So I had a nexus 5x (android) and I was using Whatsapp. A lot. A couple of days ago my phone crashed and I can't make it start, eventually I switched it for an iPhone 6plus, when I downloaded Whatsapp again I noticed that all my past conversations were completely gone. I didn't back my conversations on my iCloud because I didn't have an iPhone device at that time.
I don't know how or if possible to recover the messages but I know that Whatsapp backed up my messages (it auto backed it every night at 2:00 am) but I don't know how to access the backed conversations. The only way whatsapp would let me recover conversations is via iCloud but i didn't have an iPhone so its empty. Can I recover my lost conversations? Should I run it on another android device? Hope someone would be able to help me.
