Cons
Con Needs access to your phone number and contacts to work
Con Single device
Signal can only be registered to one mobile device at a time. But you can link Signal to Signal Desktop.
Con Unreliable notifications
Sometimes messages won't be received if the Signal app has been closed for a long time or hasn't been opened after booting the device.
Con Servers hosted in the US
A security risk due to National Security letters, which require giving up data to the US state, and making it illegal to disclose that.
Con If SMS/MMS imported, other apps can't read SMS
For those using Join, Pushbullet, or similar apps to send and receive SMS/MMS from web or desktop, putting your SMS in Signal somehow breaks this functionally. The dev is aware but plans to remedy the situation have not been named a priority.
Con Cannot work w\o Google services
Signal relies on Google services for push notifications so although it is encrypted and open source it needs proprietary component to work. That means you can't use Signal on some custom Android ROM (preferably rooted for full control) without Google apps installed.
Con Uses message mirroring
Con The website has performance issues
The site tends to lag and file uploads can sometimes fail.
Con Might be removed anytime
Google has a tendency to quickly shut down or abandon services that don't perform well. Google Photos might run the risk of being discontinued if the user base of the app doesn't meet certain criteria.
Con The web version lacks certain features available on mobile apps
Con Doesn't backup in the background
For iOS devices
Con Not a lot of free storage space for high-res content
While there's a free unlimited storage plan, it's limited to 16 megapixel images and 1080p videos. Uploading full-resolution content, if you opt out of free unlimited storage plan, is limited to 15GB that comes with a Google account which is shared across all Google services. Increasing that storage space costs about $10/mo per 1TB of storage.
Con Files may be compressed if you're using the unlimited storage option
All images exceeding 16MP and videos exceeding 1080p will automatically be compressed to that size or lower. Meaning high-res images and videos won't work with the unlimited storage option.
