touch screen : I'd like  to remove this.  Kindly provide step by step instruction

I have a Samsung SmartPhone with numerous photos and a few videos. I need to get them on to my PC (Windows).I hooked it up to a USB port on my computer. I see a bunch of folders, including PHOTOS. However, this folder seems not to have my videos. (On the phone, they seem to be in same folder.)

Here's a list of folders. Where would the videos be?

Where is video folder?

I set out trying to find an android app that would allow me to add a previously called number to sales prospects from my phone easily. I downloaded the Base app here but it doesn't seem to do this.

I know Base has a large following and I think it has free features. Do I need a different product or can Base do this?

Assistance is greatly appreciated.
I used "Custom Notifications" on my Galaxy Note 2 previously for some critical Whatsapp group
(which I need to respond urgently) by making new messages to pop up with a custom sound.

After migrating to Note4 (Note2's screen broke), I set the same custom notifications but only
the "popup" for new messages surface but no sound.  Is there a setting somewhere that I

I have a Samsung Galaxy S7 and I use Android Auto to connect to my car.  I recently lost the ability to use the voice command "Ok Google". I can still prompt it if I touch the mic on my car dashboard and then voice command whatever I want it to do..

Note: That this has worked before with my current set up. It may of stopped working after a recent phone update, but I can't be sure.

My settings in Android Auto are on to allow voice command. Are there any other settings that might be causing this?

What's the best way to troubleshoot?

I would like to monitor ingress and egress to my home and yard.

I need it to be able to notify me every time it recognizes someone that shouldn't be there.

The most important location to monitor is when people come up to the front door from the street which is about 50 ft away.  I would like the smartphone camera there to be good enough to see activity actually at the street level.

I am really looking for best in class here within reason cost-wise, and suggestions are greatly appreciated.
We plan to begin coding (Delphi 10.x) application for smartphone, in a first stage, accessing the customer database, the smartphone being connected to the customer local network.
It seems I have two alternatives : Direct access or REST/HTTPS layer.
Is there some documentation explaining advantages and disavantages of both methods ?
one of our corporate applications have recently issued a windows/android app for smartphones, to give the users an alternative to using their web app. the suppliers are a relatively small company. Some of the end user smartphone devices are currently not encrypted, but the suppliers say this is not a show stopper as security is 'contained' within the app itself. The login to the app is single factor authentication, username/password. how practical is it that security for an app would be 'contained' within itself, so if someone lost the smartphone with the app itself there would be no data specific to the app accessible on the devices storage. And perhaps more relevant what type of testing would you suggest to see what data specific to the app is stored and retrievable on the phone itself? or what types of security sensitive data do/could apps leave on the phones themselves and what could be retrieved if the device was lost/stolen?

Is there any good examples to explain how should we build the data pulling section in mobile app development? I heard about the word asynchronous often but what is it actually?

I need something that explain the concept rather than pure programming examples (but good to know if it's also provided)

Any clues?

Thank you.
I'm in the process of listening to a book that has each chapter saved as an .MP3 file.

This book is contained within a folder within my Spring PCS Android Samsung Galaxy S8 cell phone.

Currently only one chapter plays at a time and then I have to find the next chapter's MP3 file on the phone and play it next. I need the book to play non stop.

How can I set this book to play one chapter's MP3 file one after another using the MP3 Player app which I installed from the URL link below?
How can I determine which apps installed my Android Samsung Galaxy S8 phone are demo & can be purchased?

How can this be done?

I know someone who publishes an iPhone app which currently has an input field for the credit card number. But, this means the user must type it in, which is error prone and slow. So, I hope to reconfigure without even any coding changes to the app.

This is the kind of device I need to use...

My question is...

Can one of these be used along with the app, on an iPhone, to get that credit card number into that field, but do so without  requiring any modifications to the app?

I see that some require a merchant account, and those will not work. The app I am describing must run and communicate with the server. It can not use an existing app to transmit the information.

All I need is a way to automate the manual key entry of the credit card #. So, can any of these readers be configured to insert the credit card # into that field?

I suppose, worst case, if the card reader inserted the CC# into a note, so it could be copied and pasted, that might be better.
