Persistent ICS Bug List

I know there are threads for each release but I thought it might be a good idea to list the ones still out there in one place.
These are for the Samsung leaks only, not CM9 or AOKP.
As of FC18:
Exchange contacts/calendar??
That's it?!
As of FC07:
GPS
Cell location (works but eventually craps out. Reboot fixes)
Signal bars
Notification vib+sound
Exchange
Post others I may be forgetting and I will update OP.

That sums it up in a nutshell. The only thing else I can add is better power management and the abilty to use apps like setcpu.

Is it weird I won't permaswitch to ICS until vib+sound is worked out? lmao. That was the killer for me, of all things.

What is wrong with Exchange? I sync to my work exchange server just fine.

I'm not sure if it's just the ROM or ICS but on both AOKP and CM9 I've had it happen that if I'm in a area with very poor signal, it'll go to airplane mode on it's own. The plane doesn't show in the status bar when it happens so I'll have to check it often to make sure it isn't on since the signal bars obviously have their own bug as well.

Exchange is all I need. Could you elaborate on what doesn't work. Also GPS and cell location are important as getting through LA is a constant battle during traffic times.... I drive all around Southern Cal for my job (paid for travel time but if I don't have to sit on a dead freeway, why waste my time).
I can't make the switch until I know these work 100%.

I also do not have any major exchange issues,

Can I get a consensus on Exchange from non-modified stock FC07 users? I'll take it off the list if it is truly fixed on the stock rom.

You can GPS to work by flashing back to GB, get lock, then flash back. But it is still a little wonky and doesn't work out of the box so on the list it goes.

FC07 GPS worked out of the box fine for me and many people for the first time. I have a feeling some of the people without GPS didnt do full reset or are on the list of people with hardware defects. Seems to still not be working for other people that have a clue so its hard to say.
FC07 still does have GPS related issues like it wont stop searching for a lock if it begins and you end up in an area that GPS would never work in the first place. So its still valid that there are GPS issues for sure.

+1, i haven't noticed anything out of the ordinary with exchange

Sound notifications, especially sms stops randomly.
A reboot then fixes it.
Strange

From what I've gathered from a variety of threads, the Exchange issue depends on the version of Exchange and relates to the Exchange function that allows it to remotely manage your device.
Those of us on newer versions of Exchange (I'm on 2010) can't sync calendar or contacts on ANY of the Samsung ICS leaks. I have to replace the email and exchange apks with AOSP to get it to work. Otherwise I'm SOL.
So to be clear, there is DEFINITELY an Exchange problem, even if you're not experiencing it. But it's apparently specific to certain setups, and enough of us on this board have that setup that it's a serious problem.

a MAJOR bug that I want fixed is the head phone out.
When using the head phones or the dock mode heaphone output... i CONSTANTLY get a static and beeping.
I can hear the music, but I get static and beeping.
Tried different wires, different head phones, different docks all with the same results.
No quality audio through the head phone port.

Home WiFi not working on E4GT

I obviously have the Sprint S2, and I continue to have issues staying connected to my home wifi. I have no problems connecting to other wifi networks. It will connect, then after a few minutes, it disconnects, even though it shows I'm still connected in my notification bar. I've searched high and low. It seems many other people are having the same issue, but no one seems to have a fix. Anyone here know of a solution? Thanks in advance.

I'm thinking it might be the router because I've not had problems with any other networks. I just ask because I've noticed that other people have had the same issues with this phone. Here's a screenie of what I'm running. Thanks

So I finally figured out what the issue was. A lot of mobile devices have a hard time connecting to highly secured networks such as wpa2. If you have a wpa, or wpa2 protected router, you can only use numbered passwords. Up to 10 characters. I tried this, and it's the only solution I found. If that still doesn't work, change your wpa2 security to wpa, with a numbered password only.

