Since we are on the topic of signal.. im not tech saviie but i have read lots of blogs and people about how secure is the signal protocol. My question is .. how can i be sure that the protocol is implemented as the open source code shows? Please correct me if im wrong but from what i read on their website the apk they provide has the capability to update itself at anytime. So what stops them to change how it works with an update? is it posible to build the apk yourself and stop the ability to update?

Just like any foss project, there some level of trust if you are going with the main distribution. In theory you are correct that not much is stopping them from releasing a malicious update, but because it is open source, soon enough people would notice that either they released new code that is malicious, or that the new version does not match the source code. That kind of scenario is known as a supply chain attack.
Since the code is open, you can literally read it for yourself to see exactly what the apk does. You can also fork it and modify it however you like, just like the creator of Molly did (Molly is a fork of the Signal client that adds some security features)
It's a centralized, US-based service running on AWS, that's not self-hostable, requires phone numbers, and you have no idea what code their server is running.
Whether the app is you use for it is open source entirely irrelevant for them building social network graphs, considering they have your real identity via phone numbers.
If the answer is "I just trust them", then you're not doing security correctly.
Right now, for the wider population, it it a heaven sent option compared to Whatsapp, FB messenger etc. Break those bonds first and keep the wheel turning.
crazy that no one's posted the dessalines article yet https://github.com/dessalines/essays/blob/main/why_not_signal.md
EDIT: just to have it here in case anyone even cares, i put my thoughts on the essay later on in the thread

With the phone number, no; and since there's no Signal usage without a phone number, well…. Also, I think somewhere on their website (or some place) they talked about burner phones as if it's a universal phenomena.
Signal has felt "out of place" to me. Odd. It doesn't fit in, doesn't make sense if I think a bit farther about it.
I hope something decentralised comes out of Signal protocol minus the need for a phone number.
SimpleX uses Signal tech AFAIK but without requiring phone number or email address.
