Re: [Trisquel-users] Is Google the biggest, most successful proprietary software company ever?

I have an Android 5.1 phone without any SIM card installed in it. I don't use  
the WI-FI and it is left continuously in flight mode. Nevertheless, it is  
possible to dial an emergency number with it. I use it only for note-taking  
using an .apk app, pdf reading using pocketbook, taking pictures and  
occasionally obtaining GPS coordinates with GPS test. I am almost certain  
that because of this, I am not able to write files to it after successfully  
mounting it using sudo mtpfs -o allow_other, I only see files, read them but  
not write, except on one single occasion, after failed repeated attempts, was  
able to copy a .pdf to the built-in SD card where the Android filesystem is  
configured for all user data. What baffles me is that from the bash terminal  
the sudo cp is invoked and without complaining leaves the the destination  
untouched. I can create directories but can't copy files! Using the usb otg  
cable, I can copy files in or out to a flash or removable hard drive using  
the Android File Manager, but at the expense of losing original file  
date-time attributes. Has anyone tried this also?
