How can I find my last messges/calls i've sent. Is there any log on this phone, c905? I've deleted off my messges bit. Also I need to lock my phone as it keeps going off in my pocket, how do i do that?

It can be quite annoying and sometimes even a big problem for you when you accidentally lose your call logs or call history. This is especially true when there is a number on your call history that just happens to be important but you somehow forgot to save in your contact list or you were unable to do so before the call logs vanished.
The question is: is it possible to recover these deleted call logs? I am going to explore this issue at greater length and offer you a solution if you ever lost your call logs.
If you had backed up your call history, you can recover deleted call logs from ZTE phones via backup.
In addition, you had no back up your call history, then there is only one way to get them back. You have to use a third-party data recovery tool to get them.
Step1: Download and Launch Fonedog data recovery.
Step2: Select call log files to scan
Step3: Preview and Recover deleted call logs
