When the Redmi Pad SE 8.7 4G lags during the first boot or after an OTA upgrade, it's due to the system handling numerous tasks simultaneously. The initial setup process, including data migration and optimization, places a high load on the device, which can cause temporary slowdowns. This is a common occurrence in Android devices as they configure new settings and applications. It's recommended to wait at least 3 minutes for the system to complete these tasks, including the setup guides.
