Title: New 4.2.1 issue?
Post by: martyh on December 04, 2012, 12:56:35 PM
Hello....

My N7 was updated toward the end of last week to 4.2.1.

Since then, the N7 has spontaneously rebooted at least 10 times that I am aware of. It will reboot in the middle of a game (CrossMe Color), while I'm in a web browser (Chrome), and once when I was simply swiping from one home page to another.

Anyone else experiencing this?

Martyh, sorry to hear of your Nexus woes. Personally I've had zero issues since updating to Android 4.2.1, it could be a rogue application causing this issue so.... you could try clearing their cache, uninstalling some apps or worse case scenario would be a factory data reset...

JayJ,

If the reboots were happening only while I was in the same app each time, or doing the same thing, then I could see where the problem lies -- and uninstall and reinstall the app, or even delete it completely, or contact whomever to report the prob. But the reboots are completely inconsistent, alas....

Cheers,

I have a similar problem Marty. Mine is rebooting at least once a day. I figure a new update will be coming soon so I am just staying as patient as I can.

So this issue has been possibly linked to using HD widgets. Can anybody confirm or deny that?

Generally random reboots come from the ram being filled up. Check to see what all apps are running and how big they are. Check your cached process and see what's happening there. You can also clear all of your cached process and that may help.

I have HD Widgets installed, but then bjs229 is having the same/similar prob and doesn't have the app installed. So, who can say....

Thanx for the suggestion, fxsarge, I'll keep an eye on what apps are running. I think I read that the 4.2 update allows you to clear cache for all the apps at one time, rather than having to access each app individually.

Speaking of the updates: I find I'm now having to login again whenever I access an Amazon app. This was happening after 4.2, but then Amazon released an update to their Appstore app. Now with 4.2.1, I'm now having to login again every new session.

If you check all the current reviews for HD Widgets on the play store, a lot of nex7 users are complaining about this. Some say that turning off gps helps. It's apparently a problem with Googles lock widgets and should be addressed in the next update. However, HD Widgets is the worst hit on this. There are some threads on the xda dev site. I would disable until an update on os or app if it gets too aggravating. Hope it's fixed soon. Sarge is correct on the lack of free mem causing problems, but that is usually a force close. I've had one reboot so far. Knock on head.

Scroll down to comment six for another possible solution.
Google issue thread.

Recap: turn off gps and all location services. Or per comment nine, disable location in HD Widgets only.
Let us know!

My GPS is much more important to me than another clock and the weather that I am already out in.

Thanx for this link... I read comment six, and then kept on reading. I don't currently use GPS so that's already turned off, so l disabled the auto loc function in HD Widgets. We shall see how it goes now....

Thanx again.

I run HD WIDGETS on my N7 and have never had a crash.

Also run it on my Nexus 10 and S3 without issue.

Granted, but for those who are experiencing reboots, turning off location in the widgets may be a solution. It may have to do with the way the non gps location works, which could be different for the isp or router that is used. Or however that system works. Whatever the crash fault, hope it's fixed on the next update.

The clock widget lock screen I use, I had to input location manually and haven't had this problem.

It's possible that a mem fault could cause an os crash, but it's never happened to me. I always got fc's instead. The reboots on another tablet were from turning on the wifi too soon or using a program that needed root before superuser loaded.

This is an easy step to try, beats a system reset.

Hi matt. If you and others think it is HD Widgets, has anyone emailed the developer to ask them to look at the problem?

If you read the devs replies in the reviews on google play and the xda threads, the dev claims it is a google os update issue. It probably is. HD Widgets seems to be triggering the events more than any other app. Disabling location in the app is a temporary solution until google gets their act together. I blame google, not HD Widgets. Man, you guys love this program, I'll have to check it out when this is over! Nevermind, I'll get it now and be another test bed.

Yeah, it seems pretty cool, only crashes so far when trying to back out of the app. Force close not reboot.

Also put on project m live wallpaper, let's see how quick I can drain the battery. Leaving gps and wifi on.

I don't think that we can attribute the reboots to HD widgets. I had no issues while I have it installed. My wife did not have it installed, yet she was experiencing the reboots. Completely opposite findings.  Let's continue to work together on this to gather enough data to be conclusive.

Sounds like a plan. I posted this possible fix after finding it in at least 5 sources in an attempt to forestall a flood of posts on rebooting. I could link if you want. I'm not claiming complete sanity for myself, but maybe they are all hallucinating.

This source sums it up pretty well.

I agree with loociddreemr, if people not using HD Widgets and still getting reboots and people using it are not then it cannot be the culprit. I am not using it but I have not suffered a single reboot since having my 32GB Nexus 7...

It has been reported to be a google lock screen widget issue involving gps and location services. Not just hdw. The developer of hdw says that google did not test non- google widget apps before the last update.

There are probably other reboot causes as well.
Title: Re: New 4.2.1 issue?

3 force close, 2 reboots. Disabling in-app location.(hdw)
Title: Re: New 4.2.1 issue?
Post by: matt on December 05, 2012, 07:49:27 PM
No reboots or fc.
Then hdw updated to fix  4.2 reboots.
Tablet rebooted immediately after update.
Re-enabling location.

No faults.
Hdw may be fixed. Still stress testing.
Suggest disabling location services in all widgets and inputting location manually. Like for weather updates.

No faults. I think HDW is patched for the 4.2 location services bug. Now the dev needs to tell everyone else how he did it!

The 2nd update also caused a reboot. Ironic. Reminds me of win7, restart now or later?
Title: Re: New 4.2.1 issue?
Post by: matt on December 08, 2012, 03:48:01 AM
And end test.
Other than the 2 reboots immediately after updating hdw, no faults.

Test bed = stock unrooted nex7 on jb 4.2.1
All services on except Blue Tooth and nfc, except where noted.
Running Project M in live wallpaper mode, video aggregator TV Portal streaming to BS Player in pop-up mode while loading and exiting apps too numerous to list.

If the developer of HD Widgets is a member/reader of this forum then he/she deserves many thumbs up/kudos for the patch.

I had a reboot immediately after uninstalling HDW. Nothing since.
I'm thinking this reboot bug has to do with location services, and not GPS.

I'm guessing that location services is some kind of reverse ip address look-up database that internet providers contribute to. On a tablet without a gps module, location services would position the device to the wifi router I used. Like in google maps.

The unintentional reboots seemed to be caused by widgets that used location services, not gps. For me anyway.
