Samsung battery settings

This app used to be called MineProxyDroid. If you followed an old link or forum post, the app you are looking for is now MC LAN Proxy — same app, same developer.

Samsung is the strictest of the mainstream Android brands about closing apps in the background, and it is the most common reason a Galaxy phone drops a Minecraft session after a few minutes.

There are three separate settings, and changing only one is why people report that they already turned battery optimisation off and still get disconnected. Do all three.

On the free version, check the session limit first. A free session lasts 12 minutes and then stops on purpose, which looks identical to the problem this page is about. The main help page covers how to tell them apart.

Step 1 — Remove it from battery optimisation

Open Settings → Apps
Tap the ⋮ menu in the top right corner
Tap Special access
Tap Optimise battery usage
Change the dropdown at the top from Apps not optimised to All apps
Find MC LAN Proxy and turn its switch off

Step 2 — Stop it being put to sleep

Open Settings → Battery
On older phones this is Device care or Battery and device care.
Tap Background usage limits
Check Sleeping apps and Deep sleeping apps — if MC LAN Proxy is in either list, remove it
Turn off Put unused apps to sleep

That last switch is the one everybody misses. While it is on, Samsung puts apps back to sleep after a few days of not opening them — three days by default — even ones you woke up by hand. That is why the app can work perfectly for a week and then start dropping again for no apparent reason.

Step 3 — Allow unrestricted battery use

Open Settings → Apps and tap MC LAN Proxy
Tap Battery
Choose Unrestricted

Some versions of the app show a warning card on the main screen with an Open settings button that jumps straight to this screen. If your copy has it, use it. If it is not there, your version does not include it yet — the steps above do the same job by hand, and steps 1 and 2 have to be done that way regardless.

If it still drops

Turn off Power saving mode while you play: Settings → Battery → Power saving.
Turn off scheduled optimisation. Anything that optimises the phone automatically — Auto optimise daily on older Device care menus, or the automation options under Settings → Battery — will otherwise undo the settings above overnight.
Check Adaptive battery under Settings → Battery → Background usage limits and turn it off.
Check notifications are allowed. On Android 13 and newer, blocking notifications also hides the ongoing "proxy running" notification, which is part of what keeps the app alive.

Older Galaxy models (S8, S9, S10 and similar)

These use the older Device care menus, where the equivalent settings live in different places.

Galaxy S8

Settings → Device maintenance → Battery
Scroll to Unmonitored apps
Tap the ⋮ menu and add MC LAN Proxy to the list
Or switch App power monitor off altogether

Also make sure Edge lighting is not enabled for the app.

Galaxy S9 and S10

Open Device care from Settings
Tap Battery
Tap the ⋮ menu and open Settings
Disable every toggle except notifications
Open Sleeping apps and wake them all with the bin icon
Make sure Put unused apps to sleep and Auto-disable unused apps are both off

Sessions still ending? If all of the above is done and it still drops, the cause may not be the battery manager at all. The main help page covers the other possibilities — weak Wi-Fi where the phone is sitting, a server that has gone down, and router settings that block devices from seeing each other.
