SM-T550 - blinking bluetooth after wake-up - Samsung Galaxy Tab A series Questions & Answers

Hello
I've discovered that after wake-up my tablet, bluetooth always blinks (just one blink - ~1 sec), which drains by battery. I know it is firmware problem becouse i've got same problem on xperia z1 - only solution was wipe system data and install new rom, which I would like to use in the last resort.
(btw, its weird that after fixing the phone, within a few weeks I have that problem on tablet, only thing i've done so far was rooting my Tab A 6.0.1 )
Sorry for my bad english, and thanks for any response.

WTF is that!!!!!!!!!!!!!

i have very strange issue with my SPV M5000, try to describe:
last evening i went to sleep with 98% battery of my Uni, morning buzzer was not ringig, i didn't notice that untill i wanted to start my device and see that battery is drain to 8-9% and this stupid high noizzy sound comes from Uni that battery is very low, so, i thought that maybe i have forgotten wifi or something like that, than after comming to work i connected device to computer, everything was allright, syncing without problem, i left uni connected untill green light of full battery appeared, so after that i open screen trying to delete some missed calls and read some SMS and tried to make a call but uni freezed, and from this point i didn't start it normaly, i've flashed almost all of ROM's found here, but sometimes it didn't start either, sometimes it stuck in splash screen, sometimes it freezes after booting system, strange is that ones when it started it signaled that battery is empty again
common WTF is that, i have uni for 1 year and never, never had this strange behaviour
thanx in advance for any solution how to solve this problem
last flashed ROM is Helmi's 3.5 b1.3.1
Radio 1.14.10
PS> sorry for my english, i hope you understood
your basic english is a lot more understandable than others' basic english :¬)

HTC Legend suffering Standby on Death (SOD)

hi all,
i having my 1st Android phone (HTC Legend), but my set suffering Standby on Death (SOD), not sure if the right term. When it on standby, I not able to wake the phone; only way to remove the battery and on the phone again.
However, during it 'freeze' mode, try calling the phone; won't ring but caller doesn't get any engaged tone keep trying connect tone.
Please advise if any1 experience the above or any steps I can do.
** Try searching the web, only found SOD on Win phone.
Cheers.
Edit/Delete Message
The same thing happend to me yesterday, for the first time (I pulled out battery to reset it). I had a few random resets last few days, but I do use my legend for app development testing, so i'm not sure if i somehow provoked the problem.
Offtopic, but just looking at logcat output of a normally running Legend you get impression that there are a lot of unfinished stuff, especially HTC applications (news widget is terrible)
I'm also seeing the same random resets on my Legend. Not sure what when wrong. I have a bunch of apps installed but I don't know if this relates to any of them.
It happened again just now. Restarts on daily basis now
just make a hard reset
Ok. I did a hard rest. And i don't want to install any apps, let it run in vanilla flavor for 2-3 days and see if it happens again.
If it does, that means it must be caused by one of the apps installed before
I had some SOD's, but after a complete clean and reset to original setting, everything disappeared.
Maybe it was a problem coming from installed software...
clean reset, wiped out everything. reset after 15hrs of up time. i'm going to RMA this thing
Hi all - first post here...
I have not long had my first HTC handset - and I really like it, but nearly every day I get this 'SOD'...as described here.
I had to remove the battery to wake it up again only this morning.
I have noticed, that it only seems to do this when it can't recieve the weather data (under the HTC clock)? the handset never seems to hang etc while it has this data?
Have others seen this? Could it be a bug?
Why not bring all SOD threads to one?
As I see all SOD's are same on all devices.
There is bunch of symptoms but if you have sod than you are experiencing some or all of the symptoms.
General help is to hard reset few times than flash shipped ROM then hard reset again few times then flash your favorite custom ROM or leave shipped, and reset again few times. And finaly set network to GSM+AUTO in Phone band configuration. Or try to change SIM with another network operator.
All of this helped some people but there is many who did not solve the SOD with this nor anything else.
I know I am posting in more than one thread same thing and it is not double or triple or X posting it is just help request for people who could finaly understand what is problem and help us all.
Sory, and thanks in advance.
Weather is not problem on my device, I did try turn it off, disable auto update of everything .... no difference.
Even I leave it connected to USB and it have the internet connection all time and I do not have SOD, I have DIM of death screen dims not turn of and if I disconect it and pres power to go to stand by or to turn off screen I can not power on device until i pull battery out few times - 4 - 5 timesto be precise or sometimes even more.
I got a new replacement unit and it works fine since. I guess my old unit was really defective
Sent from my Legend using XDA App
I have had to have my handset replaced now. My SOD contiuned and then the Mic gave up and no-one could hear me in calls - made it unusable as a phone. I also had battrey issues where the phone wouldn't charge and the battery meter read wrong.
All seems fine with this replacement handset.....

