I installed Version 4.2.1b3 (20150416) (10053) of the beta on my Asus MeMO Pad 7 (ME176CX-A1-RD, Model K013, Android 4.4.2) and 1Password no longer crashes. All items sync'd without issue.
It's really great to hear sync on your MeMO Pad 7 works on our latest 1Password beta. We appreciate you reaching out to us to let us know our solution for the Intel crash works on your device. Thank you.
