So I am not the only one this is happening to.
I have the Telus variant of this phone, stock. Talking to their tech support, they would have you believe that this is only happening to you.
When phone is first turned on, bluetooth works fine for trip into work. I turn bluetooth off when I get to work and leave the phone on for the day.
I turn bluetooth back on when leaving work and it is intermittent weather it will connect or not. If you go to the bluetooth screen and tap to turn on bluetooth, it shows "turning on..." but does not turn on, no check mark in the check box. After about 30 seconds it stops trying.
At other times it shows it is on and connected to my speaker-phone. When I get an incoming call, the phone will ring instead of the speaker-phone. If you try to answer using the phone you get nothing because it is connected to the speaker-phone but not transmitting.
I am on my 3rd bluetooth speaker-phone, 2 blueant S4's and a Jabra freeway. I have had connection issues with all devices.
I have sent my phone into Telus repair twice and they did a factory flash the first time. The second time I was given a refurbished S2X. The problem is still there even on the replacement device.
The connection issues don't seem to have any consistency factors, ie after running a certain app and it is hard to recreate for Telus staff at store when trying to show the problem.
Lately if you try multiple times to turn on bluetooth when the connection issue is happening, the phone will lock up and turn itself off. At this point I have to remove and re-install the battery or the phone won't turn on.
We have a hands free driving law in Ontario so I need bluetooth to work.
I hope Telus and Samsung can get their heads together to sort this out. I am really starting to get frustrated with this problem.

[Q] Xperia Play Wi-Fi Only

I live in Canada.
I only want an Xperia Play as a wi-fi only device, to play emulators, listen to music, take pictures, just something I can have with me on trips and use as a mini-android tablet. I do not have a cell phone, I don't plan on using it as a cell phone, I don't really like cell phones. I never plan on putting a sim card in this thing ever or making a single phone call on it.
I ordered a Verizon Xperia Play from eBay because it was super cheap compared to everyone else.
My question is this:
Will I have to do anything to this device to use it as I have stated above? Or will I just be able to use it right away.
Thanks very much for the help.

If thats the way you want it, you'll have to disable mobile data, and background data. This will keep it from trying to connect to anything.
The cell radio will stay on for the emergency call feature. But this can also be completely disabled if you turn on Airplane mode. Which disables everything. you can turn this off when you want to connect to Wifi.

Thanks very much, that was very helpful and concise. Cheers!

Actually, you can turn airplane mode on, and then turn WiFi on. You don't need to go out of Airplane to do that....

This is how I use my Xperia Play. I don't have a sim card in it. I leave it in "Airplane mode," and then turn on WiFi when I need it. I leave "Background data" enabled so I can access the Android Market when WiFi is up. Also FPse needs to check in every now and then, or else it goes into limited mode. I think Background data needs to be enabled for this to happen. Airplane mode keeps battery usage low so I can keep playing.

Really? Didn't know that, thought airplane mode stopped thing from being enabled.

Yes you can turn on WiFi while in Airplane mode. It keeps the cell radio, GPS, etc off.

Ok then guess I'll recap for the OP:
Turn on Airplane mode
Thats is all. Aparently you can keep background data enabled, it just won't do anything until you turn on Wifi, which works when airplane mode is turned on.
Problem solved.

Thanks, at least I know I don't have to do major modifications. I had visions of a nag screen preventing me from using the device if there was no sim card in it.

Well technically theres no nag screen, but you will have an error in the status bar saying that there no sim card.

Yeah, that's not a big deal.

r800x doesn't require a sim card period lmao so you'll never get that message

Well that's good to know too.

Fine he'll get an error saying no network connection....picky picky.....

Actually I have a CDMA R800x that I use this way and I don't get that error. Then again I am rooted running Turbo Kernel with P.A.C. Man rom.
Maybe that's why?
Before I unlocked my bootloader though, I don't remember ever getting an error message. I do remember everytime I rebooted there was a nag screen that said "your phone is not activated would you like to activate it?" but the choices were activat or skip.

