Gosh please revert to showing the name instead of mobile numbers. Its more problematic since the names that we use can be a nickname or maybe initials only. If we do not like our face to be there, we can use a different picture. But our mobile numbers may be tied to bank accounts, email and others for One Time Passwords etc. My mobile number is a personal information I do not want to be shared. I feel so unsafe in Viber right now.
