Official HTC EVO Random Reboot Thread

From searching, it looks like tons of people are having random reboot issues with the HTC EVO. Let's make one thread to put everything so maybe we can figure this out.
Side note, it looks like the HTC desire has the same issue:
http://forum.xda-developers.com/showthread.php?t=676402&highlight=rebooting
So post what you've tried that hasn't worked.
If you think you have a solution, share

One thing I've noticed is it seems heat related.
I've installed temperatures monitors and it seems around 32 degrees Celcius is around when it reboots. It will reboot loop usually. This can be cured by pulling the battery and waiting for it to cool down, or just put it in the freezer for 4-5 minutes.
I've tried underclocking it with the screen dimmed way down, and running it without the back cover and it still overheats.
For me, the problem came out of nowhere. I had the device for over a month with heavy usage and no problems. My current GUESS is it must be a physical problem. Not enough thermal grease or something...
It looks like the HTC Desire users may be getting replacement motherboards to fix their issue.
Does the HTC EVO and Desire share parts?
From other threads it looks like:
Root or Stock - Doesn't matter
Radio version - Doesn't matter
Rom version - Doesn't matter
GPS Fix - Doesn't matter
GPS turned off - Doesn't matter
3G data, 4G data turned off - Doesn't matter
Hard Reset - Doesn't matter

Found this on the HTC Desire reboot thread:
Latest test list for HTC Desire RR (Random Reboot) problems:
-All phones with s/n HT03 to HT07 can get this problem (Minor problem from SH09 so far)
-Starts around 1.5 to 3 months after use
-Reboots get worse over time
-Firmware and android version doesn’t matter which you have
-Force apps2sd doesn’t matter if you use it or not
-PVT1 or PVT3 or whatever doesn’t matter
-Screen type, doesn't matter if you have AMOLED or SLCD
-There seems to be an antenna/radio/simcard issue also
-Overheating causes reboots too
-Reboot is not always temp related
-SD card size doesn’t seem to matter
-Having apps on SD or not doesn’t matter
-Size of files on SD doesn’t matter
-Rooted or not doesn’t matter
-Motherboard changed after repair doesn't always fix it
-Sim locked or not doesn't matter
-Provider doesn't matter(vodafone, kpn/hi, T-mobile etc all got it)
-Most likely hardware issue, sense flashing won’t fix it, yet changing motherboard will
-Restarting doesn't fix it
-Factory resetting doesn't fix it
-Changing/buying new battery Doesn’t fix it
-Using app killers or shutting down some services yourself doesn't help
-Leaving all settings on default doesn't fix it
-Plugged into car charger in the past doesn’t matter
-Hboot version probably doesn't matter (still not fully tested)
-Having a phone cover or not doesn’t matter

wifes phone has been doing it very bad...one that has never been rooted...
was going to root it and try new rom but seems to be a hardware issue.
any other comments on this subject?

My stock rooted Rom just rebooted for the first time today. I really don't rememebr what I was doing st the time....but this has never happened before. I assume there's no event log to check.

I had been facing this with increasing frequency. I got the phone on launch day, and the problem started over the last month, getting worse all the time. I agree with the OP that there does not seem to be any obvious cause -- sometimes it is heat related, sometimes not. Any time I push the phone (run psx4droid, or navigation + anything else), and sometimes even with lighter usage, like on a phone call. Unrooting did nothing to stop the problem.
After extensive searching, I found three possible causes: bad battery (I tried a new one and the problem continued, but this seems a good starting place), bad memory blocks, or bad processor.
I was unable to find any solution to this problem. I took my phone to Sprint today, and they told me that their tests didn't show a problem. Then I made it happen in front of them (launch navigation to anywhere, then a couple more apps, then boom, reboot) a couple times (really, after the first time, letting it turn back on pretty much caused it to happen again).
After that, they agreed to replace it. I do have the TEP, but they assumed that the problem was hardware related so I don't know if you have to have it for them to replace it.
Strangely, they gave me a white one as a replacement.
I haven't had any problems with the new (well, re-manufactured) one, and I hope it stays that way, but I guess only time will tell.

