My iPhone is jailbroken and won't start up?

So yesterday, I jailbroke my device and started adding tweaks to it. And I've been using it the whole day; no problems at all. But just as I put my phone down and plugged it to its charger, it kept making the respring/rebooting noise. And since then its stuck at a dull apple logo and won't turn on?

Also it was working just fine before I left it to charge, the problems kinda started when I left it to charge. I have an iPhone 4S.

I think someone has jailbroken my phone and downloaded a spy software onto my iphone that also hides the cydia app. So basically I think my iphone is secretly jailbroken. I want to test if my iphone is really jailbroken by downloading an app that doesn't work if the iphone is jailbroken so if it still works it means my iphone is not jailbroken and if it doesn't work then it means my iphone is jailbroken

ik I asked this before but no1 answered me so i'm asking this again
