Cannot get camera to focus - Walmart Onn Tablets General

I have the 8" tablet 2019 model and I'm trying to scan barcodes with the MyFitnessPal app
I cannot get the camera to focus on the barcode at all. I've tried moving it closer and farther but it just won't recognize it.
Any ideas how I can improve the camera focus?

How to setup camera for barcode scanning?

I am trying to get my focus to utilize the shop savvy app, but it doesn't take as good of close ups as my TP2, is there a setting or anything I need to change. Thanks in advanced.
When you fire up the camera, go into settings. Click "AF Mode", and choose "Macro". That should do the trick.
The other thing is to experiment with the flash off, or shoot at a slight angle to minimize glare.
Unfortunately, as you probably know, the camera settings always revert back to the defaults every time you exit the camera. That's one of the common complaints we're all hoping will be fixed by a software update.
Brad.
thanks I will try that, trying at work no luck as of yet. Have you tried the app shopsavvy yet?
Shop Savvy and BarCode pics
I'm using it, and it usually takes a couple of tries before I get a good picture that's recognizable. Have not tried the Macro setting, but I have noticed that the focus beep must sound before I snap for the picture or else I get gobblygook.
Microsoft Tag app is garbage.. I tired for an hour to scan in 10 diffrent tags. Changing camera settings for AF mode, lighting, etc. etc. Even they admit they need to make it use the video mode to line up the tag to scan. Until they fix it, it's a mediocre app at best
Hold the camera button half way down - picture will focus on bar code - then depress and you should have proper result.

This along with turning the flash off works like a charm. I have been going around the house snapping all my bar code labels. It works surprisingly well. Thanks
I have scanned a few barcodes and it worked for me. The main things is to turn off the Flash, and use the half press on the camera to focus properly. Then once it beeps snap the picture. I never switch to Macro mode and the half press takes perfect closeups.

Camera blurry problem

My nexus 6p is now about 1 month old and since yesterday i noticed my rear camera has been producing unfocused and blurry images. It also make a little cracking noise when i open the camera app or switch back to the rear camera from the front facing camera. Please help me please. I tried to clean the lens and I even buy fv camera 5 and try manual focus but it did not work. The images produces from the rear camera are now even worse than the front facing camera.

From what you describe it sounds like the VCM/AF Actuator has malfunctioned.
Try this Download Freedcam from play store
Make sure you give it permission to access camera
Settings > Api > Camera 2
Then set Focus to manual then activate Focus Peak
Then move focus wheel if you start seeing yellow higlights/ outline that means its focusing if no highlights then AF Broken.
Also try Reset Device if no go i suggest you return the device

I tried to reset but it did not work also I tried moving the wheel but no luck. I ship this unit to Vietnam which is where I'm currently living so I cannot send it back. Also the cracking noise every time I open my main camera really worried me, it does sound like something went wrong from the inside. I have been taking fine and focused image up till now. I find this happened the day after I went home raining without an umbrella or raincoat. It was a small rain and the device was not soaked in water it was just having little splash of water on it. I wondered if this was the reason
After I googled this problem there seems to be others having the same problem as me and they are sending back their devices
Hi koala . Did you send back yours too? I bought this phone about 5months back. I have the same problem. Any chance of a replacement?
Hi, Did this ever get resolved? I ordered a replacement camera module and tools to fix it myself. The repair guide is from Repair Universe. Here's the video on YouTube.

Did you update to Nougat already? I do not experience this, but it might be because I'm still on Marshmallow.

What is wrong with S8 front camera autofocus

Hello. I am new owner of S8. As they claim front camera now has autofocus so selfies will be now "sharper" .
I dont know if I just have wrong model but when I am doing selfies really close to front camera they are really sharp.
However if I move camera little bit further it start re-focusing almost all the time. If I touch on the object sometimes it helps a little bit but it still not good.
The best result I could achive, you can see on the photo (and I tried many times and others were even worse). The text is totally unreadble. It is same with faces, but you can see it better on text.
I compared it to much cheaper phone Honor 8, which does much sharper photo without any autofocus.
Does any of you have the problem, or it is just me?
I tried restore camera setting but it didnt help.
Thanks for feedback. (cause I have no feedback from samsung )
I got the s8 plus and for me the front camera is beast! I know back on the s7 the camera was eh and the keyboard lag was real so I got the edge. It could be the camera or you could be snapping the camera too fast. Takes a sec to grab the image.
Do you have selective focus on? This mode will blur background to simulate portrait mode with telephoto lens on DSLR. I find it useless, but stupid iphone has it so why not galaxy?
Mine is not 100% sharp either (however much better than yours), but I have low light now and get shutter speed of 1/24sec, it's hard to hand held photo at 1/24sec without some shake. Need to retest this in full sun tomorrow.

Hi, no I dont. And this is another problem. When I try to do picture in this mode it always say me something like "Picture was taken but the effect of contrast cannot be used because no object was reckognized" . So there must be something defenetly wrong.
And when I was doing photo I was waiting more than 5 secs to focus but the result was still same. And I put phone on the table so I didnt move with it at all.