I'm currently experiencing the problem as well, funny thing is every time it happens, the phone is NOT in use, simply sitting on table or desktop in standby. This happens about once every two days.
Currently running rooted evio2 1.3.1

Wow, I was about to start this thread, when I saw this. I guess I was like 10 minutes late. Either way, i believe something messed with the hardware. My little bro cracked my screen badly, so I am getting a new evo anyway, but will I be able to get one free bcuz of this? This is really a terrible problem. Somebody needs to de-assemble their precious evo and see if there is an obvious problem. thanks a bunch. Subscribing.

same here.
happens mostly when on the charger and i am using it at the same time. so heat related seems likely.

can anyone get a logcat of it happening?

I called sprint support and they said it's defective to return it.
Taking it in for replacement today.

Sprint replaced mine for $35 [a refurb]. That's the end of that.
But now, I can only use the speaker to hear my callers. Gotta go back and get another!

My guess is the new update could be putting a lot of strain on the battery but who knows? I haven't experienced it but maybe its because I'm using the extended mah 3500 seido battery.

No, I've got the 3500mAh Seido battery too.
I don't think it's strain since mine has gotten worse. AKA the amount of usage it take to make the phone reboot has gone from hours of use to minutes.

Actually I just had a reboot lol.

Same thing here. I posted my issue in the rom threads i used, and everyone ignored the issue, lol.
For me, I noticed it about a week after using roms with the new software update (3.29). It happened with navigation, launching multiple apps, running quadrant, etc.
So yesterday I installed DC 3.5 from scratch, turned nav on and let it sit for a couple of hours. NO reboots. Before, after 10 mins of the screen and nav being on, I'd get a reboot. Has anyone else tried this (or willingly to try it)? I switched back to my nand backup, ran quadrant -> bam, reboot.

I bought my EVO on launch day (HW Version 002), and have not had any problems until around Oct 13.
I took the phone on a trip to Orlando, and as soon as I got off the plane and turned on the phone, the problems started happening. It has been happening ever since, even since I returned home.
I bought my phone at Best Buy, and have had their Geek Squad send it back to try to fix it. I also added the complaints about screen separation to the workorder so that they would be more likely to replace the device. Hopefully, this fixes the issue.
I also think it is heat related, but I don't know why it is just now becoming an issue. Just to make sure the folks at BB could see the issue happening, I put the phone in front of my car's heater for a few minutes, then started up Google Earth, and was able to make the phone start boot looping while I walked into the store.
I tried hard reset, soft reset, update prl, underclocking, GPS Reset, new battery, new SD Card, and none of those things worked. I wonder if the removal of the 30 fps limit in the last update caused some type of heat damage?

I just had a reboot last night while trying to look at a picture I'd just taken in the Camera app on CM6.0.0. Only the 2nd or 3rd time it's happened. Still annoying though. Hope it doesn't get worse.

I reset mine back to stock. Unrooted it and everything.
Didn't fix the issue for me.
Now I did try erasing all the stuff that's erasable inside recovery and it seemed to go a few days without a reboot. Not sure if that was a fluke or not.

