Viber must add chat export history locally on format like PDF, excel, word etc I do need this future, you Will lose ALL Viber history if you reset you phone! Regular interruptions in audio communication, just another spy program ... on the same router in the local network, optics .... I can not have a conversation with satisfactory quality, failed in the only thing for which Viber is installed. Peer to Peer (P2P) does not work, why it has to go 20+ hops! more bad than good things, time to delete
