usb host, conectivity loss and fingergprint swipes - Sony Xperia XZ1 Compact Questions & Answers

Hello,
I have three problems with my phone.
1. USB host, a limited version of OTG, as I understand, works only if I plug the USB device before the phone boots. If I connect it after the phone has booted, it doesn't work. Restarting to get a USB keyboard working isn't nice, as you can imagine.
2. If I'm in an area with weak mobile signal, causing the phone to lose conectivity intermittently, it simply refuses to connect after some time, no matter how good the signal is. It has sound interruptions in this no signal mode, and eventually reboots on its own to fix it.
3. Some apps can intercept swipes on the fingerprint sensor and assign them to actions. This doesn't seem to work.
I tried different firmwares and lineage, but those three bugs inisted appearing. I'm not an advanced android developer, but I suppose this means the problems are in the oem or another partition.
My previsible questions are:
Has someone else observed one of more of these behaviours?
Found any fix?
If any dev is reading, what should I do to try to fix those? I already code, just not for android. Alternatively, should I ask this question in another area?
I can't send the phone in warranty.
Thanks.

Kaiser - Wifi problem (expert opinion needed)

Recently I've been having problems with my Kaiser connecting to my Wifi.
Here is what happens reliably (when phone on it happens more often):
1) Turn on wifi from comms manager (it searches relentlessly)
2) If I try to turn wifi off in command manager at this stage it hangs the comms manager - not even task manager will be able to close it down.
If I turn the phone off (button) then it won't turn on again till a soft reset.
3) soft boot or remove battery - Kaiser comes back with wifi connected immediately most of the time however, it can also come back still searching in which case repeat soft reset or hard reset.
4) Once connection is established - I can connect / reconnect ok till the device is turned off then it happens again. If phone is off it appears to happen more reliably but I've not tested this enough, it happens either way eventually.
So phone on is 95% reliable but can be ok for a couple of times.
5) Once the wifi is in search mode the comms manager is useless and this continues ad infinitum (any attempt to turn wifi off will hang CM) and always a soft boot will bring the device back with a connection established to my wifi point.
Here's what I've tried:
1) Soft boot / battery removal
2) Hard reset without restoring any kind of back up -ie virgin restart
3) Hard reset without allowing custom install of t-mobile software.
Details of my device:
1) T-mobile Win mobile 6 - original rom
2) Hard SPL : SPL-1.0 Oliprof (CPLD-8)
so the only thing I've done to this machine is installed Oli's Hard SPL.
It appears therefore that no software is causing the problem. I am wondering if there's a possibilty of the Hard SPL causing a problem through corruption or do I have a hardware fault with the radio?
I'd be grateful for any help on this as to what I should do next. Please don't tell me to load win6.1 as this worked fine till now so isn't the problem. The only thing I can think of is to re-do the hard spl.
EDIT: Well I've just reloaded Hard spl 1.0 and the problem is the same so I'm out of ideas.
Just a few thoughts - although I do not have problems with my Kaiser, I have met problems with other folks.
1
Is the signal quality good - we know the range is not fantastic, so it's worth checking:
Start>Settings>Connections>Wireless Lan (Icon)>Main and look at the Signal Quality.
2
Start>Settings>Connections>Wireless Lan (Icon)>Power Mode(Tab) and change to best performance.
3
Does it do this with other networks? Don't rule out the Router creating difficulties.
4
Do you let the Kaiser go to sleep mode with wifi connected. If so I'd advise you terminate the connection in comm manager and turn off using on/off button rather than allowing auto sleep mode.
5
It might be better to allocate a fixed IP address rather than allowing the router to set it. Hangs can be created in the IP allocation stage.
6
Do you have any applications set to auto collect data? These could be weather apps, mail, time sync, quick GPS etc etc etc. If so you can try disabling those settings to ensure the crash is not a conflict between setting up the connection and simultaneous data collection.
These can be pesky problems to track down. I suspect that many of the above would be ruled out by your clean boot after a hard reset. If it always works initially after a hard reboot though, it does suggest that another app/process is interferring at a later stage.

