How can I stop my apps from constantly crashing on my phone?

General

My apps keep crashing randomly on my phone, sometimes right after I open them and other times in the middle of what I’m doing. I’ve tried restarting and clearing some storage, but it still happens. It’s getting in the way of work and everyday use. Can someone explain what might be causing this and what steps I can take to fix or prevent these crashes?

First thing, figure out if it is one app or many.

  1. Basic checks
  • Restart the phone again, then leave it for 1–2 minutes before opening anything.
  • Check your storage. If you are under 2–3 GB free, apps crash more often. Move photos and videos off or delete junk.
  • Turn off battery saver and any “RAM cleaner” or “phone optimizer” apps. Those often kill apps in the background.
  1. Update stuff
  • Open your app store.
  • Update all apps.
  • Update the system software if there is a pending update. Bugs in older builds cause random crashes.
  1. Clear problem app data
    For each app that crashes a lot:
  • Go to Settings → Apps → [App name].
  • Force stop.
  • Clear cache.
  • If it still crashes, Clear storage / data, then log in again.
    This fixes corrupted local data most of the time.
  1. Check for bad apps or mods
  • Uninstall any “RAM booster”, “cleaner”, free VPN, or shady keyboard app.
  • If crashes started after installing some new app, uninstall that one and test for a day.
  • If your phone is rooted or you use modded APKs, those break more often than normal apps.
  1. Check overheating and hardware
  • If the phone gets hot, apps crash more. Take off the case, avoid gaming or heavy stuff for a bit, see if it improves.
  • If it only crashes when using the camera, GPS, or a certain sensor, that can point to hardware trouble.
  1. Safe mode test
    On Android: hold power button, then long press “Power off” until “Safe mode” pops up. Boot into that.
  • In safe mode only system apps run.
  • If crashes stop, some third party app is the cause. Reboot normally, then remove apps one by one until it stops.

On iPhone you do not have a normal safe mode, but you can:

  • Remove VPNs, profiles, and weird keyboards.
  • Test after each removal.
  1. Backup and reset if nothing helps
  • Backup photos, contacts, chats.
  • Factory reset the phone from Settings.
  • Set it up fresh, do not restore all apps at once. Install a few at a time and watch for crashes.
  1. When to suspect hardware
  • Crashes across almost every app.
  • Random reboots.
  • Freeze on boot logo.
  • Lines or glitches on screen.

If those show up after a reset, the storage or RAM is likely failing. At that point, service center or replacement is the realistic fix.

If all the usual stuff still didn’t fix it (restart, updates, cache, safe mode etc. like @sonhadordobosque said), I’d look at the pattern of crashes instead of just poking random settings.

  1. Check when it crashes

    • Only on mobile data, fine on Wi‑Fi → likely network / DNS / VPN issue.
    • Only on Wi‑Fi, fine on data → router / DNS / ad‑blocker apps.
    • Only when keyboard pops up → try switching to the default keyboard for a day.
    • Only when notifications arrive / multitasking → could be aggressive memory management or an overlay app.

  2. Turn off “special” stuff temporarily
    In Settings:

    • Disable any accessibility apps (password managers with autofill, screen filters, button remappers, etc.).
    • Turn off screen overlay / bubble apps (chat heads, floating toolbars).
      These can conflict and cause hard‑to‑trace crashes. Test for a few hours.

  3. Look at logs if you’re up for something nerdier

    • On Android, enable Developer options → turn on “Bug report shortcut” or connect to a PC and use adb logcat.
    • Open the app, wait for the crash, then check what process or error pops right before it dies.
      If you keep seeing the same library or service name, that narrows the problem.
      Yeah, it’s a pain, but it actually tells you if it’s OS, app, or some other service.

  4. Try a different user profile / account

    • On Android: add a new user or guest profile, install just 2–3 of the problematic apps there.
    • On iOS: sign out of iCloud for a bit or create a new Apple ID to test a single app.
      If apps behave fine in a clean profile, your main profile data or sync settings are borked, not the hardware.

  5. Check your sync & backups
    Sync storms can kill performance and crash apps:

    • Temporarily turn off auto backup (Google Photos, cloud drives, chat backups) and heavy sync like Contacts / Calendar from work accounts.
    • If the crashes slow down when sync is off, re‑enable things one by one. Some corporate accounts push buggy policies.

