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.
