Default Finding a manual focus adapter for a fixed focus phone camera?

Trying to find on on amazon.. All I can find is telescoping zoom adapters. and macro adapters. and wide angle adapters.
But none that simply let you manually focus! I dont want to zoom! Just focus!
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.

Reading glasses. $1 at Dollar Tree, $3 at Dollar General, $16 at RiteAid. Or in the crack in old folks' couches.

"Fixed focus" cameras are focused for near infinity. A "+1" reading lens will make near 40 inches. A "+2" 20 inches, "+3" 13 inches.

Magnifying lenses are rated different. A "5X" makes infinity happen near 2 inches, a "10X" makes about 1 inch. Tape the lens to the camera and adjust subject-camera distance for focus.

Or just get a less-junk camera. I am very pleased with a $69 Android phone.

I dont want to zoom. just adjust the focus seperately.
Like a lens that only changes the focus.
Where can I get that?? Please?

Also my phone was a free ZTE QLINK wireless type phone. (obama phone basically)
Its very basic and featureless. No flash option no front camera. and fixed focus camera.
Not the best quality camera because its out of focus and somewhat blurry.

The reading glass trick isn't a zoom. It's' worth trying some different magnification to see if it helps. Just go to the drug store and shoot a few photos thru them.

My mildprescription for distance viewing is the opposite, like a wide view mirror. It makes things slightly smaller, but much clearer.

The reading glass suggestion does *exactly* that and nothing else.

If you want to continuously adjust focus by hand, at will, then you must dismount the current lens in your phone , make a helical adjustable mount (vulgo: fine pitch thread which lets you continuously adjust lens-to-sensor distance) which is what realcameras do.

IF lens is separated from sensor (or film) by its own focal length, then camera is focused at infinity (scenery pictures), IF twice focal length then itīs at an extreme Macro setting where object and image are same size (1:1) ; any setting in between will cover the full range of any adjustable focus camera and then some.

If you know a skilled mechanic, preferrably somebody used to work on clocks and such, he will be able to make such a custom adjustable mount for you.

Then you will have to try corrective lenses, just like with eyes.
I can't think you'll find the attachment you are looking for, as all cameras are supposed to be focused on something. Why would there be an attachment for a function that's built in?
Is it possible to go to the place where you got the phone and check it against another of the same model? See if another will focus correctly.

No I checked the model already and it simply does not support focusing ability.
Doesnt even have the physical ability to focus the camera. It is literally just put together.

ZTE Qlink wireless phone very basic model with limited features. No flash.

Camera app doesnt have any focus ability either. and seems like a really stripped down simplified version..

tried a camera app that I know does have focus ability. but it did not become active when i installed it. The option was "not there" where it should be.

SO i'm pretty sure its a fixed focus camera. Which really stinks.

I didnt "get" the phone from a place.. Unless you count my mailbox. because it came for free in the mail.. its a free android phone. You get what you pay for.. Which means barely diddly squat..

Yes, that's understood. 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.

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.
