Go to calculator and type in .12345+= Do single test and then perform vibration tests. If one fails, go to service centre. But it sounds like you need to go service centre anyway.
Hi aru, Possibly a hardware issue, you can try the SMMI test steps shared by ronald above. Also, try factory reset once. Nothing works, Kindly visit the nearest service center: https://www.asus.com/in/support/service-center/india Due to the lockdown, service centers may not be functional. Kindly call the service center before you visit one.
