HSDPA Problem

Hi, not a big problem as I am normally on wifi but I've noticed that my GSII is constantly dropping of HSDPA every few seconds and if I do a speed test it only gets around 300kbps.
Now I have an LG Optimus on the same network, same room and that stays on HSDPA and gets around 1800kbps on downloads.
Any idea what would cause this?

Hi, is yours a SIM Free or is it on a network? Mine is SIM Free.

Don't have another phone here right now to test against but just did a couple of tests with speedtest.net app
Download/Upload
2500kbps/1967kbps
1422kbps/2967kbps
6192kbps/2883kbps
2896kbps/2608kbps
Seems to work just fine here at least. Granted this is at a place with good HSDPA coverage.

Sorry to tell you that but it seems like a bug in the phone, i do have the same issue, i surfed the couple of forums and the problem is spreading, hoping it's not a hardware issue.

i got 7184kbps/1774kbps

I think I'm one of a very few who has an hspa+ phone in the region maybe that's why
goes down to 2mbps when it's lower signal.

Yes I think it's a phone issue as my HTC Desire and LG Optimus are both working fine.
Hmmm. I hope this can be sorted with a software update.

mine too, infact wont go over 1900 had like 3500 on my iphone 4

Just updated to the newest firmware using Kies and it made no difference to the problem with HSDPA :-/

I think it's a network restriction. People in another thread were having similar problems with buying the handset and the contract separately meaning the data plan they were on was only at 300kbps.
If you've got another handset that gets a higher speed, switch the sim cards and see if that changes anything.

My phone will only download around 360kbps but will upload at 1mb, so puzzled as to why it would be a network restriction (hoping it is as I'm not happy and still within my 14 day cooling period) ringing o2 later...

No, it's not a network restriction. Not on Three anyway. I've just taken the PAYG SIM out of my LG which is getting around 1800kbps and put it in the Galaxy SII and it now only gets 64kbps!!! It's constantly flickering between 3G and HSDPA. It's definitely a phone issue.

i had posted in the other thread about how it switches down to 3G when it's not being used and instantly switch over to H+ when in use. There were no performance issues
Also on AT&T network, when it's first started/activated it took a little bit of time before network performance improved both on day one and when i switched over to an unlimited data plan

Oh I forgot to mention. I reported this issue to Samsung yesterday but don't hold your breath!
The man I spoke to didn't seem to understand what I was saying and when I advised him that there were many similar problems and issues being faced by people on this forum, he simply stated that he had never heard of the site. I gave him the web address but doubt they will ever look in to it.
If your facing this issue, then I would ring them and report it. That's the only way they are going to find out about the issue.

Normal behaviour for it to sit on 3G, only switches to H+ once it's in full flow.
This usually impacts speedtests and such.
Best way to test is to download a file off a fast server.
Same thing use to happen with my Desire.

I have numerous 3G devices here and none of them cuts of HSDPA so erratically. If I start to stream AudioGalaxy on my LG Android, the HSDPA stays on as does my Huawei MiFi. The Galaxy S II is dropping connection every few seconds.
It doesn't make sense for two Android phones in the same room with the same network to get completely different speeds. Maybe a small difference but to get one having 1800kbps and the other 64kbps shows there is a problem.
I've just updated the phone to KE2 and it's made no difference. Will have to wait to see what Samsung say.

How strong is the signal in dB or just bars whe nit switches around between 3G and H/H+?
That last sentence - did you contact Samsung with the problem and are waiting for their reply? thanks

It's around the -100 dBm mark with 2 to 3 bars. Yes I contacted Samsung yesterday and am now waiting for a reply.

Xperia play reception problem ...

