The model number cited suggests a very low cost phone that was supplied "free" to members of certain plans. This may be similar to the "free" piece of junk I was shipped when the 2G networks in my area all turned to 4G. Yes, it was a 4G phone, but lacking MOST of the features I had PAID for a few years earlier. I never even powered it up; which is why I have a $69 (a day's wages, if I worked) BYOP Android that works mostly OK and takes good pictures.

The whole "cellphone" thing is amazing to me. When I was a boy, [Grumpy Old Man Mode]the phone was in the living room, or took a dime in the drug-store. Only Dick Tracy had a wrist-radio. The new transistor radios were AM only and 10X thicker than a cellfone. A camera was much bigger than that and it took weeks to get pictures back (but they DID focus, at 4 feet). A TV was as big as an arm-chair and $400 (OK you could get a BW small-screen with a handle for $99). Maps folded-out but never folded-back, and didn't tell you where you were. Mail-order was not one-click one-day gratification.[/Grumpy Old Man Mode]

My cheap phone just doesnt have focusing ability. and was poorly focused in the factory so all my pictures are blurry and not sharp.

Where can I find one to only focus with. something preferably that clips on.

Zoom and macro dont help. I want a non-zoomed scene to be in focus and clear. and not up close. just a foot to a few feet away. its blurry even on the sharpest "sharpness" setting.
You got a cheaper than cheap, a free phone ... what did you expect?

But fixed focus means that somehow, somewhere, the image will be in focus. That what was mentioned before in the description of hyperfocal distance. Just like the old Instamatic camera didn't have a focus control, just generally everything was in focus.
Thatīs exactly how "focus free" snapshot cameras and 99.999% of cell phone cameras work.
Your phone is not "out of focus" but simply crummy cheap ... did I say "free phoneĻ"

But if yours does not focus on anything at all, then it's defective. You'll either have to get it replaced, repaired or buy glasses for it.
Thatīs the whole point.

Actually we don't know that. His camera may well be out of focus, a bad lens. We have not see any photos from it to verify. If it's always badly focused, then it's defective. Even cheap cameras are in focus for most subjects.

Its only out of focus around two feet or less. but thats still lame and theres no way anyone could usably take a "selfie" on this phone at all. would look horrible unless you had super bright studio lighting or something at the perfect angle

if I have the sharpness option on minimum it looks REALLY blurry
on medium its "not good but not bad but still looks "slightly out of focus" on maximum sharpness it looks like too much contrast around edges and not good.

I have a USB microsoft 1000 webcam with manual focus and I can focus that sucker so good it puts my phones camera's focus at 1 to 3 feet put to shame. and its at only 640x480 resolution capability
while my phone takes pics of up to 1600x1200 and still focuses worse around 1 to 3 feet

And thats with NO zoom level.

my phone has bluetooth and wifi but I rarely use it for that even. and i rarely actually use my phone anyways. I'm on my computer nearly 100% of the time.

> around two feet or less.

2 feet: "+1.5 readers"
1 foot: "+3 readers"

This is JUST like the old fixed-focus Kodaks. Focus was 4 feet. f/stop was small so depth of field ran out to infinity good-enough and in to almost 2 feet, no closer.

Does that mean it is in focus at all distances longer than 2feet?

Then it will take a selfie if you hold the camera at a distance longer than 2feet.
and it will allow pictures at much longer distances.

If you need focus closer than 2feet then you need to add on a close up lens (+dioptre)
You can buy dioptre in 1/4 steps.
0.25dioptre changes an infinite focus to 4m (= 1/0.25)
0.5dioptre changes an infinite focus to 2m (= 1/0.5)

If the camera is already in focus at 10m but slightly out of focus at other distances, then you can think of the lens as being at infinity with a +0.1dioptre close up lens added.
This 10m focus camera with a +0.25dioptre close up added will behave like an infinity focus + (+0.1 +0.25) = +0.35dioptre.
This will focus at 1/0.35 = 2.86m instead of @ 10m

Then it is working fine,like any and all other fixed focus cameras.
What did you expect?

it will work very well taking "normal", say waist to head selfies, from 2 ft away or more.
Now if you want to, say, your nose to fill the frame, then you will need close up or macro lenses ... like on any other camera.

define "horrible"
now we drifted from a Tech problem to a "taste" one.

Digital post processing can improve a poor image but Magic is out of the question.

There. You answered your own question.

It would be very unrealistic to expect otherwise.

I noticed that.

Which means that you donīt actually NEED your phone at all
Just plug that HP USB ***manual focus*** camera into your computer and take all well focused selfies you want, zooming in on details as you wish.

if I were to hold it at arms length and take a pic. it would be blurry not only because its slightly out of focus still at that range but also because the slow exposure
if the phone is moving even a tiny bit it gets super blurry.
You have to have it sitting against a block of concrete or something that doesnt pick up any vibrations to get rid of that exposure blur!
Or a tripod at least
but I dont have a tripod

nearly 100% of everyone elses phones even fixed focus still focus much better at 0 to 2 feet

if I were to have just my face from my neck up in view when taking a picture it would be blurry from being out of focus slightly.

I'm not talking about just my nose being in view
You literally cant take a good selfie or anything for example. its just crappily out of focus anywhere closer than about 2 feet!

And even past 2 feet it only gets a smidge better and not really anymore. You need to turn the sharpness setting waaay up to get things to appear to be in focus anywhere near 2 feet
