So far this phone has been my worst HTC phone in 5+ years.

I'm getting random reboots when in no-signal areas, as well as random FC's in apps afterwards requiring the phone to be rebooted to work well.

It also chews through battery like crazy when it has no signal, and gets far worse reception than my HD2. My normal morning drive, while on a conf call, I go through multiple tunnels, and never dropped a call before. The G2? Every tunnel.

Also, my bluetooth is having call quality issues now, and I've tried a few different headsets. The fix? Reboot.

I think this ends my time with this phone, it's going back. Here I'd almost talked myself into being okay with no rooting, but that was before the phone started behaving like crap. If I want Android, I'll run it on my HD2 where it is stable. :mad:

EDIT:

I've also had the sleep of death happen even after a factory reset with no apps loaded. For a high end phone, this is utter crap.
[G2 and Desire Z General] grahammyhre:
I work in a lab where I don't have service and my phone was sitting on my desk restarting itself multiple times per day last week. I exchanged for a different G2 this weekend and my new phone did the same thing today.

Kinda concerned about the phone now. Sadly I already sold my N1, so I don't have anything to switch to.
[G2 and Desire Z General] nighthawk626:
****taaaaaaaay. my g2 doesnt have any prob. the hing thing i can live with but no reboots or any problems. dont go around bashing all the g2's out there because im sure of alot of people that dont have the problem.
[G2 and Desire Z General] borodin1:
Don't kid yourself, it's just a matter of time...
[G2 and Desire Z General] arthurbrownleeiv:
Yeah, judging by how many at the TMOUS forum are freaking out about this, and now talk on XDA, unless they get a fix on this quick, this will be a flub of a phone at this price point.
[G2 and Desire Z General] nighthawk626:
nah, just lik the hinge problem where all of em wasnt having that problem, not all g2's will have all the above problems mentioned. besides im using this phone heavily with every app n all (my way of testing endurance) so far pretty damn good :D
[G2 and Desire Z General] n3rdftw:
just another confirmation of reboots at random times

and sometimes the phone continues to work, but the screen just goes blank until i pull the battery
[G2 and Desire Z General] arthurbrownleeiv:
At a client site today in the server room, and it rebooted while I used it 4 times... So much for being able to do SSH tunnels over the wifi with it.

Back to the HD2.
[G2 and Desire Z General] borodin1:
Manufacturing is mechanical process so some differences are expected. Radio is the same in all phones so reboots are inevitable. Just wait for the right condition (i.e. bad reception area)

[G2 and Desire Z General] tenbeau:
I had my G2 turn itself off. Came out of the mall and I had the Black screen and after hitting the power button to what I thought was to unlock the screen nothing happened. All the way home I continued to push the power button and hold it in for different periods of time with No success. After arriving home I pulled the battery and hit power button and it now works. I have no idea what this is about or what might have caused it except perhaps it lost signal in the mall and then exhibited the behavior being discussed in this thread. I am beginning to believe that this phone has wide spread problems as this one has other issues and is the second one I have tried with another on the way here. It will arrive tomorrow. I am seriously considering just sending it right back and getting a refund. I do like the phone but this issue is ridiculous for a Phone of this stature.
[G2 and Desire Z General] fryrice8850:
im just waiting for a confirmation email back from tmo cause i am an employee so i have to go through the process of shipping it back to them and then they have to test it and then i get a replacement. so i'll let u guys know in about a week if the new one will do it.

the problem is it is totally random.
[G2 and Desire Z General] hellbringer626:
This happened to me as well battery pull worked. i was a little bit freaked out because I'm having so many issues with the phone.
[G2 and Desire Z General] Tripod87:
Happened to me about an hour ago for the first time as well. First issue I've had with the phone so far (other than loose hinge that doesn't really bother me).

