[Q] Wifi slowing down to a crawl? - Galaxy S Advance I9070 Q&A, Help & Troubleshooting

Does anyone else have issues where their wifi will gradually slow down as the day goes on, eventually to a point where it takes 5 minutes to download a 500kb app?
I've ruled out router issues (every router I try this with, work, home, McDonalds etc!) gives the same issue. So it must be either a phone hardware issue, or a phone software / firmware issue.
Can anyone suggest a tool perhaps to help with debugging this?
I'm on 4.1.2 LQ4 with LightJB1.2 and CoCore E 6.0. I had the same issue on stock JB and had hoped that rooting / custom firmware etc would present the answer.
Clearly it could be an app, but I'm not using anything that other people out there aren't, so I'd expect the same issues to be experienced by others if I was having app specific issues (e.g. facebook, twitter, Spotify, dropbox, Chrome, youtube etc).
Thanks in advance for any help!

Install this app, and see is there any other app that is occupy internet bandwith. It shows how much MB apps downloads.

Yes, I've tried that (or something similar) in the past with no joy - I don't think that it is slowing down because one app is consuming a large amount of data, it feels more like a sort of "memory leak" on the wifi front (don't know if that's possible!).
I can see it clearly in things like speedtest, which most of the time will show 8-10Mbps download speeds over wifi, and then will eventually crawl down to 200kbps type speeds.
Switching the phone to airplane mode and back again does seem to reset the problem, so it is something I can work around - but I'd like to know what the issue really is as it is starting to annoy me!
Cheers!

[Q] App Data Tracker? Spy App?

Hi guys, need your help on this...
I'm using axura rom and i've always had this problem.
Whenever i surf with 3G, the phone always goes into a data hang.
Meaning, after around 20 minutes of surfing, i noticed there's only data going up, but nothing seems to be downloading.
I suspect there's a bad app that's locking my other apps and been 'stealing' information from my phone.
Do you know anything that can be used to weed out apps like these???
have you updated to the new radios? This helped a similar problem I had.

From a Super Baked Evo #0002
I didn't update the radio. I just used Axura 2.5.1 as it is...
Which radio are you using? (your signature says evo... so, i'm not sure if it's compatible with the captivate).
The current radio in Axura works fine for me... it's just sometimes it randomly stops downward traffic and only the upflow is seen...
So, at the moment, i'm not even sure it's the radio problem...
Coz it works again if you wait a few minutes...
So at the moment, i can't verify it as a radio problem, hence i'm searching for an app that can let me track if any app is causing this sudden 'upload only' situation...
3G Watchdog in the market. Unfortunately, only the "pro" option will show you per-app usage (the free one shows overall usage)
Thank you very much... Will check out that app...
Any other apps that can do this too?

[Q] Problem with WiFi

Hi!
I have a really weird problem with my SGS.
When I'm installing ANY firmware (I've tried every single one) except of my original FW "JPB", I can't get my WiFi working.
There are actually 2 types of Wifi behavior on the different ROMs. The first one is when you're connecting to the Wifi and you can actually open Google.com, Android Market, etc, normally. But when it comes to a "heavy" sites such as youtube, wifi connection just freezes and nothing helps before you'll close the browser and reconnect to the access point.
On some other roms you're connecting to Wifi without any errors too, but you can't actually open any site at all. And only on FW "JPB" (which is russian official) there is no such a problem.
Also Samsung Apps doesn't work on other ROMs, I even thought that it can be related somehow... I know that there's no logic here, so I'm really confused.
Oh, and even if I'm installing Voodoo lagfix on my official firmware I'm still getting into this trouble
I really want to hear your opinion, so please don't hesitate to reply.
Thanks in advance,
Jay

[Q] GPS Sporadic after 4.3 update

I always have raved on how great the GPS is on my S4. It will lock onto satellites with 10' accuracy in the house. It was always spot on and never gave me any issues. That was until the 4.3 update. (I am not positive this was the reason - but it is around that time).
I am a runner so I use my phone 3-4 days a week to track my run 3-10 miles each time out. Before it was always perfect. Now it will lock on and track for a various amount of time.. from a few minutes to 15 minutes - but it will eventually just stop working. If I turn on the phone to look, the GPS icon at the top is not there, and the app does not know it lost gps signal. I can touch the screen and then the gps icon reappears, blinks, reconnects and all is good. I turn off the screen and go about my run and it will work for some period of time and then off again.
It "seems" like to me some app is using the gps and then not playing friendly and turning it off for the other apps. I don't know if that is what is happening but it seems that way.
I get the same results no matter if I use Google Maps, Waze, Runkeeper, or GPS Test... so it is not application issue persay.
I restored to factory and installed only what I need to run (Runkeeper and Google Play music) and it worked without a hitch for the entire 6 mile run. Great! Fixed! So I re-installed my apps and now it is doing the same thing again. So that seems to indicate another app not playing nice like I mentioned above. So I uninstalled any apps that I thought might be an issue and it is still there. So I fear it might be one of the ATT bloatware apps that I cannot uninstall.
Before I undertake the very tedious task of restoring to factory, running 6 miles, installing 1 app, running 6 miles, repeat --- until I find the culprit - I was hoping someone might no a quicker solution?
Thanks!

