To fix a tablet that is lagging and stuttering, you can try a few things that are listed below: Close unwanted apps from the background using the task manager. You should also remove data usage and location permissions from those apps that don't need to use data and location in the background. Uninstall buggy apps or apps that send you unnecessary push notifications. Try updating your tablet to the latest software update that's available by navigating to Settings > Software Update > Download and Install. If nothing solves the problem, you can try factory resetting the tablet. However, don't forget to back up important data from your tablet before performing a factory reset. You can also book Onsitego's tablet repair service and have an engineer come to inspect and fix your tablet.
