- Samsung Galaxy S Relay
- Android 4.4.4
- Cyanogenmod 11
I've tried many different solutions to sync my phone's SD cards with a computer over Wi-Fi, leaving them to run overnight because there's so much data (~30 GB), but in the morning the phone is slow and unresponsive, warm to the touch, apps like Gentle Alarm don't work, etc. It becomes so slow that when I try to use it, it eventually stops responding completely and reboots itself. I've tried:
- FolderSync
- Syncthing
- Samba on phone
- FTP server on phone
- SSHDroid on phone and SyncBack on computer
- iDrive Backup
At first I assumed it was because the apps were flawed, so I tried different solutions, but since it happens with all of them, it seems it's a more fundamental OS problem, like accessing too many files at a time or sending too much data over the network causes the phone to become unstable? Maybe a memory leak or it opens files and never closes them or something? How can I diagnose this and make it workable? When I look at CPU/memory usage, it seems normal? (Though it reboots while I'm trying to check, so a CPU/memory usage logger would be better.)