Thanks Mike for your valued input.
Just to answer the questions:
1) Yes signal is excellent (I connect in 3 cycles of the animation plus after reboot it connects immediately)
2) I've tried these options - my current setup worked perfectly before, plus of course a hard reset and clean machine displays the same problems
3) I haven't tried on other networks but I've eliminated the router as the problem. I've tried dynamic / fixed - I normally allocate ip via the router plus lock down mac addresses. opened the system. However, this doesn't surprise me because I can cause this lock up without a connection. It's more rare but for instance, if I turn the phone on and delete my signin, normally this pops a dialogue asking which network to connect to. Sometimes that doesn't come up and it still hangs. It is more rare though.
4) No
5) yes tried all optons
6) No and especially not on a clean machine.
I've had the device for some time without any problems so something has changed quite radically which makes me think h/ware. If I were diagnosing this on a pc I'd be looking at both H/ware or a possible driver problem as it the network adapter is locking when it's accessed, however, on this device I don't see the logic of drivers unless they can somehow corrupt in rom even after a hard reset. Is that possible or heard of?
One observation is that when I get the hang and I try to look at the wifi settings I get the following message:
Code:
"To configure your wireless network, please enable your wireless network card".
This little clue seems to point at somethhing that's caused the adaptor to cease responding but somehow in the process locking the comms manager up (ie. if I goto comms manager and try to turn the wifi off, I'll get the spinner ad infinitum). Yet a reboot will kick it back into life again. And notably once it's running, and providing I don't switch the machine off, it'll work till the cows come home perfectly reliably.
I guess my question is whether there is any possible software cause that could exist AFTER a hard reset? Also the reliablity of this problem is enhanced considerably if 1) I have the phone turned on and 2) if I turn the machine off and back on and try to reconnect. Maybe that could indicate a power issue making the adaptor die I don't know what else would make the adapter lock up.
So far I've re-installed the (same) radio and Hardspl and neither of these have changed anything. I could of course go the final step and install the rom again but I haven't done yet as I wasn't sure what components other than the radio might be relevant in the rom.
Edit:
If it always works initially after a hard reboot though, it does suggest that another app/process is interferring at a later stage.

Just to clarify this: Wifi connects 90% after a soft boot initially. A hard reset makes no difference to the behaviour.
It may be a hardware issue, but it would be last on my list of suspects. (I KNOW it must feel as if you have tried everything already – and I think perhaps you have!!!)
Just a couple of further suggestions – since I am certainly not sure where the problem lies.
Having done a Hard Reset, I would 95% rule out a software issue on the phone (though it is possible with corruption of original data – but a remote possibility I think).
I hesitate to suggest a router factory reset, but it may be worth trying.
Two more things to try:

I am curious about why having the phone enabled causes more crashes. Have there been any phone network changes in your area. It crosses my mind that there have been a few reports of wifi problems when 3G is being used. Perhaps you could, as a test, try limiting the phone to GSM only and then testing wifi:
start>settings>phone>band – set gsm on both drop down lists.

There are a few reasons why I didn't spend more time on the router once I'd established a few things:
1) The adpator actually hangs and it causes abnormal behaviour on the machine. ie. comms manager hangs if you attempt to try to turn off wifi and the spinner comes up. Even more abnormally this causes one of two scenarios, either a) the machine no longer turns off or if you manage to turn off it won't turn on again. So it's causing a major problem with the whole system.
In my experience a no-connect situation never results in a hang, it just times out and a list pops up of other alternative wifi networks it's found and you can always just turn wifi off or use the machine normally at this point.
2) Wifi connects to my router no problem, always has and still will first time from a boot (providing I tried to turn wifi on and it failed before the boot). After a hang and reboot it comes back always connected - doesn't even search, it's a solid non animated connection icon. In other words the card has woken up and therefore has no problems with my router once it's alive.
As an outside chance that the router is getting confused about a disconnect / reconnect I've also rebooted it in between just to make sure - but the router can't tell my machine to hang or fail to respond.
3) I have managed to get this to hang after deleting my settings, ie. stopping it from logging on to my router but rather letting it come up with a list of wifi points it's found. Most of the time the list comes up but after several tests I've confirmed that it does eventually happen. The symptoms are the same when it does. At this point no list appears and we end up with the same deal as in 1)
Having said that I can give the router a try - resetting it isn't too much of a problem as I can backup my configuration but I'm pretty certain it's not the problem bit when problems get wierd then logic sometimes goes out the window and one has to try everything.

