My phone (Elephone P9000 lite) behaves really strange since some time: Every now and then it freezes for about 1-2 seconds.

There are two different types of freezes:

  1. The touchscreen does not react to a tap on the screen (e.g. when playing a game, there is still movement of units, etc)
  2. Full freeze - input not working, audio stops, app "paused" (e.g. when playing a game, the movement of unit stops)

I can't identify a specific cause for the problem, i.e. it can happen when I play a game, watch a video, or listen to music (also occurs when the screen is off).

So my question is: Is there a way to find out what causes this problem?

Bonus question: Should I worry about the problem (i.e. could it indicate a hardware/software problem that could lead to a bigger issue)?

  • Phone: P9000_lite
  • Android: 6.0

Thanks in advance!

  • Sometimes, Lower-Spec devices Run out of RAM, but don't know what to remove to clear it So it will either cause a wedge/freeze, or restart zygote by accident (which restarts the phone)

The question is very general but I can give you some common reasons why phones freeze and some troubleshoot steps.

  • Do a restart by holding the power button and then press restart.
  • Find out which apps are using the most system resources and unistall them, then check if that fixes the problem. (Common apps like this are Facebook and Facebook Messenger). This app can help you fix RAM issues.
  • If you see any errors during the crashes post them in the comments or edit the original post
  • Last option would be to factory reset the phone but as the website says, all described operations you are doing at your own risk.

p.s. also, its not a good idea to post your build number on a public forum.

  • Thanks for the suggested steps (I'll try them) and the hint regarding the build number, was not aware that it's not wise to post it publicly.

  • No problem. Try them and if they help you make sure to mark my question as the answer, so other people know.

    Good general troubleshooting advice, but I disagree strongly with the build number advice. There's no particular security risk and it's useful troubleshooting info for diagnostic build specific bugs.

  • The problem is gone. But I don't know why... before I had enough time to try the suggested steps, there were no more freezes. There were updates for Facebook and Facebook Messenger, so I suspect that a previous version of one of these apps caused the problem. Therefore, I'll mark your answer as helpful since the second point would have solved the problem for sure. Thanks!
