Will a photo on my Samsung Galaxy s4 turn into a real photo clear enough to frame and hang on a wall ?

Don't know about the S4 but my S6 has produced some photos good enough to enlarge to 10x8.

The S4 has got more megapixels than most people are ever likely to need. (13Mp). It's hard to tell the difference between an image taken on a (decent) 2Mp camera and a 4Mp one when enlarged to A4 size. Unless you're seeking bigger prints, additional megapixels are entirely pointless.
However trying to cram a vast number of megapixels onto a tiny image sensor isn't generally seen as a good idea, as it can end up with lower image quality. The S4's sensor isn't really up to the job; it's simply too small.
Further, irrespective of how many megapixels you've got, or how big the image sensor is, final image quality is largely down to the quality of your lens. The tiny lens on any phone will never be as good as the lens on an a DSLR camera (which, at professional level, might cost many thousands of pounds).
Further still, the tiny lenses on mobile phones only let in a small amount of light. That precludes the use of fast shutter speeds, which are needed (particularly in low light) to 'freeze' fast-moving objects or simply to avoid 'camera shake'.
Mobile phones try to ensure that everything within the field of vision is in focus. (That's actually hard to avoid with such a tiny image sensor anyway). So you've got no control over 'depth of field', which is essential if you want the best pictures in many situations.
If you're taking, say, a picture of a beautiful bay on a bright sunny day (i.e. where there's plenty of light and you want everything in the shot to be in focus) you can get a good picture from most mobile phone cameras. However if you want, say, a portrait shot of your grandchildren, taken on a cloudy day (so that there's not a lot of light and where you'll want the background to be out of focus, so that the viewer's eye is drawn to the kids, instead of to your rusty lawnmower in the background) you simply can't get a really good photo from a mobile phone.
To guarantee the best possible quality (or, at least, close to it) you should always use at least a 'high-end' compact digital camera (or, better still, a 'bridge' camera). They don't necessarily cost a great deal. (I got my grandson a decent quality bridge camera for his 11th birthday for under £100). For 'professional level' photographs you should expect to spend at least £2000 on a decent DSLR and the lenses to go with it.
