[Q] GPS problem: fix -> lose fix -> fix -> lose fix

I'm using CM7 on my Nexus One. The issue happened twice; right now the GPS is working fine but I'd like to find what can be done to diagnose this, or if there's anyone out there who already knows a fix...
Here's what it looks like:
I turn on the GPS, open GNavigation (or Waze, or Maps). GPS gets a fix but when I start driving, it doesn't update my location. After a while, it loses the fix, the reacquires it, still doesn't update it, loses fix again, and this keeps happening as 5-minute long loops.
Here's how it looks like in the GPS Status app:
It's as if GPS gets a fix, then hangs (my coordinate are not updated in GPS Status app) without giving any errors, then turns itself off and on, gets a fix again, rinse and repeat.
What I tried:
Reset and download A-GPS state. Reset dalvik cache using recovery. Reset A-GPS state, turn off GPS, turn off phone, turn on phone (and variations of this). Didn't work...
What worked:
Finally I got sick of it and took out my real GPS device. I didn't turn off nexus' navigation (wanted to torture it a bit out of spite and frustration).
After driving for 40 minutes (and nexus finding, losing, finding ... GPS fixes as I was driving), suddenly it got a fix, and it just started working again without problems.
Anyone know what's happening here and how to fix it? Thanks so much in advance

You are not alone
Rebooting almost always fixes it for me. Unfortunately it takes several minutes.
Airplane mode also instantly fixes it, but then you lose A-GPS and all communications.

Radio updating may fix the problem.
Try flashing a latest radio image.

Latest radio
Thanks. I guess a new, functioning radio would indeed solve the problem.
However, I already have the latest radio flashed: 32.50.0032U_5.12.00.08 for the Nexus One. Earlier radios have other heavy shortcomings, so they are not a good option.

i wold know if it was good be4
cuz it was worked fine but now ive same problem
i thought this problem form rom
but now i dont know the reson
sorry 4 broken eng
thx

I am waiting for ICS and hope that will fix it.

[Q] Blank screen issue??

Has anybody still have the blank screen issue?
Mine did it last night blank screen but the hdmi is still working when hooked to my tv.
Is there a software fix for this? I am on the stock 10.26.1.18 4.3 JB.
The touch screen still work when hooked up to the tv though hdmi just the screen is off.
Is it something to do with smart saver mode or display sleep.
I used the hdmi hookup to factory rest and shut off and when I plugged the tablet back in the screen started working again, I hope somebody can help because I really love the tablet otherwise.
Thanks

You could have a loose connection or your backlight may be on it's way out....
But if it works now - just enjoy it!
To rule out software you can either:
a) reflash the same firmware you are on now
b) flash one of the KitKat updates. You are 2 updates behind on the latest firmware for this tablet
Quite a few users are reporting massive battery drain during sleep on the latest 11.4.1.27 firmware though. Don't know if I can recommend to update to that right now..... You cannot go back once you updated!

It seems to be working now, I factory reset the tablet twice and shut smart saver off, I hope it keeps working the tablet is fast and can do everything I need it for. Do you know any stress test I can do on the tablet to see if it happens again?
Thanks

[Q] Lollipop update -- gesture launch broken?

Updated my M8 to Lollipop OTA the other day, and since then gesture launch stops working occasionally. It has happened sometimes twice a day, sometimes after a couple of days. I have to restart the phone to get it working again. I only had the phone for about three weeks before lollipop, but gesture launch never stopped working during that time period. Anyone else experience this? Anyone find a work around other than restart (turning gesture launch off and then back on does not seem to work). I wonder if a factory reset would fix the issue.

Turning on bluetooth crashes the phone

Hi, a few months ago I've noticed that when I try to turn on bluetooth (which is usually turned off) everything freezes the moment I 'click' on the turn on/off switch. After the freeze it takes around one-two minutes to restart the phone and then I can normally turn the bluetooth on.
The strange thing is that I can turn it off and on then and it will work, but when I turn it off and leave it off for a few days, and then try to turn it on the phone will freeze again...
Did anyone had the same issue?
Android version: 7.0 (B394)

I installed B395, but the problem hasn't gone away. Anyway, for the first time after this 'freeze' the message box saying that 'the interface app stopped working' showed up and I could 'stop' the interface app.
However, the update did not solve the problem.

Same problem here did you find a solution?