I'll follow the registry one just in case but both those threads seem to be from people who can't get a wifi connect at all, usually for s/ware reasons. This is different to my problem which is an abnormal adaptor / system hang caused by accessing wifi.

I'm curious too. I thought a problem with the radio as a whole but I've tested GPS and bluetooth without any problems, both on plus the phone. I also thought that some kind of power issue. If the voltage to the adapter for some reason dropped below a certain point it would kill it till it was kicked back into life. Just a theory. What would cause this, I've no idea, faulty component, dry joint perhaps.
I also had similar thoughts as you on possible changes to the phone service till I finally found it could hang without the phone too just less. This is like 30% to 95%, but multiple on/ off of the wireless and a couple of machine power offs will get it to happen when the phone is off. It just takes a bit more encouragement.
As for 3G I have mine disabled. I only ever turn it on if I am out and need internet via my service. I got caught out when T-mobile's 3G kicked in, in my area and my battery life went to hell about 18months ago - since then it stays disabled.
EDIT: This may or may not be relevant but I hadn't figured out which situation causes failure turn off. If comms manager is hung after a trying to turn wifi off the machine WILL turn off but not back on again. I just found that one other dialogue that hangs is going into the Wifi settings > network adapters > IEE 802.11b/g wifi adapter. This dialog hangs solid. At this point the off button does nothing. It's a reset. Just a strange reversal but it's also a confirmation that the adapter itself is the problem or has been put into a very nasty state.

[Q] Phone will connect to open wifi network but not secure ones

Had my phone for a few months now and recently found that it can't connect to my secure network at home.
When I turn wifi on I get the dreaded connect/disconnect message while it constantly tries to connect to my network. If I leave it on then the battery will drain overnight while the phone tries to connect. I have an iphone which connects to the network no problem. As does my laptop etc
To try to fix this I deleted all my new apps, especially the push ones which give me news updates, etc but this has made no difference.
The weird thing is if I turn off my router's security then the phone will connect and works perfectly fine. I've tried using all the different security settings (even WPS) with new passwords etc and everything seems to setup fine on the phone except it just doesn't want to connect (or more accurately stays connected for a microsecond).
If I go back to an open network it connects immediately and stays connected.
I think this is the root cause of the wifi connection problems that many other people are getting. But I'm at a loss to try to understand why it won't pick up a secure network but works fine otherwise.
My phone is using 2.2.1 and has been rooted
Any thoughts?