Try changing the channel on the router, force it to a different frequency B or G only also.

if you have to use numbers and only 10 chars, it sounds like a router config issue. sounds like you have WEP on rather than WPAx

Wifi busted
I actually have the same issue. Wifi worked flawlessly on gb. On ics every time phone goes to sleep it drops, notification says connected. Toggle wifi off and back on works, phone sleep back off. Tried wifi never, only when plugged in. Switched to 2.4 ghz only tried 5 ghz , too. Linksys ea4500 wpa2/aes(setting) brand new. None of the numerous other devices in the house have any issues. Speeds seem awesome.
Tried factory reset nothing works. Even got sprint to get me a new phone, still no solution other than going back to el29. Currently, running fi03 stock rooted. Scared to try latest fi25. Any other suggestions would be great.

still sounds like a router compatibility issue. See if it happens on a different wifi.

The only way i can successfully stay connected is if there is no security or wep is used. Same router nothing had changed. Again worked flawlessly with EL29 update comes to FF18 and it no longer works. Sprint has said it is a known issue with ics on samsung and htc but no fix. Don't want to give up my security just to use wifi. If i roll back to gb everything works again without changing anything in the router. So i don't believe that is it. Plus, i know all about router settings not a noob. I beleive it to be something in the phone update.

My wife runs fully stock newest release and its fine. Try a different router. routers can have compatibility issues with devices. Also you say "its a known issue" but can you give a source?
I'm not saying its router settings. I'm saying it can be a compatibility issue between router and phone chipset.

I was having this issue on fi03 and fi25. Tried different modems, kernels, routers with no improvement. Downloaded WiFi keep alive from the market and use workaround #1 and it hasn't been an issue. Doesn't answer the question but it does solve the problem. Hope it helps. Good luck

I guess i should've mentioned there are 2 of the same phone in the house. Wifi works fine on the other device. Source? As in sprint tech support told me over the phone it was a known issue with samsung and htc devices, not all are affected. This is why sprint decided to replace my old non working phone for the new one.
Not sure why of it were truly a setting inside the router why would one work but not the other? Seems highly improbable to me, just saying. I do appreciate the feedback though.

So two of the same phones. One connects and one doesn't. Interesting. About the tech, seems a pretty wide declaration of an issue. samsung and htc phones. lol. There are a ton of those and its a 'known issue'. If it were a known issue, they would have it tied to a specific phone and wouldn't say 'well err um some phones work and some dont'. lol. Anyway, I don't usually trust those techs.
Back to the issue. If one works and one doesn't... Then it sounds software or still compatibility type issue.
Have you tried these things? If it were me, this what i'd try....
1) I'd reflash your phone's ROM fresh and try again. Full wipe. It's possible the update boinked your wpa_supplicant settings.
2) DHCP: stick a static IP on your android and see what happens. (dont confuse this with a static dhcp lease) DHCP does some interesting things on android phones as far as wakelocks and such.
3) In the router, turn off all the bell and whistle crap... Some of these routers have things like 'afterburner' and things like that. It can cause issues at times. Keep track of what you turn off and obviously if it don't work, turn it back on again.
EDIT:
This is interesting as well. Your not the only one.
http://forum.xda-developers.com/showthread.php?t=1847889&page=4
Try the things I posted but ultimately, you may need to just flash a different ROM version... Doesn't mean you need to go all the way back to EL26. At least you know its not only you...

So I initially called Centurylink, and they told me to change security settings. I did this, and it worked for a short period, but then dropped again. I couldn't figure out why this kept happening, and it had become quite frustrating. Then I realized that I had created a new network with a personalized name and password. My laptops connect fine to that network, but my phone won't, so I connected to the initial network created by Centurylink, and have had no issues. So I can suggest trying that as well. Hope that helps

Same issue for me too, since moving from gb. Running S710.10 S.FI27

different rom? mine never ever disconnects running cm10.

Set up both home networks using WPA/WPA2-PSK and no issues. Did have issues at work with WEP so perhaps that's the offending solution? If so try TKIP instead.

Gone in FI25/FI27 - looks like it won't be re-appearing until JB, at least if FI10 was accurate in this respect.

