Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).

What happened when I tried to make my phone, a Samsung Galaxy S8, stop dropping all WiFi signals was a saga I won't repeat here, but what you might want to know is how it started and how I got it working again.

Android Email Apps
In my humble opinion (IMHO), TouchDown from Symantec is the best in class for this type of application, but Symantec has end-of-lifed it and although one can keep using it, it will no longer be supported or upgraded. Time to look for alternatives to getting Exchange email on your Android phone.

Ransomware, the malware that locks down its victim’s files until they pay up, has always been a frustrating issue to deal with. However, a recent mobile ransomware will make the issue a little more personal… by sharing the victim’s mobile browsing history.

Modern OS from Windows 7 onwards will disable disk cache and you will not have performance gain on using a RAMDisk.

Besides, the wearing from disk read and write will not have a significant impact to your SSD.

https://www.howtogeek.com/256859/dont-waste-time-optimizing-your-ssd-windows-knows-what-its-doing/

I have changed the HDD to SSD for a number of desktop PC for more than 18 months and they are still running to top speed like Day 1.

Before I changed to SSD, I did use RAMDisk to make Windows 7 ran faster by moving all cached and temporary files to the RAMDisk and my experience shows that the article in the link above is correct.

Besides, unless you are staying with 32 bit MS Windows, you will not have spare RAM for RAMDisk and it is better to let the OS to handle memory management.

I found that on my Windows 10 64 bit machine with a 256gb boot SSD (1tb data drive HDD 7200rpm), RAMDisk made a huge difference.  I found the same on my brand new laptop (Lenovo Yoga) with SSD.  I even bought the software.

Does your company store data on premises, off site, in the cloud, or a combination of these? If you answered “yes”, you need a data backup recovery plan that fits each and every platform. Watch now as as Percona teaches us how to build agile data backup recovery plan.

There is a lot to be said for protecting yourself and your accounts with 2 factor authentication. I found to my own chagrin, that there is a big downside as well.

Ultra-power saving mode is developed by SAMSUNG and SAMSUNG do not expect that you will prefer to use Google Now Launcher instead of TouchWiz launcher.

I have tried to use Google Now Launcher but its support on Chinese is poor and I dropped it.

The only problem of Ultra-power saving mode is that it will disable all sync for email accounts after you exit Ultra-power saving mode and you need to manually re-able the sync of all email accounts,

Jackie,

I don't use the built in email reader and did not have that problem with email.  I use touchdown from Symantec for my exchange/work email and inbox from google for my gmail email.  Both of these apps seem to work fine after coming back from UPS.

Hmmm... I have Marshmallow on my S5 and the Now launcher isn't standard (which I take to mean is included by default).
Here's what my home screen looks like.

By the way, you should try to embed the comparison shot in the article, as the title totally obscures it when viewed on handheld devices. (Going to check it on my laptop, next.)

I appreciate the effort that goes into making an article, especially in English when that is not your first language.

I don't think that "there are billions of billions users using android OS worldwide" (bold added by me for emphasis).
There aren't that many people in the world.  :)
The last statement I saw (claiming it came from a Google head) said that there are now one billion Android users.
