Serious danger? Your privacy is pretty much nonexistent when you closed-source wallet, since you're connected to their server and it's likely they log everything (where there's no way to prove it's true or false).
But Coinomi does allow you to change the server it talks to (on the mobile version). Don't trust them for privacy, use your own server.
You can actually install a sniffer on your Wi-Fi and see that yes, once you change it it never talks back to them. On mine it has not pinged back for months except for update checks.

TBH i completely forget about it, but AFAIK by default you're connected to their server and there are very few people who bother change it (since usually people who bother do this would use open-source wallet instead)
Yes, by default you connect to their servers. All wallets do that.
But with some open source wallets you can't change easily, or at all.
With mycelium, you have to change the source and recompile and with green you can change SPV only do it on android.
Some like electrum are quick and easy to change. Others, not so much.
So keeping all that in mind, the general consensus about Coinomi Wallet is..... "yes, I advise you to use it" or "no, I advise you to not use it"
I will say for me I consider any amount in a hot wallet on a phone to be funds I do not think are safe and could loose at any moment, no matter what wallet it is.
So, I would say if you want a multicoin / multitoken wallet on your phone (or desktop) holding hot funds that are not going to make a difference in your life if you loose them then yes I advise you to use it.
If you want to store your life savings on BTC I would tell you to use a hardware wallet with at least 2 of 3 multisig.
Somewhere between those two amounts is your comfort factor.
We are anonymous here, I don't know who you are. You could be Bill Gates so your comfort amount in a hot wallet could be 15000BTC because that is your petty cash.
Or you could be living paycheck to paycheck in a very poor area and loosing anything over $20.00 is going to mean you don't eat tomorrow.
So, although it is a bit of a circle I say yes use it, but no don't use it. Depends on the use.
