[Q] Interesting wakelocks between Galaxy Nexus and Nexus 7, location settings / maps.

Hi all,
Posting this here because it's the device in question and no one answered over at general Android Q&A and Reddit hasn't been able to help.
Long time since I posted here but I'm at the limit of what I can effectively do so I'm looking for some help here and I believe this is a problem with the OS itself and how it handles shared settings and even with the Maps application, rather than being device specific.
First, specs:
Samsung Galaxy Nexus (UK HSDPA+) running Jelly Bean 4.1.1, completely stock and unrooted.
Asus Nexus 7 (also UK, though I'm not sure this makes a difference as the N7 has no GSM radio), Jelly Bean 4.1.1, completely stock and unrooted.
All apps are the latest versions.
Background: This problem has only existed as long as I have had the Nexus 7 in addition to the Galaxy Nexus. I'm 90% sure that the issue relates to the fact that I have location reporting enabled on the GNex and NOT on the Nexus 7. I'm signed into both devices with the same Google account. Occasionally one or the other will pick up the opposite one's settings with regards to location sharing, a PITA.
The problem: Ridiculous amounts of wakelocks caused by the Play Store, Maps and the Launcher. As you can see here (BetterBatteryStats pic included). imgur . com/ a/yz83J (I can't post the hyperlink because I've not posted 10 times yet.) This only seems to cause a problem on the Galaxy Nexus. I haven't noticed wakelocks or battery drain on the Nexus 7.
This absolutely drains my battery. If I kill off Play Store and Maps and clear all cache data then the wakelocks stop for a while.
Two days ago I was forced to uninstall all updates to Maps and return it to the default version and update it again as killing the process or even rebooting the phone failed to stop the wakelocks. This didn't stop the wakelocks but out of curiosity I just told the device to completely stop updating my location on it's own. This has completely stopped the wakelocks and the resulting power drain..
The catch: I'd really rather not have to leave location updating off to resolve this. It's only been happening since I got the Nexus 7 and I'm trying to get that to NOT report my location and the GNex to report. The reason I have it turned off is that I have it on train WiFi a lot, which displays my location as wherever the connection terminates. E.g. for an entire journey from London to the north, my history for that day shows that I travelled the distance between every point on the route that my phone reported and London Euston station where the Nexus 7 was connected, in about 1 second. This led to my location history being an utter mess!
The question: Any ideas on getting this working as intended? If I can provide any more data let me know. I've already run an ADB output of my alarm manager stats and it's showing the same as the BetterBatteryStats info.

The apps will constantly try to refresh maybe because it's trying to receive data like notifications.
You can try JuiceDefender or Greenpower or apps like that in order to limit how often a certain app syncs. Some ROMs also have such a feature if i'm not wrong.
If all else fails try a factory reset and see if the problem is fixed. Did you do a full wipe before changing to jb from ics? Maybe that could cause problems.

Thanks for the reply.
No I did not do a full wipe because the update to JB was delivered OTA when Google released them, these devices are completely stock. I believe the issue is that the GNex is attempting to update the location, the Google account is reading the Nexus 7 setting of not updating the location, then the response is bouncing back to the GNex, which insists it does need to update the location, etc.
As I said, I've temporarily solved this by stopping the phone updating it's location at all, however this isn't the best solution and since I've found the cause, I'm not convinced a factory reset or even reflashing the stock ROM will help. I'm pretty sure this is a deep OS issue, using the same Google account across 2 devices is great, until you want them to have different settings.
I'm probably gonna report it on code.google.com, but I very much doubt I'll get a response.

[Q] GS3 cannot connect to Google account

As a new member of the XDA forums, I'd just like to point out the fact that I have searched the site and internet extensively with no success.
That said, allow me to introduce my problem.
AT&T Galaxy S3 w/ CM 10.1 is REFUSING to connect to ANY Google account. The problem occurred while on stock Touch Wiz (w/ root). Was solved (temporarily) by flashing CM 10.1. To my dismay, the problem returned a day after I flashed CM 10.1. I have attempted to fix the problem by doing the following.
-YouTube sign in trick
-Hard reset with and without SIM.
-Flashing phone back to stock.
Others seem to be able to find solutions for the same problem, but their solutions are not working for me.

Can you sign in on a computer at all? I would check settings in google and in gmail to see what is up.