PLEASE HELP: Data comes ON automatically

Guys, need some help here.
I have WiFi at home, and when I'm home, I'm ALWAYS on WiFi. My mobile data is turned OFF.
Now, each time the phone is locked and when I unlock, the mobile data ALSO AUTOMATICALLY turns ON!
I then have to turn it off, and then it remains OFF. But then again, the same thing happens when the device is unlocked.
I tried talking to HTC over the phone, and they told me to do a restart, which I did, but no luck. I really don't want to do a factory default setting. I want to keep that as my last option.
Any idea what seems to be the issue here? It seems to me that it has something to do with the screen ON and OFF time.
PLEASE HELP!

Go To Settings => More => Usage. Turn OFF the Mobile Network (first) option.
Think this should do.
Cheers

I don't know what You mean by data on, do you have working mobile data and wi-fi simultaneously?
You may want to check this: Settings->Wi-Fi->Advanced-> Keep Wi-Fi active when sleep and set it to active.

@veerm, p3v4x, thanks. I figured out the problem. I had installed this app called, Battery Defender, and that was what was causing this to happen. Uninstalled it, and am happy again

question about smart covers

I just got my MoKo case for this. The smart cover is great and turns the screen off and on without having to mess with the power button all the time. But when the cover is closed for any long period of time, the screen does not turn on when the cover is opened. Why is that?

This has come up in a few threads. For me, it seems to be correlated with having no wifi connection. I've never seen the delay when wifi is operational, only when I've either turned off wifi or am no longer in range of the wifi I was connected to. At home, where I always leave wifi on, I can have it off overnight and it still comes on instantly when I open the case the next day.

If you set WiFi to turn off when the tablet is a sleep it will not turn back on after 15-30 minutes. I have mine set to WiFi always on and it works fine. If you want to save a little battery you can turn wifi off manually at night. Shame it doesn't work like the original Nexus 7.

Although I don't have any of my wifi settings set to limit anything and are all set as suggested above, this was still occurring. I just tested this out with WiFi off and wifi settings don't appear to be the factor at all. With the tablet plugged in, I closed the smart cover and opened it about 45 minutes later and the screen came on fine. I unplugged it from the charger and closed the cover again for 45 more minutes and this time the screen did not turn on. Any ideas?
There is one setting that I do not have turned on and it's new to 4.3:
"Scanning always available
Let Google's location services and other apps scan for networks, even when WiFi is off"

When my Nexus is plugged in it never enters deep sleep and the auto on/off works fine.
When I changed the WiFi advanced setting to Keep WiFi awake during sleep to Always auto on/off works fine. If I turn WiFi off or set it to turn off during sleep the auto on/off will not work after 15-20 minutes.
I figure it has something to do with WiFi and/or deep sleep mode.

I had this issue when I was on stock. I believe the device has crashed. At this point, only option I had was to hold the power button until a full reboot.
Ever since switching to the CM10.2 nightlies, have never seen this issue again.
So my recommendation, get off of stock ASAP. :laugh:

That has nothing to do with it here, nothing is crashing. I think it's the smart cover not having the capability to waken the screen when the tablet is in deep sleep. It sounds to me like you traded crashes for something preventing deep sleep.

N7 had been closed for an hour.. I have Wifi off when screen is off... so *IF* that is the cause
- picked up the tablet, opened the cover.. did not turn on
- closed the cover
- opened again, N7 came on
so.. I ask, exactly how did the 1st failed opening wake up the Wifi (but not the tablet) if that is the culprit?
ie. if the determining failure condition is Wifi off rendering the cover unable to wake the tablet, I should be able to open/close/open the cover 100 times in a row without having it come on.

I don't know what the mechanism is, I just know it has never failed to come on instantly when it had a valid wifi connection.
It sometimes (but by no means always) has a big delay when wifi is off.
Those are the only two data points that seem consistent to me. Perhaps it does have to be off a long time and also have no wifi for the cover to not wake it immediately, but I haven't actually noticed if that is the case.

How long did you wait after the failed attempt to try the second attempt? Perhaps its just very very delayed the first time, and by the time you try the second time its "woken up" and ready to respond correctly?

I actually just got this case too well this one (http://amzn.com/B00CKA1IYU). Not sure if its the one you purchased. Mine was sitting in my office closed for about 45 minutes with WiFi off. I went over to open it and the screen turned on. I put it in my backpack later in the day and it sat there for about 30 minutes and I drove home. I got home and took it out of my backpack and set it on my desk unopened and with WiFi still off. I let it sit there for about another 30 minutes. I read this post and thought "I haven't opened the cover since before leaving work". So out of curiosity I opened it and the screen turned on.
So either my Nexus 7 isn't going into sleep with WiFi off or it actually works?
BTW: I like the case for the price! Bought 2 days ago so I paid 12.99 w/ free shipping.

