Ghost apps? Symbolic views that just won't go away.
Hi, I'm having an issue where sometimes deleted apps just decide to leave behind a 'symbolic view' that never goes away no matter how many times I delete it or reset my Prime. The issue is specifically a problem with deleted PDFs and Flappy Bird. All of which I deleted several months ago but their symbolic views keep popping back up in the apps menu every couple days. I'm currently running the latest beta on my G2, however this was also an issue on the previous OS.

I'd appreciate it if someone could explain what's going on and how I can permanently get rid of the apps!

RE: Ghost apps? Symbolic views that just won't go away.
G2 machines (HW rev D) have been exhibiting this behavior for over a year now, and still are, with beta FW rev 14284 installed. Example:

(1) Save any app using any name you like.
(2) Toggle power, to save everything to flash.
(3) Delete the copied app you saved.
(4) Toggle power, to ensure no RAM ghosts are present.
(5) Perform an On+Symb warmstart (or a paperclip warmstart).
--> Your saved app will reappear (as well as all previously deleted apps).

This does not seem to happen with G1 machines (HW rev A or C) with the most recent beta FW installed (rev 14298).

Hmm... I just noticed that G2 machines revive these ghost apps not only by warmstarts, but even by putting the G2 into coma mode by pressing Shift down, holding it down, and pressing On for one full second before releasing both. When the G2 reawakens from coma mode (it takes a few seconds after pressing On), the ghost apps will have reappeared. The OP's experience seems to indicate that this can happen even if the coma mode was initiated by the calculator itself (which it does after several days of inactivity).

Any other insights regarding this phenomenon of ghost apps would be greatly appreciated.

*bump* Is there any more information people would like to add? Joe Horn's steps perfectly reproduced my issue. Is a bug fix being looked into?

I have it captured. Seemed like might be a filesystem caching thing going on possibly???