[Q] Samsung Galaxy Note 2 (GT-N7100) apps keep rearranging!

I have noticed my Samsung Galaxy Note 2 (GT-N7100) randomly rearranges my apps every once in a while. Does anyone know if this is a fault on this particular device or if it is a common problem. Also how do I rectify this reoccurring problem. Is there any way I can prevent this from happening.
I am on Vodafone UK running on Android Version 4.1.1 (apparently this is not the latest version but my device will not connect to kies on my laptop, it says the software on the laptop is not the latest but wont let me update it.)
Your help will be much appreciated.
Thank you.

[Q] wifi disconnects after 10 sec. when battery is bellow 70%

Hi All.
Having a weird problem here with My wifi om my new galaxy note 8 (n5110). After updating to latest software version i loose wifi connection after about 10 seconds but only if battery level is 70 or bellow. If the charger is plugged in wifi works perfectly again. What could be the reason for this?

I assume you did not do a factory reset after doing the firmware update to 4.4.2
Once you do that it will clear your settings for the 4.4.2 to operate properly. You will need to sync your settings, via google / samsung cloud or kies.
Google should download your apps once you complete the initial setup, so be sure to complete all the setup when the screens are available.
Some apps may need to be restored from backup or installed from where ever you got them.

Thank you very much for your reply sir. I did a factory reset after the update, still the same behaviour. Tried resetting again with no change.

After a third restore, the problem seems to have solved itself.

Issues with apps over WiFi after upgrading to Android 9

Hi. At the start of December, I upgraded my Mi A2 Lite to Android 9 and ever since then I have been facing issues with a few apps over WiFi. The following apps are being affected:
- YouTube
- Twitter
- Facebook
- WhatsApp
- Chrome
*These issues are only on my WiFi. On 4G or any other WiFi these issues don't happen*
The issue with Facebook and Twitter is the same. Both won't load any new feed and behave as if my WiFi is not turned on. YouTube only works at times, other times it would just keep loading and nothing would happen. Sending images or videos on WhatsApp is impossible now. It even has troubles making the backup to Google Drive on my WiFi. As for Chrome the issue is that sometimes even though WiFi is turned on, it would not load any page and just say that I'm not connected to internet. I've been reading other people's threads online and even emailed Xiaomi and Google. I tried the steps (hardware test etc) as told in the email by Xiaomi but that has not helped. Some said that using WiFi and Bluetooth at the same time caused this issue but I have used WiFi with bluetooth turned off yet the issue is still there. Now if this was a WiFi issue then I would have contacted my provider but with the same WiFi connection I have not faced a single issue on any other mobile devices and laptops. As for my WiFi I can't seem to change it from ipv6 to ipv4 (or I just don't know how to). If anybody has faced this issue and knows how to solve it then please help, It would be greatly appreciated. Thank you for your time.

Have you tried disabling Bluetooth and then reconnecting to the WiFi in question? Having both enabled at the same time causes WiFi speed transfers to be really bad, it's an already reported Pie bug.

Btw, can u see 5ghz wifi networks?
Cause i can and have same problem with slow wifi+bluetooth

Yes I have turned Bluetooth off and used WiFi like that but the issue is still there with all the apps mentioned

Any update on this? I'm having the same issue. Using a VPN seems to solve the problem but the connection is slower.

I am facing the same problem on my A2 lite Android One Pie. Even the further upgrades including March upgrade did not resolve the issue. It really sucks.
Has anyone found any solution?
Is MI even concerned or acknowledges the issue?
Is there a way to go back to Android 8?

Hello Dear Sajid Abid,
Good Day !
1st Remember One Thing. Downgrade Is Not A Easy Task, Downgrading Has Also A SIM Issue Problem,.But If You Still Want To Go Back Your Mobile Device From Pie To Oreo You Need To Unlock The Boot-Loader (Off-Course Unlocking Boot-Loader Will Void Warranty) Then Download Stock Oreo (From MIUI Forum) And Flash It With The Help Of IMFlash Tool. After Successfully Ported The Stock Oreo Rom You Can Close The Boot-Loader.
All Instructions/Steps Can Be Easily Found On A2 Lite Forum.
Here Is The Link Which Can Help For Resolving SIM Issue Problem.

Have A Nice Day.
Thanks,
