Please tell us some basic information before asking for help: Model Name: ZenFone 6 Firmware Version: Android 11 Rooted or not: No Frequency of Occurrence: Once APP Name & APP Version (If your issue relates to the app): In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc. ======================================== Today, my Zenfone 6 rebooted all of a sudden, then after a while all I got was a black screen. It had about an 80% charge the last time I checked, but just in case I charged it for an hour before attempting to turn it on again. Still nothing. I contacted Asus Support through chat and got quoted $85 (USD) for just the diagnostic (not including repair) since I bought this phone back in Oct 2019 and it is out of warranty. I suspect this might be a motherboard issue. Anyone know how much it would cost (in USD) to get this repaired through Asus?
