Ram

[King2828Dev]

Describe the bug.

It says for sum apps my flipper dont have enough ram... how so? Any way since some phone are able to turn memory (storage) into usable ram or pc flashdrives, is it possible to make it that so flipper zero uses sd card a part of it ( like 2 or 4 gb ram or how many it ever neeeds idk.. )? Anyway in short can someone tell if if it can be made and if you will make it into ur softweare cus i really like momentum its GREAT but that ram.. and when i open sum folders it takes time to load...

When you see an out-of-memory error, there should also be an option to reboot (by pressing the right arrow) which will free up all memory and allow the application to load. Some applications aren't perfect and may use memory even after they're closed (this is known as a "memory leak") and rebooting the Flipper frees that memory up again.

It is not possible to use the SD card for memory on the Flipper. For one thing, the SD card access is very slow as you've noticed, which is due to hardware limitations and is not possible to fix in software. The Flipper's processor also isn't capable of using the SD card as external memory, even if it was faster, and there's nothing that can be done in software to fix this.

I'll also add that, it's not that there isn't enough ram, flipper has enough ram, but currently not enough of that ram is free to launch that app. Ram gets used by stuff, and at the time of launching that app too much of it was already being used, as Aaron said likely by another app that used it without releasing it, or due to memory fragmentation (whereby there is enough memory but segmented in non-contiguous blocks and thus not usable to store the single large contiguous chunk necessary to launch the app)
