Gallery App on Android Crashes with Share

I had this problem: Every time I hit the share button anywhere using the Gallery app in Android, Gallery would crash. It made picture file manipulation quite difficult, and I just resorted to using other file managing apps. What an inconvenience!

When I searched for the answer I found this: http://inside-galaxy.blogspot.com/2013/12/samsung-galaxy-s3-how-to-fix-gallery.html.

It turns out that I had caused the problem, because in a flurry of turning off built-in apps, I turned off the "Paper Artist" app, which caused the crash on Gallery sharing.

When I Turned On the Paper Artist app, it fixed the problem.

Who would've thought that warning which stated "Turning off built-in apps may cause errors in other apps." would actually apply to anything?

Hope this is useful for anyone else with this issue.

My system for anyone who cares:
Software version: L900VPUCNE2
Hardware version: L900.09
Model number: SPH-L900
Android version: 4.4.2
Baseband version: L900VPUCNE2
Kernel version: 3.0.31-1561791, dpi@SWDD5716 #1
Build number: KOT49H.L900VPUCNE2
SE for Android statue: Enforcing, SEPF_SPH-L900_4.4.2_0016

Update (4/23/15): If the above strategy does not work, then you may want to check where your pictures are being saved and accessed.
I continued having problems with pictures on my phone, and the problem turned out to be a hardware one. The 64 GB microSD card I had installed was failing. I sent back the microSD card for a full refund, and bought a new 64 GB one (for cheaper, since the price has been dropping on memory!). Fixed a problem and made some cash, win-win.

Blurry 2560x1080 Display

I just got a SuperWide 21:9 monitor, and when I plugged it in via the DVI cable that was running my previous monitor, I was dismayed to find that on the highest resolution (2560x1080) the display was blurry. I was barely able to read text. After some searching for answers, I found one in an unlikely place. I discovered that it wasn't a software issue, but just a cable issue.

The DVI cable that was connecting my previous monitor was "single link DVI." I had to use the "dual link DVI" cable that came with the monitor. Same plug, just more pins.

Problem solved.

Hopefully anyone else with this same issue can find their answer solved here quickly without wandering.