Same problem here for years! Android 7.0. Did anyone found any solution yet?
My build number is EVA-L09C432B505. Stock firmware, regulary updated.

@zozo77, Have you regularly updated your stock firmware?
What is your full build name/number, like EVA-L09c432b504 or what?

*SOLVED* Galaxy S10 rotate sensor issues after update to One UI 3.0

*SOLVED*
Hi all,
Have my Galaxy S10 SM-G9730 Dual Sim (unrooted) for about 18months now and has never skipped a beat.... until the new One UI 3.0 update that I got a few days ago.
After a restart everything works fine then after 15min-2hrs I will lose auto rotate, screen brightness is also less responsive (proximity sensor seems to be ok). Toggling auto rotate/adaptive brightness on/off does nothing.
Same issue across all apps (Youtube, Camera, Messaging etc.)
Going to the *#0*# - SENSOR menu shows me that:
Accelerometer Sensor is responsive (x, y, z axis all change to reflect movement) but the "IMAGE TEST" doesn't rotate the image of the dog. Should it?
Gyroscope Sensor doesn't move at all, is it supposed to? "GYRO SELFTEST" shows a PASS.
I downloaded the app "Sensor Test" and most of the sensors give me the error:
"This sensor doesn't report any readings, seems you have error with sensor service in device firmware"
I have tried the following:
- Toggle auto rotate on/off.
- Restart phone (using power button - restart & using power & Vol down combo)
- Cleared cache from Bootloader menu.
- Settings - Apps - Reset app preferences.
- Factory reset (using both settings - Factory reset & using bootloader factory reset)
I have a feeling it is an app that isn't updated to run on One UI 3.0 but I have no way of finding the guilty app.
Called Samsung who were no help (try restart, try factory reset, send it to us but we will charge you as Samsung don't have international warranty , even though yes we agree that it was our update that probably caused it)
Seemed to be good for about 10 hours after the factory reset but came came again,
Anyone come across this and found a way out?
*edit* just checked after restart and Gyroscope Sensor shows values after restart (while auto rotate is working), This leads me to believe it is 100% the gyroscope at first which in time leads to the accelerometer also not working.
*edit x2* well I've just restarted my phone then went through every single app 1 by 1 (downloaded and bloatware) and checking for rotation after each app launch, that is: launch app, test rotation, close app, test rotation and do that 172 times!! I task killed maybe 5 times during the process..
after opening every app I still have auto rotation which leads me to believe its some system background process and not a 3rd party app issue. Damn..
Is there any way for me to monitor these? or monitor sensors stopping functioning?
*SOLVED* See post #6 below

I have same problem. After updating to one ui 3, the rotate sensor stops working after a while and only a reboot helps. Galaxy Note 10+ N9750 (snapdragon). Can't find fix yet

Same problem, autorotate feature is not working after software update (Samsung Galaxy S10 SM-G9730, One UI 3.0, Android 11)

Same thing here! If you read this please send a bug report to samsung we we can get their attention.

Didn't see anything on Reddit about it may be fixed on 3.1
Let's find out

*SOLVED*
Ok then, finally seem to have this sorted.
What I ended up doing was:
Downloading the latest firmware (the firmware that caused the problem) using frija.
I took a complete backup onto my laptop using Smart Switch.
I then flashed the firmware using Odin but again after a few hours sensors started to drop off again.
I then flashed the firmware again using Odin but this time I performed a nand erase while flashing.
Pushed my backup back onto my phone from my laptop using Smart Switch.
And hey presto!
This seems to have sorted it, I'm now well into day 2 and still working 100% which is the best it has been since the OTA firmware update.
Hopefully that will help others

My phone is doing this as well, I've got a US unlocked phone overseas as well. I followed your instructions and did the nand erase but after 2 days the sensors started messing up again.

It's the firmware..samsung is releasing buggy firmware..received 3.1 update yesterday... seems to have solved proximity and autorotate issue..smartview and NFC still not working for me.

So they force us into an update that breaks the phone and don't let us go back to the previous version of the software? That doesn't sound right.
Another marketing scam to get us on to the S21.

Same problem with S21 Ultra after Android 13. Rotate sensor flips 90degrees after some day or two of use. Now it was messenger that was active when the flip came.....
Any solutions apart from reflashing via 3rd party? That's quite a job to reset the phone.
Thanks!
