For me personally electrum never really worked as expected on android - it was constantly crashing at the most inconvenient places.
Try using the desktop version of Electrum.

try to interpret what LoyceV is saying about which is better between Electrum and Blue Wallet.
Electrum often crashes for me too, on my desktop. It happens right after broadcasting a transaction from a hardware wallet, and I've reproduced it with different versions on different (Linux) systems.
When it crashes, the transaction may or may not have been sent right before it crashed.
