Yes it's completely safe I've been using it on my galaxy a06 scene I buy it and it work perfectly. But there's a catch yes it ma lag you phone but when you use havey modules like wonderland allowing thermal guardian, battery guardian to run in background. Then ya its drain a little bit battery mare nay be noticeable and may lag or ma not because galaxy a07 have significantly batter processor then a06. So Ya it should not lag