Hey everyone and tnx for reading this.
I am experiencing some reception problems with my play today.
Just started to happen today.
Here is wat happens. Out of no where (and i really mean out of nowhere!) the phone has no more reception or connection to 3G or wats so ever. Ithe icons show a diff story. The reception level is full and then internet is showing 3G as normal. But i think they hang. Cuz when i use data the 3G icon changes to H.
anyways this has happened over 10-15 times during the past ten hrs or so. My friends are saying ur phone was off or out of service and im at home where i always have perfect reception.
I didnt install or remove any app.
I didnt play with settings.
I try putting it in and out of flight mode. Sometime it worked. Not everytime tho.
I tried restartung the phone. Reinserting sim and batt. Also tried searching for network manually. But i keep losing reception. Any idea?
Thanks

G is slow speed.
E is medium speed.
H is broadband speed.
Go to wireless and networks to change to GSM only (permanently slow but better reception) or WCDMA only (permanently fast but probably worse reception based on how developed your carriers communication infrastructure is).

Its rogers. Im in canada. Its not the network. I have been with them for years and i have had the Xperia play for over a month now. Never ever had a problem with reception. In fact its amazing.
As a matter of the fact u kno this is the problem from my phone. Which is most lijely software since i had my friend sitting next to me with his Bb he is also with rogers. He was fine bue wen he tried calling me mine said its out of service. Also i couldnt make a call to him. A few mins later everything got fixed and again it got messed up. As i said at all time the reception bar is full! But its not real since i jave no rec.
Any ideas?

GSM and WCDMA work differently and independantly. Your old Rogers phone probably worked using GSM.
WCDMA is not as well supported and could be considerably worse reception even though it is with the same carrier.
Go GSM only and note if the reception is better.

Ye i understand. I'm just trying to throw some idea in the air to help you. I can understand how much of a frustrating problem it could be.
Lets' clarify -
1) You bought Xperia Play, worked perfect
2) After a month, your phone shows a good signal, but when friends telephone you it goes to answer machine as if you had 0 signal?
3) Basically all reception is lost and you have no signal, but sometimes it shows you do, even though you dont.
Here's some things to try -
1) Put your sim card in another phone and note the behaviour. Does it stay a strong signal? If yes, then it has got to be the Xperia Play at fault.
2) Put another sim card into your Xperia Play. Does it stay a strong signal? If yes, then it is actually your network provider at fault. If no, then the phone is at fault.
3) Try resetting the whole phone to default. Does the problem persist? If yes, then it is a hardware fault. If no, then problem solved.

Thanks a lot. I did restart it to factory defult yesterday! didnt help! I even reinstalled the whole software using SEUS. nothing is changed.
I know the service provider is fine since my friend sitting next to me had perfect signal. he is also using the same network as i do.
now I am jus waiting for my brother to come home. he has the arc. same network. im gonna double check the sim cards and if its the phone i will send it for repair!

I am having the same problem with mine and reception, I don't know if 85dbm is supposed to be good but I am used to having full bars in my house. I only get about 2 now.

Reception for me is terrible. Used to be a lot better on my crappy old samsung gravity.
Drops to zero bars constantly, and often says no service when inside the house.
My wifi stops working the second I'm out the front door too. Wifi works fine across the street for all my other devices, including a laptop and a samsung captivate.
This leads me to believe the radio transmitter is a defective design. I'll be calling my provider tomorrow.
Edit: wifi doesn't work now at all.
The phone's wifi icon shows it as connected, but theres no transfer of data, router doesn't see the device as logged in.
Some google searches have revealed this to be a common defect. I for one am not pleased.