edit: Just happened again :(
[G2 and Desire Z General] tenbeau:
Has not happened to me since this afternoon. Were you in a low signal area when it happened? I also have noticed that when the keyboard is deployed the return key does not work well and sometimes the touch keys do not function at all. Any one else notice this issue? Also when deploying the keyboard apps will start in a random fashion. I checked to make sure I had not touched the screen and I had not. This has happened several times but not every time. Also upon applying the gel skin and hard case from T Mobile store the phone just wants to slide open with the slightest pressure. It will slide out when just picking it up from a table. This is worrisome to me as I want to protect the phone as much as possible and am now concerned about the hinges lasting any length of time.
[G2 and Desire Z General] Tripod87:
Yeah, low signal at work, happened twice today, but zero times yesterday. And I work in a cube too so I do spend at least 70% of my work day in the same area. Weird.
[G2 and Desire Z General] CoolCriSyS:
I have been having similar issues with my G2. As far as I can tell, it's whenever I leave my T-mo coverage area and enter the roaming state (AT&T coverage). My phone will lock up and reboot randomly along with other slow and odd behavior. Sometimes I even need to pull the battery. Once I get back to my coverage area, the phone works flawlessly again.

I am hoping that this supposed OTA update that has a radio update will fix this issue because this is a deal breaker for me with this phone as I travel to that roaming area a lot.
[G2 and Desire Z General] magicducksauce:
2 days ago I turned off the back up data & automatic reset in privacy settings as per a suggestion earlier and have not had any restart issues since then (I had 3 before then).
[G2 and Desire Z General] fryrice8850:
So all these reboots seem to be having to do with poor coverage
[G2 and Desire Z General] crawfordmd:
On #2 and it still reboots randomly

Hey guys,

I was one of the lucky ones who pre-ordered the G2 and received it on Oct 2nd. My first one had a lot of random reboot issues, locking up, memory card write capability, and bluetooth pairing.

Sent it back within my 14 day period for a replacement. Received the 2nd yesterday and the phone is constantly rebooting itself. Regardless of coverage area...has happened in dead zones and 4 bar areas.

It doesn't recognize my bluetooth earpiece either. At this point I am pretty disappointed. I will try the workarounds previously mentioned and let y'all know my results.

If anyone has heard anything from T-Mobile, I am all ears :-)
[G2 and Desire Z General] fryrice8850:
u serious? damn...well my g2 hasn't been restarting because i leave it on airplane mode while im at work because of no service in the building i am in.
[G2 and Desire Z General] crawfordmd:
Yep....I noticed the same thing as you...was in Jamaica last week and left the phone in "airplane mode" all week with no reboots.
[G2 and Desire Z General] crawfordmd:
Tried the workaround mentioned (disabling backup restore...) from the Tmo thread and still seeing reboots.

Called Tmobile tech support and they said they know about the issue and are working it.

My problem with it is as much as my phone is rebooting (almost any time I use an app) it makes my phone unusable. Kicker is I can't return the second phone under the buyers remorse policy since it is more than 14 days since I received my first phone. :mad:

Hope they come up with a fix or the devs get a perm root soon.
[G2 and Desire Z General] stevencpoynter:
I posted something on another thread that has seemed to work for me so far(too many threads! Maybe i'll start PMing?)

I was having fc issues and reboots during high and low signal areas, I ran fix permissions on Rom Manager and ~95% of my personal issues have been fixed.
[G2 and Desire Z General] mdayjr:
Mine started rebooting @ abt the 26th or 27tg hr.I think I got it figured out y it does. The ram gets depleted and then it reboots. Oddly enough I've had 2 times so far giving me the no software screen.
[G2 and Desire Z General] rdsport323:
It happens quite often whenever I am in an area and lose signal for around 15 minutes... like in a basement somewhere or deep in a building.

If someone sends me a text message during the 15 minutes I have no service... as soon as I get service, the text message will appear for a brief second followed quickly by a a reboot/G2 logo screen.

almost positive it will happen every time.
[G2 and Desire Z General] phazedplasma:
I've notice reboots in low signal areas as well.

I was at work in a decent signal are for 7 hours yesterday and not a signal reboot, but at home where I have terrible signal (in NYC wtf...) I've had it reboot twice so far (had the phone for 3 days).

