[Q] Bluetooth won't enable after OTA 4.2 update

Just done 4.2 update after I was offered it.
However my Bluetooth now will not enable. The notification bar Bluetooth icon highlights but goes back to grey, the on/off slider in settings immediately goes back to off and the power widget BT icon does nothing.
Any ideas? Searched the board but all i could find were people with stuttering issues, not complete failure to activate bluetooth.
Thanks :good:

Might be a stupid question, but have you tried rebooting the phone?
My phone ocassionally locks itself in "shutting off bluetooth" mode, but a reboot has always fixed it.

How embarrassing. Looks like a fair amount of people have the same issue:

Edit: yes, forgot to say, have rebooted and powered off/removed battery - still no change.

Some solution?

From what I've read the solution is to flash the factory image instead, or possibly just factory reset the phone.
But be aware that even with a cleanly flashed phone, BT has major issues in 4.2. Stuttering audio, disconnects, etc. Not everyone seems to be affected by this for whatever reason, but the new BT stack is definitely no hit.

Yeah, having the same exact issues. I'll wait for 4.2.1 before I flash any images.

Don't bother, still broken in 4.2.1

i know this thread hasnt been updated in a while but for anyone finding this thread through various searches, the fix to try if you are rooted is linked below. It appeared to be a simple permissions issue

[Q] A few noob questions (or bugs?) with CM 10.1

I've been a longtime iPhone user, and got my feet wet a few months back with my first Android device, a Samsung Galaxy S3. I immediately rooted it, and tried CM 10.1, but I was in over my head, and I hadn't even used my phone enough to know what I wanted to do with it, so I went back to stock.
However, I've run into a few issues with Samsung's stock 4.1.1 ROM, and there doesn't appear to be any definitive answer to if and when they'll update to 4.1.2 or 4.2.x. So I decided to revisit Cyanogenmod.
I installed CM 10.1 (cm-10.1-20130304-EXPERIMENTAL-d2att-M2) last night, and I'm making my way around the system, learning a few things here and there, but I've run across two possible issues. I don't know if it's a bug, or if I'm just doing something wrong:
1. I can't seem to add the camera to the lockscreen as a slider shortcut. In the settings, it gets added just fine, I can see it there, and it saves. But when I go to actually use the slider shortcuts on the lockscreen, the camera isn't there. It doesn't matter which position it's in, either. There's just a blank spot where the camera shortcut should be.
2. The battery light -- I can change the color easily enough, but the option for pulse length is greyed out, and the option for pulse speed doesn't seem to save. When I tap "Test", it works, but once I tap "ok", it goes back to "custom", which seems to be a steady color, no blinking. Again, is this a bug, or just something that I'm doing wrong?
Thanks

The lock screen shortcuts I think you have to save before you exit that screen. There will be a floppy disk looking thing you need to press before backing out. I dunno about the notification pulse, it should be set once you've put in the value you want. Unless the ROM just doesn't actually have that functionality.

Ok, I just double-checked to make sure that I did, in fact, tap that save button. I did, but it's still not showing up. I tried blanking it out, saving it, and re-adding the camera and saving it, but it still won't show up.
One other "issue" that I just remembered, too... is there any way to get a counter of unread emails on the email icon, like the standard ROM does?

D'oh. You don't need to set the camera app to your luck screen shortcuts because all you have to do is swipe to the left from the right most border of your lock screen and it goes to the camera app.
I don't think there's an unread counter function in cm, but you can try googling it. I know nova launcher has that, but I've never seen anything like that for trebuchet.

Oh, I see that now.
Anyway, it seems to work after I reloaded CM 10.1. Originally, I was using TitaniumBackup to restore all system and app data from my stock Samsung 4.1.1 ROM, which I believe was causing problems (email was crashing constantly, for example). Once I restored only the non-system apps/data, everything seems to work as advertised (except for the counter badges, which seems to be limitation of Trebuchet).
Now that that's solved, I have another question....
When I go to make a photo a wallpaper image, I get a weird "plus" shaped resizer, which prevents me from using the whole image as a wallpaper. See the attached image. Is there any way to discard the side pieces, and just resize the wallpaper for a single screen?

Google Nav crashing with flashing white/black screen

got an issue with the google nav app crashing on me.
a little background first though.
had this issue on the std rom, and tried flashing the current ARHD 31.3 rom in the hope of fixing it, it hasnt!
from a fresh boot, i can go into the google maps app, choose a location and then use the nav app go to there, no issues at all.
next time, i open maps, no issues at all, choose my location, and as soon as i hit start navigation, the nav screen opens, showing the next turn to make at the top, the voice is telling me where to go, but the main map screen, is flashing black and white.
it flashes like that for 5 or 10 seconds before crashing, the only way to restore navigation to a working state is to reboot the phone.
its getting rather annoying now, as i dont use the nav very often, i tend to need it occasionally, and its irritating to have to reboot the phone just to get the nav working.
as far as i am aware, the GPS works fine in everything else, (Maps, strava, gps test) it just seems to be nav thats causing the issue.
i've already tried clearing the cache from settings, apps, clear data, but i still get the same issue
any ideas on what might be causing this
cheers

Had this too on CM, thought it had something to do with the ROM but after reverting to stock exactly the same issue. You're not alone

Any update on this issue? I have exactly same issue on stocked One X with Sense 5.0, Android 4.2.2.

