A young man carefully repairing a phone at a table

Short answer

Before you start

Note the dates: when you handed the phone in and when you got it back. Applore shows when each app was installed, so those dates let you tell a new app from an old one.

The five-minute check with Applore

  1. Install Applore from Google Play if it is not already there (Android 8.0 and up), and allow the consent screen that explains what the check reads.
  2. Open the Suspicious App Checker from the Security section of Home. It compares every installed app with a reviewed, signed list of known stalkerware and harmful apps [2], shows what Google Play Protect reports if it is on, and flags warning signs: installed from outside an app store, hidden icon, accessibility, notification or device admin access, a copy of a popular app without its publisher’s signature.
  3. Sort out the dates. For each flagged app, About this app shows when it was installed. An app installed while the phone was away deserves a closer look than one you have had for a year.
  4. Open Safety Check and go through every item. It opens the right screen for each: accessibility services, notification access, device admin apps, Google signed-in devices, third-party account access, Maps location sharing, Family Link, Find Hub, Photos partner sharing, Gmail forwarding and WhatsApp linked devices. [1] Mark each one as checked.
  5. Check the keyboard and developer options by hand: Settings › System › Languages & input › On-screen keyboard, and whether Developer options has appeared with USB debugging on. Menu names vary by phone maker.
  6. Change your PIN or password if the shop had it, and remove any account you did not add.

Each flagged app shows a level: Known monitoring app High Worth a look Not flagged. The levels describe how strong the warning signs are, not what the app has done.

If you saved a snapshot first (Pro)

Phone back check is part of Applore Pro. Before you hand the phone over, you save a snapshot of its apps and settings. When it is back, you tap Check my phone and Applore lists what changed, most serious first:

  • new, removed, replaced, updated or reinstalled apps, and whether a new app came from an app store;
  • an app that was given accessibility access, notification access or device admin rights;
  • a different keyboard;
  • a removed screen lock;
  • developer options or USB debugging turned on.

The snapshot and the comparison stay on your phone. Only take a new snapshot while the phone is in your hands. Phone back check.

Before the next repair

  • Back up photos, contacts and anything else you want to keep. Repairs can end in a reset.
  • Save a snapshot in Phone back check (Pro) just before you hand the phone in.
  • Ask about a repair or maintenance mode. Some phone makers offer one that hides your data during a repair. Check your phone maker’s help pages.
  • Set a temporary PIN for the shop and change it back afterwards.
  • Lock what is private with App Lock, so banking, messages and photos stay behind your PIN even while the phone is unlocked. App Lock.

Common problems

Applore flagged an app that came with the phone

Apps installed by the phone maker’s firmware are treated like store installs, so most are not flagged. If one is, read the explanation: a carrier or region app with broad access is common. If you recognise it, mark it as trusted with your PIN.

I cannot find a settings screen Safety Check mentions

Phone makers rename and move screens. Open Settings and use its search bar for the words Applore shows, such as “Accessibility” or “Device admin apps”.

The check found nothing

A Not flagged result means no match with the known list and not enough warning signs. It is a good sign, not proof. A changed PIN and a look through Safety Check cover most of what a check cannot see.

What stays private

The check runs on the phone. The threat list is downloaded and compared on the device; findings, your trust list and any snapshot stay there. The list of installed apps is not sent to analytics or advertisers. Data and privacy.

Questions

Can a repair shop really install something on my phone?

Anyone with the phone unlocked can install an app or change a setting, and a repair often needs the phone unlocked to test the screen or the sensors. That does not mean anything happened. Before the next repair, back up the phone, remove or change your PIN, and ask whether your phone maker offers a repair or maintenance mode that hides your data. Afterwards, run the checks on this page.

I did not take a snapshot before the repair. Can Applore still tell me what changed?

Not what changed, because a snapshot can only be compared with a later one. It can still tell you what is set now: the Suspicious App Checker flags apps with warning signs, and Safety Check opens every place someone could have changed. Both are free. Take a snapshot now, in Phone back check (Pro), so the next time the phone leaves your hands you can compare.

I found an app I did not install. What should I do?

Open it in Applore and read About this app: where it came from, when it was installed and what it can do. An app installed on the day of the repair, from outside an app store, with a hidden icon or accessibility access, is worth taking seriously. Keep a record first: the safe removal steps let you save a report on the phone. If you think the installer could be someone close to you rather than the shop, read before you remove a suspicious app.

Which parts of this are free?

The Suspicious App Checker, Safety Check, the hotlines, Quick exit and the safe removal steps are free in Applore Free and Applore Pro, and show no ads. Phone back check, the snapshot and compare tool, is part of Applore Pro. Compare Free and Pro.
