Why your Android TV got slow — and how to fix it

A TV that was snappy in year one and crawls in year three has almost always accumulated background services and filled its storage. Android needs roughly 15% free space before it starts thrashing.
Measure before you delete things: check free storage, then look at which apps run at boot. Most slow TVs have three or four apps that were opened once and never closed.
설치 방법
- Check free storage in Settings → Device preferences → Storage. Below 15% is the most common cause.
- Uninstall apps you have not opened in six months, starting with the largest.
- Clear the cache of streaming apps individually; clearing all app data will log you out everywhere.
- Disable auto-start for apps you rarely use. On most Android TV builds this is under Apps → See all → App → Notifications and permissions.
- Replace a heavy stock launcher with a lightweight one — the home screen is redrawn constantly.
- Reboot weekly. Android TV has no scheduled maintenance and long uptimes leak memory.
- As a last resort, factory reset. Back up your app list first; sideloaded apps are not restored.
자주 묻는 질문
Will a factory reset make it fast again?
Yes, temporarily. If the TV is under 2 GB of RAM it will slow down again within a year regardless — hardware, not software, is the limit.
Does a custom launcher really help?
Often, yes. Stock launchers on low-end TVs render recommendation carousels that pull network data on every redraw. A minimal launcher removes that work entirely.