Just holding the device lowers signal!!!!
I know that sounds like crap but in the instruction manual it says not to cover the back fo the phone as it affects the signal.
No two ways around it, the phone has issues. I have taken it to carphone warephone and shown them it going from 4 bars to 1/0 bars just buy holding it. As it is over 14 days I am screwed. Whats worse it tha that had stop selling the phone to new customers as it has so many issues.
If you look at your battery life, then click on it you get the graph which shows signal. On mine were it say awake / screen on. i.e. you are holding it, the colour goes from bright green to dull green in perfect unison.
I am currently on my 2nd phone, the first one had 5 different faults. I now have 4 batteries due having to use moxier mail as the stock mail is sh1t. unhappy times

Hi guys!
I'm sorry to hear about your problems with Xperia PLAY.
I would suggest that you try some things before considering leaving it into your retailers for a check by a service technician.
Double check that the problem is not caused by an old SIM card. Old SIM's and new phones can sometimes cause troubles. So please try with a later SIM card if possible.
If that doesn't make any difference you could reinstall the phone software or update to Android 2.3.3 which is under launch right now. When the update becomes available for your device differs from market to market and is also depending on operator customization.

Just a warning, if you unlocked Bootloader ! using FOTA or SEUS very likely will result in a non-usable handset (bricked) !!!!!!!!!!!!!!!!

I was having trouble with that also.
I changed my router to 802.11G only. I have devices that do not support n so i went with G. it took a day or two but but it fixed it.
to get it working when it does that you have to disconnect and then reconnect.

Losing signal on my Nexus S

Hey everyone,
I just bought a refurbished Nexus S for $200. I thought it was a pretty good deal. Loving the phone so far. However, last night I lost data services. The signal bars which is normally green was "greyed" out. I tried the web browser, twitter and nothing was working. Eventually I got data back in about 30 mins or so. I didn't think anything of it. Well, it happened again today. Signal bars were greyed out again. I have less than 14 days to return/exchange my device. Should I exchange it? Is this a known issue with the Nexus S? Just an FYI, I have 2 lines and data is working fine on my BlackBerry.
I'm running stock OS, 2.3.6
Any help is greatly appreciated.
Thanks

Hate to break it to you but one of the few bad things about this phone is its reception. Check what radio version. Your on. If it doesn't say ke1, go on peter alfonsos web site and download the ke1 radio and flash it through cwm. See if that helps.

I'm assuming that requires me to root the phone? So if I choose not to root my phone I'm going to have this ongoing issue?

rooting and installing this radio won't necessarily help. I have the I9020A with the newest radio and i do have this problem sometimes - I'm losing signal and it recovers in random time. the weirdest thing is that I can find my network when I'm searching manually for networks. You are on rogers (based on your avatar), so i can only guess we have the same model. My brother has the I9020A also, and he has similar yet different problem - when he lost signal due to no reception areas, he has to go into airplane mode and back to normal to recover the signal. he also has the newest radio (UCKF).
You should also notice that rooting your phone will make you lose your warranty, and i guess that also the the right to exchange it.

Yes the model I have is the same as your brother's. I know in general Samsung has bad radios. Is it because it's made by Samsung or is it particular to the Nexus S? I have been reading the same issues with the Galaxy Nexus, so I'm guessing it's Samsung.
I don't plan on rooting it because I know it will void the warranty and I won't be able to return/exchange it.

i have same case , which is , when i am back in my room ,away from streets and lots walls for signal to go through , 3G signal is **** , however, you can switch it to 2G signal in order to no to miss any phone calls and SMSs. but , you Internet speed will greatly reduced ... like max 8 kb/s

You should see if your phone is set to wcdma/gsm mode. My room is a inner room also and when it loses 3g signal, it jumps automatically to gsm mode (internet speed is not an issue, WI-FI FTW ).

Well I do have an ns4g and since these forums aren't seperated by model its easy to see why I would make the wrong recommendation. What are you following me around? Instead of being a troll why don't you post something useful and try and help the op bud.

What Radio do you currently have?
I usually had this problem and I had to go into mobile network settings, uncheck 'Data Enabled' and select 'Network Operators' until it found my carrier.
Have you tried checking the Airplane mode and disabling again?
If you dial *#*#4636#*#* when this happens and you go into phone information, do you see it connected?

Aaaargh fecking signal!!

