help drive stopped samsung tab e

Hi, you stated your cellular service is Oi in your profile page, which after looking it up online shows it to be a service based in Brazil. Yes?
https://en.wikipedia.org/wiki/Oi_(telecommunications)
Anyway, your question is a little hard to figure out. I'm guessing it's just a language and phrasing issue so could you ask your question again with a more details please?

When and how will communication technology stop?

Trom
Hadron said:
Yes, it's possible to flip the spin of a particle. But you can't determine the result of the initial observation - it will be up or down with whatever probability the initial state would give - and once you have made that initial measurement the entanglement is broken, so anything you do to the spin afterwards will have no effect on the distant particle.

That's the problem: the distant observer cannot even know whether you have made a measurement of your particle, nor what direction you measured in. You could agree in advance when you would do this and what axis you would use, but that would only allow you to infer what the other person had seen (if you use the same axis, not even that if not). As far as communication goes that's like trying to send a message by flipping a coin and telling the other person which way it lands: since you can't control it it can't encode a message.

Stuff like this is what annoys me about layperson books, they need to tell the whole story, rather than assume I'm we Todd Ed and can't wrap my head around reality. Perfect example, guy at work tells me some group at Harvard slowed the speed of light down to 38 mph, which is just dumb. But duck+ that, and you'll find story after story about that group slowing down the speed of light to 38 mph.

camera focus is jumping

D
Hi, I'm trying to film a simple video on phone. You can see in this test video, around 9 seconds in, the video jumps in and out briefly:


It's a slight jump in that video, but I have other videos where this issue is much worse. Seems to be related to auto-focus.

I've tried to record on standard android camera app, and on Open Camera app, but I get jumping no matter what. Also, this happens in low and highly lighted environments.

Even though it's a Samsung, I know phone is lower end. But cheap camcorders 15 years recorded better than this.

Any suggestions on how to prevent this jumping from happening?

Thanks for any help.

System Update 13

I'm not 100% sure, but there should be an option called "Accent color" under Display settings. Maybe try searching for it in the settings. Some people say they don't have that option though, so not sure if you'll have it.

I haven't received the android 10 update yet, so I'm just going by what I've read online.

Thanks, I did find that setting. However, it only changes the color of the buttons and sliders. Still very useful, just different. So thanks for the information.:thumbsupdroid:

Do Front Cameras Reduce Notification Icon Space?

C
I would think it's negligible on the phones with only one front camera. On phones with two like the S10 5G (think the plus also) it's a significant drop in status notification space in my opinion. I found an article to confirm it and there's a setting to let you turn on a virtual top bezel. Considering these phones are 19:9 aspect ratio and a standard HD video is 16:9 in my opinion turning the virtual bezel on, on the S10+ and S10 5G seems like a no-brainer if you typically have a lot of notification icons. There very small amount of screen space you lose wouldn't really have any functional impact. I think the only downside is some people may prefer to have a display covering the entire screen at the expense of status notification space. Guess I will experiment between the two and see what I end up liking best.

https://gadgetguideonline.com/s10/how-to-use-galaxy-s10-virtual-bezel-to-hide-the-front-camera-cutout-without-using-any-apps

"The hole must keep a certain distance from the curved part. This results in a significantly-reduced area for the status bar. So, Galaxy S10 has to offer the option for you to reduce the number of notification icons on the status bar or even hide/disable the notification icons on the status bar entirely...
If you want to hide the front cutout on Galaxy S10, you can use Galaxy S10 virtual bezel to achieve it at the cost of reduced screen size."

Is there any way to put a ViewPager2 inside an AlertDialog?

Dnlaua
I'm losing my mind. Spent over 5 hours rearranging code thinking I was one step away from fixing the issue due to being able to have half the functionality with one parameter change, and the other half of the functionality with a different parameter. I WAS WRONG. NOT CLOSE. I'm hoping you guys can help me.

I'm trying to put a ViewPager2 inside of an AlertDialog that's inside of a RecyclerView. I was going back and forth between having the AlertDialog have the .xml with the ViewPager2 scrolling functionality with the save button not working to dismiss dialog, to having the .xml load, save button work, but no ViewPager2 scrolling. Here's my code for the latter:

editItem()
Code: 
{
final AlertDialog.Builder alertDialogBuilder;

inflater = LayoutInflater.from(context);

final View contentEspressoList = inflater.inflate(R.layout.content_espresso_list, null);
//final View view = inflater.inflate(R.layout.activity_espresso_list, null);
final View editItemPageView = inflater.inflate(R.layout.edit_item_page, null);

viewPager2 = (ViewPager2) contentEspressoList.findViewById(R.id.editPager);

alertDialogBuilder = new AlertDialog.Builder(context);

