What are the main problems after updating to Android 15?

Since the rollout of Android 15, users have reported an increase in bugs and errors related to Bluetooth and wireless connectivity, overall performance, gesture navigation, battery consumption, and the functionality of services like NFC and GPS . While not all devices have been affected equally, there is a clear pattern among Google Pixel models, especially the most recent generations, and some smartphones from brands like Xiaomi.

• Bluetooth drops and disconnections: Problems pairing headphones, smartwatches, cars, and other accessories, as well as sudden disconnections after just a few minutes of use.
• Malfunction in gesture navigation: Difficulty using the "back" gesture, which affects the fluidity of interacting with the system.
• GPS failures and excessive battery consumption: Inaccurate location and rapid battery drain, especially when using apps like Google Maps in high-use mode.
• NFC issues and difficulties with mobile payments: Intermittent errors that prevent contactless payments from being completed without restarting the terminal.
• Unexpected reboots and screen freezes: Random reboots and lock screen freezes, with flickering and slowness, especially if auto-brightness is on.
• Faulty integration with Android Auto: Voice commands fail after first use and loss of functionality with apps like Waze and YouTube Music.

Bluetooth, Wi-Fi, and other connectivity issues on Android 15

One of the most frequently reported problems by users after installing Android 15 is instability in wireless connections. The issues particularly affect Bluetooth connections and, to a lesser extent, Wi-Fi and mobile network connectivity. Users report that:

• Pairing with wireless headphones, speakers and car audio systems It is erratic, sometimes forcing the devices to be continuously unpaired and re-paired.
• Some terminals experience random disconnects during a call, when playing music or simply after a few minutes of standby.
• In corporate environments or with specific routers, Wi-Fi may struggle to maintain a stable connection, resulting in loss of internet even though the icon indicates a connection.

These issues have been detected primarily in the Google Pixel 9 , Pixel 8a , Pixel 6 , and related variants, but they are not exclusive to these models. Various support communities and forums have received similar reports for other brands, especially Xiaomi and some international models.

Gesture Navigation Errors: The Critical Back Gesture Flaw

Gesture navigation has become the most convenient way to interact with Android, allowing users to take full advantage of the screen space without traditional navigation buttons. However, after the Android 15 update, a significant bug has particularly affected the back gesture (swiping from the side to return to the previous screen).

• The system does not respond correctly to the "back" gesture, which generates frustration and loss of control in application navigation.
• Some users have had to revert to button-based navigation, losing the benefits of the full-screen experience.
• Google has confirmed the issue, has already tested internal fixes, and is expected to release a patch or update soon.

Meanwhile, the only temporary option available is to switch to button navigation from settings (System > Navigation mode > 3-button navigation), although this transition may be awkward for those already accustomed to gestures.

GPS, location, and battery life issues: battery drains quickly

Excessive battery drain is another major headache after updating to Android 15. This symptom is often related to faulty GPS and location services, although background apps, system processes, and general optimization bugs can also play a role. To troubleshoot performance issues, see our guide on how to fix corrupted cache errors on Android.

• Users report that Google Maps and other navigation apps cause a sudden decrease in autonomy, completely draining the battery in hours.
• In some cases, the GPS provides imprecise location, losing signal or showing constant jumps in location.
• The problem persists even with location disabled, stating that energy management in the system is poor.

Temporary solutions include enabling " high accuracy mode " in location settings and checking app background data usage. For more details on properly configuring GPS, see our guide to troubleshooting Google Play compatibility issues on Android.

Impact of NFC and problems with mobile payments

NFC has become an essential component for contactless payments and other fast communication functions (access, authentication, etc.). Following the release of Android 15, some users have experienced :

• Recurring errors when trying to pay with a mobile phone on compatible POS terminals, displaying messages such as “The transaction could not be completed.”
• Need to reboot the device so that the NFC system works correctly again for subsequent payments.
• Similar problems arise across various banking and mobile payment apps, both with Google Pay and with proprietary bank apps.

Overall performance, lags, and stutters: Why is my Pixel slowing down?

Although Google Pixel phones have historically boasted outstanding performance, Android 15 has brought with it noticeable slowdowns, lag, minor interface stutters, and drops in app performance . The cause, according to research from the developer community and Google itself, lies in:

• An poor management of kernel resources, which distributes bandwidth between processes and applications inefficiently.
• This causes multiple apps to compete uncontrollably for access to system resources, resulting in stutters and lags, especially when scrolling through menus, messaging apps, social media, or running heavy games.

A prominent developer, Sultan Alsawaf, managed to identify the root of the problem and proposed a kernel-level patch for the Pixel 8 models, which distributes resources optimally, thus restoring fluidity to the device.

Update failure: reboots, screen freezes, and security errors

Several devices have begun experiencing unexpected restarts , especially during simple tasks like putting the phone to sleep or listening to music. These random restarts indicate deep flaws in the integration of Android 15 with each manufacturer's specific hardware layers. Furthermore:

• In lock screen are observed Flashing, freezing, and difficulty unlocking using gestures or biometric methods (fingerprint or face).
• The security system displays conflicting notifications or requires double authentication to perform simple actions, creating confusion.

Android Auto and Google Assistant issues: the "ghost" of voice commands

The Android Auto ecosystem has also faced its share of complications following the arrival of Android 15. Most reports point to the following:

• El Google Assistant It only recognizes the first voice command when connecting the device to Android Auto, ignoring subsequent commands until the app or the device itself is restarted.
• Integration with Waze and YouTube Music failure to issue commands for navigation or music playback.
• The error persists after reboots, using original cables, and updates, and affects both Google Pixel and certain Xiaomi models.

Problems with updates and beta versions: importance of patches and their impact

Beta versions and interim patches have been the primary channel for addressing the numerous bugs that have emerged since the Android 15 update. However, it's important to keep in mind that:

• Beta versions may contain additional bugs which affect stability, app compatibility and performance, so they are not recommended for users who depend on their mobile phone on a daily basis.
• Google launches QPR (Quarterly Platform Releases) quarterly with fixes, but not all of them immediately resolve the main issues reported by users.
• Some known issues include loss of sensor functionality, wireless charging issues, failure to execute calls, and erratic behavior in system menus.

It is essential to always keep your device updated and participate in official support forums, reporting errors in detail to speed up the arrival of solutions.

Diagnostic Tools in Android 15: Detect and fix problems from within the system

One of the new features in Android 15 is the built-in troubleshooting tool . This allows users to identify the source of connectivity, battery, and temperature issues without installing any external apps.

1. Access the Device settings and look for “Diagnosis” in the top bar.
2. You can analyze the status of the battery, mobile and WiFi connectionsas well as a internal temperature Of the device.