[Q] Major problem with my stock ATT E980

Okay, I originally got this phone as an upgrade over my HTC Inspire in July. It worked great, minus a few random reboots every once in a while (if I left it in my pocket for a long time or if it was really hot in my car it would do this, but that was it). Then, about a month or two ago, I rooted it and installed a custom ROM. I noticed that a bunch of my files were missing from my internal SD card, but I wasn't too worried about it. Then my phone started acting really weird and got stuck in a bootloop. I was able to boot into recovery, but I ended up using the LG Flash Tool and went back to bone stock. Still had the issue, except I noticed that my signal would drop, and then it'd get stuck in the bootloop. So, I contacted AT&T warranty and they sent me a replacement. Now the same thing is happening to this one. It gets warm, loses cell signal, then reboots, sometimes a bootloop. This phone hasn't been rooted at all, it's been left stock. So I contacted AT&T and the guy in warranty said he thinks it's the battery, but he didn't have any in stock so he couldn't send a replacement. So I was thinking it was the battery and called LG after it seemed to get worse. They told me that they could replace the battery free of charge if I send in the one I'm using first. Since this is my only way of communication, I contacted AT&T again, and they're sending me another replacement. (Said if this one screw up too, they'll give me a different phone all together). The guy had me download some AT&T remote support app and he looked at the battery health and said it's reading fine, and that because it's reading fine, he didn't think it was the battery. :|
Here's the weird thing, about two weeks ago, it went into a bootloop. I took out the battery for a minute an tried to put it back in. Nothing. I plugged the charger into it and it basically told me that it didn't have enough juice to power on. (battery was at ~40%). So I took the battery back out and tried again. This time it came on.
Then last friday, I was jammin out to music while I was working, it would reboot when I unlocked the phone. (battery was in upper 90%'s). I plugged the charger in while it did this and everything came up as it should. But after taking it off the charger and trying to do more work, it happened again and again.
Like I said, this phone is straight from AT&T and has not had anything flashed onto it by me, hell I never even disabled all the AT&T bloat this time. I've tried a hard reset, and it didn't help. Does anybody know what would be the cause of my problems? I really like this phone and really hope I can get this figured out.
EDIT: Forgot to mention, the phone still has its IMEI number and it has the value pack update.

Got the second replacement in the mail today. It hasn't screwed up yet, but only time will tell.

Wow hope this works for you. I just got 3 Optimus G Pro's on 12/30/13 and all 3 of them to date have not had any issues. 2 black and 1 white. 2 which are running stock. 1 stock which has had a bunch of the bloatware yanked (that we could get off of it). 1 stock which has had nothing pulled, everything left the way it is. And the 3rd one (which is the one I use) which I rooted to CyanFox 4.4.2 and later to CM11 4.4.2 Nightly and haven't had any issues like the ones you've explained.
Good luck though hopefully your issue is gone. Seems like a nice reliable phone (minus LG not wanting to support it furthermore ).

I really hope my issues with this phone are done too, I really love this phone. If I don't have any issues, it's going to get rooted and updated to KitKat. Otherwise, I'll try to get AT&T to give me a MotoX or a HTC One.

Yeah I like this phone with KitKat. Looks like a larger Nexus 5
Only problems i'm having with CM11:
1. ATT Visual Voicemail will install but upon playing voicemails program will freeze and crash
2. Tried Google Voice however you can only hear the voicemails through speakerphone, headsets, or bluetooth. Voicemails will no play through earpiece.
3. CM11 doesn't have Screen Recorder yet (Which CyanFox did although CM11 is still fairly fresh).
4. I would like to have the LG Camera app back! Dual video recording and some of those other features are gone with the android stock Camera app. Need to look into porting that back over to KitKat (if I can).
That's bout it though...

Haha yeah, this phone is beautiful with stock Android, I just end up missing certain touches that LG puts in their overlay.
BTW, this phone is doing the same thing as before. I strongly believe it's the battery b/c when it went into a bootloop, I took out the battery it was warm, so I put it in front of the AC for a minute to cool it down and it's been working fine since. So, I'm going to call AT&T and see if they will send me a battery, and if they can't, I'm going to have to send this one in to LG and be without a phone for a week...:'(
UPDATE: AT&T told me "since we have tried everything else-hard resets, replacement phones- and nothing worked, we will send you a battery since it's the only thing that has stayed persistent through this ordeal. We just got some in stock and are sending one your way. If the problem continues to persist, we will replace the phone again." IT'S ABOUT TIME!!!

Just curious, but what if I continue having this issue after I get my new battery? Should I try a similar mah zero lemon battery or just have att give me a different phone altogether?

i think there is an issue with the battery and whatever cable you use to charge the phone.I had to Lge980 when I used a thin cable I have in my room sometimes it did not charged at all and or shut down itself even when the battery had half charge ,sometimes it showed full charged but if I plugged the phone to a thicker cable connected using the oem charger or a usb 3.0 port at my laptop it showed the real charge level at 1/4 charge.I myself could't do anything since I got the phone second hand but as long as I used thick cable connected to a oem charger usb 3.0 or eben 2.0 I had no had any issues.

how'd it go?

