Hi,
after updating, Mycelium tells me that my Android 2.2 phone is unsupported due to a bug in random number creation on that OS version.
Could you share some technical details so I can estimate my risk? (or did I miss an announcement somewhere?)
Since I'll be switching to a new phone in a few weeks anyway (Christmas is just around the corner) I could probably live with avoiding to create new transactions and just initializing from the backup once I have the new phone.

there is a bug that leads to android 2.2 being unable to multiply big numbers _sometimes_. previously this mostly just lead to wrong TX being generated, that were rejected by the network. annoying, but no huge risk.

now with HD wallets it is possible to generate a wrong address from a seed that has no matching private key. this is bad. therefore, quit using it

we had one case where a user reported this, and we strongly think android 2.2 was the reason.

Mycelium warned me that there will be no further updates for my Android version.
So using Mycelium HD wallet functionality with this old Android is not recommended now? I can use old pre-HD address pairs.
