What does the wifi icon look like when you're not able to connect?
I've had intermittent issues where my tab will drop off my home wifi. The icon in the corner is (best I can describe it) entirely gray with no 'pie pieces'. If it happens again, maybe I can screenshot it. This usually occurred after waking up the tablet (e.g. never while using the tab).
The weird thing is that, during this time, I'm able to use wifi analyzer and see the signal strength and it looks normal. If I disable and re-enable wifi, it sometimes comes back for a short time, other times it goes back to no signal immediately. If I go into the wifi settings and select my home wifi then select connect, I'll usually see a brief error pop up regarding 'could not connect'. Again, maybe I can grab a screenshot the next time it happens. I've had this issue with the BAKED Blackbeans and with CM10 ROMs, and rebooting has usually fixed the issue.
Long story short, I no longer use any wifi controls when the tab is asleep. The BAKED ROM has some controls in its settings, and I was also using the GO TaskManager which also has controls for wifi in sleep mode. Since then, the issue hasn't reoccurred.
Good luck.

[Q] - Random Wifi Shut-Offs And Problem Turning Back On

One day my skyrocket started acting up. I have the AT&T version. what happens is The wifi could be working perfectly fine then when i let it sleep and then wake it the wifi is on and sometimes turns right back on and connects and other times it won't turn on, even when I try to manually. I've tried going back to pure stock, ICS Stock, and tried custom roms and it's all the same. Sometimes on first boot the wifi won't even turn on. Then sometimes when I'm out of wifi Range I turn it off and when I come back and try to switch it on it says "Wifi turning on.." then the toggle goes back to off but it still says that. Sometimes when the phone is in use, screen on, I could be browsing the web or on facebook and it shuts off and won't come back on. This has nothing to do with the Power Saving mode, I never touched that setting and I checked and it's set to "Always." So what could it be? It gets extremely frustrating. someone please help me :l
I searched the forums before I posted, I know this may fall into the development category but I couldn't post there..

when you say pure stock, do you mean you odin'ed back to stock? i'm no expert but if you've had the same issues on pure stock rom, custom roms it sounds as though it may be a hardware issue.

Well yes odin'd back, & also used kies through download/recovery mode. well the custom roms it does it on are all stock based... well I had installed MIUI but idk If it had done it on there. this issue is very frustrating..

i realized last night that the bluetooth does it too, so if it's a hardware problem does that mean the motherboard could be bad, not the actual components?

[Q] Black screen

Hi,
I am using the FatToad custom rom. Whenever I turn on my phone via power button the screen stays black. It doesn't look like the backlight is on. However, the menu button and back button light up. I tried using the volume rockers and home button to power on the screen but it's the same.
The screen does turn on after a couple tries. I have to press power button on (lights turn on), turn off, then back on. The number of tries varies. If I turn it off and back on immediately- then it comes back right away. Whenever I am done with a call, the screen stays off and I have to press the power button to get the screen back. I tried setting the phone to turn the screen on when plugging in charger cable but screen doesn't turn on right away. The auto-brightness seems to be working properly.
I didn't have this issue running the stock relay 4g rom. I have also tried the CarbonMod rom and OmniToad roms to see if it helped but would rather not have to go back to stock unless I need to.
I can live it with it but if anyone has a resolution it would be super awesome. Hopefully it's something simple that I messed up and not the phone itself!
Thanks,
-Alan

are you having this issue on all above mentioned roms....i have seen this issue before on other devices and is a deep sleep issue...i know the only rom you may be able to fix this on is my CarbonRom and done so by changing min frequency up a notch...if that doesnt work go down a notch....all other roms besides carbon have this feature force locked as far as i know so you cant do it on those roms

I've got "FatToad" (nice rom, bad name) and the Trickster Mod app provides plenty of tuning options. Since the trouble manifests itself when the screen is off, I would look at mpdecision before I went raising the min frequency. Then again, I don't have many issues with getting my device to wake...
Anyhow, the app has options to tweak.

if its at 192mhz go to 384mhz....if at 384mhz try 192mhz...if either dont work bump it up to the next highest mhz

I don't think changing the min cpu helped. Went up from 384 to 486. Then tried 594.

did you go to the lowest...also whats your method of flashing.....dirty flash? clean wipe?

The lowest option I had was 384mhz.
Flashing via CWM recovery: wiping data/system/cache/dalvik. Then CarbonRom and gapps. So clean wipe I think is what you are referring.

Sent you a zip to try via pm. Just let me know if it works.

