Read the post above you.Is this Normal or my phone has problems ?
Mine seems to require 200mb free on the storage "screen" to allow me to install any type of app."Internal storage" and "phone storage" being different and yet both being the same size (but with different amounts free) seems very odd. If they were different sizes I'd assume you had one of those odd phones that still uses distinct /data and /sdcard partitions (normal for android versions older than 4.0, but still used by some budget Chinese models for reasons nobody can understand), but both claiming 16 GB is funny.
There's a little app in the Play Store called Storage Truth. It's very small, so hopefully you'll be able to install it. If so, can you run it and post the output here? That will give a clear picture of what your actual storage situation is - the system menus, in trying to be "user friendly", are often very unclear as to what's actually going on (what are "internal storage" and "phone storage" for example?)
The weird thing is the coloured bar in your "internal storage" results: it shows the green (Apps) part as smaller than the grey (Available), but below that says that Apps is almost 6 GB and available is under 700 MB. If installing an app would leave you less than some pre-defined limit, which is commonly 500 MB, available then the app will refuse to install, so if you are trying to install a large app that could be a problem if the "693 MB available" is the reality, which I suspect may be the case. But if that is the problem you should be able to install Storage Truth as that is tiny.

I don't have 6gb of apps installed i think it's fake my phone Is X-BO Chinese productEek! /data is the partition that apps and app data live in, and it's tiny! In fact I've not seen such a small /data partition in several years. If that's the setup then it explains your problem all right (you've been sold a very badly specified/set-up device).
But then how was the previous image claiming that there were 6GB of apps installed? Even if this device let's you move them to sd that only moves part of the app, so you couldn't install that much. Was there more output from storage truth (if you scroll down)?
Bear in mind that you cannot genuinely expand RAM. You can use other storage as "swap space", which is what that app is for, but frankly I don't see any point: other storage (internal or SD) is much slower than RAM, so if swapping is used heavily it will slow the phone, and if it isn't then you didn't need it in the first place. Personally I'd just let Android manage the RAM itself (you should not have a lot of free RAM, that's not the way that Linux memory management works).
in previous i have 1.5 gb ram. using roeshoft ram expander my ram converted into 4gb using sd card. after this, i wont found any lag or slow. hd games are works fine without lag. phone is not laggy. sorry for my english.
You ended-up with 4GB of SD card swap, not 4GB of RAM, though...a much, much slower memory medium.
Apples (SD card) and oranges (actual RAM)...
No worries, @munemsahariar--I don't doubt that the app you mentioned does help your device run better, but I just wanted to make sure that folks understood that no app can actually give you more RAM since that's a physical resource.
A RAM "expander" does not give you more RAM--it's giving you more swapping space on much slower external memory. RAM itself is very fast, but limited in size. External memory is much slower, relative to RAM, but is obviously larger. Another device with larger, true/actual RAM will significantly outperform a device running a RAM "expander".
Hope that helps .
