[Q] G2X Battery Inidicator not displaying - T-Mobile LG G2x

Strange issue with my G2X. It has worked perfectly since having it replaced due to the reboots a month ago. An hour ago I used it just fine, sending a few texts and making a phone call. Now, I turn it on, and the phone no longer gets service and the battery inidicator (stock no roms) just shows a circle instead of the the green/orange/red charge levels. I tried putting it in airplane mode and back out to refresh the signal but it simply became stuck in airplane mode. Attempting to turn off airplane mode through long press just grayed out the option. Doing it through settings force closed Android.Settings after a couple of seconds. Pulled the battery and waited a little bit, turn it back on, still the same issues. Has anyone else seen this before with their G2X or other Android phones?

Try pulling the battery while the phone is still on?

I was able to find the culprit. Never would have expected my 8gb SD Card (Not internal) to be the reason my phone suddenly crapped out on me. Removed the card and the phone worked just fine. I'll replace it with a new one after I am able to copy my files off.

Strange Turning off by itself

Hi I'm wondering if anyones come across this problem where the Tab turns itself off. After serveral attempts to turn it back on it wont. Only way is to plug the power plug in and then turn it on, the battery is on about 80% charged so there it has nothing to do with flat battery.
Before I plugged it into the power plug it seemed to be hotter at the back than usual. Its not overloading itself out is it??
Its happened a few times but nothing major just strange.
Any suggestions would be appreciated
It was on stock P6800XXKL1 but moved up to stock P6800XXLA3 both had the same problem before.
i have the P6810 completely stock and have seen this once
Does it go through shutdown sequence or just instantly lose power?
Try charging it for a few hours with it turned off?

It goes through the shutdown sequence. Don't think charging it when its off will make a difference but I give it a try.

random turn off Galaxy tab p6800 7.7
I have a stock 7.7 and there have been a number of times when i find it is off OR not responding immediately to the power switch when i pick it up to use it. Ie power switch doesnt turn on screen. I assume it has shut down.
Battery is full.
bluetooth, Gps & packet data off, Wifi on.
I have to hold the power button down for prox 30 sec and ot starts up and goes through normal boot up. I dont know whats causing this either.
On this device, what does "Off" mean? If you press the power switch, does it really turn off,
or is it suspended?
I.E., does it go through a boot process when you turn it on, or does the screen just come on?
This looks like the sleep of death also happening with the Tab7.7 as well as on the Galaxy Note.
What does off mean

From the manual:
To turn on your device, press and hold the Power key. If you
turn on your device for the first time, follow the on-screen
instructions to set up your device.
To turn off your device, press and hold the Power key and
select Power off → OK.
It goes through the boot sequence.
I bought this tab 2 weeks ago and it's happened about 4 or 5 times now. Basically I'll put it in sleep or standby or whatever you would like to call it. Then when I go to press the Power button again I'll find that the screen won't turn back on and I'll have to hold it and turn it back on as if it were off. This whole turning off automatically thing isn't as bad as it was on the Toshiba Thrive I had but still, it shouldn't be there. Especially for a what I suppose is a premium product like this, I mean around $500 AU isn't just a little bit of money.
Sorry if I sound kind of negative but I hope this gets patched or something, Toshiba took a good 3 months to patch the Thrive along with upgrading it to 3.1, lets hope the 7.7 doesn't take that long.
One of the main reasons I got this was that I trusted Samsung for support, not just for ICS but for updates and customer support as well.
Try replacing the launcher. TW sucks big time.

I was thinking I'm the only one had this problem.
The device looks dead/unresponsive instead of turned off. I've to hold the power button for 15 sec or longer to force reboot.
Another thing I've found is 7.7 seems to work well without SIM card installed, no such issue happened for days, but it happens much more frequently with SIM card inside, i.e. twice a day.
I assumed this may relate to 3G module/driver/baseband/etc, until now someone said it also happened on P6810.
Could it be a software or hardward glitch?
looks like sleep of death similar to 7+, also exynos.

