Inability to print through Default print service

Bob Hawkins
I purchased a Samsung Galaxy Tab A 10.5" running Oreo 8.1 recently. I understand "Default print service" was introduced in this version, which is present in Settings>Connections>More connection settings>Printing/PRINT SERVICES. It is switched on and finds my HP Envy 5640 series [144552] printer. Opening, as an example, BBC Food and a recipe, tapping "Print recipe" has no effect, nor does "Print..." appear in the drop down menu.
My mobile 'phone is a first generation Motorola running Lollipop version 5.1. It has HP Print Service Plugin installed by default. Opening the same BBC Food web page, the drop down menu displays "Print...". Tapping that or "Print recipe" opens a new page that is the HP Print Service Plugin, which allows me to alter elements and print successfully.
I know little about printing wirelessly but both HP e-Print and Wi-Fi Direct are on and the printer has no issues, so far as I am aware - I print wirelessly from my Windows PC. I have printed an Inbox email from this tablet successfully, also.
I do not wish to have to download another app such as HP or Samsung Print Service Plugin or Google Cloud Print, when it seems Default print service is present precisely to avoid such a process. I am at a loss, however, to know what next to do.

Internal memory full!??

S
My device keeps telling me that the internal storage is almost full (15.5 of 16gb used), but I have no idea how it's full.
I have uploaded a screenshot of all the folders in my internal memory, which only adds up to 6.63 gb.

Any ideas where else I should be looking??

I have deleted heaps of photos and videos etc. but the space just keeps disappearing.

Recommended charging cable?

ROBOCRIPPLE
My last daily driver was a OnePlus 3. I've had this phone for about 3 years, since it first released. It served me well until the summer of last year, when the front panel started coming off. I went into a phone repair shop, only for them to tell me that "OnePlus phones are not repairable" and that the problem was with the battery being inflated. I was pretty disappointed.

I used a third-party charger most of the time, and overnight. I have that charger placed in the base of a multi-device stand, where I store my devices. I also used a cheap Chinese 1ft USB-A to -C cable to charge my OnePlus 3. I learned that you're supposed to only use the cable and charger that came with your device to increase its longevity. I made the mistake of using them only on the go, in my travel pack. (I'm pretty lazy) Now I'm suspecting that the cheap Chinese cable that I used contributed to the battery's inflation and degraded life.

I had a Samsung Galaxy S3 before the OnePlus 3 and its stock battery degraded and inflated by 3 years, but I was able to swap the battery out for another, larger one. IIRC, I didn't use the charger and cable that came with it all the time, either.

I have a Samsung Galaxy S10, now, and I want to use it for 4-5 years. I hear it's compatible with Qualcomm Quick Charge 2.0. (kinda wish it supported 3.0, instead) The charger in my phone/tablet stand does have a Quick Charge 2.0 port (I've had it for about 3 years, now), so I can still use it with my Galaxy S10. But I also want a cable that is about 1 ft long and works well with the S10 line. I'm looking on Amazon; they do have cables advertised to work with the S10 line, but I'm not too sure...

If the problem was not (entirely) the cable that I used, should I change my charging habits?

Rant: I kinda miss the old days, when cellphones would last more than a day on a single charge. Partly (or mostly) due to the fact that most people only used them for calls and texts. Since the original iPhone came out, people have been using smartphones for much more, especially social media, and so they don't last very long, anymore depending on usage. I couldn't really accept that fact since I had my PSP. The reason I recharge my phone/handheld overnight is because of its semi-decent battery life, and I don't want to budget/limit my usage of it. That's probably why people buy portable power banks, as well. I'm hoping that in the future, we have a new rechargeable battery technology that is more compact than lithium-ion and lithium-polymer, doesn't degrade or inflate over time or usage, and lasts more than a day, so that we can go back to using our phones and handheld gaming devices kinda like the old days.