I have exactly the same problem. I'm wondering if it's a Sense or app issue. Either way, I submitted a bug report.

I turned off the hardware overlay in the Developer section, and it seems no problem anymore... Not thoughtfully tested yet, tho...

Still flashing and crashing HTC One X+
Google maps to navigation is still flashing and crashing - even after turning off hardware overlays.
Works 1st time after reboot. If I swipe the app away from recent apps screen, then it starts failing.
3rd time I start it, working again, but I figure it's going to happen again.

Anyone ever get an answer to this? Last post I found was December 2013 and still nothing.

I think I've found a kind of workaround to prevent this problem.
When you search the location you want to reach, and you are faced to the tile with these info:
8 min (3,1 km)
some info about trip
[MAP]
Start navigation
Instead of click on "Start navigation", click on "8 min (3,1 km)", then when the map is open, click on "Departure" and maps should not crash.
I hope the explanation is enough clear, I've translated texts from the italian app so I'm not sure if I've did it in the right way.

Totally works! Thanks!

Cyanogen 10.2.1
I was so annoyed with this...

I have had this problem for the last year using the stock, rooted AT&T Rom for my HTC One X + My wifes phone that is an HTC One X does not seem to do this. I found when I removed the maps update it worked well. When it updated it seemed to work a few times then the flickering and crashing started up again.
I tried the other suggestion above.
Finally I noted that when I clicked on start nav and as soon as it tried to open the map if I hit the power button and waited a second and turned it back on the image was stable. Sometimes I couldn't catch it before it crashed but if I did it would do the trick.
Why doesn't google fix this?

Same here. One X with rooted stock ROM.
When the flickering starts, i turn off the screen and then back on. This works for me in most situations. Still really annoying.

[Q] Lockscreen icons not working, PLEASE help

I have a weird problem, a few days ago I could not turn off the morning alarm because the icons in the lower bar (turn off and snooze) just couldn't be pulled up. I thought I was just too sleepy but I later realized that I can't use the lockscreen shortcuts either. The phone registers the touch but the icons just don't move upward. Also can't decline a call because of this.
Everything was fine the day before this happened, there were no system updates, no settings changed. The phone is running on stock rom, Android 4.2.2, Sense 5.0. No matter what settings I change I can't get it to work again, tried searching google and xda and found nothing similar. If I try to use the lockscreen shortcuts multiple times and then go to the app drawer and just scroll up and down sometimes a random app opens, most often messaging or mail, like it registers the lockscreen command only then. This is so annoying, does anyone know what I can try to eliminate this problem? I wouldn't like to try flashing a custom rom because I don't have any experience and am otherwise satisfied with stock system. Please excuse me if my questions are in any way stupid, I'm just a noob

I still can't find a fix for this, is there really nobody else with this problem?

Now I decided to hard reset the phone to fix this...yeah right, the shortcuts still don't work!

Notification bar pull down stutter after unlocking phone

I searched forum for similiar issues but could not found anything(though there are some reddit topics).
When I wake the phone with power button or fingerprint sensor, and try to pull down notification bar, there is a stutter/lag lasts 1-2 seconds. Lets say you pull up for app drawer there is nothing but pull down and there it is.
Also wallpaper seems to affect it a little bit but it might be a placebo effect as it still stutters(light the way wallpaper seems to solve it a little bit.).
It started after Android 10 update and I even tried to clean flashing whole rom but result is same and I do not have any UI altering apps.
It seems like a slow wake up issue and may be playing with sleep frequencies might solve it but I did not root so it is not a option for me.
Is anyone else facing this ? Vanilla or custom roms/kernels ?

Yep, I have the same issue. It's pretty annoying, but I did get it to stop, for me at least it seems the new gesture navigation is causing this because I can't get it to stutter while using the 2 or 3 button navigation methods. I've had this happening since I updated to Android 10 (stable release, not beta) but after a while it just fixed itself, unfortunately my phone ran out of battery yesterday and today after I booted it up it came back to haunt me :/

Alright I got it to stop, disabling both "New notification" and "Double-tap to check phone" did it for me. Hopefully this helps.

I have exactly the same issue on my Pixel 2XL, manage to fix it by disabling Google Feed on the left of the main home screen. Try it let me know if it works.
Update 1: disabling google feed doesn't work. I try to switch back to 3 button navigation and the issue gone.

I do not know how but now it is smooth everytime I try to wake phone and double tap+alwayson display is enabled. Also I tried all wallpapers and it works without any stutter.
Probably monthly updates fixed it, idk.
