What is Sync Control?

Running the same daily quests on 20 game accounts, one device at a time? Want to test an app on 10 devices in parallel to compare behavior? Sync Control is built exactly for that.

Quick definition

Sync Control lets you control multiple Cloud Phones simultaneously. You add devices to a grid on the Sync Control page, select the ones you want to receive input, then type or click in the Control Panel — every action is instantly forwarded to all selected devices at once.

Put simply: selected devices receive input, unselected ones don't.

When should you use Sync Control?

A few common scenarios xCloudPhone users rely on:

Daily tasks across many game accounts — if the game's terms allow it, complete dailies, claim rewards, or grind repetitive tasks across your accounts in a single pass.
Test apps on many devices in parallel — check UI/UX, crash behavior, or compatibility across multiple device configurations at the same time.
Manage multiple profiles — when you keep several accounts on separate Cloud Phones, the routine housekeeping happens once instead of N times.
Training or demos — the instructor acts through the Control Panel; learners see the same result mirrored on their devices.

The two features sound similar but solve completely different problems:

Sync Control = many devices you own, running in parallel. You are the only one controlling them. Goal: replicate actions.
Share Sessions = one device of yours, shared with other people for access. Goal: collaboration or handing over control.

If you want "1 person controlling N devices" → Sync Control. If you want "N people controlling 1 device" → Share Sessions.

Requirements

Your account has at least 2 devices currently running. Stopped/paused devices won't appear in the add-device list.
Devices should share the same resolution (or close to it) so click coordinates match.
Stable network — Sync Control streams actions in real time, so high latency can cause noticeable lag between devices.

Tip for newcomers: before controlling dozens of devices, try it with 2-3 devices first to feel out the latency and confirm the actions land cleanly. Once you're comfortable, scale up to dozens or hundreds.

Real-world benefits

Massive time savings — instead of repeating one action 50 times, you do it once.
Consistent outcomes — every selected device receives the exact same sequence of actions, eliminating manual errors.
Easy to scale — operate hundreds of devices with a single keyboard and mouse.
Group management — label devices with a Group, then select the entire group with one click instead of ticking individually.

Things to keep in mind

Warning about mass-action detection: social media platforms and games run anomaly detection. When N devices all perform the same action at exactly the same moment, the platform may flag it as suspicious and trigger checkpoints (verification requests) across many accounts at once.

How to reduce risk:

Split into smaller batches — rather than selecting 100 devices at once, work in smaller groups on different schedules.
Diversify behavior: occasionally deselect a few devices and operate them manually to mimic "real human" patterns.
Respect each platform's Terms of Service. Sync Control is a neutral technical tool — how you use it is your responsibility.

If a device in the group gets checkpointed or signed out mid-session, deselect it before continuing to operate. If you keep going while that device is on a verification screen, your input will unintentionally be sent there.

Terms you'll see

Control Panel: the sidebar on the left — where you type and click, and all currently selected devices receive that input simultaneously.
Selected devices: devices with a checkmark in the grid — only these receive input from the Control Panel.
Group: a label assigned to a set of devices. Used to select an entire group with one click instead of ticking each device individually.
Batch: when a large number of devices are connected, the system processes them in smaller batches automatically to maintain stability.
