Still exists in alpha 1.0.3.0. Reconfirmed in LG G2, Samsung Galaxy S4 Active (OS 5.0 Lollipop), LG G3 (OS 6.0 Marshmallow).
Hope this issue is still in progress and see it fixed near update (Maybe 0.16.0). Still exists in 0.16.0 alpha build 1.
Unfortunately, the bug still exists in 0.15.6. This bug has been effected since 0.12.0 to all versions (including development versions) including 0.15.6.
I'm not the reporter, but noticed a comment through my e-mail, so adding it instead of the reporter. Still bug exists in version 0.15.4. Reconfirmed in LG G2, Samsung Galaxy S4 Active (All devices Android OS: Lollipop).
I have experimented about this bug... Does it happen only if the world is created pre 0.9.0 (Before infinite world released)? Also, my world is created since 0.6.0, snowy biome appears to be raining instead of snowing... (Also, weather error, I guess...) All region is raining. Unfortunately, this bug still exists in v0.14.0. Will this bug disappear even I change my world to infinite...? (But, still I don't want to. Guess I should backup my world and test again.)
I have a same problem in android device. I checked this bug in LG G2. I think this bug happened the first time on 0.12.0 beta versions for me. Need to be fixed ASAP.
In my situation, LG G3 (LG-F400S / OS 6.0 Marshmallow) happens with this issue. Cannot enter MCPE without any network connection. Only available when network is connected to phone. Still, for example, Wi-Fi connected, but if isn't connect to Internet, crashes. Checked in alpha v1.0.3.0. Need to be fixed ASAP.
