I have a **Moto G XT1033 with ResurrectionRemix-M-5.6.8-20160502**-falcon ROM. Yesterday night after a low battery alert I had a Whatsapp unread notification from my friend. I opened the message and found that I had a unread message from him which I remembered reading in morning. Then I observed that I was missing my conversation with him from that time onwards till I noticed this. I also observed that that **all Personal/Group Chats were also missing the entire duration's chats**. I **thought maybe Whatsapp had reverted to an Old Message backup**. But then I found that **Firefox was missing 12-15 hours worth of browsing** history. I had also observed that the **SMS which I received from the bank in the evening had disappeared**. As well **Google Play Store re-updated two applications which it had already updated** in the evening. I had also **lost some Photographs** which I took with my phone in the evening. **Call History is also missing** for the day. Google **Now showed it was last updated 20 Hours ago**. From all this it looks like **my phone Time-Travelled from morning to night**. **QUESTION:** Aside from Time-Travelling. How is this even **technically possible for the Entire phone to rollback its memory/state/data to some previous time.** I think I had noticed this behavior few months back also, when I lost some Whatsapp chats but that time I thought it must be a Whatsapp bug and did not investigate. **UPDATE1 (16th Jan 2017, 10:35PM IST)**: It happened again today (Now around 10:30 PM IST). **My phone automatically restarted**. (As if **it just time-travelled** and entered current time). Restart Vibration made me alert for expecting this scenario. As soon as the phone started, **I switched the phone to Airplane Mode** to prevent Time-Line contamination This Time I am observing the following: - Google Now Updated **8 hours ago**. - Battery **Graph is missing some time**. (Time Jump?) But **battery has decreased.** [![Battery Graph is missing some time][1]][1][![Time Jump Started around 4PM][2]][2][![enter image description here][3]][3] - Outlook is **missing the Mails** it received at around 9PM - Inbox is also **missing Mails**. - Call History looks good. Last call 8 Hours ago (2:10PM). Time Jump started around 4PM. - Whatsapp is **missing chats** which I received at around 6:30PM.

I will try to get it before I turn off Airplane Mode **Update2 (17th Jan 2017, 8:33PM IST)**: It Looks now phone has become a Serial Time Traveller. It restarted just now and the battery graph is missing two blocks of time. Whatsapp messages are missing as well.