Why does my phone show full signal yet all apps that use mobile data either run shockingly slow or not at all!! My steam app is constantly reconnecting yet signal is constant! In BBS it's showing i have good signal for a matter of minutes and is mostly showing poor or unknown signal nearly the whole time the phone is on!

Could be you only have full bars of 2G data speed. You are either being throttled for excessive use from your carrier or your carrier only has 2G speeds where you live. Where I work the entire county only has 2G Edge speeds from AT&T even though their coverage map shows 3G for the area. Check your data type and speeds with an app like Network Signal info.
https://play.google.com/store/apps/details?id=de.android.telnet&hl=en

Happens to me a lot as well. I show full 4g and yet everything times out and wont load because data is so slow. I'm also in a good coverage area where i get 12-14 Mbps speed with other phones and when this one is acting normal.

The towers you are connecting to are probably overloaded. Thin of them as a wireless access point at your house with 1 internet line. If too many connect to and use that line, the connection gets slower. Would be nice if cell providers posted tower stats in your area. Would save a lot of angry calls

I think in my situation it is not this. My wife has an HTC one s and my brother a sgs2 and they will have great data speed while i have dead slow even though we are on the same carrier and in the same room.

Glad im not the only one suffering.. I didnt really have the problem on stock so much.. just since unlocking and flashing new roms.
To the person who mentioned carrier throttling, its certainly not that as one minute i'll get full speed and the next (youtube for example) will just stop and start saying no signal retry and then if i turn the phone off and back on again it will work. How can a carrier throttle you when you only have a 2Gb usage limit and then they charge you afterwards that makes no sense.
Also its not a 2G problem as Signal checker shows 3G and also now EE all around my area. Besides my wife's S3 on the same network is getting full speeds where im not or anything even though im apparently at full strength H
I hope this gets sorted soon as its also affecting calls.. I'll have what looks like full signal while playing a game then suddenly a text to say someone tried ringing me like 3 minutes before!!

probably switching from HSDPA to HSPA+.
did you notice a H on top of your signal bar, that switches to H+ when the lag is over?

I have had this problem for a long time, since I got my Galaxy Nexus and now again on my Nexus 4, and finally got so fed up that I have been testing it all day and getting screenshots ready to make my own post about this so I am pretty relieved to see this post!
I live in Philadelphia and use T-Mobile. I have had T-Mobile here for years and never had this problem before. When they upgraded to 3G I had amazing speed boosts and when they did HSPA+ it got even better but that was on a G1/G2. On my Nexus phones the internet is damn near unusable in center city but what is so odd about it is that in my Google searches about the problem I can only seem to find posts raving about T-Mobile in the city and how Philly keeps getting improvements including the new improved 1900Mhz HSPA+42 but I have never even seen my Nexus 4 on the +42 network the best it goes to is +15 and even that makes no difference because the internet is so slow and unrelaible that unless I am on Wifi, my phone just sits in my pocket useless.
I'm really at my wits end about this and no one, Google or T-Mobile seems to take responsibility or have any advice on how to fix it except the pointless factory reset.
I've seen a brief mention on XDA about a fast.tmobile.com APN and I changed to that and I'd like to imagine that it showed some type of improvements but certainly not with data speeds/latency/integrity of connection. If anything, it may have improved signal 'strength' (used lightly because regardless of what my strength is listed as the connection sucks.
To be clear, I am connected to HSPA and HSPA+ when the connection is being used, like it should, but these are the best speeds I managed to get throughout the day today as I moved around campus trying different spots.
Please, someone have advice!!

Could it be kennel related? Did you guys try just being on stock ROM?

I am using the stock kernel, stock radio although not the stock ROM. I am pretty sure I had this problem before I rooted (I say pretty sure to be conservative with my answer since I am not 100% sure but I am definitely 90%)
Is anyone confident about their knowledge regarding APN settings? I have seen like 15 different configurations for T-Mobile's APN and have no idea which one to try and would prefer not to just go through them one by one -- I've got things to do!

