KDE Connect will not pair

Paired means your phone and PC know each other. Not reachable means the phone is not answering right now. One of these four steps brings it back in almost every case.

1. Open the KDE Connect app on your phone. Android puts background apps to sleep. Opening it once reconnects within a few seconds. This alone fixes most cases.
2. Let it run in the background. In your phone settings, exclude KDE Connect from battery optimization (sometimes called battery saver or app sleep).
3. Same Wi-Fi on both sides. Phone and PC must be on the same Wi-Fi network. Mobile data does not work, and guest networks often block devices from seeing each other.
4. Click Refresh after each step. On the Your phone page, the row turns green when the phone answers. Then click Test connection for the final proof.

QuickText can see your phone, so both are on the same Wi-Fi with KDE Connect running. It just needs pairing.

1. On the Your phone page, click Pair next to your phone.
2. Pick up your phone and tap Accept in the KDE Connect app.
3. The status changes to Ready to send. Click Test connection to confirm.

QuickText cannot see your phone at all. Usually KDE Connect is not running on the phone, or the two are on different networks.

1. Open the KDE Connect app on your phone. If it is not installed yet, get it from the Play Store first, then open it.
2. Put both on the same Wi-Fi. Not mobile data, and not a guest network.
3. Click Refresh on the Your phone page. Your phone should appear in the list.

Still nothing? Windows Firewall may be blocking KDE Connect. On the Your phone page, run Check my setup: when no phone is found, it offers a firewall button. Make sure KDE Connect is allowed for private networks (it uses ports 1714 to 1764).

QuickText could not find KDE Connect on this PC. There are two possible reasons.

1. It is not installed. On the Your phone page, click Get KDE Connect to open the Microsoft Store, or install it from apps.microsoft.com/detail/9n93mrmsxbf0.

2. It is installed in a custom location. Tell QuickText where it is. Go to Settings > Advanced > Where KDE Connect is installed, click Browse, and point it at your KDE Connect folder.

If QuickText hangs or shows a permission error when it connects, your antivirus or firewall is most likely blocking it.

1. Temporarily turn off your antivirus or firewall and try again.
2. If that fixes it, add QuickText to your exceptions (whitelist it), then turn your security software back on.

QuickText is safe. Major tools like Windows Defender and Kaspersky show it as clean. More detail here: Antivirus or firewall warning (false positive).
