Applications – What is Market on an Android Device?

When looking for a problem, I came across 2 questions and the related answers that related to "Market" (for example, "Application Always Downloading").

I have never heard of this app and could not find anything on my phone that looked like it at all. I also could not find it in Google Play or the Google search engine and could not find anything about it.

Which metric does Spotify use to decide if a device is a phone or a tablet?

Granted, the border between "tablets" and "cell phones" has been blurry for years, and there is no universally accepted distinction.

But I'm curious to see which metric Spotify uses to decide if a device is calling a phone or a tablet.

Most people would call my OnePlus 7 Pro a "phone," but Spotify identifies it as a tablet:

Which metric is used here? And why?

Could not start django – gunicorn.service: Device is not loaded properly: Invalid message

I'm having trouble configuring Gunicorn. So far, I have pulled my Django code onto the server, created a Virtualenv for Python 3.6, installed Django Gunicorn Psycop2 with Pip3 and that's all right.

I can run the Django development server and see my undesigned site and have successfully posted to the database through the admin site for it to work. I then started it directly with:

gunicorn django_version.wsgi:application --bind 10.88.58.95:80

and again I could see my non-styled page. I also tried:

/srv/pcc_django/django_env/bin/gunicorn --workers 3 --bind unix:/srv/pcc_django/django_version/django_version.sock django_version.wsgi:application

and that started without mistakes. So my next step was to write a .service file:

(Unit)
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

(Service)
User=user
Group=nginx
WorkingDirectory=/srv/pcc_django
ExecStart=/srv/pcc_django/django_env/bin/gunicorn --workers 3 --bind unix:/srv/pcc_django/django_version/django_version.sock django_version.wsgi:application

(Install)
WantedBy=multi-user.target

and try:

systemctl start gunicorn.service

I get the above error message and it reads:

systemctl status gunicorn.service

and it gives the following message:

‚óŹ gunicorn.service - gunicorn daemon

but there is something strange going on, because when I do it:

date +%H:%M:%S.%N

I get the following timestamp:

11.57.13.124995238

So I am not sure if this message refers to an incorrectly starting Gunicorn service. What did I miss that prevents Gunicorn from being started as a service?

Device recommendation – Decision between Canon SL3 and T7i

The Canon SL3 was released this year and has some improvements over the T7i, but also some setbacks.

The biggest differences I've seen are the image processor, battery life, and autofocus. The SL3 has a newer DIGIC 8 image processor compared to a DIGIC 7 on the T7i. The battery life of the SL3 is superior to that of the T7i, 1070 shots versus 600 shots (under the same conditions). There is a catch though. The T7i has 45 autofocus crosspoints, while the SL3 has only 9 regular autofocus crosspoints (one cross point). Although the SL3 has a dual-pixel autofocus, this only works in live view.

This will be my first camera. I would like to be able to photograph everything from portraits to running children (hence my concern for autofocus) and now and then sport. Live View may be a great way to start taking photos, but I feel like I'll probably use the viewfinder later to disable dual-pixel autofocus.

I do not mind the small difference in the frame rate, 5 for the SL3 and 6 for the T7i. I will also mainly shoot, but if I record a video, it will only be in 1080p because of the cropping factor and the lack of dual-pixel autofocus in 4K.

Two specific things I would like to know:

  • How does the autofocus of the SL3 relate to the autofocus of the T7i (for photos, with and without live image and video)?
  • What difference does the newer image processor (in low light conditions)?

How do these two cameras compare? Is there a difference in the overall picture quality? Are there any other differences I missed? Which would be the right choice for me?

To edit:
I will shoot in RAW.

google pixel – "Your device is 10 days old" … unexpected notification, is it malware?

I have an unlocked Pixel 1 (bought directly from Google in 2016). I have never installed anything from an untrusted source.

I just unlocked my phone and got a pop-up similar to the Notification / Amber Alert message with the message "Your device is 10 days outdated," prompting me to update by clicking a button (with the warning that the download was performed) 948 mb and mobile charges may apply). There was a link "Further Information" that did not work. The popup also had a "remember me later" button that I accidentally clicked when I tried to take a screenshot.

I know Pixel 1 has a very bad (zero-day) vulnerability, which leads me to believe that this may be legitimate, as it fits into the timeframe for publishing the update. I have not installed Android 10 yet, but this is a normal notification that hangs around in my notifications.

Is this a legitimate push notification for Pixel 1's zero-day vulnerability coming in through non-standard channels? Or is it malware? How can I confirm one way or the other?

  • This is the only popup I have had so far. I turned my phone on and off all day and it only appeared once.
  • I have not installed new software for weeks (and only from the App Store)
  • Operating system updates come as push notifications from Google and are standard Android and definitely not available as a bizarre popup.

Privacy – How to check if the device is doing exactly what it should do?

I am very sorry for the misleading and confusing title as this was the best thing I could think of.

What I wanted to ask is, how do we know that a device does what it should do? For example, Android is an open source operating system (ignore Google libraries at the moment) and they claim that all passwords are only stored on the device, but what if they store it on their servers and that code is not there The open source version is only available in precompiled libraries. How can we verify that the same code exists in the actual phone and open source version? The same applies to other devices such as iPhone, routers, desktops, etc.

In addition, most manufacturers today have enabled encryption that makes it impossible to monitor the actual contents of the TCP / IP packet.

We can always remove existing operating systems and install the open source version, but this is not possible in all cases, as in some cases, it could be really confusing and even require many extra things that people do not normally have.

So my general question is how to check if the same code exists in the open source version and in precompiled binaries. I can think of reverse engineering, but that would require a lot of knowledge and skills that most people do not have.

Unbricking – Unbrick pixel device

I accidentally flashed Qualcomm ROM in a Pixel device.
After that the device will not boot anymore. Not even the power switch works. Most likely hard brick. Running lsusb shows

"Qualcomm, Inc. Gobi Wireless Modem (QDL Mode)"

Is there a solution to this problem?
Please help me out somebody. Attached screenshot.

I had a script for flashing Rome. Content of the script can be found here.
The issue printed during the flash can be found here.

rom flashing – Is it possible to repair a tough device?

I work as a technician in an electrical repair shop and I started 4-5 years ago, but something really bothers me.

Why can not we repair hard-walled equipment? Like device hardware perfectly fine. Is there a device for this problem?

I have 5-10 gadgets lying dead just because of the hard brick because some amateur was trying to flash a ROM without any experience

I also do not know if this is the right place to ask this question. I'm basically trying to flash an Android ROM, but if it's not the place to do it, I can delete my question and please, if you're not% 100, do not write "You can not fix hard-walled equipment," I have heard and said that for a long time
