jay, 02 Jun 2016why j1 is slow despite a sd card 32 gbJust uninstall those apps you do not need, other than Google.
Click on the left key/button which is Recent app tray.
Remove all the active apps, in this way, it free more RAM.
I do this frequently and no issue, do give more RAM is run the next app.

It is for to secure you phone from any malware apps and unknown apps.
Unknown source; is to prevent malware apps from install, leave it as no check-mark.
Some apps will create problem for you, unless you fully know about the apps before install.
If anything are changed, it may lock the phone, ex your forget your password, after 3 attempt the phone will be lock.
This Samsung galaxy j1 is a piece of crap. And Samsung know it. Ive sent my phone back now three times,with exactly same problems as another person. Not able to access anything on it. Coming up emergency calls only. Optus dealer trying new simply cards. First time they said simply card reader was faulty and fixed. Lasted bout 10days and same problem happened. Last two time it was returned reckon no problem. Even though tech at optus said it's broken. Samsung don't want to take responsibility for putting out a pH that is useless. Mine is only 6mths old. Now in hands of fair trading. They will be fully investigated. I'm not letting this go. They need to do the right thing by people buying there phones. I'm glad they will be looked into. A multi million dollar company like Samsung should be ashamed of themselves

Wh... moreIn may opinion it is not a good phone (I think of the 20 or so I have had, this is at the end of the list), but some people have no issues at all. I have a Samsung J5 which is better if you can pay the different go for this. From day 1 I had issues, even after reset, restarts whatever I tried it had many problems (even with no other software installed).
My one keeps on spazzes out and whenever we try to send it out to Samsung, they just return it saying nothing's wrong with it! Not worth the money.
My phone switches the light on automatically and then cant shut off unless the phone is shut down and restarted. Runs the battery down if not seen that it switches on. How do I stop this from not happening?
