're still having problems, it's best to install the latest version of the system available for your model. Learn about the new features of Nothing OS 3.0 for devices that have updated to Android 15.
Battery reduction, overheating, and battery life issues after updating
It's relatively common for the system to take a few days to "adapt" and optimize resource usage after a major update. However, several users (especially Google Pixel 6a and Xiaomi device owners) have reported:
- Decreased battery life, even without changing usage habits.
- Feeling overheated in simple tasks or when leaving the mobile phone charging.
- Slower wireless charging or failure to detect Bluetooth accessories.
How to minimize the impact?
- After an update, Leave your phone plugged in, connected to Wi-Fi and without intensive use for several hours (even overnight), to complete the internal optimization processes.
- Check for apps that are consuming too much battery by going to Settings > Battery > Battery usage, and close or uninstall any that cause problems.
- Update all your apps and the system itself as soon as patches are available.
Expert tips to avoid problems when updating to Android 15
- Make a full backup of your data, apps, and settings before starting the update process. That way, if something goes wrong, you can restore everything quickly.
- Make sure your battery is above 50% and keep your phone connected to a stable Wi-Fi network during the download and installation.
- Check forums, support websites, and specialized news to see if other users with your same model have reported serious issues. If so, consider waiting for more stable versions.
- Don't try drastic solutions on your own if you're not technically experienced (such as flashing ROMs or modifying internal files), as this could make the situation worse and void your warranty.
By following these steps, you can almost completely minimize the risk of experiencing crashes, data loss, or persistent issues after updating your device to Android 15.
