How to Fix Samsung Galaxy Mobile Hotspot Keeps Disconnecting

Samsung Galaxy mobile hotspot disconnecting is usually caused by battery optimization, unstable network bands, idle timeout settings, or software glitches. A reliable galaxy mobile hotspot fix is to disable power saving for hotspot-related apps, switch hotspot band, keep the screen awake during testing, and update network settings if Samsung hotspot drops continue.

Steps

Open Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot and turn off any Auto turn off hotspot or idle timeout option if available.
Go to Settings > Battery and device care > Battery and disable Power saving mode. Exclude hotspot-related system services from sleeping apps if the model allows app battery control.
In hotspot settings, change the band from 5 GHz to 2.4 GHz, or test the opposite option. Band instability often causes tethering disconnect Samsung complaints.
Restart the phone, then reset network settings under Settings > General management > Reset > Reset network settings. Reconnect devices after the reset.
Install the latest One UI and carrier updates. Outdated modem firmware often causes random hotspot drops during long sessions.

Common Issues and Fixes

Hotspot disconnects after a few minutes — likely cause: battery optimization or idle timeout — fix: disable power saving, allow hotspot to stay active, and test with the screen unlocked.
Connected device shows no internet — likely cause: weak mobile data signal or carrier throttling — fix: confirm mobile data works on the phone first, then move to a stronger LTE/5G area.
Only some devices keep dropping — likely cause: band compatibility issue — fix: switch between 2.4 GHz and 5 GHz and reconnect the affected device.
Hotspot turns off when the screen locks — likely cause: aggressive sleep management — fix: remove battery restrictions and test while charging.
Frequent drops after software changes — likely cause: corrupted network profile — fix: reset network settings and re-enter hotspot name and password.

Quick Tips

2.4 GHz usually offers better range and stability, while 5 GHz is faster but less stable through walls.

Some carriers limit tethering speed, session length, or total data use even when the hotspot feature is enabled.

VPN, private DNS, or data saver can interfere with hotspot routing on some Galaxy models. Disable each one temporarily for testing.

Overheating can force hotspot shutdown during gaming, downloads, or charging in warm environments.

🤔Note:

If the hotspot works only briefly, test with the phone screen unlocked and power saving turned off before changing more advanced settings.

💡Protip:

When one laptop or tablet keeps dropping but others stay connected, switching between 2.4 GHz and 5 GHz is often the fastest fix.

Option	Best For	Limitation
2.4 GHz hotspot	Stable range	Slower speeds
5 GHz hotspot	Faster nearby connections	Shorter range, more drops
Network reset	Software-related issues	Removes saved Wi-Fi and Bluetooth pairings
Carrier update	Tethering profile issues	Depends on carrier rollout

Why does Samsung hotspot keep disconnecting when another device is idle?

Some Galaxy models stop tethering to save power when traffic is low. Disabling hotspot auto turn-off and battery restrictions usually fixes the idle disconnect.

Does resetting network settings fix Samsung hotspot drops?

Resetting network settings often helps when saved profiles or modem settings are corrupted. The reset is most effective after updates, SIM changes, or repeated samsung hotspot drops without a signal problem.
