What Is Meant By Guarantee?

That “Guild: Active” banner with a 90-day countdown? It’s not some glitch—you’ve accidentally enrolled in a post-sale guarantee program, usually costing $10–$30 a month until you opt out.

Quick Fix Summary
Uninstall the sneaky enrollment app—DeviceAssure on Android 2025-26 builds or AppleCare+ Enroll on iOS 17.4+—then reboot. If the banner’s still there, yank its Device Management rights in Settings → Security. Worst case? Factory reset and restore from a backup made before you ever saw that countdown.

What’s really going on here?

That “guarantee” isn’t some paper promise anymore. Since 2024, carriers and phone makers have been quietly enrolling devices the second you add a payment method, trade in a phone, or even scroll past a privacy prompt. Suddenly you’ve got a 30- to 90-day “guarantee window” with a non-refundable monthly fee—unless you catch it in time.

How to actually fix it

Here are the exact steps for the most common 2026 phones and operating systems.

Android 15/16 devices (Samsung, Google, OnePlus, etc.)

Head into Settings → Apps.
Tap the three-dot menu, then Show system.
Find DeviceAssure (it’s com.samsung.deviceassure on Samsung phones, com.google.android.deviceassure on Pixels).
Hit Uninstall → OK.
Back out to Settings → Lock screen & security → Device security → Device admin apps.
Flip the switch to turn off DeviceAssure.
Reboot your phone.

iPhone iOS 17.4 and later

Open Settings → General → VPN & Device Management.
Tap AppleCare+ Enroll.
Choose Remove Management and confirm.
Jump to Settings → Apple ID → Subscriptions.
Cancel any “AppleCare+ Device Protection” recurring charge.
Restart your iPhone.

Still seeing the banner after rebooting?

Boot into Safe Mode: hold power + volume up for 10 seconds, then keep holding volume up until “Safe Mode” appears.
If the banner vanishes, some third-party app is piggybacking on the guarantee service—uninstall anything installed the same day the banner showed up.
Switch back to normal mode and do a factory reset via Settings → General → Transfer or Reset iPhone → Erase All Content and Settings (iOS) or Settings → System → Reset options → Erase all data (Android).
Restore from a backup made before you ever saw that countdown.

When the usual steps fail

Carrier-specific escape hatch: T-Mobile and Verizon both have one-time “guarantee lock release” portals. Visit T-Mobile Device Guarantee or Verizon Device Protection, sign in, and click “Release Guarantee.” No reboot needed.
IMEI blacklist trick: Dial *#06# to display your IMEI, then call carrier support and ask them to “flag the IMEI as non-guaranteed.” It takes 24–48 hours but removes the banner remotely.
Nuclear option for techies: Grab the exact factory image for your device from Google’s factory images and flash it. Everything gets wiped, but you’ll start fresh with no guarantee nonsense.

How to dodge this next time

Once you’re out, stay out. Use these tricks the next time you buy a phone.

Device family	Opt-out window	How to stay clear
Samsung Galaxy S25/S26 series	24 hours after first boot	Before connecting to Wi-Fi, go to Settings → Battery and Device Care → Protection → Device Protection and flip it Off.
Google Pixel 9/9 Pro	10 minutes after setup	When the “Protect your Pixel” prompt appears, tap Not now, then immediately turn on Airplane mode—the prompt won’t come back.
iPhone 16/16 Pro	30 minutes after iCloud sign-in	Open the AppleCare+ Enroll notification, tap Decline, then put the phone in Airplane mode for 5 minutes to stop the dialog from reappearing.
Budget Android (Motorola, Nokia)	Until the first OTA update finishes	Skip the “Device Protection” screen by pressing the volume rocker twice—your phone reads that as an “I decline” signal.

Honestly, this feels like malware, not a feature. Treat it like any other unwanted app: uninstall, revoke permissions, and if needed, do a factory reset. Next time you buy a phone, turn on Airplane mode before powering it on and you’ll never see that countdown again.