I've had the exact same problem with my E980 and the refurb they sent me. Contemplating a battery replacement now. Did a new battery fix your boot loops?

If you want to stay on stock i recommend going to jellybean TOT 10k and rooting and installing a custom recovery back up the rom, and flash hkfriends kernel, and see what happens if you raise or lower your phones voltage, that might be the problem with it rebooting.

THE NEW BATTERY SOLVED THE ISSUE, BUT ONLY FOR A SHORT TIME. I upgraded to an HTC One M8 since, and haven't had hardly any problems with it, aside from the death star's BS

Thanks for the response. I talked to the techs at an AT&T direct service center and they told me it's a common problem with the Optimus Pro. I'm on my third one in 8 months now and this one started randomly powering off within 15 minutes of when I took it out of the box three days ago.

Yeah. My issue was the battery for sure. Make them replace the battery and it should temp solve the issue

From what I read on the first e980 i had these phone tend to have a hardware problem where the power button is creating the same issues as OP. Some refurbished e980s have the hardware problem solved.

Boot Loop after one month

Here we go again...
Another LG phone having boot loops...
Bought from Best Buy on April 5TH with no protection...
May 6 phone started its random turn off....Have to do a battery pull and rest it for 10 minutes to get it to start up again..
After a min or two , it powers off again..
Yes, I was able to do soft and hard re-sets to no avail...
Just filed a repair request with LG...
Grrrrrrr

I had the same issue with Sprint LG G5. I bought it in April 13 the from Best Buy. It started to reboot 3 times at first and got real hot before it started rebooting. I took it to Sprint repair center where they suggested to do a factory reset. I told them I can do that. But before I was able to do a factory reset, it finally died. Sprint didn't want to replace the phone since I didn't have insurance. I might have to send it to LG for warranty repair which will take 9 business days. Do not buy the LG G5..

About a week and a half after I got my G5 it overheated really badly and turned itself off and wouldn't restart after attempting to reboot several times. I disconnected it from the power source let it cool off then plugged it in using the OEM power wart that came with the phone. That worked and the phone restarted. A week later the same happened. The phone overheated and attempted to restart several times and this time it seemed hotter than the first time. It turned itself off eventually and I was unable to turn it back on again. Less than three weeks into ownership and the phone was completely unresponsive and dead. I took it into the sprint dealership and they initially refused to replace the phone despite the fact it was under a month before this problem surfaced. They wanted to take the dead phone and have a new one shipped out to me. I told them that was unacceptable and they came up with the compromise that if I signed up for protection now they would backdate it and give me a new replacement phone. I took the deal with the full intention of canceling the protection plan within a month or two after I'm sure this new phone isn't going to be an issue. The new phone has been pretty solid for me so far. It gets warmer than I like but that may just be a product of hypersensitivity to heat after the first phone. That was the first time with any phone that I've ever had where a phone catastrophically failed on me like that. Sprint's response at the their shop was completely unacceptable given the time frame since purchase. I like the phone but I'm not liking how ownership of it is starting out. This was about two weeks ago now and I'm still gunshy with this phone afraid this new one is going to crash on me as well. I do not like that feeling. Thank God I have a backup phone just in case.

Goes to show phones these days are not built the same. I've had the g5 since day 1, not any of the problems I've read I've had since owning the phone. I got mine from a Sprint store also. Only issue I have is the slight lag I have when connecting to anything internet related. I believe that to be something kernel related.

how long did it take to get the phone repaired through LG?

Reboot ahhhhhhhhhhh
My G5 keeps doing a reboot cycle but only on one app (wwe supercard) how can this app cause this issue??

Marshmallow broke my phone so I...