  6. Be suspicious of “partial” factory resets
    A lot of people do a reset then restore everything from backup instantly. That just restores the exact same corruption.
    If you do reset, set up as new:

    • Only restore contacts and photos from cloud.
    • Manually reinstall apps.
    • Do not restore app data wholesale.
      It’s annoying, but it’s the only way to rule out a toxic backup.

  7. When it is the OS itself

    • If a whole class of apps crash (for example, all banking apps or all games using a specific graphics engine), it can be a bad OS build.
    • If possible, join beta channel or roll back to a previous stable version using official tools.
      This is one place I slightly disagree with just “update everything.” Sometimes the newest update is the problem and you want to step back, not forward.

  8. Check for regional issues
    Some apps crash more in certain regions because of ad or analytics SDKs that misbehave with local networks or regulations.

    • Try a reputable VPN briefly. If crashes magically stop when routed through another country, it is probably the app plus region combo, not your phone.
      Not a permanent fix, but a hint.

If you post details like phone model, OS version, a couple of apps that crash the most, and exactly what you’re doing 2–3 seconds before the crash, people can usually spot a pattern pretty fast. Right now it sounds like there’s likely one underlying trigger you just haven’t pinned down yet.

Skip the obvious stuff others already covered and look at a few “less talked about” angles:

  1. Thermal throttling & hardware issues

    • If crashes spike when the phone is hot (gaming, video calls, GPS), your SoC or battery might be degrading.
    • Install a monitoring app and watch CPU temp and frequency. Sudden drops plus crashes often point to hardware, not software.
    • If it also shuts down or reboots randomly, start thinking battery / mainboard, not just apps.

  2. Storage health, not just free space

    • You said you cleared storage, but failing flash can cause random app deaths even with free GBs.
    • Signs: files that refuse to copy, photos occasionally corrupt, very slow install / update times.
    • If your device is old and has been kept near full for years, this gets more likely. In that case, backing up and planning a replacement beats endless tweaking.

  3. SD card traps (if you use one)

    • Apps installed on a flaky SD card or using it as “internal storage” can crash constantly.
    • Move apps back to internal storage and remove the card for a full day. If stability returns, the card is the villain.
    • Long term: a high‑endurance card or, better, internal storage only for critical apps.

  4. Per‑app “repair” instead of global fixes
    Rather than nuking everything, try deep‑cleaning one or two of the worst offenders:

    • Clear both cache and storage for that app, then log in fresh.
    • If it syncs to a cloud account (social, mail, notes), this is safe.
    • If only a few apps misbehave while others are solid, the OS is probably fine and those apps (or their data) are the problem.

  5. Be careful with “aggressive cleaners”
    This is where I partially disagree with the generic advice to just “optimize” and “clean”:

    • Task killers, RAM boosters and some battery savers can terminate background components of apps, which looks exactly like a crash.
    • Disable those for a day, and also whitelist your important apps from battery optimization, then test again.

  6. Account corruption & sync conflicts
    @sonhadordobosque mentioned patterns and profiles, which is solid. I’d add:

    • Temporarily remove one account at a time (Google / Apple ID is last) and especially any work / school account.
    • Reboot, test core apps. I have seen buggy MDM / corporate policies silently kill apps on launch.

  7. Decide if it is worth a “true fresh start”
    If crashes survive all of that, a real clean install is the acid test:

    • Backup only photos, contacts, authenticator codes and chats (with export, not full device image).
    • Factory reset and do not restore from the automatic phone backup. Set up as brand new.
    • Install just 3 or 4 key apps and use the phone for a day. If it is rock solid, your previous backup or old app data was poisoned.
    • If it still crashes in that bare state, that strongly hints at hardware or the OS build itself.

  8. Compare notes & next step
    @sonhadordobosque already covered diagnosing patterns like network vs Wi Fi and safe mode. Combine that with:

    • Temperature / load checks
    • SD card test
    • A no‑backup clean install
      and you will usually pin it on one of three: a specific app, your account / policies, or aging hardware.

If you list your phone model, OS version, a couple of the worst apps, and whether it heats up or uses an SD card, people here can probably narrow it to one of those pretty quickly.
