Excessive CPU usage in the Android App.

[Brian Moore_160997445730508]

I was wondering if anyone has noticed high CPU usage in the Android app.

I noticed that every time I used the app, my phone would get warm and the battery would drain. Using a terminal and the 'top' command, I saw that the netd process was maxing the CPU. Eventually I found that this happened whenever I opened the app and only stopped when I explicitly closed it (not just switching to another app or the home screen).

Eventually I enabled logging in my router and I found that the Reolink app attempts to make connections to p2p#.reolink.com, where # represents a number. This was detected as a possible DNS Rebind attack by my router and was blocked. It seems that the Reolink app doesn't handle this failed connection properly and just spins out of control trying to make the connection over and over.

Through further testing I found that simply putting the phone into airplane mode and opening the Reolink app will cause the same behavior. The app cannot make the connections, which causes the netd process to run out of control.

I have reported all of this to Reolink and they have said that they are unable to reproduce this, but I've tested this on my tablet as well and found the same problem.

Has anyone else encountered this?
Does anyone else want to test this out and report back? Just put your phone in airplane mode, start Reolink, and use a monitoring tool to check the CPU usage.

Hi,

pretty old post, but, the issue is stil here.
I recently bought some cameras. I'm still waiting for the parcel, delivery is planned tomorrow. OK, I downloaded the APP directly from Reolink website, installed it and ...
Immediate connections attempt to home-cdn.reolink.us and apis.reolink.com via http proxy without permission. It's unacceptable for security products.
Next - excessive DNS queries. My Android phone has no access to DNS server. It doesn't need DNS because of it's connected to private networks only. Couldn't get rid of the queries. Netd and Reolink app itself consumes 100% CPU.

I'm sorry, Reolink, but I really don't wish to share private data

Solution: using MuntashirAkon AppManager disable trackers and unwanted activities in the app (root required)
activities:

• cloud update activity
• share video activity
• support centre activity
• config cloud stream activity
• login account activity
• cloud update device activity
• facebook activity
• sign in hub activity
• google API activity

services:

• app measurement job service
• app measurement service
• firebase instance id service
• firebase messaging service

receivers:

• app measurement install referrer receiver
• app measurement receiver

providers:

• facebook init provider
• firebase init provider

App looks working, no DNS queries. We'll see tomorrow when I'll get the cameras.

Best
Petr

@reolink-fiona Hello as a non technical person - can someone advise how I setup my network configuration to address this high CPU useage which is currently making my phone unuseable...

Did you check the percentage of CPU usage?

@edwardlubowitz He needs to establish which service is causing the high processor usage. CPU usage is no longer available on Android 12 in debug mode but he can download the CPU monitor. However, this doesn't give the service usage. I told him to select wipe cache and repair appl from maintenance mode.