Installed CyanogenMOD and it still resets, locks up and has other performance related issues.
I did an OTA update to Marshmallow originally. This corrupted my SD card and then caused about 10 resets a day, ranging from when I was using it lightly to heavily or even when it was sleeping/screen off. If I woke it up it would reset or I could feel it reset when it was in my pocket.
First thing I did was a factory reset. I tried other tricks such as swapping out the battery, SD card (or none at all), clearing cache, etc.... Nothing worked. So I tried installing CyanogenMOD, and I failed. But I got the phone back to BPA1. I updated back to marshmallow via my computer and the Verizon software updater.
About a day later the resets and lockups came back. I kept it light of apps but did slowly begin to reinstall some of my usuals (from the play store).
I had some more time so I tried installing Cyan again and was successful. It took a long time to load and optimize but it worked. I used gapps mini and the only step I did not follow in the guide was I did not install xposed.
It's been running for about 12 hours and has hanged, locked up and rebooted on me multiple times. Chrome even locks up (it will stop resounding, I'll get the message asking if I want to wait or close at the same time it starts responding again.)
When it reboots, it still takes forever and even optimizes apps (that I assume have already been optimized). I've seen two boot screens for it, one the little alien guy and the other with gears turning. It did the gears the second time I booted and then I haven't seen them again.
I'm not sure what my next step should be. Maybe I'll try reflashing Cyanogen. I have a feeling it's a hardware issue at this point, but I'm open to ideas. Are there any good diagnostic tools that could help my situation?
The phone is out of warranty and I'm sure that now that I've installed Cyanogen, the warranty was voided anyway. It's a shame because this phone was perfect up until the marshmallow update. I probably had 5 lockup/boots in the year or two I've had it.

Why are you using cyanogenmod in the first place. The support for that has ended. Go to the lineage os nougat thread and use that instead.

Admittedly, I did not even know about lineage until my phone was wiped with no OS. I did a quick Google search for it but could not find a Verizon note 4 mod. Now that I am not pressured to find a fix, I'll research it a bit more. Thank you.

I tried EmotionOS and NSeven, but both share the same error.
Emotion FCs random processes sporadically and then when my cell/data switches to Searching, it crashes multiple processes until the UI (trebuchet is default for Emotion?) and/or settings FCs and I have to restart. I am also stuck on 3G on that platform. I'm guessing network connectivity / switching is the root of the problems.
Nseven installed and right at the Welcome Screen where I pick my language, Google Play Services started crashing. I only had the option to click OK and then every 5 seconds after that, it kept crashing. I set up the phone, restarted and Google Play Services started crashing again. I am in the process of restoring back to Emotion, as it is the most stable platform so far.
I tried a new SIM card, hoping this was the problem but to no avail.
Does anyone have any other suggestions? I'm guessing its hardware at this point, but since it happened on an OTA Update and I can reproduce the same errors every time, I'm hoping there's still an option left for a fix.
Holy crap. As I was typing this and restoring Emotion, it fully installed and booted. I have 4G! I don't know if that will fix the FC issues, but I have regained a little hope!

I'm still getting FCs and restarts. The more I use it the more it happens, but at least with EmotionOS, It's more limited. Only about 3 or 4 a day compared to 10-20.
I'll try one more flash and I guess tough it out until my contract is up in April.

I can't help you with EmotionOS (haven't tried it yet), but if you want to stop the Google Play Services crashing in NSeven you can make your way to Settings - Applications, then select Google Play Services - Permissions and give it all permissions. It's a bit of a chore to get there when the warning pops up every five seconds, but it will stop once you do that.

So my plan is up and I'm probably switching away from Samsung after this incident. Looking into the pixel or XL. If the v20 is out for Verizon, I might get that but I'll see what looks good when I go to the store today or tomorrow.
I think I've narrowed down my issue to a heat issue. I fixed the 4g and Google play crashes but my phone still locks up or apps start a cascade of crashes. If I power down, I can't restart the phone. If I restart, it powers down but does not turn back on. I remove the battery for 10+ seconds, put it back in for 10+ seconds and it won't turn back on. I'll leave the battery out for minutes to an hour and its a crap shoot.
I can only boot normally or to download mode. TWRP no longer loads. I tried reflashing it and I get a no pit fail. I'd probably look into fixing this but at this point it's not worth it.
What I discovered works is putting the battery and phone on a cool surface, putting the battery back in and placing that on a cool surface and then try to boot up. However, neither my phone nor the battery feel warm to the touch. So that indicates to me something is either off in the sensors, preventing it from turning on or more likely it's a power issue or at least a hardware issue, preventing a constant current or something along those lines. Dips in power could explain apps crashing and the system inexplicably turning off. It would also explain why I can't turn it on easily.
It's really a shame because I liked this phone so much and if the new note was out, I might give it the benefit of the doubt. But last night my Samsung tablet decided to install the updates I've been putting off because they're the same ones that broke this phone. So timing wise, I'm done with Samsung and will try a new brand. Only issue I see with pixel is it doesn't have a removable battery so hopefully I don't run into this issue on that device!
Thanks for all the help xda. If it was a solvable problem, I'm sure I could have fixed it with your help.

Final entry.
I got the v20, and spent a day trying to get my note back to factory. I thought I was doing something wrong, but eventually flashed a kernel, recovery, bootloader and then full Rom (I think it was BPA1 but it could have been CPF3, I don't have it in front of me). I was getting error after error, no PIT partition, mmc check fail, use the Samsung Recovery Assistant, and a few others (again, it's not in front of me so I may have gotten it wrong). The big one was a write disk failure when I was trying to flash the full Rom. I fixed that by flashing kernel, bootloader, recovery, then sticking the battery and the phone on the freezer for ~5 minutes before trying to flash the full Rom.
I updated via USB after that using recovery assistant. Probably completely unnecessary, they just needed to get to the factory reset screen, but when I bought my phone, I couldn't trade in the note because i couldn't turn it on. They gave me $86 for it. Anything less and i would have considered just taking a hammer and microwave to it. Good riddance!
Still a little sad, I loved this phone right up until marshmallow dishonored and killed her.

I know a lot of people are blaming software, but I'm fairly certain that the problems in many cases are caused by failing hardware. I went through many of the same trials and tribulations with my Note 4 (except I never rooted the phone). I finally contacted Samsung Customer Support and sent the phone in for repair. They replaced a lot of the hardware including the motherboard and returned the phone in "like new" condition. I've been using it for a few weeks now and the performance is flawless.
I was planning to get either the V20 or the G6 if I wasn't able to get the phone fixed. How do you like the V20?

I'd agree that it's most likely hardware and having to put everything in the freezer for it to when confirms it for me although I have no real expertise to say so. But I'd argue that the update created the hardware issue, it was night and day with the update. It was working 100% and then directly after the update to marshmallow, it started having catastrophic issues. Oh well, it's nice not having to pull the battery every hour or so.
V20 is pretty nice. Having used EmotionOS for a few months the switch to the Nougat was pretty smooth. The xda forums for it are a little more limited but I didn't start messing with my phone until it broke and I'm hesitant to try with a new phone given my limited knowhow.
To be honest it's not a big difference in day to day usage from the note 4. Which I like!
+ I never used the finger print scanner but really like it on the v20. I didn't bother with a screen lock before but now I'm protected and have a just as quick access.
-the grip is too slick, I feel like I will drop it. The note had that rougher back which I liked better. A case or a replacement cover should fix that though.
+ I like this top menu screen, I have quick access to a few select apps or can turn the flashlight on or whatever. I'd like it more customizable, I find I switch screens too much when trying to just pull my top menu down. If I could put everything on one tab and combine their special buttons (ie the flashlight button) with apps, it would be perfect.
-the back button and menu button are switched. I can probably customize that but I don't yet know how and by the time I figure it out, I will have relearned that habit. It actually is probably a better placement for how I hold the phone but I'm a big fan of choices.
+ upgraded camera, sound, storage. I don't notice the screen size difference, but it is a lighter phone.
-bloatware
All in all its a good shift from the note 4. I'm happy to be off of Samsung and still have the same basic user experience.

