If you have time to go through some old messages in the Rog 5 forum, you can view thousands of threads reporting the same issue as you said. I have replaced the motherboard twice on my Rog 5. At first, I encountered persistent issues with my ROG 5 (8/128), specifically related to Wi-Fi and hotspot connectivity after 5 months of purchase. To address these problems, I submitted my device to the service center for repair. The motherboard replacement took approximately 36 days to complete, during which my phone was in service. This extended downtime was certainly inconvenient. However, the real shock came when, just few months after the initial motherboard replacement, my phone became completely dead. This occurred shortly after the warranty had expired.
Upon contacting the service center, I was informed that I would need to pay a hefty sum of 48,000 INR for another motherboard replacement. This amount was equivalent to the cost of a new phone! and understandably, I was reluctant to proceed with this expense.
In response, I escalated the issue by reaching out to ASUS officials through numerous emails. After persistent communication and outlining the recurring nature of the motherboard problem, ASUS finally agreed to replace the motherboard under a one-time warranty extension. This time also the phone was in the service centre for about 40-50 days.
Due to the recurrent issues and my concerns about the motherboard's reliability, I never played a single game since then using my ROG 5, so called gaming phone fearing that it might cause further damage to the motherboard.