Also I've had the phone show up with a black screen with the picture of a phone and a red triangle/exclamation point, does anyone know what this means?I took the battery out and it booted up again, but that makes me nervous...
[G2 and Desire Z General] cam_hamlin:
mine was also rebooting randomly...i factory reset the phone and it hasnt done it since....
[G2 and Desire Z General] mikeatron:
didnt even know this problem existed, mine has never rebooted on me
[G2 and Desire Z General] Forrest80:
Mine has rebooted 3 times with in 3 days. First time in my house, it rebooted and some how i ended up roaming on ATT's network. Second and Third time i drove through dead spots and ended up R on my signal for roaming, no idea whos network i was on.
[G2 and Desire Z General] Arcadia310:
I haven't experienced this issue until two days ago. I took my phone out of my pocket and noticed it was off, very odd. Then later on I was using it and it turned itself off and rebooted. It only happened twice, wonder what caused it.
[G2 and Desire Z General] vikramdhani:
I will be returning my G2 and see if the new one will have the random reboots issue.
[G2 and Desire Z General] Bloodbeard:
Seems to happen most often for me when browsing websites with Flash content.

I think I've only had 1 FC, but about half a dozen reboots or more. Maybe the error handling routines are inept enough that crashes cause a kernel panic.
[G2 and Desire Z General] Forrest80:
More update. I was not roaming and i had good signal. I was playing Angry birds and it wasnt playing right so i closed it, turned on wi fi. Tried Angry birds again. Turned off Wi fi. Turned on Wi Fi again. Tryed angry birds again and it did the reboot. Its not a full reboot where you see the HTC logo. It was just "soft reboot". The uptime stays the same. Angry birds was not playing properly no matter what and at the end WiFi had a error also and boom it went for the boot.

Reason why i kept turning wi fi on and off is becuase i remember last time playing with angry birds and wifi got me a reboot and it did this time too.
[G2 and Desire Z General] phazedplasma:
I talked to tmobile about this, they to me to do a reset (wipe) and I did, so far so good, but i'll give it a few days.
[G2 and Desire Z General] Authority:
Has anyone had an issue where the phone just shuts down? Mine has done this about 3 times after it has been on for over 5+ hours it just turns off... Doesn't restart.

Sometimes I can hold the power button and it turns back on starting at the HTC screen, other times I have to take out the battery and then power it back on.

Does anyone know what would cause this? Or how to fix it? Should I exchange my phone?

Thanks!
[G2 and Desire Z General] Tripod87:
Just to let everyone know, I called Tmobile's cancellation line and the rep said he never heard of this problem and sounded surprised (and usually, these guys are the closer to the brighter and nicer bunch of anyone you talk to in Tmobile). He instantly told me to return it since I'm still within 14 days. Just seems weird that some reps know about this issue and others don't...
[G2 and Desire Z General] CoolCriSyS:
To go along with what I said before about the phone rebooting when I enter roaming, if I turn of data while roaming it at least stops that odd behavior of locking up and rebooting. So it definitely has something to do with the data coverage that makes the phone struggle like that. At least for me.
[G2 and Desire Z General] [hfm]:
Yesterday I had my second instance since I bought it on the 6th of my phone locking up then sitting at the G2 logo screen. When it came back I had lost Angry Birds install and also my wallpaper. I decided to just do a factory reset. Lets see if that fixes it.
[G2 and Desire Z General] zuludelta9:
People say it doesn't fix it so I haven't bothered. Hopefully you'll have better luck with it
[G2 and Desire Z General] jjerdmann:
This seems damn close to 100% accurate of the same problem I've been having.
[G2 and Desire Z General] robothouse:
You might have noticed I posted on this issue a while back. I've received a replacement phone and wanted to give an update...

After using my first G2 replacement for almost 2 weeks now, I haven't had a reboot issue rear it's ugly head again yet. I keep my SIM card locked, so I would definitely know if the phone rebooted on me. I have tried to replicate my reboot scenarios (going out of tower range, going between 2 low signal towers, using myTracks in the mountains out of tower range, etc.) and have not experienced ANY reboots on the new device yet. Heck, I've even dropped the phone in water, which fried the SIM card a week ago, and got a replacement SIM and everything works like a dream! I suppose I got lucky based on other posts in this forum.

Of course I might not have been sent a txt or vm while in an outage area...
[G2 and Desire Z General] rccolburn:
I had this problem. I fixed mine by reseating the battery and sliding it back and fort as I pushed it toward the contacts.

Has not rebooted since. 5 days now. Was happening several tims a day.
[G2 and Desire Z General] dronepop:
I don't believe wiggling the battery will solve these widely reported problems, this is just a coincidence that yours seems to be working.

Also, the only way to know definitively that your phone has rebooted is if you have a sim lock on or something else that keeps the phone from loading the home screen automatically. Even if you look at the "on" time for the phone after one of these unwanted reboots, it will show that the phone has been powered, with no resetting of the "on" time.

So, my question to anyone saying they have "fixed" the problem by replacing a SIM card or reseating the battery (neither of which will work) how do you know the phone has not been rebooting on its own?
[G2 and Desire Z General] rccolburn:
I have VISIONary installed without the auto root on reboot. As long as I haves root I know there was no reboot. May be a coincedence but easy to try.
[G2 and Desire Z General] Crey23:
Welll.....actually I have had a reduced number of reboots since I went Visionary. Acutally It was when I OC to 1.42 MHz that the reboots stropped.

Here is my take...my office ver poor signal...widely ranges from G to E to H up and down all day....at work is were I have most of my reboots....while I am at home or our and about, hardly any. With that said I Temp Rooted my phone last week, and still had a few reboots at the office. I OC'd it on Saturday night, and all day Sunday it worked flawlessly!!!!

It wasn't until this morning, back at the office, that I started having issues again. This could be that installed the Beautiful Widget (Sense like clock and weather) and a free, live wallpaper that made the the Sense weather experience come to live. I can honestly say that I have had all the issues this morning since I downloaded the LWP. I have since removed it and I have had only 1 reboot.

I think there are a combination of things at play here, but I do think that signal variability (violent swings) has something to do with it.
[G2 and Desire Z General] enjoijams:
microsd?

My girlfriend's G2 is also having this same issue.

So we took it back.

Now she's having the same problem with her new one.

As a bit of troubleshooting I took out her microsd card for 3 days.

Problem dissapeared!

We bought a new microsd card (16gb!).

Problem came back.

Will any of you having this problem with the rebooting, try this?

See if the problem dissapears on your G2 without the microsd.

Tell us how long you go without it rebooting.
[G2 and Desire Z General] Gr8gorilla:
My college is in a low signal area for T-Mobile. I can get 1 Bar H if I am lucky and 2 or 3 Bars of E other times. Indoors it is much worse. When I am at school, walking around campus I get constant reboots. Just about anytime I look at the phone it is on G2 screen or it is locked up.

At work I never ever have this problem. I keep a full signal and get no reboots.

I wonder if it is similar to the low signal reboots the Incredible was having?
[G2 and Desire Z General] tankmorph:
I also just got a replacement G2 from UPS this morning. Hopefully to address my random reboot issue and random signal flakiness. I started a new thread discussing differences in part numbers, too. Check it out when you get a chance.
[G2 and Desire Z General] bonkasnucca:
ill do u one better

well i have been having the random reboot just like evrybody else..but just the other day it rebooted randomly and wen it cam back on i was at the initial setup screen..my phone randomly did a factoy reset and i lost evrything...super pissed and starting to get fed up with a phone i thought i wud love
[G2 and Desire Z General] jmd1981:
I started having the reboots recently. Just wanted to chime in as I'm not in the country and I have my service suspended for that reason. So, my thought that it isn't entirely service related although I'm sure that could be a factor. Its not that annoying, but if it keeps up I'm going to return it when I get back to the states.
[G2 and Desire Z General] rickrugz:
Same here,where signal is lost my device it does reboot and with the new youtube update as well does stick where I have to pull the batt...Can't wait for perm root
[G2 and Desire Z General] jmd1981:
WTF, so I called T-mo and the recommended that I format the SD card and factory reset. So, I did and now it's rebooting even more. This thread wouldn't exist if there was a fix, but is the only way sending it back? I'm in Japan and it will be a monster pain in the ass... so done with this phone....
[G2 and Desire Z General] drizzle123:
My phone randomly reboots almost every single day. What a joke. The nexus one was and is the best phone of all time.
[G2 and Desire Z General] Forrest80:
Was testing with my friends G2. She does not have as many reboots as i get due to her area is better signal strength. She brought her G2 over to my house. I was playing with my g2 and it started to reboot, I then picked up her G2 and started to play with it and it started to reboot also. Maybe less than 1 minute apart i got both to reboot.

