The exact cause of the issue is unclear, but it appears to be linked to the device’s motherboard. This incident follows previous complaints about lagging and overheating issues in various models. OnePlus has encouraged affected users to contact customer service, but the new problems suggest that motherboard issues remain unresolved. The company has not yet commented on the situation.