Wifi Issues in 4.2.1

Not sure if it's just me, but on my Nexus I am connected to wifi while at work and at home. When the screen turns off so does my data about 10% of the time. When I turn the screen back on it will show just the cell bars (full signal) with no data icon (H, 3G, E, etc.) and no wifi symbol. After unlock it will try and re-connect and eventually does. In my wifi settings I have keep wifi on during sleep set to "always", and wifi optimization turned off (<-- not sure what this does).
Anybody else with this issue?

Yeah I get this issue too after the update...even with WiFi sleep set to never....and the new option for WiFi performance switched off! Any help devs?
Sent from my Galaxy Nexus using xda app-developers app

Same for me, but try this : (this is what i do)
go to wifi settings and turn it on, wait for it to connect then turn it off, then on again.
this solves it for me but i have to do this every time i want to connect to a wifi network

This always happens to me too I just thought it was because of the new wifi-optimization so I never thought twice about it...

Same problem here, any fix/solution for it?

judging from responses I guess many have tried/failed to find resolution.
in my case, and I THINK it is since 4.2.1 - can't prove it - the reception is just abysmal on my home ap [repeated, one single ap id/login]. nexus 7 beyond about 4 meters from any of the devices gets a flaky connection, will drop, reconnect in the background repeatedly. if I use wifi analyzer on the nexus it shows a "fair" signal at that spot - use it on a better device and of course it shows a better [green] signal .. surprise surprise.
my geriatric Optimus P509, the galaxy s4g, ipad mini, and venerable thinkpad x120e get good signal on the very spot.
I've tried off/on wifi, cache clearing - no sacrificial animals however...
any clues out there?
oh, and as some few others have noted, I get a different signal indication in portrait mode vs. landscape, no matter how my fingers are arranged. and just the act of flipping it into the horizontal will cause a disconnect/reconnect.

same problem, don't know how to solve. I guess (just guess) it may be relavent to power management, because it often happens at night, when I left the phone untouched for several hours. I think during this long period of time the phone goes into some kind of "power saving mode", which affects the wifi and data connection.

I'm in the same boat, I've got the same problem with mi wifi. Everything works great, except when I turn off the screen and my wifi begins to act crazy turning on/off all by itself.
I've tried latest aokp latest cm 10.1, different kernels but nothing. I'm thinking to go back to 4.1.1 to see will the issue still be there.

Report back if it works good in 4.1.1.

After flashing back to CM 10.0, everything is working perfect again, no wifi issues at all.
So it's a 4.2.1 issue... Maybe a modem + 4.2.1 issue? Or is this issue specific only for a few devices?
I'm using LF1 modem.

After OTA 4.1.2 Update, having wifi issues/problem

I was using MrRobinson's stock rooted rom. When OTA 4.1.2 came out, I unrooted, installed patch, ran CF-Autoroot then I'm back to rooted again. However I did notice, every now and then, my wifi stays connected but connection dies. Internet connection is simply dead. So I don't get any email notifications if ever I get new emails. To fix this I have to turn wifi off/on and internet is ok again. I thought maybe I did something wrong so I wipe cache/factory reset, odin back to full stock non-rooted, installed OTA then use Exynos Abuse/Exploit to root. I am still experiencing the same issue. Att Smart Wifi is disabled. Wifi is always on under sleep policy. I have scorched the net and I can't find any solutions Any help would be much appreciated.

Mine is on the oem update no root even, and my wifi sucks now. The signal and connection will be good but it can't up or download anything. Wifi speed and cellular data speeds are all sub 1mbps also. ATT wifi is disabled also.
The only thing that helps me is to just pair to another wifi source, and go back if needed. Annoying! I'd love to find some solution also, I don't mind rooting if need be for it also.

You can still do warranty to get a new one just call att and tell them your situation with it. This would be my best recommendation to you. Or just root and keep running roms. This is one phone that I havent had the urge to customize with a rom or anything yet

Perhaps it's a minor bug somewhere and the custom ROMs happen to pull that wireless code piece from something other than official 4.1.2 where the bug (if it is one) is located.

True, but 4.1.1 didn't have this issue. They must have changed something.

I don't know if it is related to the issue in this thread, but I had a problem with the phone since I got it of the WIFI constantly connecting, then disconnecting, then connecting again. I solved it by changing the security model of the router from WPA/WPA2 to WEP128.

Yeah saw that thread somewhere but this is a whole different issue. Wifi stays connected but no connection to the internet. You get connection timeout.

Yeah mine just quits. A note 1, a note 10.1, 2 ipads, 2 iphone 4's, and xperia ion and three separate computers have had zero issues on any of the wifi networks here. In fact, if I leave it be, it will not work on the phone, and it now seems to block all the rest from access! If I turn the wifi off on this, perfect immediately afterward. Strange.

did you try just simply reset your router?

I had all the problems in this thread after 4.1.2 A factory reset fixed it.

I'm using the international ROM (custom but fairly stock) and started experiencing the same issue when I switched ROMs.
Toggling the wifi always fixes the problem, but it's not a permanent solution. The problem seems to happen when the device goes into sleep mode for me.

Didn't think I had WiFi issues until today.

So myself and the wife are at Applebee's. She gets on WiFi no issues and I can't. See below screen shots. I even rebooted my device to no avail. Mine was always unstable and would drop. Hers was solid see.pics below. Mines the N900T and hers is the N900A. Both using Att sim cards.
I'm thinking Samsung used different chip sets sources for their wifi.

Doubtful that they used different chipsets. So you are both on stock roms, or have you been flashing stuff on yours?

Have you already factory reset your phone? A lot of people have had minor issues and flashing stock firmware or factory reset has helped some issues.

Sitting by pool, about 60ft and 3 walls from the access point. SSID name is "Disconnected" (really messes with the neighbors). Access point is well sitted, up high in my home office fairly new with current firmware..
You can see the 5Ghz version of the AP in the list as well.

You might have to go back to factory rom, or turn your wifi off and disable always scanning. It may be trying to find a better network.

My range is very respectable. But unfortunately today I discovered this issue. It would very slowly connect then disconnect even quicker. Two stock phones on same WiFi in my neighborhood grill lol.

Unfortunately, i think its just the hardware. Your phone might have two antennas and if you find your correct kernel, you could change it to run off the best antenna possible. might take some testing and such. if all else fails go to your service provider for a evaluation

Thanks for taking the time to look into this. I never really had WiFi issues before until today in the restaurant. If it wasn't for my wife having the same phone I would have addsumed it was the stores router.

Your quite welcome, always glad to help. My old Galaxy would malfunction the same way sometimes. Sometimes between my router and the neighbors and Other times on random hotspots. Sometimes you may have to go in the browser and accept a terms of use. If you figure out the problem, send me a pm.
Cheers - Colgan

Yes, correct. Once after connecfting to the Wifi Router I need to launch the stock Samsung browser to accept their terms and conditions, this process in itself takes about 5 mins or hangs proir to terms and conditions screen it boots me off the WiFi and says its unstable or too slow per my original post.

Its just that theres too many people on the network, Thats the only issue. It mainly does this on public networks. So it is not a phone problem its a client network problem :thumbup:

I had this briefly on my home WiFi. Wasnt a client network as I allow 10 objects to be on mine. Its water under the bridge but that is a possibility on a public network.

I had this problem in spades.
It has nothing to do with a public hotspot or router.
I'm not entirely sure it's not on some type of pattern yet, like 7 or 8 days.
I'll bet you that if you had powered off your phone for a few minutes and turned it back on, the problem would have been gone.
I am pretty sure this is something going on with the Radios in these phones.
Everytime mine gets flaky it usually resolves with a power down for a few minutes.
The other problem I've seen is that if I shut down wifi a number of times in a row because I want to use Mobile data, it will then start not staying connected when I want to use it.
I have to power off and power on and re enter the WPA2 password.
After seeing another thread with some other strange issues, I'm convinced there is a HW or SW issue related to the wifi radio.
I have seen the message exactly like you have here on a AP at my house that only has 2 clients on it and performs flawlessly.
It wouldn't connect to attwifi at Sam's yesterday for some reason.
This is one of the reasons I won't ROM it yet either. I'm still not convinced that it might not go home to the mothership at some point.
