Troubleshooting

Fixes for common problems: installing, codes, being signed out, required updates and more.

Fixes for the problems people run into most. If none of these help, send us feedback and say what you were doing.

The app won't install

  • "Install blocked" or nothing happens: Android needs your permission to install apps from your browser. When asked, tap Settings, turn on Allow from this source, go back and tap Install again. See Install the Android app.
  • "App not installed":
    • Your phone needs Android 7.0 or newer.
    • Free some space and try again.
    • The download may be incomplete. Delete the file and download it again from the official download site. You can check its SHA-256 fingerprint.
    • If you have a copy of Scrap Exchange from somewhere other than our download site, Android won't install ours over it. Uninstall the old app first.
  • "Older version" or "downgrade": Android doesn't install an older version over a newer one. See Install an older version.

The update won't install

  • Tap Update now again. Interrupted downloads continue where they stopped.
  • If the app asks you to allow installs, turn on Allow from this source for Scrap Exchange, go back, and tap Update now again.
  • "Not enough free space": free the space the message asks for.
  • "This build is signed differently from the app on your phone": uninstall Scrap Exchange once, then install it from the download site. Your account and deals are safe.
  • Still stuck? Install the newest version by hand from downloads.scrapex.ubaidbinwaris.com (opens in a new tab).

I didn't get the sign-in code

  • Check where it went: the screen shows part of the phone number or email address. Codes go by SMS when your phone is verified, and by email otherwise.
  • Email: check your spam or junk folder, and wait a minute.
  • SMS: check you have signal, and that your phone isn't blocking messages from unknown senders.
  • Ask for a new one: wait for the timer, then select Send a new code. Use the newest code.
  • "Too many sign-in attempts": we only send a few codes per hour. Wait an hour and try again.
  • "This sign-in has expired": codes last 10 minutes. Start again with your email and password.

See Sign-in codes and trusted devices.

I was signed out unexpectedly

The sign-in page says why. The most common reasons:

Update required

The app says Update required and has no Later button, or sign-in says "This version of the app is too old to sign in".

See Required updates.

I forgot my password

Use Forgot password? on the sign-in screen. We email you a 6-digit code (it works for 10 minutes). See Sign in.

"Account temporarily locked"

After 5 wrong passwords in 10 minutes, the account is locked for 15 minutes. Wait, or reset your password.

The link in the welcome email works for 5 minutes. On the page it opens, ask for a new link and open the newest one. If you are already signed in, verify with a code instead: see Change or verify your email.

I can't sell (no Sell scrap or My listings)

Your account is set up for buying. Change I want to to Sell scrap or Buy and sell in your profile.

The marketplace doesn't filter by distance

Distance needs your location. Allow location for the site in your browser settings, or for the app in your phone's settings, then try again.

Voice notes don't record on the web

Recording needs Chrome, Edge or Safari, and permission to use the microphone. Allow the microphone for the site in your browser settings.

I can't make an offer

  • It is your own listing.
  • The lot is being auctioned: place a bid instead.
  • The listing is no longer live.

My offer disappeared or says Expired

Offers that get no answer for 48 hours expire. Make a new offer if the listing is still for sale.

Photos won't upload

Use JPEG, PNG or WebP photos up to 10 MB each. A listing can have up to 5 photos.
