Ratings and Reviews
BOOK DOOR TO SIGNAL APP EXPOSED
The service has now become pretty much useless. I no longer receive an audible or visual notice when people send me a message. Only once I click on the Signal icon do the alerts actually come in. Now I have to keep opening the app to check for messages. This is not the case with other messaging platforms. Yes, I allow full permissions for Signal.
Additionally, I came here to update, but I dare not as Signal now allows third party stickers/ads. This now opens up a backdoor for hackers. Soon, Signal will shut down all users that don’t update.
I use to boast how secure Signal was. Obviously the developers of Signal had long term plans to monetize their once highly secure communication service?
What do we expect for Free anyway? Obviously Signal’s original Mission Statement has changed. Third party advertising has now become a security concern.
I’m only here as a means to communicate with other hi level parties who feel safe using this app. That’s now going to change as word gets out that a backdoor for advertising has been installed in Signal’s app.
Though no communication service is bullet proof, adding an additional layer of script to monetize Signal, (in my opinion) opens up a serious security breach that will eventually be exploited by hackers.
Signal is not the only game in town. Once I get all of my contacts to migrate to a more secure app, I’ll be uninstalling Signal, as it doesn't alert me any more anyway.
Nightmare editing messages on my iPhone XR
I don’t know if this disfunction is related to the particular phone (iPhone XR) that I am using Signal on now or if it is the same on other phones, but the “cursor” control on Signal is a disaster now. It is a nightmare trying to move the cursor to where you want it, or to highlight a specific section of your message. I am completely unable to move the cursor more than a couple lines away from its current location at a time (and the text window doesn’t extend to more than 4 lines tall), so i have to scroll a couple lines away, click somewhere to move the cursor in the direction of where i want it to go, and repeat over and over again until it finally gets there. If i try to move it further than that, the window just jumps back to the area where it is currently located and moves it to some random location nearby.
Highlighting a portion of your message is impossible; it jumps from one end of the message to the other and will not allow you to scroll slowly to where you want to stop highlighting. It is so stupid ~ I recommend typing messages in another app and then pasting it into signal when you are done.
Also, FYI, if you want to copy text from a signal message, hold your finger on the message and then click on the little icon at the bottom of the screen that looks like two pieces of paper - nothing will ever appear that says “copy”.
Developer Response ,
This bug is resolved in the most recent version of the application.
Lots of features (Gify, stickers, reacts, self destructing messages), but it requires you to give out your phone number to everyone you talk to, does not allow specifying a different server, and beyond those privacy concerns, it has gone downhill lately in terms of usability and security as well.
It now it forces a PIN even if you don’t want one. Private keys are sent through the server to enable moving from one device to another. Signal used to store private keys in hardware and it was impossible to export them. This ensured that nobody could ever covertly get your key. They removed this security protection and do not even provide an option to use the more secure key storage. The Signal developers could have enabled a smooth device transfer and kept the keys in hardware by having the old key sign the new one so others will 1.) know that the new key is new 2.) know that it is legitimate, and 3.) be able to verify the move using another communication channel if they suspect something is amiss. The Signal developers decided against this.
Given the developers’ recent decisions, and their unwillingness to allow people to use their system without divulging their phone numbers, earns this app 3 stars. If they put more focus on privacy, security, and allowed connecting to private servers, it could easily be a 5-star app.

Open Whisper Systems, a collective of developers that work for secure your communications, has merged the famous secure chat app Secure Text and Call app RedPhone into one app: Signal.
Signal is already available for iOS, but the Android app was divided into two parts: TextSecure and RedPhone. Open Whisper Systems wants with Signal to put all secure communications in one app. Signal is completely open source, is maintained by many security experts and even has the approval of whistleblower Edward Snowden.
This is what you can do with the Signal app
Signal uses end-to-end encryption, ensuring that messages can be decrypted only by you and your partner. TextSecure servers have no access to your chats or metadata such as the title and composition of a group. Signal uses your phone number and requires no additional logins, usernames, passwords or PINs. It works much the same as WhatsApp: your phone number is how you can be reached.
In addition, it is possible to make secure calls with Signal. This works through VoIP; calls over the Internet. When the call is set up an encrypted connection, which is secured by end-to-end encryption. During our testing, calling with Signal worked good, but especially if using a 4G or WiFi connection.
Open Whisper Systems earns money through donations and investments from privacy advocates. This allows a small team of developers on a freelance basis to work on the app, and there are many enthusiastic developers who help improve the code of the app and quickly fix potential vulnerabilities.
