1. File browser > share > upload
2. [Network activity = 0MB/s] 5 Minutes from SSD>Phone eMMC NAND temp folder
3. [Network activity = 25MB/s] After 5 minutes, upload starts. Phone eMMC NAND temp folder > Cloud

Hope you could find what's on sda or sda35 that's using as a temp folder. G
Got the time to investigate nand usage and its 100% being used as a "middleman".
I have zero knowledge on where it might be, hope you can help us hunt it down so we can mount an ssd on it.