Are you sure it's not staying connected but not displaying the icon? Ie, if the app hasn't realised the connection has dropped, maybe that's because the connection hasn't dropped, just the icon has? In tech terms, to solve a problem you must first find it by isolating the cause, which would be the tedious task you're referring to.
Even then, it is possible it's a hardware or firmware issue, so a factory reset still might not fix it. Have you tried an app like this? It ill set your NTP Server without searching for it so that it connects quicker, maybe (I'm not sure) it will be able to keep it connected to that server.
Do you have CWM? You could flash a different ROM.
I can confirm this problem. It is intermittent. GPS loses the location fix. I had a similar problem with certain Motorola Attic ROMs that had something to do with a conflict with the "Use Wireless Networks" setting. I'm those ROMs, I could turn that setting off, and GPS would work fine. That workaround doesn't work for this ROM. I only mention it to help rule some things out. I thought that it worked fine right after I updated, but I may not have used the GPS much our maybe I just didn't notice. Yesterday, it was barely usable. I remember that epinter, in the Atrix 4g forums, had a tool that reset some GPS settings. I'm see if I can find it and test it. I will report back.
Update: Today, GPS works perfectly fine. Seems to be intermittent.

Still having the issue. Reset my phone to factory again this time taking the extra step to format the SD card to just in case. By the way - I am running stock AT&T 4.3. This time when I reset I did not connect to the WiFi so it would not automatically install / update any apps.
I then added only 2 apps - Runkeeper and Play Music and went for a run. The GPS tracked perfectly for a 5 mile run.
I then installed GPS test and let it run for an hour or so. It never lost connection.
So I updated GMAIL. Repeat GPS Test.
Updated Hangouts. Repeat GPS Test.
And so on.. finally after about the 10th app it failed. The last app I had installed was Facebook.
So uninstalled. Failed again. Uninstalled the previous app to that which I think was My Fitness Pal.
It seemed better - it would go hours before failing... and then only seemed to fail when a phone call came in. So thought I could live with that.
So went to the gym and to test it I used Google Maps to navigate. Terrible! Would not work for more than a mile. I finally gave up.
When I say it is not working - I mean the GPS says it is on. The GPS Test app says the GPS is on. But the icon at top goes away and Google Maps says "GPS Signal Lost." In my Run Keeper app - same thing - icon goes away and no more mileage is recorded. If I turn on the phone, open Runkeeper - it then restarts the GPS and all is good for another few feet or maybe a mile and then it does it again.
I tried turning off the Use Wifi for GPS option and that has not helped. Thanks for the suggestion though - you gave me hope.
I have have been a software developer for 20 years and this just smells like buggy code somewhere and not a hardware issue. Either something to do with the new OS update from ATT (but why is no one else complaining) or some combination of apps I use. Runkeeper. My Pebble. Something. But it is driving me nuts. The GPS really is the main app I use on this phone... so it is making for a really expensive mistake at this point and I hate to admit that since I love Samsung and Android.
I should have updated my status again. The problem is intermittent, but it happens often. Like you, I am fairly certain that the ML2 update brought bugs with it. My GPS always worked perfectly before that. Now, even when it does work, it doesn't work well. The fix is jumpy and slow to update. My guess is that others also have the problem, and they don't use their GPS often enough to notice or care. I bet that Samsung is aware of it, but so many people had problems installing the last update that they will not be so quick to provide an update that doesn't affect many people. I guess a better way to put it is that Samsung probably doesn't want to take a chance that a small update might break more than it fixes.

I also have same GPS issue since 4.3 , same issues note 3 is having actually if I plug my active in while GPS is on it will stop working and when switching data network types it will lose GPS signal

Convinced it is the 4.3 ATT Active update now after repeated and very controlled resetting and testing.
Frustrating and makes my phone fairly useless to me for my main purposes. Today during a 7 mile run - it lost connection at least a half a dozen times. I have to run with the phone in my hand and restart the gps constantly.
Some people said they had success using Odin to flash the MF1 modem bin file. The thread discusses it here: http://forum.xda-developers.com/showthread.php?t=2691264
However, this did not fix my issues with GPS unfortunately, but thought maybe I'd post it in case it helps someone else.
So it appears that it is, as suggested, the radio that causes this issue.
A "workaround" for using the GPS is to put the phone into airplane mode (turning off the Radio and WiFi) fixes the GPS 100% in my testing.
However this is not a real fix for real use of the GPS to navigate since you have no access to data.
It appears these are the circumstances that cause my GPS to drop:
- Cell radio changes towers (which happens a lot in my remote area)
- WiFi changes antennas
- Phone is plugged in or unplugged
- A phone call is received.
So yeah - as long as your don't use your phone as a telephone - you are grand!
The new HTC One is looking mighty nice to me right now. First non Samsung component (phone, laptop, TV, etc) that I have considered in years...