Does this issue manifest itself when you have the phone plugged in? Can you get a logcat of the issue? Throwing things at the wall and seeing what sticks may not be the best resolution here. There are ways of finding out the underlying cause.
mpdecision is not the cause here (That only affects the secondary core) nor is min frequency (You can override it in the HypnoToad images too, just set another governor (like say 'conservative). In FatToad it may look like it resets because Cyanogenmod doesn't display the second core in the performance settings, but changing it is sufficient for testing. The official CM 11 builds do not have the touch boost (which only affects things after the phone is awake, and merely sets the secondary core's frequency up to 1184 Mhz when you are touching the screen, but the affect on the percieved performance of the phone due to this is immense)
Deep sleep is likely closer to the main cause because that affects both cores, and if the system isn't receiving the proper signals to wake back up, this can happen. Throughout development on apexqtmo, we've run into similar problems, and it's always helped by getting proper documentation from those who are experiencing the issues.
TL;DR: Trying random things likely won't solve this issue. Getting all the information you can will help.

Thanks again for all the help. I don't usually ask for any but I could not find much on my issue (or maybe I wasn't searching correctly).
I think I did the logcat correctly. See attached.
The thing that popped was:
D/SurfaceControl( 791): Excessive delay in unblankDisplay() while turning screen on: 269ms

When I would hit the power button and screen would not turn on, this would be there. I'm not really good with understanding this stuff. Hopefully this leads us in right direction though!
Edit: sorry forgot to answer your first question Magamo. This issue happens no matter if it's plugged in or not.
Edit 2: I watched the logcat from adb for awhile and I guess the above happens no matter what. I don't see any differences between if the screen turns on or not.

It looks like you have a hardware rev we're not supporting in our current kernel (which is why it works on stock). PM me if you want to mail your phone to me for analysis

This happened to a new device i purchased. After lbcoder and nard trailed through my logs, I was prescribed to resell the device. Your symptoms sounds identical to what I was experiencing. JB stock kernal works. But custom roms which since delved into the new edited kernel doesnt work on such devices. Since re-sold the device. Be interested to know if yours gets fixed where mine didn't. Good luck

Hi guys. I have a strange issue, that might be related to what's described in this thread.
Almost always when I open or close the keyboard, the screen goes blank for few seconds. One thing (that I think) helps is to press power button several times until the lockscreen comes up.
I am currently running LiquidSmooth 4.4.3, tried it with 4.4.4 and also some old backup 4.4.2 and the phones does it always. The critical position when it goes blank is just a millimiter when opening the keyboard from closed position.
Does any of you have the same experience? Can you please help me to determine either it's a ROM issue (deep sleep etc) or hardware issue?
I tried it also with the logos, boot animations and the screen goes blank too. So I fear it's hardware related - maybe a flex cable contact, but it would not come back so easily after few seconds. Another clue is that the keyboard lights and back+home stay on, but the screen goes blank.
I wish it's something that can be fixed by flashing or setting something as I waited few weeks to deliver my relay to Europe... Thanks for any help in advance!

if its doing it an more than one rom it may be hardware...especially if its doing it at startup logo and bootani...does it do it on cm11 as well as omni?

Thanks for the reply. Yes the bootanimation and initial logo is telling enough about the cause of it. I must admit it's a hw problem. I tried to open/close the keyboard quicky instead of moving it slowly, but it occurs too. I'll try completely different rom with different kernel as the last chance
to hope for a sw issue.

I tried Omnirom with same result, but now I did a clean flash of the latest liquid and my impression is that this happens a lot fewer times than before. Maybe I just got the right velocity and force needed to open it gently I also installed just a few critical apps. Before I messed with Ultimate screen rotate etc.
But it now happens more when closing the keyboard. However, I'll rather buy new one, just ot have a backup of this great phone just in case.

Is this "the part" I need?
Do you have any experiences with this shop? It seems to me too much $40+shipping for that cable. Probably I'll just order another one from ebay, preferably new one and leave the current one for spare parts in the future.

Fixed today! You can see the state of the flex cable on the last picture in this post:

[Q] WiFi woes

Hi folks,
There are two issues with WiFi on my Nexus 5. The first, which was happening before I upgraded to Lollipop, is that my phone no longer remembers WiFi passwords and I have to re-insert them every time. I've searched around for this and been told that it's because Android only remembers a certain number of passwords so I've tried forgetting quite a few old WiFi access points but to no avail. Any ideas on this issue?
The second issue has only started occurring since I upgraded to Lollipop and is driving me nuts. Basically I can only very rarely access the WiFi menu in settings now, making it near impossible to connect to new access points. Pulling down the notification shade and tapping the wifi icon just seems to turn it on and off rather than taking me to the WiFi area in settings - is that right? And then if I go into settings and tap on WiFi the screen goes blank and I get a force close message. Very occasionally or after re-starting settings a few times it will work.
Any thoughts on either issue would be much appreciated. I've read the thread on WiFi not turning on but don't think that's the issue and as I say the latter issue has only occurred since the Lollipop upgrade.
Thanks
Alex

With the quick settings, you have to tap the network name to go into the wifi options. The wifi pie slice thing turns it on the off.
Sounds like you could use a factory reset to fix your other problems.

