If your Samsung Galaxy A37 keeps taking out-of-focus shots, struggles to lock onto a subject, or produces photos that look soft even in good lighting, you’re not alone. Camera focus problems can come from a dirty lens, poor lighting, camera app glitches, motion, software bugs, or settings that make the phone choose the wrong focus point. The good news is, a few quick checks can usually bring the camera back to normal.

Clean the Camera Lens First
I’d start with the camera lens because this is the easiest thing to miss. Fingerprints, dust, oil, or a slightly smudged lens can make your photos look blurry even when the camera itself is working fine.
Use a clean microfiber cloth and gently wipe the rear camera lenses. Avoid using your shirt, tissue, or rough cloth because those can leave tiny scratches or more lint behind. After cleaning, open the Camera app and take a photo in bright light to see if the focus improves.
If your shots still look hazy, check whether your case or camera lens protector is partly covering the lens. Some third-party protectors can create glare, soften details, or interfere with focus.
Tap the Subject Before Taking the Shot
The Galaxy A37 can usually choose a focus point automatically, but it may not always pick the subject you want. This is especially common when you are taking pictures through glass, shooting a close-up, or capturing a scene with objects at different distances.
Open the Camera app, frame your subject, then tap directly on the part of the screen you want to keep sharp. Wait for the focus box to settle before pressing the shutter button.
If the phone keeps focusing on the background instead of the subject, step back slightly and try again. Some focus problems are really distance problems, especially when the camera is too close to the object.
Move to Better Lighting
Low light makes focus harder. When the scene is dim, the camera needs more time to detect edges, measure contrast, and lock onto the subject. That can make photos look soft, especially if your hand moves even a little.
Try taking the same photo near a window, outdoors, or under brighter indoor lighting. Hold the phone steady for a second before and after tapping the shutter.
If your photos mainly look poor indoors or at night, the issue may be related to lighting rather than a broken camera. You may also want to check this guide on why photos look blurry or soft on the Galaxy A37.
Restart the Camera App
Sometimes, the Camera app itself gets stuck. It may fail to focus properly, lag when switching lenses, or delay the preview after long use.
Close the Camera app from the Recent apps screen, then open it again. If that does not help, go to Settings > Apps > Camera > Force stop, then relaunch the app.
This refreshes the camera session without changing your files. It is a quick fix when focus problems start suddenly after recording a video, using portrait mode, or switching between camera modes too often.
Clear the Camera App Cache
The Camera app stores temporary files to help it open and process shots faster. But when those files become outdated or corrupted, you may notice lag, focus delays, or inconsistent image quality.
Go to Settings > Apps > Camera > Storage, then tap Clear cache. After that, restart your phone and test the camera again.
Do not tap Clear data unless you are fine with resetting camera settings. Clearing cache is the safer first step because it removes temporary files without deleting your photos or videos.
Reset the Camera Settings
If the focus problem started after changing camera modes, filters, aspect ratio, tracking autofocus, or advanced settings, resetting the Camera app can help. This brings the camera settings back to default without deleting your pictures.
Open the Camera app, tap the Settings icon, scroll down, then select Reset settings. Confirm the reset and take a few test shots afterward.
This is useful when the camera behaves strangely only in certain modes. It can also help if the app keeps using a setting that makes your photos look softer than expected.
Check for Heat or Performance Issues
Camera focus can suffer when the phone is hot or lagging. If the Galaxy A37 gets warm during normal use, the camera may slow down, take longer to process shots, or struggle when switching between lenses and modes.
Let the phone cool down for a few minutes, close background apps, then try the camera again. If you notice the phone heating up often, this guide on why the phone gets hot can help you narrow down the cause.
Performance issues can also affect the camera preview. If the phone stutters while opening apps or switching modes, check this related fix for lag in One UI.
Update Your Phone Software
Software bugs can affect camera processing, autofocus behavior, image sharpness, and app stability. If the camera focus problem appeared after an update, another patch may already be available to fix it.
Go to Settings > Software update > Download and install. If an update is available, install it, restart the phone, then test the camera again in bright light.
After major updates, your phone may also run extra background tasks for a while. That can affect battery, heat, and performance. If you noticed the issue after a One UI update, it may help to review possible post-update battery drain because heavy background activity can affect the whole device experience.
If your Galaxy A37 still has camera focus problems after these steps, test the camera in Safe Mode or compare it with another camera app. If every photo remains out of focus even in bright light, with a clean lens and default settings, the issue may be hardware-related. At that point, it is best to have the camera module checked by Samsung or an authorized repair center.
