Its seems there are a lot of scams going around so no links to websites please..
I know of Coinomi as a wallet but I'm not sure it supports Electrum..?
It depends which version of Electrum you are using. If you are using a standard non-Segwit Electrum wallet -- with addresses like 1xxxxxxx -- then Coinomi should work for you. I do not believe that P2SH (3xxxxxxx) or Bech32 (bcxxxxxxx) addresses are supported at this time.
Personally, I'm waiting until the dust blows over. I think BTG will probably get pumped sometime down the road, so I'm just leaving them where they are. When I do sweep the private keys into a BTG wallet, I will make sure to send my BTC to new addresses first.
At this point, if Coinomi isn't an option, I would go with the official Core client.