I'm pretty sure it's a software glitch. In the Toshiba Thrive, it could be patched. They don't sell the 3G variant here in Aus so I wouldn't know if 3G affected the frequency of it lol.
I have had atleast two shutdowns aday but since I added an everyday alarm(silent one), I haven't had none and that's 6days with out.
I know this sounds strange but works for me.

I've had it happen once to me so far, about 24hrs after purchase since then it didnt occur again.
using my data only sim card, which was pretty old and worn out, it happened to me a couple of times
now im currently using my newly replaced sim card, never experienced a random reboot again

I've had my primary worn out simcard on my tab for a few days and no SOD yet, when it happened the first time there was also no simcard on it, Im sure this is the very same issue with the Note.
same for me on GTP6810
this is SOD as I got on my Nook Color with cyanogenmod ROM ...
after I installed ADW Launcher Ex no more SOD ... not sure is related to the launcher ... I'll edit this post if I get SOD with ADW
EDIT: just got SOD
have you guys tried to turn off wifi when the tab goes into sleep mode in the settings?
My sim card not detected im only able to used it for several hour. And the last attempt after restarting for several time the device able to detected it but for only 10-15 minutes then sim card removed notification appear while the sim card is still in there. This really piss me off.bcoz i just bought this device.

[Q] Problems registering with network [SOLVED]

I have been having problems with my phone recently. I was previously running stock 2.1 rooted on Wind mobile. It had been working fine since I bought it in Dec 2010.
I seem to recall leaving my phone unplugged for a short amount of time (like a couple hours) and then when I picked it up the battery had been completely drained (while idle). I plugged it in and started it up after a bit and the battery was suddenly running super hot, and it would reboot quickly after starting. The only time it stayed on long enough to check the temperature I saw 57c. I left it to charge and came back and the battery temperature seemed to be normal again.
However now since then I have been having a lot of trouble registering to the Wind network. Half the time it is showing as roaming, or cannot connect at all. Sometimes, like as I am typing this, it will show that I am connected to the home zone. I can make calls now, but I cannot receive any. I have flashed the phone to CM7.2, and initially the phone worked but the next day it started having the registration problem again.
I tried the SIM card on another phone and it worked. Anyone have any suggestions?
Or you got fryed your phone module.. or fryed sim card.
First of all i'll recommend to replace or try another sim.
Just a little update...
It seems to have been working better in the past week, I could connect properly 90% of the time, but couldn't sent any text messages.
I went to replace my SIM card at the store, they gave me a new one and now it seems to be working 100% fine. So I guess the sim card was the problem.
Something to note is that the sim card was the original one I got when I signed up, and my permanent normal number wasn't on the card, only the temporary one assigned to me for the first day. So that may have been causing the problems I started having.

Noticed a bug in latest cyanogen nightly release cm-7-20130301-NIGHTLY-p999.zip

Maybe there will be no more cyanogen releases for this phone but I noticed a strange thing with cm-7-20130301-NIGHTLY-p999.zip a few weeks ago when I traveled outside of the US and had to put my phone in airplane mode to not get charged for receiving international roaming texts. Anyway, while in airplane mode, the battery level stays unchanged during the day of use on wifi. I have also experienced a lot more lockups while plugged in to charge in this mode. Phone seemed to freeze up over night while plugged in to charge and was warm in the morning with no display or response from buttons. Had to pull battery to get phone to come back to normal. This happened many nights in a row and when not in airplane mode the phone only seemed to lock up once in a few weeks. I can live with infrequent lockups but every night is a bit much. Can anyone duplicate this?
Flaming hot bsod is pretty common bug with this phone. Turn on stay awake while charging under Dev options and maybe that will work.

As an alternative to airplane mode.....Just remove all system apps that use the radio. Make copies of them and move them to your SD card and when you're back in the states push them back to /system with a root privileged file browser.

Had this issue myself, although it has been a few months. I will try Twitchys suggestion.

I been using Twitchyeye's suggestion for a few days and seems to work. Removing system apps seems a bit dangerous to me but thanks for the reply.