Again.. I'm pretty sure i didn't have this problem while on stock but i could be wrong. My GNex was exactly the same. And I'm on orange UK so completely different network to the T-Mobile USA so surely can't be random that we're both having the same problems

I had the same slowness over cellular, 9kbps or so. I changed APN's, rebooted and just got 2463kbps.

Will this only work for at&t users though?

I'm on stock 4.2.1. Phone is rooted and boot loader unlocked. For about two days now I'm having signal drops from 4bars, then greyed out 4 bars and jumps between H to 3G. Settings for LTE revert to WCDMA every time I lose reception. Also dialer crashes/ force closes if I have an incoming call and sends all calls to voicemail. I can dial out but at the end of my calls when I go to hang up I see the popup that phone process crashed.
My carrier is Bell Canada and the phone worked fine for about 10 days before this started happening.
Any tips or advice to help me out is appreciated. Thanks.

Random Loss of Service on T-Mobile

So I've been having this problem for a while now. I've tried contacting T-Mobile about it but they've been completely useless. Basically, I'll lose service randomly and it won't come back for hours (sometimes it'll be gone the whole day). And I mean I can't make a phone call type of lose service. I live in a semi rural area, but there are still plenty of areas that have HSPA/HSPA+. I've tried new SIM cards, going back to complete stock ROM, no root. I'm at a loss at this point. Has anyone had this problem? If anyone cares, I'm currently on PA 3.15, .48 radio and latest boot loader.
Edit: Stock APN settings as well. And when I go to choose a network operator, both T-Mobile and AT&T show up, so I assume it's picking up some sort of signal, it just doesn't want to connect...

I get this sometimes. Sometimes a power off/on works. Other times it doesn't. It's never been for hours, only about 10-15 minutes total but it's really unnerving because it could happen at the worst possible moment. I think I've had this happen to me 3 times since I got my N4.

Would it comfort you to know that its not a error on your part but rather T-Mobile's?

Haha! I figured it was, just seeing if anyone had heard anything from T-Mobile about it or if there was a fix. Thinking of switching to AT&T because of this tbh

I would do the same thing if I was in your shoes.

Yea I'll constantly lose signal and that normally works but occasionally I'll get it to where nothing works and I'm stuck with a paperweight for the rest of the day (today being one of those unfortunate days)

Do you know anything more than that? Is this some sort of handshake issue between our radio and their cell towers? My wife is on T-Mobile and she doesn't have the issue so I presumed it was my phone.

My signal drops out a lot but I only pay 30$ a month so what can you expect

You're a customer, you should expect good service no matter what you pay.

I was having this issue as well. I would lose service for hours at a time on random days for like a month and a half. I found out that they were doing tower upgrades to get lte up and running (I'm in the north jersey/NYC area). Now my service is alot stronger and rarely ever lose service.

I'm in the suburbs of Detroit (White Lake for anyone who cares). I kind of doubt lte will get here any time soon but here's to hoping that's what they're doing, lol.

Thinking I might try to get a replacement phone actually. My roommate has a nexus 4 as well and he's had no problems whatsoever. Hmm... the plot thickens...

I've been having the same issue with both the original and replacement phone. I've changed SIM card too, it still happens. Each times it lasts for a few hours before starting receive signal again. So you are definitely not alone here.

Yea it sucks but it's definitely nice to know it's not just me. Too bad T-Mobile and Google just point fingers at each other as opposed to finding an actual solution...

Update: So I went ahead with an RMA and already I think I made the right choice. I'm getting 3-4 bars of H+ in my living room where I used to struggle to get a bar of 3G. So, I apologize to anyone who thought this was a waste of a thread and just cluttered up the N4 forums (God knows this forum needs to get decluttered), but if my experience helps at least one person out, then I guess it wasn't such a waste after all. Moral of the story, if your signal sucks just get it over with and go through an RMA (Google made it super easy and painless):good:
