If the Xiaomi Smart Projector L1 Pro lags in terms of system operation, please refer to the following details:
1. Please determine whether you have installed too many third-party APPs. If so, please uninstall them and try again;
2. Please check whether the system version is the latest. You can update the system to the latest and try again;
3. Please confirm whether the heat dissipation is normal. If the heat dissipation is not smooth, it will cause the internal temperature of the projector to rise, resulting in system lag. Please move away items that affect heat dissipation;
4. Please reset the projector, which will erase all of the data, accounts, documents and installed APPs;
5. If the methods above are useless, please contact the local after-sales service center.