Pixel 3 "shutdown" problem

Picked up my phone off the charger today (1 week old 128g pixel 3) and it just shutdown. Almost like the battery died, but it was 100%.
Turned the phone back on, booted "normal", ran about 30 - 60 seconds and shut off again!
Turned on a 2nd time, actually started ringing immediately after boot, was able to complete a full phone call then it shut down after the call was completed.
Turned on a 3rd time, made a phone call - same behavior, lasted for the whole call then shutdown.
Tired safe mode - same thing.
Went to bootloader - seems to stay alive for a long time (~1 hour) - thinking it's not hardware... tried factory reset. Reboot phone and it makes it 30-60 seconds and shuts down!
Anyone else seeing MAJOR hardware issue like this?
Same problem for myself. Started yesterday morning. Phone was just went dead after using it a couple of minutes. Called Google Fi support and getting a new phone. Phone was dead to the world. The PC would not recognize the phone when plugged in. After the phone sat for several hours I got it to power on. Started that bootloop thing so I tried restoring using twrp. The was a no-go. Then reflashed the stock image (with out the -w). No go as well. Unfortunately the phone went dead again before I could just overwrite the phone. Going to try again this morning if the phone powers on again. If not back to Google.
[UPDATE] Nuked the phone(flash-all with -w), and reloaded the Nov. firmware. So far so good. Currently going through (slowly since my WiFi is slow as molasses) the updates and restore now.

Software update killed mobile network.

So my mother has a samsung s8 Plus and a software update was pushed through the other day. After it updated, the 4g/Lte icon on status bar is gone and now only has the no mobile network icon.
no calls/texts in or out. Took it to att store and they reset mobile network settings, did a factory reset, and replaced the SIM card. none of that worked. She then took it to a UbreakIfix(?) samsung
authorized repair shop and they tried the same things to no avail. Any thoughts or ideas from here?
Edit: forgot to mention that the airplane mode in the notification bar drop down is lit up light blue but is not turned on. it is light blue not the normal dark blue like all the other icons. very weird.
I am having the EXACT same issue. I don't remember when the last update came through, but it was Feb 16th when this started happening to me. I was moving to a new apartment, phone battery down to like 10%, so I turned the phone off and put it away. A few hours later I turned it back on and no cell connection. No bars, just a circle with line through it. Settings > About Phone > Status > SIM card status = shows Network "unknown", Mobile network type "unknown", Service state " Radio off", Mobile network state "Disconnected".
My SIM works in a Nexus 6 and Galaxy Note 4, so I know it isn't the SIM card. I've tried everything I can think of to turn the radio back on, replaced the SIM tray (original is cracked), even got a Freedompop SIM just to test, and yeah, it won't work. The cellular radio isn't turning on for some reason.
I will say, a couple days after it happen, I turned the phone on without SIM tray, and I could see empty bars, like it was trying to work. I turned it off, put my SIM in, and it worked... until my replacement SIM tray came in. Turned it off, replaced SIM tray, and it is off again.. for last 2 days. I just happened to turn it on that day and it was working, turned it off some days later and it stopped again. I don't know why.. no apparent reason. So, last couple days I have been turning it on and off, on and off, hoping it comes back on.
If ANYONE comes up with ANY ideas, please let us know!!!
Aaaaaaand... I turned it on this morning and the signal bars were back. I didn't even turn the phone off, I slid my SIM card, in tray, in to the phone, and it is working. I'm scared to even reboot it now, but SOOOO happy I don't have to use my Note 4 with dying battery right now

Thats funny because I had my moms phone just sitting in my nightstand drawer and she decided she wanted it back. So I gave her the phone back and she charged it up and turned it on. Guess what...it was working again. Very weird.

Tell her not to shut it down. That caused my issues the second time (well, the first time too). Rebooting, not sure... but I am keeping it charged and NOT shutting down until the next software update, for sure.
FYI... my charge cable got pulled out of my phone last night and my phone died in the middle of the night. I woke up, noticed it, and started charging to around 25%, turned it on, and now... no mobile signal again. Worked fine for I guess a month. A month of NEVER rebooting it or shutting it off. Once I did this it has now lost signal. Luckily I have a Note 9 coming Monday (tomorrow), but this is really pissing me off.