I have had the exact same problem with my note 4. It wouldn't last 30 seconds at a lock screen from a cold battery before it would start boot looping, and the longer you left it in, the worse it got. Google told me I needed a new battery from several other forums and places I read. So I ordered one and replaced with a genuine Samsung one direct from them, and it didn't change anything.
I figured out it was heat related and I had it sit on an ice pack and it would run and work fine as long as the ice pack held out, about 2 hours. I've down graded, flashed, rooted the boot loader, installed a recovery console, flashed to different versions, all have the same problem. So I've kind of reserved myself to the fact it must be a hardware problem. Perhaps it was caused by the update, but nothing software change wise seems to be able to fix it. Did wake-loc fix as well. I've spent the last week with mine trying everything in the world and every evening having it on the ice pack hooked up trying whatever I could think of or read up on doing, and basically as soon as it warms up, it starts doing it again.

In my experience, it gets worse and worse. The day I bought my v20, I tried to trade it into Verizon but couldn't even turn it on in front of the rep. I thought I had timed the new phone perfectly but still wanted the $80! Fortunately I got it working after the weekend and just stuck everything in the freezer before I walked to Verizon.

Just out of curiosity, what phone did you wind up going to?

The LG v20 and so far so good!

IMEI Printed On Device

Does anyone else have their IMEI actually printed on the back of the device? I'm not talking about the sticker than you can peel off, but printed directly under the LG emblem? I've go through several devices a year, and have never seen this before. I'm wondering if I got a bunk device, because I've had all kinds of issues with the phone since I picked it up this past weekend. I got a T-Mobile version through JOD. The issues I've had are bluetooth and wifi connectivity issues. Both go on and off randomly through the day. My bluetooth took awhile to set up in the car, and sometimes it will connect the media, but not the actual phone (if that makes sense). Also, I've been having some crazy lag. Camera takes about 5 seconds to open, and certain apps like YouTube and Google Play Music take about 5-7 seconds to open as well.
Any advice is appreciated.

They all have the Imei printed on them
Not sure what that has to do with any of your issues though

Oh okay. Good to know. I thought I somehow received a test or early release device somehow.

my T-Mobile G7 (via JOD) has the IMEI on the back (printed) but my phone is running great. I've had no issues and quite enjoy it. I jumped from an S9 and couldn't be happier. Not that the S9 is a bad phone, I'm actually just digging this LG phone more which is surprising.
Have you tried to factory reset the phone? if so and it still gives you issues, take it back to T-Mobile as a defective unit and get another one.

I also did a JOD upgrade from the S9 and agree it is a good phone. Just wanted see what to G7 had to offer although I was hesitant after several issues with 2 V30's. So far I'm liking it. Worse case scenario is if it makes me mad, I can always JOD back to the S9 or S9+.
I also couldn't really just the color. I got the Raspberry Rose. And an FYI, the S9 also has the IMEI printed on the back in the same place as the G7, it's just harder to see because of the darker color of those phones.

yeah, my local store only had the raspberry rose but I wanted silver. So the store manager waived overnight shipping for me and I got it the next day via shipping. Same here, if I decide I don't want it longer than 30 days, I can go back to a S9... but so far I don't see that happening unless something major crops up.

I was coming from a S9+, and it was the 1st Sammy phone I've had that was actually smooth, and had great RAM management. The G7 I got a few days ago was a bit of a let down. I did 2 factory resets hoping it would help, and it didn't. I really want to give this phone a try, so I just went to T-Mobile to swap for another unit. Hoping this one performs better.

It should. Mine runs great. Even better than the v30+ I have.

New one is MUUUUUCH better. Feels "right" now.

My camera opens a little slower with AI on, but not with it off. The only issue I've had is the light bleed at the bottom of the screen.

there are some issues opening apps, especially the LG apps like messaging. this will likely be ironed out in the coming updates, but i have noticed them. this phone tends to act more like a SD835 rather than an SD845.
every manufacturer is rushing to market these days. the past few phones i've tried have all had lots of bugs. my s9+ had so many that i had to return it. give it time. eventually LG has to give us an update, although i'm already frustrated that it's the middle of the month and i'm still on May security patch.

Mine had a sticker.

Yes there is a sticker that can be removed but look lower on the back below the LG logo you will see it printed on the back. It's really small.