//viewPager2.removeView(viewPager2.getRootView());

alertDialogBuilder.setView(editItemPageView);

final AlertDialog dialog = alertDialogBuilder.create();

viewPager2.setAdapter(new EditViewPagerAdapter(dialog.getContext()));

dialog.show();

saveButton.setOnClickListener(new View.OnClickListener()
{
    [USER=1021285]@override[/USER]
    public void onClick(View v)
    {
        dialog.dismiss();
    }
});
}

EditViewPagerAdapter.java
Code: 
public class EditViewPagerAdapter extends RecyclerView.Adapter<EditViewPagerAdapter.ViewHolder>
{
    private String mName;
    private LayoutInflater mInflater;
    private Context ctx;

    public EditViewPagerAdapter(Context context)
    {
        this.ctx = context;
        this.mInflater = LayoutInflater.from(context);
    }

    [USER=1021285]@override[/USER]
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
        View view = mInflater.inflate(R.layout.edit_item_page, parent, false);

        return new ViewHolder(view);
    }

Reviews Does S20 really contain 64 MP?

Eric Parlatore
Hadron said:
Well your main question was whether there was a 64MP sensor there
wink.png
.

You'd have to ask Samsung why they made certain decisions, but the first thing to remember is that this isn't a 64MP telephoto camera: it's a 64MP wide-angle camera (almost as wide as the primary) and that the zoom comes from cropping and software interpolation (i.e. digital zooming). The difference is that the 64MP gives you a bit more scope for cropping before you start to rely heavily on software for the zoom (there is no real optical zoom on the S20(+), only on the Ultra).

So as for what's happening, I don't have one of these cameras so am just working from what I can read plus a bit of educated guesswork. But here goes:

The first thing to note is that you won't get 2MP from a 6x crop of as 12MP image, nor will you get 10MP from a 6x crop of a 64MP image. When people talk about zoom ratios they refer to the angle of view, i.e. the linear magnification, while 12/64MP refers to the area. So a 6x zoom by cropping a 12MP image would give you a 0.3 MP image (VGA resolution). So digital zoom isn't simply cropping: they crop and then they do a software interpolation to scale that back up to a higher resolution. Try taking a picture, zooming by a factor of 2 then taking another, then look at the properties of the images: you'll find that they both say they have the same number of pixels - that's using software to 'scale up' the resolution back to what you set it to. Of course you don't get extra information this way, so the real image quality is always inferior with digital zoom compared to a true optical zoom.

So my guess is that if you select '12 MP 6x zoom' it will produce a 12MP image using software zooming (about 4000x3000 pixels). Now set it to 64MP and tell it to take a 6x zoom image: what resolution does it say the image has? Does it give you a 64MP zoomed image, a 12MP one, or something inbetween (for small zoom factors)? My guess is that it will rescale to 64MP, to be consistent with what the setting said (you asked for 64MP so the camera gives you it), but I'd be curious to know whether I'm right. If it does something different then it changes what I speculate below.

Then it gets more speculative: you say that you get 30x zoom in the 12 MP setting. What resolution are the 30x zoomed images? My guess is 12MP. Now an actual 30x digital zoom would be utterly worthless: a 30x linear crop contains 1/900 of the original pixels, so scaling that up to the original resolution is going to look like crap. So my theory is that the '30x zoom 12MP' is actually using the 64MP sensor, just rescaling back to 12MP rather than to 64MP (it will still look like crap, but not as bad as doing it with the 12MP sensor would).

As I say, I don't have one of these phones to test, so I may be wrong. But my guess is that it will do something like this:

* When you select 12MP or 64MP you are not so much choosing which sensor you use but what resolution the image is.

* If you set 12MP mode and start zooming, at some point it will switch from using the 12MP sensor to using the 64MP sensor, but it will always rescale the zoomed image to 12MP. At what point it will switch I don't know (6x would be an obvious guess, given where the 64MP mode ends, but it might happen earlier - it might even happen the moment you start to zoom).

* If you set 64MP mode it will use a digital zoom up to 6x, rescaling the image to 64MP. Above that it will stop because the image quality loss is too large for it to be worth rescaling up to 64MP, and so if you want a &gt; 6x zoom you have to choose lower resolution (i.e. 12MP, even if that actually uses the 64MP sensor for part of the range).

But as I say, that's only a guess. It could even be that they just use digital zoom on the 12MP sensor all the way to 30x and the purpose of the 64MP sensor is to give higher quality zoom images, and they cut that at 6x because anything more than that is losing too much quality. But given how outlandish a 30x digital zoom is my guess is that they actually use the 64MP sensor for that then rescale to a lower resolution - at least if you asked me to implement a 30x zoom with that hardware, that is the way I'd do it.
