Why have some apps stopped working on my old phone?
Developers raise the minimum operating system version their app supports, and your phone can no longer go high enough. It is not a fault and there is no fix on the phone itself.

Short answer
The app now requires a newer version of iOS or Android than your phone can install. Developers raise the minimum every year or two, and once your phone has had its last update it falls below the line one app at a time. You cannot force it — the store will offer the last compatible version if one exists, otherwise use the website instead, or accept that the phone has reached the end of its useful software life.
This happens gradually and it is confusing because the phone still works perfectly. Nothing broke. What changed is the floor: each app sets a minimum operating system version, developers raise it as they adopt newer tools and drop old ones, and a phone stuck at an old version silently drifts below one app's floor after another. Banking apps tend to go first because they have the strictest security requirements.
Safety
Step by step
- Check what version your phone is on and whether it can go higher.The software update section of settings shows the current version and whether anything is available. If it says you are up to date on a version that is several years behind current, the phone has had its last update. That single fact explains everything else.
- Look up your model's support position.Manufacturers publish which models still receive updates, and Android security bulletins state the current patch level. Compare your phone's security patch date — shown in the about section of settings — against today. A patch level more than a year old means you are no longer being protected.
- Try the last compatible version from the store.Both stores will offer an older build of an app to a device that cannot run the current one, if the developer left one available. It is worth trying and it often works, but it is a reprieve rather than a fix — the old build will eventually be refused by the app's own servers.
- Use the website instead where there is one.Banking, shopping, travel and government services almost all have a full website. On an old phone the browser is frequently a better route than the app, and it keeps working long after the app has stopped. Add it to the home screen and it behaves much like an app.
- Separate this from an app that crashes.An app that installs and then crashes may simply need clearing and reinstalling. An app the store refuses to install, or that shows a message about requiring a newer version, is the compatibility wall. Different symptom, different cause, do not conflate them.
- Decide honestly about the phone.The question is not whether the phone works. It is whether the security updates are still coming. A phone out of security support that is used for banking and email is a genuine risk, whatever its condition. A phone out of support used for photos, music and calls is fine for years yet.
- Repurpose rather than discard if you replace it.An unsupported phone makes a perfectly good music player, alarm clock, dashcam, remote control, kitchen recipe screen or child's camera — on wi-fi, signed out of your main accounts, with no banking or email on it. That eliminates the security concern by removing what there is to steal.
If it doesn't work
The store says this app requires a newer version
Cause: The phone's OS is below the app's minimum — Fix: Look for a last-compatible version offered by the store, or use the service's website. There is no way to install the current version on an OS the phone cannot run.
An app worked yesterday and now demands an update it cannot install
Cause: The developer's servers stopped accepting the old client version — Fix: Nothing on the phone will fix this. Use the website, or move that service to a supported device. This is the most common way people discover their phone is out of support.
The banking app has stopped and the bank cannot help
Cause: Banks enforce minimum OS versions strictly for security reasons and will not make exceptions — Fix: Use online banking in the browser, telephone banking, or a supported device. It is worth telling the bank the phone is unsupported, because it may affect how they treat your account security.
The phone says it is up to date but the version is old
Cause: The phone has received its final update — Fix: This is the answer, not a bug. Check the manufacturer's support list to confirm, and plan accordingly.
Questions people ask
Can I install a newer Android myself?
Custom versions of Android exist for popular older models and some are well maintained, but installing one voids warranties, may break banking apps and contactless payment permanently, and can leave the phone unusable if it goes wrong. It is a hobbyist route, not a practical fix.
How long should a phone get updates?
It varies enormously and is worth checking before you buy. Manufacturers now publish commitments in years from the model's release, and the range across the market is wide. The commitment runs from release, not from your purchase.
Is it dangerous to keep using it?
It depends what you use it for. Unpatched flaws are exploited through what you connect to — websites, messages, and networks. A phone used for banking and email is exposed; one used offline for music is not.
Will my photos still be safe?
The photos are fine. But check that the photo sync app still works — cloud services also raise their minimum versions, and a phone whose photo app has stopped syncing is quietly no longer backing up.
