Which processor in my unit? - (Who does not want to bother to put the official site.. Web-release: For all processors . What is Web-releases )

Try usingDroid Hardware Info. The Droid Hardware Info to see the architecture(Hardware Tab - System) ,
orAIDA64AIDA64 to see architecture(CPU tab \ CP) Is it possible to put the application on arm64 arm device? And the application arm on arm64? As x86 and x86_64?

64-bit operating systems are backward compatible with 32-bit applications, but not vice versa, so you can safely put a 32-bit application on both 32-bit and 64-bit operating systems, but not vice versa.

32-bit application on 64-bit operating system may not be as optimized, so if a 64-bit device you install the 64-bit application, as soon as it appears, if it exists, of course. Many developers simply do not bother to release a 64-bit application.
So:

• arm to arm the device:OK;
  
• arm64 to arm the device:not;
  
• arm on arm64 device:OK;
  
• arm64 on arm64 device:Ok

It is the same for both x86 and x86_64.
Thank,iMiKED. for the materials.

About a billion people around the world today rely on WhatsApp to stay in touch with their friends and family.
It is for these reasons that we are pleased to announce that WhatsApp will no longer charge the monthly fee. For several years, many people paid a subscription fee after the first year of using WhatsApp. With the development of the company, we realized that this approach was not proven as effective. Many Whatsapp users have no debit or credit card, so they were concerned that they could lose touch with their friends and close after the first year of use. Thus, over the next few weeks, we delete a subscription from various versions of our application. Whatsapp will no longer charge the fee for their services.a source

When you get to the screen "waiting for incoming sms", turn off the air mode.

• What to do in case of loss of the smartphone? Since WhatsApp does not check which SIM card is installed in a smartphone after activation, even if your device is inserted another SIM card, the messages sent to you in WhatsApp will still come to the device until you activate whatsapp on that Number on another device.

According to the developers at the end of August 2012, they have corrected the situation and since then messages are sent in encrypted form. But at the same time, the encryption method is not advertised, and I did not stumble upon any independent research and confirmatory experiments in this field, unfortunately. Therefore, how well everything is encrypted there remains a secret under seven seals.

• Is it possible to simultaneously connect with two devices by one account? Not. It is possible to install and register the same number in programs on multiple devices and exit from them sequentially (i.e., at each time the Internet is included only on one of these devices). However, as soon as the Internet appears simultaneously on several, and, accordingly, the WhatsApp server recognizes the multi-login attempt, on the device that will try to connect the second, say "You have already logged in a system from another device with the same number. It is necessary to pass the reload ", and will not allow the program to re-confirm the number.
  
• Can I exit the program? When I'm online and when not? WhatsApp automatically starts when the smartphone is loaded and automatically connects to the servers as soon as it detects the available Internet connection (both WiFi and 3G / GPRS). The messages sent "to offline" will come as soon as the recipient on the smartphone will appear an Internet connection. You can exit the program only using the standard Android application management menu (Main screen - Settings - Application Management - Working Applications - WhatsApp - Stop).

[*]Can I install the program on the tablet, and without a SIM card? If you have Android 4.0.3 +, you can first try in the forehead: Download APK from the cap and try to install. There is another way to install on a tablet without the need for root-rights without a SIM card. You will need to install a SIM card of that number to which you want to bind whatsapp on the tablet. On the tablet, enable Wi-Fi, enter the SIM card number that in the phone will agree and click OK. A SMS with the code will come to the phone, enter the resulting code in WhatsApp on the tablet, all activation is completed. (Do not lose the SIM card. Keep a positive balance, do not block the SIM card.). Addition: if the card will be used in an old dialer without an Internet, WhatsApp will work normally?
YES, this is perfect. (take care of the dialer from loss!) Activate always when you turn on the tablet? Not. activation 1 time. (in theory, it can fly. For example, whatsapp is crookedly updated ...) p.s. If on the tablet, there is accidentally poot. after activating WhatsApp on the tablet, create its backup, in Titanium BackUp save WhatsApp with data. additional insurance. if possible. (in case of force majeure, install WhatsApp, NOT launching, through Titanium, restore data only.)

There is another way with ROOT-rights: you need a smartphone with root and root rights on the tablet. The smartphone will need to install a SIM card of the number to which you want to bind WhatsApp on the tablet. On the smartphone, activate the program, then transfer all its data to the tablet (and do not forget to delete it from the smartphone). You can transfer data eitherusing Titanium Backupeitherwithout the help of Titanium Backup.

Neither WhatsApp nor its employees are engaged in any mailings in the system. All messages on their behalf - spam and phishing. Any messages like "Whatsapp is going to something there," or "Whatsapp is closing," or "Do something for something," is nonsense. Be careful, do not be fooled by the wiring! And you do not need to report in the subject line that spam has come to you, and “just in case” wondering if this is not serious. Remember: there are no "any cases"!

The first tick appears when your outgoing message reaches whatsapp server . When the second tick appears, it depends on the recipient's device. If the recipient of your message uses Android -the device, the second tick appears if your outgoing message has come from the server to the recipient's device. If the recipient uses iOS -the device, the second tick appears only when the user opens the program window.

You can find out whatsapp's current health status in the following ways:

• Special channel on Twitter (eng.): https://mobile.twitter.com/wa_status
  
• In the program itself: Menu-Settings-Help-Status Service.
  

Please first make sure that the problem is not related to the temporary inoperability of the WhatsApp service, and only then write to the topic.
