Obviously there are still alot of dev work required on the Iota wallet, but fortunately I used the Andriod wallet to get my funds transfer and - hallelujah- it worked 100%.
I think that mobile wallets are a non negotiable for any crypto.
Not sure what problems you have encountered but yes, iota is extremely young right now and that is one of its beauties - it is unstable, sure. But the price as a result is cheaper and undervalued unlike most other altcoins.
The only problem i had with their actual wallet was balance disappearing, which is fixed by attaching the address to the tangle multiple times.
Mobile wallets aren't as secure, it's best to stick to their official wallet.
