Android doesn't seem to support external touchpad (usb or wireless) pinch gesture for zooming in and out? I tried a few external wireless keyboards with touchpads built-in, while the touchpad works for pinch on Mac and Windows, it didn't work for pinch-zooming on Android. So my guess it's not possible. I use my Android TV box (BuzzTV box, Android 9) as an Android desktop for apps e.g. PDF reader. Also tried using normal mouse, scroll wheel and ALT or CTRL or whatever combination it is typically.. I understand Android 14 has support for external keyboards but I don't see mentioned whether it also provides pinch zoom gestures for external touchpads. Not planning to upgrade the TV box yet. To solve the external keyboard compatibility, there is an app called External Keyboard Helper for Android. That solves the keyboard issue. But I can't find anything similar that would allow me to use pinch/zoom on external touchpad. Some apps have support for keyboard shortcuts (Alt+leftButton+arrowRight/arrowLeft works for me), but most apps do not support this. The issue is not related to this specific tv box. I tried other brands TV boxes and it is the same problem. Is it a universal Android limitation? UPDATE: Here I found some answer.. But I am still looking for a way to pinch zoom a PDF. So I guess my question needs to be - is there any app for PDF that supports pinch and zoom natively on non-touchscreen pointing interfaces? https://android.stackexchange.com/questions/82062/how-to-pinch-zoom-on-device-with-no-touchscreen-like-an-android-stick

Although a software developer, I'm asking this as an end user. Some mobile browsers automatically zoom in when a text input element is focused; I think this happens when the font size is ` tag techniques [here](https://stackoverflow.com/questions/4472891/how-can-i-disable-zoom-on-a-mobile-web-page) , but they don't seem to be supported anymore. This is especially necessary on a tablet. Although it's technically a mobile device, my tablet screen is as big as a laptop's, and zooming is completely unnecessary.

I do some of my works using browser in Desktop Mode. But on every browser I tried, when I click on an input field on the website while in the desktop mode of the browser, it zooms automatically, which makes me not able to do my intended work easily. Is there any browser or browser settings to disable it.

I am not sure I am using the proper terms, therefore I will exemplify them with screenshots. *Please help me improve my terminology if I am wrong.* (I'm not sure https://android.stackexchange.com/q/59717/161921 is about the same topic, as I don't grasp the meaning of terms like " viewport metatag parameters user-scalable" and "meta viewport tag".) --- Taking a Wikipedia page: Simply **zooming** it - whether with forced zoom enabled or not - would give this (like in Chrome), where the font size appears larger but the text body is not seen in its entirety, as it **doesn't fit the screen**: while what I would like to see would be this - what I call text fit or text wrap, where **the font is enlarged without losing the entirety of the text body**, which in this case **fits the screen**: --- I know this is available in Opera. I would like to know what other browsers have this feature.

On most web sites, when I look at them with Chrome on my phone (a Nexus 4 running stock Android 4.2.2), I can adjust the font size by double-tapping a column of text to make it widen to fill the screen. However, this doesn't work on Wikipedia.org; I don't know why -- the text is quite small. I've already got the browser set up to display (very) large fonts: I'd gone to "settings", "Accessibility", and have cranked the "Text scaling" slider over to 155%, which is ginormous. (There's also a check in the box that says "Force Enable Zoom", which I don't recall setting; I guess that's the default). Anyway: this feature works fine on most sites, just not Wikipedia (and perhaps a few others). Any advice for making Wikipedia readable?

The following happens in various applications such as more than one type of web browser and Adobe's PDF reader. I'm scrolling through text at a comfortable zoom level, and then suddenly, I touch the screen the wrong way, and it zooms way out. How can we prevent this UI behavior?

I have a TV that runs Android 2.2. It can take a USB mouse and keyboard, and I'm running the Dolphin web browser on an auto-refreshed page for digital signage. Only thing is, I can't get it to zoom in or out - there is no touch (so multitouch doesn't work) and there are no +/- buttons as there are on some stock browsers. The stock browser doesn't work on the site in questions, and Firefox won't load onto the device (it has a MIPS processor, so any app using the native SDK won't work). Any ideas?

*Android 11; Samsung Galaxy A20 (SM-S205G)* --------------------- I've had a long-standing problem on my Android phone with *IBM Community forum websites*. Forum postings like this one are zoomed in too far. I can't read the text on either side of the page (portrait or landscape). I have the same problem in all browsers that I've tried. I've tried pinching out the screen to zoom out, but that doesn't do anything. It stays at the same zoom level. - - - My uneducated guess would be that the page isn't handling responsive design properly. I've reported the problem to IBM. But they don't seem to be interested in fixing it. I don't have this problem with any other websites on my Android phone. For example, there are even other IBM forums that don't have this problem . But unfortunately, I don't use those specific forums. --------------- I've had some luck solving the issue on a different device: Safari/iPad (7th gen; 17.7.1). In Safari, there is an option where I can zoom out at a set percentage (85%). There's a tiny bit of cutoff at the righthand side. But I can live with that. -------------------- **Question:** To compensate for the problem with the IBM website on my phone, is there a way for me to change the zoom level in an Android browser app? (just like I did with Safari?) So far, I haven't found a setting like that in Samsung Internet, Firefox, or Chrome. I'm open to installing a different browser on my phone if needed.