Thats sounds similar to message I got when using selective focus. It tells you that it couldn't recognize your face so the effect wasn't fully applied (in selective focus that effect is to keep sharp focus on face and blur everything else). Seems like you have some effect enabled and that could be your problem. I never got any msg, except for selective focus, but didn't have much time to play a lot.

I tried factory reset as a last option and it still didnt helped. I reviewed lot of videos and pictures of S8 online and for sure mine is behaving different. Probably I will have to take my S8 to the nearest service..
Sounds like you do have a problem. I used my S8 and stood back and the picture was focused. Closer ones have always been focused.
I had the same issue, but really don't know If what I did was the fix, because this issue was happening every time I open the camera app after a while (like half an hour) and I had to knock my phone just to wake up my focusing sensor or what ever it called, but after I:
- re-enabled all the disabled bixby apps.
- stopped using my car magnet holder - so it never gets too cold because of the car's AC and never gets attached to a magnet.
after that, camera never miss-focusing anymore, now more than 3 hours.
So please, if anyone had this issue and:
- not using any magnet holder.
- not disabling bixby apps.
- not having the phone too cold.
please tell us to be aware.
I know it's not logic, as long as I can use the camera normally after I knock the phone, so it might be a hardware problem, but I'm sharing my experience with you just to find out the fix.
Thanks
Update: Nothing from the above was the issue, still; miss focusing, even after a factory reset... waiting for July update and see if they will fix it.
Hey there, I too have an issue in front camera of my galaxy s8 when I put it too far then it shows blurry image but when the camera is nearby the object then it shows some good quality, but not showing as much good as it was showing before .
i have the same issue. But the camera works when it wants to work... but sometimes is blury (most of times)

S10+ camera focus issue

I recently got the new Samsung S10+ 1TB phone and every time I take a picture, the photo comes out blurry or out of focus, even when the object isn't moving. I have even restarted my phone as a Samsung technician recommended. I have also installed the Google Pixel camera app from another post and that has less issues. Any one found a fix or have the same issues with the native camera program in the Samsung S10+?
Which application installed ? all work for me is not stable(((
I have Exynos 9820
Stock. I didnt chang anything. I ended up download gcam and open cam. They have no issues.
Native camera doesn't appear to focus all the time on my S10+, but that's just one issue. My scanner rarely works. I'm gonna ask if BB can exchange mine...
For the finger scanner i rotated my finger around at strange angles and it works great for me.
Same
I am having this issue with the front facing camera.
9 out of 10 times I try to take a selfie or use face unlock, the front camera won't focus.
The only quick solution I have found is to tap on the lens glass once or twice. After that the camera will work correctly, but only for a short while, after which I have to repeat tapping in the front camera glass.
I'm guessing the camera module is defective.
I can't get my S10+ that I bought straight from AT&T to focus on close up things at random times when I need to take a pic of like a nail or something. Not sure the S10 has it, but there used to be a macro mode on the S3 and S4 that made this a lot easier.

Poor focus in live focus mode - Can someone please see if you can replicate?

S10+ UK variant with the latest updates installed. I have an issue with the camera. If I open the camera and choose Live Focus, the default lens is the one with the single leaf on it, which is the lens that makes everything the biggest/closest etc. If I hold my hand or anything else out in front of me, the camera will not focus on my hand/object at all. If I wave it about, it will sometimes come into focus momentarily, but will not focus as you would expect, the image is also quite poor. If I then change lenses to the other available one, which is the one with two leaves on, that focuses perfectly and very quickly and is nice and sharp in the areas that I choose.
Samsung said to factory reset and I did and it did not fix it. They also said that Tracking AF setting should be enabled, but it is greyed out and there is no way to change it. I found a video on youtube on how to enable it, by reducing the resolution of video recording for the rear camera, but as I'd just factory reset, it was already on a low setting.
Also, all 3 lenses will focus as they should in auto and pro modes, just not live focus.
Could anyone please try this for me?
Open camera->Select Live Focus->Select the lens with the single leaf icon->Hold hand or other object about 12 inches/30cm away. Does it focus properly?
Also, with the camera still open->settings->Tracking AF <--is this greyed out?
Thanks, any help, much appreciated.
Same with me. Never noticed before as usually nor use live focus mode.

For me the 2x zoom camera(single leaf) has problems of focusing when I shoot a video. Try that also and see if you guys have the same problem

Thanks. Yes, mine is the same. I had mine set to 1920 @60fps and there's no option to change lenses, but after setting it to just FHD 1920x1080, the 3 lenses are available. The focus here, although not working as expected is better than it is using live focus.

I am using 4k 30fps, and for me sometimes the focus for the telephoto(x2) struggles to get perfect. Maybe is a software thing that will be corrected. Also checked it and the tracking AF is also greyed out for me.
