Why can't I take pictures and keep apps open?

[AC Question]

Android 4.1.2 model U671C

I've cleared everything I could possibly clear and I've tried everything. I'm an artist and I bought this phone so I could share my art more efficiently but now I can't even take pictures. I can't keep apps open for long and I've had to delete many apps just to have Facebook Messenger open long enough to send one message at a time.

The cache has been cleared on everything multiple times, I've run many virus scans and nothing seems to be wrong with it, all the apps I don't use (even a few I do use) have been cleared, deleted, or disabled. No matter what I do, the phone is still not working like it should.

I don't use data or anything, just Wifi. I know Tracfones aren't always the best but it shouldn't be having any problems at all since it's new.

Please help me, thank you.

Welcome to Android Central! Can you clarify -- what do you mean that you can't keep apps open for long? Do they automatically exit? Or do they crash and give you an error message? Are you saying this is directly related to being unable to take pictures?

They automatically exit, no error message. I don't know if it's related or not, I was just stating all that is wrong with my phone.

The only app that has an error message is the gallery. There really shouldn't be anything wrong with this phone and I'm very frustrated with it.

Are any power-saving modes turned on, or 3rd party battery-saver apps? Or "RAM cleaner/booster" apps? If so, get rid of them.