In there a way to get the effect of (zoom out/pinch put)/in with external mouse and or/keyboard? For games like angry birds or using google earth.

When I use apps like Discord, Facebook Messenger, Zoom, and Google Meets to call people, it compresses the audio like it would in a normal phone call, even though using those same apps from the desktop give much better audio. How do I go about making this audio sound better and not so compressed? I'm using a Pixel 3 XL and am on AT&T (although most of the calls happen over Wi-Fi so I don't see how that matters).

I have a Huawei P30 Pro and this Bluetooth camera shutter. The shutter had dedicated buttons for zooming. Sadly, the volume buttons on the P30 just act as a shutter (the zooming buttons on the shutter just send the volume buttons signals too) and there is no customization option in the built-in mobile app to set them for zooming). I found [Adobe Lightroom ](https://play.google.com/store/search?q=lightroom&c=apps&hl=en_US) that lets you use the volume buttons for zooming, but it does not utilise the optical zooming of the phone and the shutter button will stop working (it will be similar to the zooming-out button) Is there any workaround? Alternatively, any apps that can be installed to take photos instead of the factory app?

Any way to simply turn off the cell phone radio? This need has come up in ZOOM sessions using the zoom app because that app uses the "phone audio" rather than "media audio" As a result, it is impossible to include meeting audio if you ChromeCast the session. The video works, but the audio only outputs using the phone's speaker or audio jack. Testing using an android tablet rather than an android phone shows that since the tablet does not have a cellular radio, the meeting audio is cast with the video. Airplane mode is not an option since that would prevent connecting to the internet. In addition, trying to address the audio using a bluetooth speaker doesn't work either... while it's possible to initially send bluetooth audio to the speaker, something unknown turns that off after a few minutes. Any thoughts on addressing this would be appreciated. Beverly Howard

Hey guys am running Android x86 9.0 r2 on my pc and its running great, i am playing clash of clans on it and it works great but i can't zoom out as we do on phone as pinch like with two fingers, I don't have touch screen am looking for a way to do this as bases are wide its hard to move through mouse so looking for zoom as second of time waste to move in base with mouse ruin my raids following are things i tried :- 1. I tried a app called assertive touch still no success. 2. I tried all shortcut keys found on Google search like double click then hold and move up mouse or move down. but none of work if anyone knows something let me know and be safe.

I am looking for an app (maybe it never existed and I imagined it), but it is a screen magnifier that only magnifies a small circle around your fingertip, like the equivalent of a 5 letter word, ideal for magnifying specific words or areas of your screen, I think I saw it once (on iphone maybe?), you just need to keep your fingertip on screen for about 2 seconds then a small circle appears above your fingertip magnifying anything under it, and you can move it all around your screen, and disappears when you lift your finger, is there such thing? There is the triple TAP but it zooms the whole screen and I do not want that.

I searched desperately for a way to do that but in vain. so far it looks like the only way for zooming using mouse in android is clicking twice the left button and dragging up or down, which is very awkward and frustrating and out of common sense. I tried to find a key mapper on Googleplay but I found nothing which handles mouse buttons. I also looked for an image viewer with any options for mouse input, and nothing I found.

I have some Android TV "sticks", such as the RK3188, which is basically a tablet minus the screen. You control them using keyboard and a mouse. The problem is, I have no way to zoom in or out in the browser. There's no way for me to do a "pinch" gesture, and Ctrl +/- etc. don't seem to work in any browser, like Chrome, FireFox, and Dolphin. I'm using the box as a display screen in a public area and not being able to scale the content to fit the whole TV is a serious limitation. EDIT: Double tap only offers 2 zoom levels "close" and "far".

We zoom in and out using two fingers in an android app such as PDF viewer or map. If I use a bluetooth mouse, how can I do this? The wheel does not seem to work for this purpose.

In some camera apps (native camera app in 2.2, Camera 360), "zoom" zooms in on the image -- filling the entire screen with a closer-in view of what you're shooting. In at least one app (Vignette [see below]) "zoom" shrinks the picture down. The latter behavior -- along with surely-lacking mechanical lens focus mechanism -- suggests that all of these zooms are purely digital, and not optical. See Also: Can a Dream's camera really zoom from the camera app? [device-specific question]

In almost all Android devices, zoom is digital -- there just isn't a mechanism for changing the length of the barrel and gathering more info. So how is **focus** achieved? If you're not physically changing the lens properties, or extending the barrel length, you've only got dilation of the aperture as the last focus method. Which is mechanical. Unless you've got a fixed focus system -- which most android phones do not seem to have. The android-spec for the autoFocus() method isn't much help - although it says it must be supported by the hardware, although most phones seem to have it. So if it is hardware -- how? I'm not hearing any little motors whirring around in there.... And is there really even any room for a mechanism in these things?

I'd like to edit an image to add a "magnifying glass" ring with a magnified region inside, like in the screenshot below. The standard Gallery editing tools can't do that, and I've tried a few other apps with the same result. Is there any way to add this effect (zoom certain part of image) using any kind of Android app?
