Why Your Downloads Keep Stalling — 5 Causes and Fixes

1. It stops when the screen turns off

This is the most common one. If the app runs the transfer as ordinary work, the system reclaims the process once the screen goes off and the download dies with it.

The fix is on the app side: a downloader that uses a foreground service keeps running with the screen off. The giveaway is whether a progress notification stays in your shade the whole time.

2. Manufacturer battery savers put the app to sleep

Samsung, Xiaomi and others aggressively suspend background apps with their own power-saving layers. That is why an app that behaves on stock Android stalls on one specific phone.

Excluding the app from battery optimisation — or setting it to 'unrestricted' — resolves most of these cases.

• Settings → Battery → check background usage limits
• Set the app to unrestricted / exclude from optimisation
• Also remove it from any manufacturer 'sleeping apps' list

3. Switching between Wi-Fi and mobile data

Walking out of Wi-Fi range drops the connection for a moment. An app without resume support starts the whole file again from zero.

An app that resumes using HTTP Range requests continues from the byte it stopped at, saving both time and data. A Wi-Fi-only option can also hold transfers until you are back on Wi-Fi.

4. You are out of storage

A large video that runs out of space fails quietly, and some apps show nothing more than a stalled progress bar.

Compare the file size shown before download with your free space. This is another reason an app that reports the true size up front is worth having.

5. The server does not support resuming

Some servers refuse partial (Range) requests. When that happens, even a well-built app cannot continue mid-file and has to start over.

In that case, make sure you are on stable Wi-Fi before starting, and begin large files where you can finish them in one go.

In short

Causes 1 and 2 come down to the app and system settings, 3 to resume support, 4 to checking ahead, and 5 to the server.

VidGet handles the parts an app can control, by default: foreground-service downloads, Range-based resume, real file sizes shown before you commit, and a Wi-Fi-only option.
