Network Signal Drop after installing Facebook hello Caller id

Hi, i don't know if it is the right thread but i'm facing an annoying issue on my LG D855 (Fulmics 5.3 custom ROM), after i install Facebook Hello Dialer App (Caller ID & Block) i have a constant network signal drops, like every 2 secondes, and every time i try to place a call with or without the app.

The app itself works fine to identify and fetch peoples data (over wifi of course). I can't figure out the problem, i tried switching between network modes (2g/3g/4g/auto), disabled/enabled sync optimisation, but nothing resolved.

The app was sideloaded since it is unvailable here in Algeria, maybe be because of network bands in my country (slightly different from US ones, despite i don't see relevance here), but i installed it on a bunch of other smartphones and all went ok (1st gen Samsung Galaxy A3, LG L Bello, and even a chiness clone of the Hisense u970) (all on stock roms).

If someone can help me it would be nice.
Thank you.

Random wifi drop (disconnect + connect) [Solved]

I got random wifi drop (disconnect + connect) with my S7 in my home network, sometimes 1 time in 2hrs, sometimes 4-5 times per hour. This is annoying since the S7 vibrate when losing wifi, and make sound when conecting. I tried every solution availables on xda, android central, and didn't find a solution that fix my problem.
In my case, the issue is on the 2.4 band and also on the 5.0 band. My router is a Dlink DIR-868L, updated to the latest firmware. All my other devices, including Galaxy Tab S2 have no issues.
I tried:

- turning off Bluetooth (also the scanning in location)
- changing channel on router
- turn off smart switch
- factory reset
- ...

In last resort, i plugged in my old router (DIR-628) on the 2.4 band and got no issue, so i looked to find wich parameter on my DIR-868L is the curlpit.

So, i found that changing the channel width from (Auto 20/40) to 20 solve my issue, no drop since the last 15 hours.

Little tip: I used and app called "WiFi Logs" to monitor my wifi connection.

Hope Samsung will fix the firmware soon!

Deep sleep battery percentage drop?

Hey everyone,

I currently have 6.0.1 installed on my XT1575. I've had previous versions of android such as 6.0 and different ports of 6.0.1. With all of these, when the phone is in deep sleep, I lose about 8-12% of battery life. Is this common for everyone? I've followed many guides to improve battery life that encompass using greenify, amplify, etc. I've currently got all those running to help with the battery. However, I still get this bad drainage of battery when I go to sleep. I've turned off all location options, wifi, wifi scanning, etc. When I check BBS, there are alarming wakelocks at all. The phone seems to be asleep, yet, it drains battery. Coming from an LG G2, I'm used to the phone only using 1-2% of battery while it is asleep.

What are you guys experiencing? And have you tried anything to improve this?