Note 8 doing some things twice after Pie update

sachertorte
I got updated to Pie a couple or few weeks ago, and just ten minutes ago got another update. Pie is working fine when started, but there is an issue present on startup that did not exist before the upgrade. When starting up, my phone now does some things twice. I get the keyboard flashing on, then off, then on, and it stays on till I input my password. I also get my notifications flashing on, then off, then on, to stay on. These are the ones that show up in the swipe down menu. I am on AT&T. Has anyone else had this?

Thanks,

Danny

Pre rooting questions.

Mplsyrp
A back up seems like a great idea, while I understand that it is ultimately up to me, and that ratings do mean something regarding the quality of a app.
Sometimes the masses do not always recognize quality.

Phone--- Pixel
hardware-- PVT
PRL version-- 55071
ANDROID
v-- 9
Security path level-- 05 April 2019
Base Band-- 8996-130181-1811270246
Kernel version 3.18.122-g665c9a1
#1 Fri 11 January 21:46:31 UTC 2019

My PC runs Ubuntu 16.04.0

I would appreciate a couple of quality options for a back up, and which app to actually root with.

Thanking you in advance

I do not know about anyone else, but I try not to rush, when it seems important.

Why Image is becoming blur when i try to display in image view

N
Hi can anyone please clear my doubt. am trying to display an image which is captured from camera in imageview which is in 2nd activity. but image quality is becoming very poor. an anyone tell me why is that and how to resolve it. This is my code please see

Activity 1 (MainActivity)
Code: 
if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK  )
{
    Bundle extras = data.getExtras();
    Bitmap imageBitmap = (Bitmap) extras.get( "data" );
    long height = imageBitmap.getHeight();              // the height is 204
    long width = imageBitmap.getWidth();                //the width is 153
    long filesizeinBytes1 = imageBitmap.getByteCount();
    long fileSizeInKB1 = filesizeinBytes1 / 1024;      // 60KB
    Log.d( TAG, "Textview message :" + height + " , " + width + " , " + fileSizeInKB1 );
    System.out.print( fileSizeInKB1 );

    File destination = new File( Environment.getExternalStorageDirectory(), "temp.jpg" );
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    imageBitmap.compress( Bitmap.CompressFormat.JPEG,100,bytes );
    FileOutputStream fo;
    try {
        fo = new FileOutputStream( destination );
        fo.write( bytes.toByteArray());
        fo.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    Intent intent = new Intent( this, Main2Activity.class );
    startActivity( intent );

And now am retriving image from sd card to imageview .

Activity 2(Main2Activity)
Code: 
File destination = new File( Environment.getExternalStorageDirectory(), "temp.jpg" );
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
Bitmap bmp= BitmapFactory.decodeFile( destination.getAbsolutePath() );
bmp.compress( Bitmap.CompressFormat.JPEG,50,bytes );
image.setImageBitmap( bmp);

long height = bmp.getHeight();                                  // the height is 204
long width = bmp.getWidth();                                    // the width is 153
long filesizeinBytes1 = bmp.getByteCount();
long fileSizeInKB1 = filesizeinBytes1 / 1024;            // 121KB
textview1.setText( " Height:" + height + "Width" + width + "size in KB:  " + fileSizeInKB1 );
Log.d( TAG, "Textview message :" + height + " , " + width + " , " + fileSizeInKB1 );
System.out.print( fileSizeInKB1 );

Am compressing the image but the image is becoming from 60KB to 121 KB and when i check in sd card it is 22.4 KB Why is that please explain.And even if it is becoming from 60KB to 121KB it is blurry in imageview Why is that ?

Pixel turns off without warning

J
For the last few months my Pixel (gen 1) has started arbitrarily turning off anytime the power level gets about 50% or less. It doesn't to the "powering off" like when you choose to turn it off. It just turns off. You have to plug it in before it will turn back on. Needless to say this is very aggravating.

Sometimes it goes all the way down to 0% before turning off. I have tried to let it go to 0% to see if that would reset the battery level but it hasn't helped.

