bad lag and SD card not working properly

[mattyRrogers]

My tablet has been frequently lagging me off of games, no matter what game, and it's becoming a large annoyance for when I want to have some fun. Also my 32gb card doesn't work/ doesn't get recognised and won't let me add apps onto it that can. Any help would be appreciated.

if the memory card hasn't go any saved data on it Try formatting it its most likely corrupted

The lag from the tablet can be fixed a bit.
Go to settings and activate developer mode. Disable all animations and your tablet will fly.
For the card, the problem may be on the speed class. Try upgrading to a superior sd.

how do I activate developer mode

[Alyn89]

Go to settings, look for software information and also look for build number.
Tab repeatedly for 5 / 6 times, quite fast. You should get a pop up saying "you're 3 taps away from activating developer mode".
After, go back to settings and scroll all the way down and you'll see a new menu. Tap and scroll until you'll find the 3 options to change. Modify only those and exit completely without touching anything else. I'll send a picture.

You're welcome.
Please let me know if you managed.
If you did this, another option is to go to Galaxy store, search Galaxy lab's, open, in app install app booster.
It will clean and rearrange the software apps, improving speed up to 15%, but it may or not be available, depending on the version of the operating system.