So pretty much its a area thing.
[G2 and Desire Z General] jmd1981:
Hmm, I don't even have service as it's shut off and I get the reboots. Are we sure this is a coverage thing? I'm not connected to any network at all.
[G2 and Desire Z General] fryrice8850:
yes tmo is working on the issue...it is due to no service the phone will lock up or reboot itself. seems it is the samething that the droid incrediable was having. just waiting for tmo and htc for a update

just put ur phone into airplane mode and no more reboot. (in area with no service)
[G2 and Desire Z General] cam_hamlin:
Ever since the OTA mine hasn't rebooted once and its been a few days....it used to always reboot when I was in a low signal area and I worked in a building where there was little to no signal so of course it would constantly reboot...but no more since I received that OTA....
[G2 and Desire Z General] robothouse:
I'm about to get my 4th G2 replacement... and am still getting the random reboot issue... ugh! methinks I'm going to try to get T-Mobile to gimmie a Nexus S as a replacement. BOO to HTC BOO to T-Mobile.
[G2 and Desire Z General] zuludelta9:
Yeah, I haven't seen the reboot either since the OTA..
[G2 and Desire Z General] oldsk00lz:
That's unfortunate. I wonder if you have a bad app that is hosing the system? I know that I was having issues with my G1 running a Froyo variant and rebooting randomly at one point, so it might be an Android thing.

I have hardly had any random reboots on my G2, though.

You may want to try rooting your phone and giving the CyanogenMod 6.1 ROM a shot. I know they have done a lot of improvements that may help resolve your issue.

-oldsk00lz
[G2 and Desire Z General] fryrice8850:
i believe T-Mobile will not sell the nexus s directly...you can't even add insurance on the phone. Just like the nexus one tmobile will not be selling it.

i work for tmobile and we have not heard anything about receiving shippments for the nexus s
[G2 and Desire Z General] zielin:
I've had to send my phone in a couple times because of it deciding to shut off on its own too. I actually spoke with a customer loyalty rep tonight as I had the same idea... she says tmobile will not be selling the nexus s.
[G2 and Desire Z General] AreOh:
I had 2 reboots today for the first time. I don't like this at all.
[G2 and Desire Z General] Sh0rty007:
Same problem here.

It started the first week i got my desire z. First day, i was checking my phone and suprisely it was turned off.

Few weeks after i got my phone i set CM 6 on it, no problems with just turned off itself or randomly reboot itself.

This day, i turned back to my nandroid backup from stock, three reboots in one day...

So now i'm back on cyanogenmod and the last few hours i had no reboots at all...

So they better came on soon with the gingerbread update for the G2/desire z and solve this problem everyone seems to have now with sense...
[G2 and Desire Z General] robothouse:
welp... after dealing with reboots on my 4th g2 replacement, I've given up.

Combined with the hardware/software reboot issues on the device & recent issues with the device hopping from H -> G -> E for about a minute every time I received a call, missing calls, etc. I've ditched t-mobile and gone with EVO Shift 4G on Sprint... which ultimately has a better network in our area.

Thanks to all over here for the insight and suggestions... :)
[G2 and Desire Z General] fryrice8850:
^ yea i have switched back to my blackberry 9700 its not really the service more like the phone.
[G2 and Desire Z General] oldsk00lz:
For those having issues, did you ever try to run a custom Rom like CyanogenMod? I know the community has been fixing lot's of bugs, adding features, using the latest AOSP, and improving performance. Even have a gingerbread release out.

I'd suggest others to root your phone and give it a shot if the stock Rom is not being nice with you. There are also some updated radios that work for the G2, but I have not tried those.

-oldsk00lz
[Android Software/Hacking General [Developers Only]] mschlott:
I have an otherwise stock EVO that I need to remove a file from /data.

Can I do this using adb?

It looks like I need root access to do this?

mount gives "operation not permitted" error. Is this a major undertaking or can I just install a simple package to get me access to this folder?
