@MojangSupport hey just wonderjng...is it possible to get back my world after i accidentally deleted it in minecraft bedrock in android please...help me

Minecraft worlds are stored locally on your device; if the world has been deleted and there are no backups of that world, unfortunately, you won't be able to recover your world. More info about this can be found here: msft.it/6019w6TzH. ^FF

hmm that bad... btw i have some problem with bedrock im playing with... 1. for some reason i cant hear the song when played in jukebox 2. the wither boss....please remove when dash attack destroyed the block.. cause it lag so much. for player with bad phone..its suck

For your first issue, check your Audio settings in-game and make sure "Jukebox/Note Blocks" is turned up. For your second issue, I don't think I fully understand the issue. Can you explain a bit more about when this lag happens? ^NS

1.yeah the sound all up but still dont hear any 2. what i mean is wither boss have this attack when on 2phase he can do dash attact its does look cool but the problem is it can destroyed a block its hard enough to attack it using mobile plus destroyed block from dash it suck

Hm, that first issue may be a bug. Please search our bug tracker for a matching report: msft.it/6014w6bhp. For the Wither, this sounds like how the fight is supposed to go. If it's taxing on your device, I would first recommend adjusting your settings for performance! ^NS

for the wither its still bad after lowered the quality and all those stuff its ok but when im in the chunk with the wither plus the entity block that mas been broken by the wither its start to lag again i like the dash mechanic but not breaking the block mechanic
