[Q] USB OTG mount problem

[soralz]

HI guys, I am very satisfied with this phone when I got it a week ago. However, I was facing sometimes my phone unable to mount USB OTG storage, I mean the USB drive won't lit at all / detect by phone, I have to reboot the phone then it only gets detected. Any other way round to solve this without rebooting?

I haven't had trouble using my OTG usb stick so far. Have you tried using Nexus Media Importer? It lets you mount/unmount on demand.

Does it show the USB drive as unmounted in the Storage menu?
Also, did you try a different thumb drive with a different filesystem on it? I cannot reproduce your issue at all.

Ok after my investigation, the USB OTG still works but just the USB port of my phone unable to supply power, if I use a power bank + USB hub then connect to my phone, my phone detects the USB drive. Similar to somewhat my phone requires external power to mount. But if I reboot my phone then the USB OTG work properly again though. Until I remove and remount it next time, then the problem occur again.

Currently my phone setup as my signature. No custom kernel but just recovery.

Ok I know whats the problem now. You can try during deep sleep insert in your USB OTG. It can't detect at all even if you remove and reinsert. Have to reboot the phone. So my guess is right I think. The phone have to screen on to insert USB OTG or else it cannot detect.

Did any one try a 1tb portable hard drive?

I don't have 1TB but I have 500GB and it works without external power.

I don't have 1TB but I have 500GB and it works without external power.

few older phones supported 500gig portable hard drive too but did not support 1tb, my phone will be delivered tomorrow I'll update here then.
Fingers crossed.

I just tried a 16GB USB drive through an OTG cable, and it didn't detect it. My screen was on, and I was running stickmount as well.

I had to restart the phone to get it to detect.

I have the same issue with my N8010. Have to restart to get it to recognise the USB.

Hopefully, there will be a simple solution to this.

Well it seems in my case it's rather random, sometimes USB drives (or HDD's) will mount, other times nothing happens at all, while some drives refuse to mount at all.
Maybe it's faulty cable don't know?
