Get back phone contacts

Sherif Moharram , I do not own this phone, if you have a backup of all your contacts into your pc/laptop you can retrieve there or if contacts are synced with any google account, then use 'Sync Contacts' to get back all the contacts, use the link below for more info. and instruction. There is other after market software which claims it can restore deleted contacts if you want to try, do a search(How to Recover Deleted Contacts on HTC One M7) and quite a few will pop up. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
