Apps & Software
App updates keep your phone secure and running smoothly. Here is how to update apps safely, when it is fine to wait, and how to dodge fake update scams.
The safe way to update apps is boring on purpose: let updates arrive only through the App Store on iPhone or the Google Play Store on Android, turn on automatic updates over Wi-Fi, and treat every "update now" prompt that appears anywhere else as a scam. That one rule blocks the overwhelming majority of malware that reaches phones, because both stores only deliver builds that are cryptographically signed with the original developer's key.
Most updates are not about a redesigned button. When a security researcher reports a flaw, the developer patches the code and ships a new version, and that download is the only path the fix travels to reach your device. Until you install it, your phone keeps running the exact code the attacker already knows how to exploit. This is why "What's New" notes so often read "bug fixes and performance improvements" that vague line is frequently covering a real vulnerability the developer would rather not advertise in detail.
Beyond security, updates keep apps compatible with your operating system. When Apple ships iOS 18 or Google ships Android 15, apps that have not been rebuilt against the new APIs start crashing, losing notifications, or draining battery through background retries. Developers set a minimum OS version and a target SDK level; staying current on both sides keeps that contract intact. Skipping updates for months is how you end up with an app that suddenly force-closes on launch after a system update you did not connect to the problem.
Both platforms let you automate updates while still controlling the network and timing. This is the setup most people should use.
Go to Settings > App Store. Under Automatic Downloads, turn on App Updates. Directly below, tap Cellular Data and set App Downloads to Ask If Over 200 MB (or Always Ask if your plan is tight). That combination keeps small security patches flowing instantly while stopping a 4 GB game from silently draining your data allowance. To update by hand, open the App Store, tap your profile picture, then pull down to refresh the list and choose Update All or update apps individually.
Open the Play Store, tap your profile icon, then Settings > Network preferences > Auto-update apps, and choose Over Wi-Fi only. To trigger updates yourself, tap your profile icon > Manage apps and device > Updates available. Android also runs Google Play Protect, which scans apps for known malware; confirm it is on under the same Manage apps and device screen. Google frequently ships updates as delta patches, downloading only the changed portions of an app rather than the whole package, so most updates are smaller than the app's full size.
The trade-off with full automation is loss of timing control: an app can change its interface or remove a feature overnight. If that bothers you for one or two critical apps, leave global auto-update on and manually manage just those exceptions.
Legitimate updates never arrive as a pop-up while you browse, a text message, or an email link. Every one of those is a red flag, and the patterns are predictable.
If an update offer appears anywhere other than the official store, close it and go to the store directly. The store is the single source of truth, and navigating there yourself removes all the guesswork.
Two conditions make updates painless: a stable connection and enough power. A large title like Call of Duty: Mobile or Genshin Impact can exceed several gigabytes, and pushing that over cellular is slow and expensive. Wi-Fi, ideally Wi-Fi 5 or Wi-Fi 6, is faster and usually uncapped.
Keep the phone above roughly 20 percent battery or plugged in before a major update. Modern stores pause and resume safely if power is lost, so a dead battery rarely bricks an app anymore, but interrupting a large install still wastes time on a re-download. Storage matters too: an update needs room to unpack the new version alongside the old one, so an install can stall on a nearly full phone. On iOS, Settings > General > iPhone Storage offers Offload Unused Apps, which frees space while keeping your data; on Android, clear an app's cache under Settings > Apps > [app] > Storage before retrying a stuck update.
Updating promptly is the right default, but instant is not mandatory. Both platforms often use staged releases: Apple's phased rollout spreads an automatic update across up to seven days, and Google's staged rollout ships to a growing percentage of users. That means a brand-new version occasionally ships a fresh bug before the developer catches it.
If you are about to depend on an app boarding a flight, joining a meeting, paying at a till it is reasonable to postpone until afterward rather than risk a changed interface mid-task. When you hear a release is causing problems, open the app's store page and skim the most recent reviews; a wave of one-star complaints from the last day is a clear signal to wait for the follow-up patch, which usually lands within 48 hours.
The biggest error is turning updates off entirely after one bad experience, then running months-old, vulnerable code across every app. The fix is targeted patience, not blanket avoidance. The second is sideloading paid apps "for free" from third-party APK sites, which is the most common way Android phones get infected. The third is muscle-memory tapping on update prompts inside a browser or a text, the exact behavior scammers rely on. And the fourth is ignoring the operating system itself: keeping apps current while running an outdated OS (Settings > General > Software Update on iOS, or Settings > System > System update on Android) leaves the foundation unpatched underneath everything.
Not easily. Neither the App Store nor Google Play officially supports reverting to an older version, and doing so through unofficial APKs reintroduces the security risk you were avoiding. The practical move is to report the problem in the app's reviews and wait for the developer's fix.
Only if you allow it. Set iOS to Ask If Over 200 MB under Settings > App Store > Cellular Data, and set Android to Over Wi-Fi only under Play Store > Settings > Network preferences. Configured that way, updates wait for Wi-Fi and your data plan stays untouched.
If it appears inside the App Store or Google Play, it is genuine because both stores verify the developer's signature. If it appears anywhere else, a pop-up, a text, a website, an emailed link, it is not a real update. Go to the store and check for yourself.
Update the operating system first when both are waiting, since apps are built to run against the current OS. After a major system update, open the store and refresh your apps so they can adopt any new frameworks the OS introduced.