It's weird that even in airplane mode my Active won't get a gps signal. Used a few apps to test as well: GPS Status, FasterGPS, GPS test, and all say no satellites in site.
I was getting GPS issues for quite some time, until I tightened the screws at the back of my case. It was supposed to be a fix for the S3 but it worked fine on my S4 as well.
Hope this helps

I've tried tightening up the screws a bit, which they did, but still no GPS for me. Going to do a backup and another full wipe and restore.
AT&T fixed my phone
I too had the GPS signal lost issue after the 4.3 update on my S4 active on AT&T. I called AT&T yesterday and they advised me they were aware of the issue. Their instruction was to take my phone to Best Buy where they have a "Samsung Solutions / Experience" dept / kiosk. So I did. They flashed my phone to 4.4.2. I am happy to report that all GPS problems are resolved. I drove for over an hour using Google Maps this AM with no problem at all.
GPS is a big deal for me too. I drive in a lot of unfamiliar towns. I'm also a sportsman and spend a lot of time in unfamiliar woods. I rely on my phone to allow me to retrace my steps back if need be. I also use it to set waypoints and mark areas for possible future hunts. The woods look a lot different at night then during the day. So I rely on the phone to help navigate off the beaten trail and get to my tree stand. GPS failures are not an option. Pure and simple. I can get out of the woods with a compass - but I may not find my tree stand in the dark without my phone.
I don't know about rooting this ROM, etc as I don't have need to root my phones. But it did fix the GPS issue and the phone seems a little faster with battery battery life too. YMMV.
Thanks for your post! Did you l lose any data with the update to 4.4.2?
I have the same exact problem with my S4 active, definitely a software issue. For a while I used the airplane mode work-around which was great, until a recent update to Google Maps causes maps to crash when airplane mode is on, so now I'm back to having no navigation. I'm frustrated that AT&T has dragged their feet on getting an update out to the public. They must have zero QA to let a bug this obvious get into the public. I wonder when they'll push 4.4.2 out as a regular update?

No I did not lose any data or apps. I have no complaints. Phone is working great. I'll never accept another update OTA though - I don't care if I have to root to avoid them.
I got the 4.4.2 over the air update, and it fixed my GPS problems. No new problems.

Internet Connection is Enabled(problem)

Hi,
I have an xperia z1 C9603 on android 4.4, recently something happened, I keep getting a message(the time between messages varying from 5 second to approx. 2 mins) in the lower region of the screen saying "Internet Connection is Enabled", I'm constantly connected through wifi at home and via data services otherwise, I'm curious what started to trigger this and feel concerned that it maybe some sort of malware or spyware working in the background which is causing this, also it seems switching off wifi seems to decrease the frequency of the messages. I have not made any change to network settings, my phone is on the stock rom and is not rooted as well. I have scanned it using dr. web anti-virus and kaspersky(which is currently installed) and have not found anything yet.
Any help on this would be highly appreciated.
Thanks! :good:

Question Sound Lag in Games with WiFi turned on

I've got a Question, I have the Mi 11 Ultra China variant with 8 GB RAM, unlocked bootloader and the official EU Stock Rom.
I noticed that in games even if they are low quality games with low graphics, they are some random Sound Lags.
They appear also with headphones so I suggest this is a Software problem.
I also had that problem with locked bootloader and the official China ROM, so does anyone have or noticed this lag too or I'am the only one?
Edit:
I found the Problem, If I play any games with WiFi turned on, the Sound starts lagging after some seconds , but with mobile data, everthing works perfectly.
Any solutions for that? I tried different WiFi connections and it only happens with WiFi turned on.

I dont think so, every app uses mobile data or WiFi, depending on what if have turned on
This seems for me like a Bad connection, but my Phone is the only device atm and I had never such problems like this in the past with my Phones

Okay so it only happens when you play online? Like with other people on a server? If that's the case i would guess you have a bad internet or wifi connection. So the phone wouldn't be the problem.

Even in Games that have no online play, just Serversided, I got those Lags and in offline games too.
And I know that I have got a very good connection in my country so that wouldn't be the case.
The phone itself is also new so the phone is not the problem, Software I would say
The thing is, my mobile data Connection is worse than my wifi connection.
It is not really the best, just for WhatsApp and so on
I'm out of ideas. I googled a little and other people who had such problems had either bad net latency or something running in the background. I agree that it seems to be some software problem but it's strange that it only happens with active WiFi.
I think it's Software related because my gf got the Mi10 and she has no Problems with WiFi connection turned on.
Let's hope that this will be fixed in the future.
I will Report that to xiaomi.
If someone finds a solutions, they can share them here.
So little Update from me,
Some of my Games that I play had an Update and all of them which had that Sound Problem with WiFi turned on have been fixed.
So NOW I would say it's a third Party App Problem or maybe a Android 11 compatibility Problem with some newer Devices.
