Few questions regarding my phone

[menisam]

I went to the settings -> about phone

1. phone number - unknown.  why?

2. model name - I can google, but model code - nothing comes up, why? (SM-G990ELGGSKA)

3. IMS registration status is not registred - why and what is it (I read on google some protocol but what does it practically do)?

4.  if I registed a device in the account, does it mean it is registed for all purpouses or do I need to do something more?

5. is it normal my phone is next to the router and have 107-113 dbm and 30 asu google suggest I have just one or two connection lines, but it shows strong signal and I hear call well, so what's going on? or maybe it's the sim fault?

6. I have "Your account doesn’t have a password because it was created using your Google account. Set a password now to secure your account." - message, they say they sent me an email, and i follow it and put each time a new password, but the message to register the password doesn't change no matter how many times I have changed the password

thank a lot!!

When you first setup your phone and login and your Samsung account your phone will be registered to it, you can check the status of your registered devices by navigating to your Samsung account then devices

thanks it's says it's registered there. 

I don't want to grind this too much sort of speak. in the past there was register you device on the company's website and it was even necessary for warranty, especially out of the country. so this is the same, when it's register on samsung account, it takes the serial number automatically? 

thanks!

The registration process is automatic when you sign into your Samsung account, but you can always check the status of your warranty in the Samsung Members app please let me know if you need anything else

[menisam]

thank you and sorry for the late response. 

how can I see the warranty in the app?

[user_ams007]

You can check the Warranty information in the Members application, under Support, or if you have Samsung Care please go to this website and enter your Imei number or serial number

where is support can I see it? (I don't have care)

[user_ams007]

Open up members app and it's located on the bottom left side

[menisam]

thanks, I knew where is the support , but after that, where is the warranty?

I also need to get back to this issue: 

"NO PASSWORD SET

Your account doesn’t have a password because it was created using your Google account. Set a password now to secure your account.  "

this is when I sign in from chrome, in a non incognito mode. seems like somehow google affects it.  because on edge and incognito , I don't have the problem

Open up your settings on your device and on the Top you should see your Samsung account then tap the that and check your password for your Samsung account