Sleep Of Death (SOD) issue even after update

Hi ! I purchased recently my Acer Iconia A500, and so far I'm very impressed with it. The only concern I have is this annoying sleep of death issue. It occurs to me like 3x a day, everyday ! I've tried everything written by the people (setting airplane mode, disabling wifi when screen blackens, update) but with no success.. anyone knows if this is going to be fixed in the 3.1 update or any update by Acer ? Anyone successfully managed to solve this problem ? Thanks !
Just to know.. I really wish that it's a software problem because I live in Brasil and bought it last week in EUA, so I won't be able to change it xP
As I mentioned in another thread, this has never happened to me. Not before or after the update.
The only thing I may do different from anyone else is I leave USB debugging turned on, I have a password login and as you mention I set the wifi profile to turn off when the screen goes off.
If this is happening 3 times or more a day, I'd highly recommend replacing the tablet. Yes, I know that's extremely inconvenient in your case...
But, have you tried a reset to factory defaults? It's worth a shot...
Prior to the 1.141-update my tab had that too, several times a day. I've put a WiFi-toggle widget on my desktop to be able to switch off WiFi before putting the tablet to sleep - that almost completely got riid of the inresponsiveness after sleep.
After the update to 1.141 there is no need anymore to switch off WiFi while sleeping, the update fixed that problem. But introduced a new one: when disconnecting the charger the tablet sometimes stops responding after about 1 minute and needs a reset.

Freezes overnight with my I9505 Galaxy S4

Hi Guys,
i got freezes when i charge it overnight (its connected to the original charger the whole night). I only can do a hard reset to use my device again because the touch-screen doesnt work then. This is very annoying because i use my device with Alarm to get up in the morning.
I already did a few clean installs (Cyanogenod Snapshots and Danvdh's Google Edition), wiped all caches and formated all data and caches aswell. I still got freezes. I get them from waking up my device (mostly in the morning between 5-6 am). All i see is a exclamation mark when i turn on the display. Then its frozen and i cant anything.
I already tried a few Modems and Kernels to test, but still freezes...
I use Modem I9505XXUGNK4 atm.
Any ideas ??? I really Need help with this !!!
Thanks

Have you tried the new 5.0 gpe from danvh? There was an issue with the charging animation and reboots.
yes, i got Dan's 5.0 gpe at the moment 12.17.2014
Dumb question, did you clear /system in between flashes as well?
Yes, i formated System and Cache + i wiped everything too
You should flash the latest stock firmware and see if the issue persists. If yes, try a different charger. If the problem still persists, I think it's a hardware problem. Probably battery or motherboard.
The Problem is only between 5-6 am. The whole day i got no Problems Should be a Problem with my Router maybe ?
i got no resets in my Settings there. maybe my Provider is doing a reset every day between 5-6 am and my device freezes then. i could try airplane mode too to test, right ?
I bought a new charger and battery today (both original). Maybe thats the problem.
i got News guys, i turned off wifi overnight an didnt plugged the charger to my device this night. No freeze !!! Yay !!!
So it only could be, charger, battery or Wifi, right ?
ok, i had a freeze at work a while ago. but i got no wifi or charger there... now i dont know what to do
Does it behave like this?:
You pick up the phone (it is in deepsleep),try to turn the screen on,it goes on,you try to unlock the screen and it just stops reacting to anything and turns the screen off after 20-30seconds?

