What exactly are coins or tokens you are planning to hold in your wallet?
Unless I missed it, I'm surprised I had to scroll so far for this question to be asked.
@OP, for both security and amount of coins that are available in one wallet, hardware is probably ultimately the best option (Trezor or Ledger should both work fine with android).
If you don't want to go down the route of using hardware, most of the suggestions above are good - each have their flaws though (especially in the scope of currencies they offer) which might be a drawback for you.
why these trust wallets are being hacked??
They're used A LOT, especially by newbies so they're lucrative for an attacker to hack.
They're also closed source which means the wallet is developed by one central team and only they have access to the code. Wallets like electrum and bitcoin core do well because anyone can see their code, and, if they find a bug can report it and most can even trace where the error might be in the code allowing a developer of the project just to change it as it's reported.
Most malicious problems found in any software are generally patched within a week or so (for closed source projects) or a few minutes-hours (for open source projects) so a lot of attackers try to sell vulnerabilities and execute them close together to try to increase the number of devices they can target before it's patched.