Root the problem highly unlikely ..
Secure home network test .
Remove security from Router that is no password .
Remove that connection from phone .
Reboot phone let it pick up router and connect .
If it does then delete reset router password and add in phone .
jje
Thanks for suggested fix. I'll give it a go and let you know if it worked.
Root was a bad choice of word..... I meant that while looking for a solution to my wifi problem I noticed many other people complaining that they can't connect to a wifi network for one reason or another and I was thinking that maybe broken security is a common cause of many wifi connection issues.. In my case there was nothing physical at all to suggest that security was an issue, especially since all my other devices work fine on the same network.
Cheers
Hi, tried your suggestion but I still cant connect. The first time I rebooted the phone it knocked out my internet connection! I've setup a static IP address for my PC and the phone was insisting on trying to connect using the same address and creating a conflict. I fixed that so that's not the issue.
This is what I've tried..
I checked to make sure DHCP was enabled in the router, rebooted everything. No luck.
I tried adding an IP Address Reservation for the phone and assigning a dedicated static IP Address. No luck either
I tried connecting the device using WPS. It all went as it should - my router saw the device, added the mac address to the list of devices etc. The phone acknowledged the handshake. But again it still wont connect.
I checked the router log and it says "DHCP IP: (192.168.1.2)] to MAC address B4:07:F9:336:3D, Tuesday, May 24,2011 03:08:48" which I think is what it should say.
OK I've just fixed it!!! Or at least its connected.
All along I've been securing the network with WPA2-PSK. I just changed it to WEP and the phone connected immediately. I hadn't considered WEP because I read that its not that secure and I do all my banking etc through my PC.
I've tried all the other security options and only WEP works with the phone. I suspect its a compatibility problem between the phone and my router (a Netgear WNT834B v2) because both the phone and router work independently but not very well together. There's plenty of posts discussing the Galaxy S connecting to WPA networks so it can do it.
Now, after trying all the other security options. It won't connect again even on WEP. Bummer. It is acting slightly differently in that its trying to acquire an IP address instead of simply not connecting, although it doesn't seem to be able to find one.
I need to try this on a friends network and see if the router or the phone is to blame. I've no idea... but the phone's a bit too touchy for my liking
I had a similar issue, I had to reflash the ROM to get it to work. Backup all your contacts and stuff and then do a full factory resetting. See if that helps, if it doesnt, reflash the ROM. It should work.
Well I've spent the last few days looking into this issue and it's considerably more widespread than I first realised. The problem is that while many people have a wifi connection issue we all seem to have variations on a theme.
As I say in my case the phone will connect and stay connected to an open network but won't touch a secure one. I tried many suggested fixes and nothing's worked so I am now trying a factory reset.
A couple of questions: there appears to be two ways to do this, a factory data reset through the phone menu; and a hard reset using a combination of volume buttons, etc. The hard reset seems to be the deeper of the two.
When you say full factory setting which one did you mean? I am currently data resetting and therefore using the "authorised" Samsung reset
But how long does this process take? My phone has had a black screen and been vibrating every 10 seconds or so for the last hour. It's getting quite hot and there appears to be no end in sight. Has the phone hung or something? If it has how do I get out of this without bricking the phone? It's beginning to concern me because I'll have to do something real soon.
As an aside, in my search for a solution I found something that might help someone people (it didn't work for me). According to the bloke who posted it, the problem for everyone is that the wifi drivers have not been installed properly and if you enter *#*#526#*#* on your keypad it unlocks a service access that reinstalls the wifi driver. I tried it and the phone told me the software was installed successfully but no change.
Waited long enough so pulled the battery out and restarted the phone. I get the startup screen but after that the screen goes black and it vibrates again every ten secs and I can't get in.
Have to try the other reset.....
Things are going from bad to worse..
Have managed to start a full factory reset using the volume, power and home button but it's gone back into the black screen and vibrating every ten seconds.
I know Im going off topic here but Ive now reset the phone, wiped the cache, tried to apply the sd card update (aborted because it can't find the directory) and it always comes back to the black screen and vibrating every ten secs.
Am now trying to reflash the rom. Oden reports that the flash was successful but the phone wont reboot. I tried a couple of times - one with Re-Partion checked and the other unchecked but neither will reboot. What could be causing that? I somehow remember that my firmware was JPH but I could only get hold of JPK. Could that be the cause?
I seem to have solved all the issues at last. Thought it was going to be a bit over my head for a spell.
Once I discovered that the only way I was going to get into my phone was by flashing the rom the first problem I came across was I didn't know which firmware my phone was using previously, apart from the fact it was 2.2.1 and from Asia. I guessed wrongly and after "successfully" flashing the phone it wouldn't reboot. I then noticed that there were only three variations of the 2.2.1 firmware for my region. The second one I tried went a little further than the first but I got an error message about the SD card. The third one installed no problem.
So I instantly checked the wifi signal and the phone connected to the secured network. And stays connected - so far about an hour and a half.
It's amazing how the phone deteriorated the way it did. Hope it doesn't do it again.
Thanks for any help/suggestions

[Q] USB connection not recognized

Hi all,
I have problem with connecting my O2X to laptop.
When I connect phone to laptop phone start to charge, but USB connection is not recognized and no notification on phone (top left corner) is shown.
It was working once, but since then my phone was updated via OTA to V10e and then to V10f yesterday.
My phone is on stock.
I've seen on other forum that people had similar problem but I didn't found any solution.
I've tried different USB cables, different laptop (home and business - on both was working once before), unnistaling drivers and similar.
Please help!!!
Thank You.
I have the same problem and I still don't understand if it is hardware or software related.
In my case the usb sometimes stop working for a certain time, sometime a couple of hour, some time for a full day. After that magically start to work again.
I've tried every in my knowledge but without success.
You are not alone