i had the same problem,the only way to get rid of it is to send it in/get the motherboard replaced.this is faulty hardware,not a software problem
Damn, but i already got know activated. i dont get one for free Its about 1 and a half year old. The problem was solved a few snapshots form cm earlier and its only between 5-6 am. do you think its really a mainboard problem ?

how was your battery-lifetime with that build?
can`t help you with that,hope you have luck and fix it
Same problem
Hy people, i have the same problem, but is not a specific hour when it freez, yesterday i picked up the phone and when i unlocked the screen, it freezed, but i don.t wait 30sec, i just lock/unlock it again and it work fine. The other problem was overheating..
and randomly restarting but i think i fixed it with a factory reset. What i want to tell now is that i installed "Root booster" before all these problemsc ocured. After it played with the kernel, do you all thing it might not restored the original settings? My phone is randomly heating sice i installed that **** on it...(even if i do factory reset)
Ps: i have a stock kernel/gt_505
Or the battery is guilty? It's draing pretty fast, after a day of use i put it to charge
(Solved)

Hy, i haved the same problem, but what i did yesterday solved that. I hope this steps will help you:
1. Enter in Recovery Mode and select wipe data/factory reset
2. Clear cache partition
3. Go in Settings/More/App Manager and search for Touchwiz Home
4. Force stop then Clear data
5. Withouth exit from settings, restart your phone
6. When phone is on, screen will be black and will ask you witch program you wanna use, select Touchwiz home then press "always"
After this steps, i solved the problem for my phone, but another thing i done after that is delete all knox files with Titanium backup.
I hope this steps myght help you.
Thanks guys, but i got a nexus 5 now. Bye Samsung. Thanks anyway for help.

Wi-Fi completely dead?

Hi,
Wi-Fi on my Nexus 10 always worked good. Then some days ago I turned it on and... Wi-Fi seems dead. I mean it stucks on "Wi-Fi activation..." and doesn't go on. Wi-Fi function seems not to be activable, switch button remains grey and disabled. It happens with 5.1.1 stock rom, then I made a complete factory reset and problem still remained, then i've tried with a 12.1 cyanogenmod and... problem still remained. Wi-Fi seems completely dead. Could it be an hardware issue? Is there an app with whom I can make hardware diagnostics? Or any other advice? Bluetooth also doesn't work and with cyanogenmod every 10-15 secs it shows "unfortunately bluetooth sharing stopped" message...
Thanks in advance.
Hello and thank you for using Q/A,
I don't know if there is a App to check hardware, but I think your WLAN and Bluetooth Chip is broken.
The last thing you can try is flashing Stock via Fastboot. Don't forget to erase all partitions before. There are several instructions in Nexus 10 General section.
Kind regards
Trafalgar Square
I have the same problem, but I am sure the chip is not broken because when I flash and reflash, sometimes the Wifi just comes on. but when I attempt a reboot its gone again. Tried FXR wifi fix but it doesnt always work.
I read somewhere that it could be a problem with the Persist partition but still havent managed to fix it
New problem!
Hi!
I've solved my old problem by replacing motherboard with a new one (with 32 GB HD instead of 16 from my old one). WiFi was perfect. I also had to buy a new 3-button set (power & volumes) because old one was deteriorated. All was right.
But from yesterday a new problem comes out. I was trying to flash last CM snapshot release for Nexus 10, but tablet simply powered off.
If I plug it to PC via USB and press power button I can see battery icon fully charged, but tablet don't turn on. If I keep it plugged, sometimes tablet auto turns on in bootloader mode for a few minutes, then screen flickers and tablet turns off. I've tried to flash CM in these minutes but, at first reboot, tablet turns off.
I think it could be a battery problem. Maybe it's gone and cannot be recharged, contrary to what battery icon seems to say.
Now, I've spent 80 euros for a new motherboard and 15 for 3-button change. A new battery will cost about 50 euros. 50 euros is less than buying a new tablet but, considering a new problem can come out in any moment, is it worth? Also, like when I had motherboard problem, I'm not sure battery is the problem. Any advice to solve or about buying or not a new battery? Thanks!
Took my risks and bought a new battery, arrived on yesterday morning. Battery changed and CM13 correctly flashed, now it seems to be ok. Luckily i hit the right problem.
