alibaba725, since updating of OS is not an option only solution is to import your seed / private keys to some other wallet. But as far as I am aware Electrum seed will only work in Electrum, so only mobile version of this wallet can help you in case you want to recover wallet via seed.
I'm not sure that developers will fix this issue, for them problem is in outdated OS, but you can try to open thread in
Electrum GitHub.
Thanks. The mobile wallet might actually be a viable short term solution until I update OS.
