When your Nothing Phone (2) keeps closing apps unexpectedly, it breaks your flow and can be a real headache. This usually happens when an app hits a snag it can't recover from, forcing Android to shut it down. The good news is you can almost always fix this yourself without much fuss.
I'd start with a simple restart. Just press and hold the power button for about ten seconds until the screen goes black and the phone reboots. This clears out any temporary glitches in the system memory that might be tripping up your apps.
Update Your Apps and Nothing OS
Outdated software is a common culprit. Developers constantly push updates to squash bugs, and if you're running an old version of an app or the system itself, you're more likely to run into crashes. Head to the Google Play Store, tap your profile icon, and go to "Manage apps & device" to see all available updates.
While you're there, check for a system update too. Go to Settings > System > System update. Keeping Nothing OS current ensures better compatibility and stability with all your apps, especially on newer versions like Android 15 with Nothing OS 3.0.
Free Up RAM and Storage Space
Your Phone (2) has capable hardware with the Snapdragon 8+ Gen 1 chip, but if you have too many apps running in the background, it can still run out of working memory (RAM). Swipe up from the bottom and hold to enter the recent apps view, then swipe away apps you're not using.
Low storage space can also cause apps to misbehave. They need room to create temporary files and data. Take a few minutes to clear out old downloads, offload photos to the cloud, or uninstall apps you haven't touched in months. You can check your storage under Settings > Storage.
Clear an App's Cache and Data
Sometimes, the temporary files (cache) an app stores get corrupted. Clearing them gives the app a fresh start without deleting your login info or saved progress. For more stubborn issues, clearing the app's data resets it completely, like it was just installed.
Go to Settings > Apps > See all apps. Find the app that's closing, tap on it, and select "Storage & cache." Tap "Clear cache" first. If the problem continues, you can try "Clear storage" or "Clear data," but be aware this will log you out and reset the app's settings.
Check for Overheating and Battery Settings
The Snapdragon chip in the Phone (2) is powerful but can get warm during intense gaming or video editing. If the phone gets too hot, it may throttle performance or close apps to cool down. If you notice the back getting warm when apps crash, give the phone a break to cool off.
Also, check your battery optimization settings. Go to Settings > Battery > Battery optimization. For the problematic app, you might try setting it to "Don't optimize" to see if that stops Android from restricting its background activity, which can sometimes cause it to close.
Reinstall the Problematic App
If one specific app is the only troublemaker, a fresh install often does the trick. This replaces all the app's files, removing any deep-seated corruption. Press and hold the app's icon on your home screen and tap "Uninstall." Then, just head back to the Play Store to download it again.
Before you reinstall, it's worth checking the app's Play Store page to see if other users are reporting similar crashes in the reviews. This can tell you if it's a widespread issue with a recent update that you might need to wait out.
Review Glyph Interface and Accessibility Settings
The unique Glyph Interface on the Nothing Phone (2) is fantastic, but heavy use of the LED patterns can contribute to battery drain under certain conditions. While it's not a direct cause of app crashes, ensuring your system isn't under unnecessary strain is good practice.
You might also look at any accessibility services you have enabled. Sometimes, third-party apps that overlay on the screen or read content can conflict with other apps. Go to Settings > Accessibility and temporarily turn off any services you don't actively need to see if stability improves.
Boot into Safe Mode
This is a great way to figure out if a third-party app you downloaded is causing the problem. Safe Mode temporarily disables all apps you installed yourself. Press and hold the power button, then on the power off menu, press and hold "Power off" until you see the option to reboot to Safe Mode.
If your apps stop closing in Safe Mode, you know one of your installed apps is the culprit. Start by removing any recent downloads, or uninstall apps one by one (starting with utility or customization apps) until the problem stops in normal mode.
