MicroSD read only OTA25?

[aimar]

I do not want to blame OTA25. I do not want to be a pain in the ass. I cannot corfirm OTA25 is the cause, but by the time I updated (BQ E4.5 stable) my microSD card started mounting automatically as a read only file system.
First I noticed the camera complaining about the impossibility of saving the pictures in the card. Afterwards I realized that Syncthing was not syncing and OSM ScoutServer also complained.
I shutdown, reboot, restart, detach the card and insert again without any luck.
Finally, this command in the terminal did the trick:

sudo mount --options remount,rw /dev/mmcblk1

/dev/mmcblk1 is the path to the card found by fdisk -l
Currently the issue is solved although I have to run the command each time I restart the device. Because now, I do not know why or how, I can boot without any trouble even with OTA25.
I would like to know how can I make this rw persistent.
Besides, does anybody have a similar issue since updating?

I realize that from time to time, maybe when the phone goes to sleep, the microSD card becomes read only again.
I use the mentioned command and I can create/delete again files in it.

It was quite annoying to open the terminal and launch the command each time I wanted to take a photo or save a file in the SD card, so I formated the SD card.
I have created symlinks for all the folders in the home folder towards the SD card. It is a 128 MB card, I have to take advantage of it.
However, although the problem is solved (the SD card is not read only now; I can write on it), the camera app keeps complaining stating that the SD card is read only. I removed the Pictures folder symlink and tried to save the photos on a fresh Pictures folder of the device's home folder. But every time I take a photo I get a "failed" error.
Has anyone faced a similar issue?

I have reälized that the Pictures folder I have just created in the home folder lacks the custom icon overlaying the folder icon.
Maybe that is the reason why the captures failed.
Even the screenshots are not saved (they do not however show any error alert).
I think camera app is not recognizing the /home/Pictures folder as valid.
Any ideas to solve it?
Thank you.

I found that the file ~/.config/user-dirs.dirs contains the default folders. So I edited it and restored the missing default home folders, e.g., XDG_PICTURES_DIR="$HOME/" to XDG_PICTURES_DIR="$HOME/Pictures".
Now I can save the photos in the device. The problem with the read only SD card persists. I have tried with a brand new SD card with no luck.

Well, actually I had not used "Pictures" but the translation to my language. It seems that for saving in the SD card, "Pictures" is mandatory.
Maybe I am wrong but at least now I can save wherever I want to.