Not the same but it's the same manufacturer so probably the same magnet

You have asked the magic question.
Left the N7 overnight.. got up, opened the case.. and watched... it took 10-15 seconds and then the screen came on, certainly very delayed, but as a consequence of opening the 1st time, as it should.
Just repeated the experiment after an hour.. ~9 seconds from flap open to display on.

I just tried the official CM Rom today, however, the problem still exists.
I have tried different version (21, 23,24/8), still the same....
Very strange...

Problem still exists with Spet 11 build.
A pretty long lagtime for the wifi to reconnect before turning on the screen.
Turning on bluetooth is a workaround.
So smart wake waits for a wireless connection?
Wasn't the case in the old Nexus 7.

For now (until there is a fix), turn on bluetooth and leave that enabled.. very little power drain, and prevents the delay turning back on.

If I have Bluetooth on and leave the cover closed for a long time and when I open the cover again the WiFi will not turn on.
In one instance I can flip the WiFi switch in Settings to on but it will revert to off, in another instance the switch simply refuse to barge.
Rebooting the device fixes it and brings WiFi back (until the next long cover closure).

then you have a different/worse issue from everyone else (ie. the delay turning on after cover is opened).
I'd do a restore from a factory image, and try that for 2 days.. if it still won't turn on, you need to RMA yours.

[Q] Wifi doesn't start at boot

More often than not, when I start up my G pad, the Wifi does not turn on regardless of the way it was set before. Toggling the button on quick settings, or tying to turn it on manually in settings, does nothing; it says "turning on wifi", but it hangs. Rebooting usually fixes it, but sometimes requires more than one try.
Has anyone else experienced this? I'm hoping that it's a software glitch that will get fixed in the next ota update or when I flash my next rom, whichever comes first. If it's a hardware problem, however, I'd better return it before my rma period expires. Any ideas?
Thanks!

In the advanced setting under WiFi do you have the tablet set to keep WiFi on during sleep? I never turn mine off and do not have a problem. Using a v500 not a v510.

Yes, I've experienced it, if by starting up the G Pad you mean from it bring completely shut down, rather than sleeping. Also happens when doing a restart sometimes. As you say, a further restart sorts it out. I very rarely shut the tablet down or restart it though, usually I just let it sleep, so it hasn't really bothered me, except for the first time when I thought for a horrible moment the wireless hardware had died!

Wht if you don't want to use wifi when you boot the tablet? Then you have the wifi radio wasting battery from the start. Can't you install an app tht turns on the wifi at boot?

It took 6 reboots to get wifi working this mornino! Previously it had only taken 1-2 tries. It also had seemed on previous occasions that rebooting while unplugged would be more likely to successfully turn it on, but no luck; it failed multiple times both plugged and unplugged.
Needless to say, I will never turn the damn thing off if I can help it, but I'm not exactly happy about it.
LBJM, I rarely want to start up without having wifi enabled, but I suppose you could use apps like Tasker or Llama to turn it on or off under certain conditions.

The issue isn't simply that Wi-Fi is off when the tablet first boots up, it's that it refuses to switch Wi-Fi on until it's restarted a second time, so don't think this would help.

6 is getting a bit crazy! Thankfully a single restart worked for me on the couple of occasions it happened. I've actually ended up restarting a few times over the past week for other reasons, but haven't seen this issue occur again. I'm going to shut it down completely shortly, so will see what happens then.

I would take that in for a warranty replacement. That sounds like a dodgy network chip on the main board. I just restarted today and had no problem like what you mention.

I turn it off every night and in the almost couple of months that I have had my G Pad I have never had this problem.

Yeah I would RMA your Gpad. You shouldn't have to jump through hoops to turn on wifi.

Oddly, the issue has pretty much stopped - - just as well, since I was past my RMA date! I'm going to chalk this one up to some odd app interference, since it resolved with any rom updates or re-flashing.
Thanks again to everyone for their help!
