老是黑屏！老是黑屏！老是黑屏！ 希望修复！！！！！ 希望改善 另外希望兼容一下低版本的iOS
I refer this to people that are caring and protectors
The app isn’t opening when I click on it. I checked if it needed an upgrade and it did but it’s still not opening when a message comes through. I have to open and close the app like 3 times before it will open the text so I can respond.
Switzerland is pushing a new surveillance ordinance that would force VPN, email, and messaging providers to verify user identities, log metadata for six months, and decrypt any data they control on demand. Privacy-focused firms warn this could end anonymous use of Swiss services and make Switzerland's surveillance powers even tougher than those in the US. This includes proton mail and Threema etc. AVOID all Swiss services from this point forward.
Every time I make a phone call, it touches my ear and turn on the camera and speakerphone. It should be designed so that it detects the ear and cancels any touch interface like the normal iphone calls.
Today I saw that Threema finally has a tool to transfer all data from one phone to another phone. This is great news for all Threema users making migration to a new device hopefully much easier.
I have got many of friends/ relatives on Threema as I believe in security and what Threema is doing about it. Don’t mind paying for it. However am seeing crashes with the system and I think it is linked to most recent update(s). Have sent just support a ticket to share these crashes…… but had sent the logs for crashes before. in the past have got decent responses. No new Threema version is available which gets to thinking if the right emphasis on security and customers are being kept in mind. Still sticking with Threema for the time being.
Love hate relationship … system keeps crashing and have to close out of app and go back in to read or listen to messages … my friend is super paranoid about privacy so won’t use any other means of communication otherwise I wouldn’t use this anymore … contacted support but to no avail …
いまのところとっても快適！ 余計なPRやいらないコンテンツもないので、シンプルに使いやすい！あと数ヶ月使ってみて、友達にも勧めたい。
So many issues for a paid app.
Because it just is.
