I'm facing some issues in my lenovo vibe p1m mobile: 1. Automatically switch off 2. Call log of some contacts are not displaying in dialier but we open the contact and see the call log of the contact then it is available there. 3. Automatically going to silence mode or vibration mode 4. Automatic power save mode on without touching the toggle key provided for the same 5. Not able to access or write on SD card through the third party apps For your kind information I had updated the 1357 MB S027_151127_16G_ROW update immediately after I'd purchased