Using Topogigi 1.6 this exact thing hit me yesterday, I suddenly lost ADB-access (I was programming at the time, and suddenly couldn't upload the app to the phone anymore.) The "bug" top left had vanished, and no toggling of USB-debugging would turn it on again. I tried restoring froyo backups, tried wipe-install, didn't work. What finally solved it was to smartflash back to 10D. Very strange, I cannot find any logical reason for this behaviour, so it can only speculate it must be something illogical, like maybe overheating (wasn't overclocked.)
EDIT: Let me elaborate. When this happened I of course tried another cable, and what was extra weird was that it wouldn't even recognize a USB-connection, but it would charge. Plugging it back in the dock I normally use when programming would show a USB-connection, but no ADB. At first I was worried that perhaps the dock had pushed the pins in the socket too far in for the regular cable to get a connection. After smartflashing back to 10D though, both the dock and cable work as usual. So maybe, just maybe, a hot phone will expand certain areas around the usb-connection points either in the socket or on the motherboard. Again, just speculation. The usb-connection has worked fine since, using any cable.
Happened to me as well. In one day i can't connect my phone to the pc but after two weeks when i connected the o2x to a pc with vista the problem was vanished. I connected to my usual pc and the same it worked. let's hope that i will not have anymore this problem. It is possibility that your phone will revive i one day. good luck.
I think I may have solved this particular mystery, I'm now able to reproduce it at will, and get usb/adb functionality back.
It happens through a combination of ADB crashes/bugs on a computer and a usb-stack crash/error on the phone.
I can reproduce it by plugging in another phone/tablet on the computer (while still having the phone connected), installing/running something from eclipse on the other device, unplug and replug the o2x and then try to run/install something on it via ADB. This invariably leads to the ADB-icon (the status-bar bug-icon) disappearing, *and* it will lead to the phones USB not working on another computer, or even another port on the same computer.
Funny thing is, if I reboot the phone, and plug it back on the same computer, this instantly leads to the same behaviour. USB will only get recognized on the same port it was plugged in the last time, and ADB will still not get activated. Trying to connect to another computer *after* this will not work.
The solution is simply to reboot *both* the phone *and* the computer (or just kill adb I guess) before plugging in anything.
Plugging in the phone while *either* the PC *or* the phone is in this confused state will lead to both devices malfunctioning in the same way as before, which is why you cannot simply connect the phone to another PC. (Although unplugging the phone, rebooting it *before* plugging in to another computer should work.)
Thank You for info.
I just tried it but unfortunately it didn't work for me. I've tried restarting phone couple of times, plugin into different computers but phone still doesn't recognize usb connection (just charging).
I this the problem is in the phone and it maybe due to update to v10e and v10f.

Hm, okay, your problem may be of a different kind. I'm not entirely convinced yet, as you don't mention having rebooted any computer. So just to satisify my curiosity, do exactly these steps in the following order:
1) Unplug the phone from the computer.
2) Power down the computer
3) Power off the phone
4) Turn on your computer
5) Re-install the LG USB drivers
6) Turn on your phone
7) Connect the phone
If this doesn't work then you indeed have a completely different problem, and we're back to speculating.

Trym,
Does that mean you were able to smartflash despite having USB connectivity problems? I had these problems with my first O2X and after I flashed MCR I couldn't connect to USB at all. Luckily this was within the exchange period and I was given a replacement handset which hasn't had these issues but then I am still using stock 2.2
I did try all combinations of reboots on the phone and also driver installs etc on the problematic handset but nothing worked then.

You may of course have had a genuine hardware fault, after all usb-sockets are among the first things to break on any phone. I thought my phone was a goner as well, until I discovered the things mentioned in my post. It's a really sneaky affair, it would be impossible not to assume the phone is broken the first time you experience it.
EDIT: Removed invalid assumption.
Just to report that I've tried everything, including connecting phone to computer on which my friend runs Nexus S with no problem and then connecting to computer on which my phone was never connected.
Is there easy way to revert to v10d (last version I know my usb connection worked)?
I don't want to experiment too much because this is my business phone.
Maybe I'll just wait for GB and V20e (I hope it will finally be released soon) and hope that this will resolve my problem, but until them I'm missing one of main functionality
What a waist, since I get the phone with all that fuzz about it, is nothing but problem after another: rebooting, battery drain, wifi problem, usb connection... whats next?

