It should be /zdʲesʲ/. Е, when used after consonants, is not pronounced /je/. Instead, it's pronouned /e/ and it changes the pronounciation of the previous consonant: it makes it soft (palatised). Ь has the same effect: it makes the preceding consonant soft.
For more info and examples, please see my answer here: https://www.duolingo.com/comment/12679198
If you have trouble pronouncing soft consonants, 'zdyes' might work as a very crude approximation.
I'm not sure how to read "nyet". «Нет» is pronounced /nʲet/ (palatised n, e, dental t). This doesn't break any rules, other words with не- are pronounced in the same way, e.g. не́фть 'oil (mineral)' is pronounced /nʲeftʲ/ (palatised n, e, f [sometimes palatised], palatised t).
On your phone there may be a language section and all you have to do is download the Russian keyboard
On a computer it's through control panel where time settings are.
On a side note if you're going to use Cyrillic you should start at memrise.com
I tried to start here and was horribly confused. After using memrise a little I find these lessons MUCH easier. It starts of teaching letters and their sounds.
Keybr.com can help you learn touch typing with Cyrillic keyboard. Just going into the site's settings and change the keyboard layout to Russian. Though you'll need to do it on your computer. Once you've added the Russian keyboard it'll appear the bar on your screen as 2-3 letters. You can click on it to switch manually or press left alt key + shift to quick change between languages.
Depends on what phone you have, in my case (samsung galaxy A5 (2017) ) next to the spacebar on the left side there is a button, hold it until you can choose the settings (gear wheel) in the settings you can choose languages, just (google russian keyboard samsung) and you will get the name of the language you have to search for, because there are more than one, download it, and now you can switch languages on the spacebar, for example, i have the german layout and the Kyrillic and if i swipe my spacebar to the left or the right i get to the each other keyboard layout :) hope i could help -Bananenmilch :з