I haven't ever encountered #1, so I can't help with that. However, with #2- touching the icon will turn wifi (or bluetooth, etc) on and off. If you touch below the line (where it says wifi, bluetooth, etc) it will open the settings menu. It matters where you tap.

Thanks for the replies chaps - I hadn't realised that tapping on different bits did different things. Regardless of whether I go in through the settings 'cog' or by tapping on the word 'WiFi' under the pulldown shade though the next screen is still blank and I get a force close message. In fact today one of the times I tried it the phone just froze on a white screen and only holding down the power button for ten seconds allowed me to turn it off and use it again. Anyone had any similar issues?

I'm having the same issues as you (both of them), and I'm also looking for the solution to it. For the first one, I'm trying to disable backup and renabling them. Read online that sometimes there's something wrong with the sync. Not sure if it solved the problem but will try.
For the second one, the problem is because it takes a very long time for the phone to search for wifi hotspots. So if you turn on wifi (ie clicking on the big button) and wait for about 2 minutes for it to search, wifi will work find. However, the 2 minutes is a long painful wait.... Im not sure what is the reason for the wait though, my nvidia shield tablet has no such issues.
Anybody has any solutions?

I tried to do a factory reset yesterday. Took me a really long time but failed. So i ended up having to sideload the 5.01 factory firmware, which formated my entire phone.
In any case, it did not work. It still takes me a very long time 'turning wifi on...'
Any other suggestions?

Phone freezes up

Has anyone experienced your U11+ freezing up.
It has happened to me about 3 times.
It generally happens over night while it's charging. I get up one of those mornings and the green light is on, remove the charging cable and I can't wake up the phone. I can't even turn off the phone by pressing and holding the power button to kill the device. The only way is to put it into download mode by simultaneously holding down the vol down key and power key, and then when the menu comes up to select the reboot option to get the phone back to normal.
Has anyone else experienced this or know what could be causing this to happen?
The problem is that I use my phone as my alarm clock, and when it freezes up, my alarm doesn't work.
Any suggestions anyone?

No problem like that until now.
However, noticed sometimes that the my alarm, which is setup for vibration only, only vibrates once and then continues silently alarming until I turn it off.
Happens randomly but still strange. I've to try with another clock app.

That's really odd.
I'm going to turn off the always - on feature and see if I get anymore freezes. I had another one this afternoon.
I'll report back after some time and let you know if there has been no more freezes.

I'm just updating to the latest update 1.23.709.3 and see also how it performs.
I'm a bit concerned about this random freezing that I have experienced since I got this device.
If it persists I may ask for a new one.

I'm still on the October security patch so I'm expecting one for the December period soon I hope.
In regards to your freezes I've not encountered anything like that so far been working flawlessly so far if there is anything I can test let me know

I have the Taiwan version.
If you could try the always-on feature for a couple of days and nights and report back, that would be awesome. However, I selected the option, for always-on to only come on when I moved the phone. (good for night time use especially)
I had my phone in the pocket yesterday afternoon and it froze.
As I stated earlier, I can only restart the phone only by putting it into download mode and reboot from there.

Thanks for letting me know.
I guess I can rule that feature out as a probable cause.
It must be some other app that's causing this issue. But it's a pain to go through the process of finding out which one.

Yeah trial and error isn't fun. I'd probably factory reset though and see if it happens with barely any third party apps installed.

I have the HK model I think and I had the AOD when I first got it, set to motion and nothing has happened to my phone in regards to freezing fingers crossed. I have disabled it for the moment as I noticed a greater battery usage overall, I believe between 9-10% overnight and only 2% when I had it disabled.
Hopefully you find the problem otherwise see if you can get it replaced...

Since not using the always-on feature, I don't have any more freezes. Must be some conflict with the alarms and always-on. Can't see what else could be causing those freeze ups.

My phone surprisingly just froze up yesterday. But at least it's been a long while since not having the always-on feature enabled. With always-on enabled, it seems to have happened every day.
The issue I have most about this, is missing that important call when I haven't realised that the phone is frozen, because sometimes I don't pick up the phone for hours.

I had to do a complete fresh install from scratch and I have no more issues. I believe all my issues came from using HTC's transfer tool when going from u11 to u11+. Importing all the settings features using the Transfer Tool has caused issues. I'll never use this tool again.
All good now.