Weird. Glad you got it working.
Looking around on different LG Forums, as useless as they are, the support-people always gives the advice that you should take out the battery, and leave it out for five minues to "clear residual memory." (This, apparently, is the solution for any kind of problem with the phone ;-)) That's always sounded completely nuts to me, but that's the advice I'm going to give the next guy with usb problems ;-)
And another one bytes the dust.
That's ultra weird. one minute everything is just fine and on the other, USB is dead.
So, apart from the procedure TrymHansen gave us a few post back, there is no known solution/diagnose/whatever for this problem, right?

Turn on mass storage" in the phone does not appear, it's like I'm just plugging in into a wall charger.
It could connect just a few days before, same laptop, same drivers (LG mobile united drivers)
Have tried it with 3 different laptops, still can't connect (drivers are installed)
A google search reveals other people having the problem as well and unable to solve it.
Can't return it yet for warranty because superuser app is still there.
Originally, I rooted it using superoneclick. Can't unroot it in superoneclick since not detected in USB.
So i unrooted it using z4root (without a pc). It's now unrooted, however superuser app is still in the app drawer.
i believe mine can be detected from smartflash so maybe i can flash stock rom. will doing this remove superuser.apk?

So did you try to flash a stock rom and did solved your usb problem ?

strange is, all the other usb devices (wifi dongle, not keybord mouse) stops working when i plug in my phone? also the phone does not see that there is an data cable in him so i cant mount my storage?

[Q] Hp TouchPad running Android - Wifi force close

I've tested this with a3.5, Xron and Miui and they all get this problem. Maybe installing certain apps trigger this to happen but wifi will eventually slow down when trying to connect to a signal and will be essentially non functional since the OS will basically freeze and then tell you to force close wifi and it requires a wipe and fresh install to fix.
Has anyone else run into this problem?
Check this and see if it helps you.

I don't think its the same issue. In those instances you can still try to change which wifi signal you want to connect to, I think it just loops from connecting and it would disconnect. I think this issue is common and dropped connections occur as well.
But I'm talking about a situation where if you even try to enter the wifi options it will force close.

Before I changed it, it would take forever to get it to release the connection. I just kept hitting "Wait" rather than "Force close" it would take several minutes but would eventually come up and allow me to Forget the network.
It sure sounds like the same, not saying it is, but very similar.
I experienced this problem for the first time yesterday in area where was about 20 WIFI networks. Never ever it happened in my house on A2. A3 A3.5 or XRON2.8

I have the same issue today, Wifi setting is forced to close, and cannot connect to any Wifi signals. I think it's a bug and it related to the time or date. Because I didn't do anything and it just happened.
No new apps install, no setting changed, and the device was keep on, so it just happens.
Hope someone can find out where the problem is...so sad this happen on New Year's eve....
i have this problem also, the solution i found was letting the touchpad go dead and than begin to connect wifi again.
Similar wifi comments here: rebooting [or maybe toggling/other disconnect] with wifi on/remembered would get it into a state where it was scanning and connecting over and over without really ever working. this was only happening once it was 'remembered'. Going through the wifi settings to forget in this state involved hitting 'wait' a few times and then i'd reboot and readd. 1st wifi connect is always solid for me.
I've found: market.android.com/details?id=com.brilliapps.wifiandmorefixer
Does the same thing except it is one click. I rebooted after the first go, but now no longer. i run this and then readd wifi - all set.

Impossible to connect VPN/Use NPM (Firewall blocking) ?

Hello,
I have a very annoying bug which is really strange when I use my mobile data and do a tethering.
It is impossible to connect to a VPN, I have a connection timeout error.
I am a NodeJS developer, and it's impossible to download any dependencies when tethering. I have a connection unreachable BUT it works when I download NodeJS on termux and use the package manager.
I am suspecting that the problem comes from an UDP port blocking but I'm not really sure.
I am absolutely sure that the problem comes from my phone. (I've tried to use an other SIM on my phone and it still doesn't work, but if I put my SIM on an other phone, it works)
I did a factory reset twice, relocked my bootloader, but the problem still remains.
Did you have already experienced this problem and how did you manage to solve it ?
Thank you
