Son: What's an SD card, OTG cable and sharing device?
Dad: We don't know son, we are iPhone users

My phone fell down for the thousandth time and i thought it was okay as it usually has been in previous attempts at suicide.

Pressed power button ...
Screen turned on showing lock screen...
Touched back key .... phone vibrated....
Hmmm... It's okay. Didn't try unlocking screen...

Received a call later on....
Swiped to pick up call.... Nothing moved...
Turned the screen off. Turned it on again. Tried opening screen lock. Again nothing moved...

Got an OTG and plugged a mouse into phone.
Cursor moves.

Alas... My Phone's Touch Unit is DEAD :/

Hey here's a fun question!

If you plug an OTG enabled phone into a USB c MacBook who charges who?

😎😎🙃🙃😎😎

Why the hell did someone remove the wacom kernel module in android since 4.x? It wasn't hurting any body and instead gave people the ability to connect their wacom tablets to USB OTG compatible devices. As a result we have few apps that have wacom support in play store and shitty reputation that the rotten apple is better for all things media.

And for me it means I have to:
* Figure out a way to root my device
* locate correct version and configuration of currently running kernel.
* set up cross compilation toolchain
* build the kernel module
* transfer it to the device
* insmod it manually
* say a few prayers

.... All I wanted to do was paint 😢

Very excited, got my raspberry pi zero working over usb finally, gotta admit it took me a while to figure it out that the ifconfig IP assigned to the interface established isn't actually the raspberry pi's (seriously you don't want to see how far the visited google links go for all variations of "how to setup the otg ssh connection"), that only came to me once I was able to find the mini-hdmi to hdmi cable, before that it was a pure shitfest:

First I just tried all sort of configs, but the raspberry pi kept denying the ssh connection, slammed the microsd into my bigger Pi, even multiple times ran raspi-config, forced ssh to start in all possible ways, nothing.

Then I tried to use the TV-output on it together with my old small portable tv to maybe see some error-logs or the ssh not starting on the zero for whatever reason, even flashed a 2016 image thinking it is stretchs fault for not working, but then my fucking soldering iron cable disappeared, tried to quickly create my own, but that failed cause the 3.5mm connector it uses is different from the ones I had available, so I macgyvered a sketchy ass lose connection with male headers sticking through from the bottom and being sticked against the board with a female end on top, but the TV output wouldn't work, even with proper config options, so I gave up.

Some days later I've found the cable, connected it and realized the fucking IP it gets assigned is totally different from the interface, well fuck my life.

Atleast now I can make a clean image of that microSD and setup the portable laravel development raspi as I wanted, can't wait to try it once I get more time to fully set it up - btw even the internet bridge worked right out of the box, so I can easily use my laptops internet connection on the zero.

Wasted an hour figuring out why the backed up files and pics from an OTG device cant be seen on my laptop (linux)

Fucking OTG file system formatting is exFat. (i know i should get exfat-utils)

My first raspberry pi (zero W) came today and forgot to order OTG cables.

Looks like this thing is going headless.

Im thinking about getting a raspberry pi 3 or an odroid-c2.
(Specs at the end)

Its to host a simple php server and maybe a gitlab server, both for personal use.

Should I go with the better performance or the better community support?

My setup for plugging in my usb c phone to my usb a pc: two usb a male cables taped together and a usb otg adapter :)

It's 2023 and smartphone vendors' pre-installed file managers are slooooooowly beginning to catch up with the functionality that the third-party ES File Explorer already had in 2012.

Samsung's latest file manager "My Files" finally has a draggable scroll bar, background file transfer (one can browse files while a transfer is running), drag-to-select (which is still not nearly as fast as the instant A-to-B range selection of ES File Explorer which simulates shift+click selection on desktop), and even staying in the current directory after tapping on "Copy" or "Move" rather than going to the starting directory!

And finally, when copying or moving files to a MicroSD card or a USB-OTG device, files' date and time attributes are not discarded and reset to now, but the original date and time of the files are retained! ES File Explorer could do that with root access.

Dear Samsung, couldn't you have thought of these simple things a decade ago and saved your users lots of headaches?

Just found out that I can share power using USB OTG

The "recycle bin" feature of Samsung "My Files" is amazing for data loss prevention when moving files out of the smartphone.

There used to be two ways to move files out of the smartphone to make space free. One is direct moving, the other is copy-deletion. The first is self-explanatory, the second means first copying the files and then deleting them on the phone.

Thanks to the the recycle bin, which keeps data for a month, files on the phone can be copied out and then put into the recycle bin instead of immediately deleted.

This means that if the copying was incomplete, there is a thirty-day grace period to get the files back from the phone.

The benefit of moving files instead of copy-deleting them is the lack of the deletion step. Moving files out directly does not have the emotional barrier of deleting the files from source like the deletion step of copy-deleting does.

Moving files feels like moving items to a new room, where as the deletion step after copying feels like destroying something.

So why not move files out? Because there is a risk of data loss if the device disconnects while files are moved to an USB OTG device. Due to write buffering, files that are moved out might be deleted on the phone shortly before they are completely written on the USB-OTG.

This is not an issue with MTP (Windows or Linux through USB cable) because the file systems are managed by the computer, so if the phone disconnects while files are moved out of the phone using MTP, the file system is kept intact by Windows or Linux.

Now, thanks to the recycle bin, there is no emotional barrier to deletion because the files on the phone are automatically deleted after 30 days in the absence of the user. The user can press the "delete" button without worries because of knowing "I can get it back until a month from now anyway".

laravel websocket server, laravel echo plugins, android app, ionic angular frontend, laravel backend... hopefully the tech stack is stable for an ordering app