Also, besides just turning off, the warning about battery running low also pops up at any time. It only used to do that when it hit 15% and power saving mode kicked in. Now it does it at the same level as when it turns off unexpectedly, anywhere below roughly 50%.

Is this just a problem with the gen 1 Pixel? Can nothing be done to fix it? It works great otherwise with no other problem.

Offline Storage

C
Hello Everyone!

I'm building an app that needs to work offline, and when internet is available it should push some records to a server and update other records.
During my research, I found out about Android Sync Adapter and begin to implement it.

However, now I'm stuck on how can I consume the data from some endpoints to keep the data up to date?
Or is it not possible?

Regards!

Help Qi Charging Feature Detection on Nexus 7

J
I recently purchased at Nexus 7 (2013) expecting Qi charging capability. However, not only does it not charge when carefully placed on a Qi charger, every app purporting to detect whether Qi charging is available on the device reports Qi charging is not available on the device. Are these apps reliable?

Before sending it back, I'm tempted to open up the case to see if the Qi coil is in the device, but am rather confused by this situation, particularly given the persnickety nature of Nexus 7 Qi charging.

I'm even wondering whether I've been a victim of false advertising -- that it is a 2012 rather than 2013 model, however when I check system information with various apps it shows RAM is 1.77GB.

How to view SD card files from Moto X Pure?

L
recently just picked up me and my wife S10+s. After having the pure for about i year i figured id try iphone a try since i was always primarily an adroid user. Well after enough of hearing about how my wife hated her iphone i switched back. i have an SD card that was used in my X Pure that has some nice photos and memories from before i enlisted on it and id like to be able to recover them. i stored the SD card in a holder for some time and now that i finally have another android i tried loading it up on the phone and it shows a couple folders where i know there would be some data but there is none. To the best of my knowledge i did not encrypt the sd card. but iirc it was switched to be part of internal memory. i remember vaguely me not being able to access the files even with the Pure connect on my laptop back then aswell. Its 16gb and only gets recognized as having 55mb. do you guys got any tips at all for me to be able to view the files on my galaxy? or recover them someway on my laptop?

(also) the way they enabled to transfer files and videos from iphone to android with the connector provided honestly was the coolest thing ever haha

Unique help/requirements needed to video call

upnorthisbest
Hi. My mom is a senior with very poor dexterity and motor controls (hands). I'm awaiting a sim card to reactivate her phone, and am stuck to just wifi in the meantime. When the phone works, I have large 2x2 direct dial widgets setup and the LG phone defaults to speaker. This allows the phone to remain stuck to a bed side table via velcro. She double taps the screen to turn it on, swipes to unlock, then single taps the large widget to call.
However, I won't have the sim for a few more days. In the meantime, I am trying to find a video chat app that can offer similar functionality. It could also be completed with a short cut app. Be creative! I've been searching quite a bit and have not found a great solution.

Must have:
- One touch video chat start from home screen.
- App must not require a phone number, email only

Very nice to have:
- large 2x2 or larger widget to initiate the video chat from home screen.

Many thanks if you can help. This has been far more complicated to accomplish than I thought it would.

Help Rear Camera Issue and Android Pie Update`

O
Hello:
This is a two part question so please bare with me.

1st) My rear facing camera has gotten blurry since my glass cover broke last year. I have since replace the glass but the camera is still blurry. I have tried a few tricks I read on the net like tapping the camera or updating the software or trying to use a third party software but none seem to work. So my only recourse, outside of getting a new phone which I do not have the money for, is to replace the camera. I have tried to find the right one but I am having trouble in that. I have a T-Mobile Samsung Galaxy J7 Prime (SM-J727T1) with the latest Android it supports (8.1). The camera is an 8mp device but all I can find are 13mp. I have been told by one person that my phone will not support a 13mp camera due to the OS but I do not understand why. So if some one can help me find the right one or show me a way to make the 13mp one work. Thanks!

2nd) Now that Android 9 is out can I update my phone to Pie and if so, Can you tell me very specific steps in order to do this. Thanks to all who help out in anyway.
