[Galaxy Note 3 Q&A, Help & Troubleshooting] zxybabydoll:
5 Samsung Galaxy Note 3's!! Any new info? Here is what I have tried...

To Start, This is what I have gone through- Sorry it is so long.- Unrooted- Tmo Note 3. ISIS MICRO SIM. I was using a regular SIM in my SGS4, TMo suggested that I change to the new ISIS Sim, So I did.

Note #1 (Black): I got my Black N3 from a TMo store on the 3rd of October- I set the phone up and had everything the way I liked it but after about 3 hours, The phone was restarting itself- while sitting on my desk- It got into a BootLoop. I pulled the battery and it restarted fine. But When I went to bed I plugged the phone into its charger- still on, and I awoke in the middle of the night to my phone stuck in boot-loop- It stayed in a boot loop for over 6 hours!!! every time I pulled the phones battery out and put it back in the phone- (yes, I waited for a few minutes to put the battery back in)- it kept up where the boot-loop left off. first thing the next day I called Tmobile- they said to exchange the phone for a new one asap.

Later on the 4th: new Note 3 in hand

Note #2 (black): When I exchanged the device the TMo employee that helped me purchase the phone was doing a few really weird things to the phone when the phone was starting it for the first time-( Basically playing with my new phone), He didn't allow me to set the phone up at the store so when I got the phone home and set up- I did a reformat on my Samsung class 10 32GB Micro SD Card. side loaded (from my PC directly to SD card) my 140 MP3 Songs, My 10Gb of Epub and PDF Books and 10GB of pictures. There was absolutely NO app or other data on the device- I placed the SD card in my phone and reset the phone as soon as I got the device home. after re-installing my apps and restarting the device, it got into a boot loop. I called Samsung directly and they said that the phone was defective and to immediately return it for a replacement. They said that the phone was obviously damaged since I reformatted the phone and they had NEVER heard of this problem so the device MUST be faulty. I was very clear that this was my second phone and that this phone was only out for literally 2 days at this point. I then called Tmo and told them Samsung's position at this time and they said to try a few things, First- reformat the SD card in the phone before doing a Factory Data Reset (FDR), instead of logging into my Google account, Samsung, Etc. skip to the home screen so the phone can set up fully, then go into settings, accounts and then log in WITHOUT allowing the Google Apps to Auto download. All still with the SD card NOT attached. Then download no more than 10 apps at a time then do a system restart,. I did that- FOR 6 HOURS!!! Then I put in my SD card- I restarted the phone 3 times- No BootLoop. Then I restarted the phone 5 times after ALL of my apps were installed With the SD card in. No problems. I waited a few hours, I didn't open or use any apps and then after the 3 hours, I decided to restart- BAM! Boot loop! I immediately went to Tmobile for another replacement- the next day.

Note #3 (Black): I went to the TMo store and as soon as they pulled the phone out of the box, I took over (setting the phone up from the opening display). I was at the Tmobile for over and hour and a half re-installing the apps and settings- again, everything was fine- No Boot-loop. So I took the phone out of the store and home. Continued to Re-installed the apps the same way as described in NOTE #2 except that I just manually installed the apps that were previously in the last note- Alas, an hour later, Boot loop. Nothing stops the boot loops- I cant even take the battery out to get it to stop- I have to do the Vol. Up, Power, Home key to get it to reboot. However, I could restart the phone if I removed the SD card at the right time in the Boot-loop sequence. My 3rd phone was the first one that during the Boot-loop it would get all the way to the lock screen before getting back into the BootLoop. I called Samsung again, they said that it is again a defective device and to exchange it. They put me on hold and said that their support manager said that this is an isolated indecent and that they have NEVER heard of this problem before. I called BS because I explained that this thread is full of people with this problem and a few people on this forum have said that they were also calling Samsung for answers! I tried their answer which was to FDR this handset. It didn't work. Again, I exchanged the device.

Note #4 (Black): By this time I am PISSED!!! I was scouring the internet on my own for answers, but most of what I was finding about Boot-looping was that it was happening to people who were Rooting their devices- I have never rooted any device I have owned. I went to the same store and exchanged the device AGAIN at Tmo, they were totally cool with the exchange (Surprisingly). I again did what I was told and followed the steps with the Note #2 above- minus setting up the apps. instead, I installed just a few apps that, after the boot-looping- and after the phone would restart (via the Vol. Home, Power buttons), were missing the icons in my app drawer- with the SD icon and grey logo. I installed just those apps and even played a few of them- One was Incredipede- and I restarted the device after doing that and No Boot-loop. So again, I went home. 2 hours later Boot loop appeared with only a few other apps installed. I called Samsung- 2 hours later- at level 2 support- they had no ides what was going on! They said that the store I got it from must have gotten a bad batch. I want to mention that my Husband Got a Note 3 from the same store at the same time and the same color as me and he has NO issues whatsoever!!!!!!!!! I said fine, I called the Tmobile store that I purchased it from and told them what was up. About everything that I had gone through and that Samsung thinks it was from a bad batch- The manager agreed to pull some strings and let me exchange the device at another store and so I got on the phone IN another state and about 40 miles from where I got my Black Note 3's. One store was willing to do the out of store exchange- with a White model. I jumped at the chance because the way I see it, Different store, State, Color- There is NO WAY that this store would be carrying a bad batch also! WRONG!!

Note #5 White): I got this phone on the evening of the 9th. All was well with it at first- Every single app that I put on this phone was the same ones that were on My Galaxy S4, I again did all that was recommended for the Note #2 (Above). I restarted the phone at least 10 times after getting everything set up- No Boot-loop. Then all of a sudden =, right before Bed I decided to restart it "one more time" and... BootLoop! I did the Vol. Power. Home Key, Just chose to Reboot System- and it loaded fie with the SD card in at and everything. The next morning- I called TMo- They "Don't know what to say except return the device"- I don't think the device itself is faulty since I have had 5 Note 3's from 2 States and 2 separate colors- and I have used 4 different 32GB micro SD cards (Class 10's) and 2 16GB Class 10's. One was brand new still in the packaging! So I called Samsung for the 7th time at this point- They always say that they have NEVER heard of this problem and today was no different. I went through their Tier 2 support again and went through a few more things- Nothing helped- The Man said that I must be wrong about whats happening with the phone because nothing added up between all the phones and symptoms that my Note 3 is experiencing. He said to deal with it or exchange it. I called out the forum info I have learned from you guys here and he still didn't believe me. Instead he went with this weird- Absurd idea:

My Gmail account is causing my cellphone to corrupt itself. No, Not the apps- My GMAIL ACCOUNT- as in when I log in to ANYTHING gmail related it is corrupting the WHOLE phone- He said to get a new gmail account- So I did- And Still a boot-loop. But after going through another 2+ hours with this guy- I called Google myself to ask about this little theory about Google-Gmail being the issue- he sent me to a supervisor who called BS on Samsung! I then called Samsung back to ask for further "Help" and to tell them that the whole GMAIL corrupting my phone didn't help as I logged into a brand new gmail account and it still happened- However- a Woman from level 1 support said to try a new Sim card- and I found a brand new one from my old S4 box- NEVER BEEN USED IN ANOTHER DEVICE- and since switching it with the ISIS Sim card- No Boot-loops (yet) I am not going to hold my breath- but it has been almost 24 hours with ALL apps and my SD card with data- from apps to my personal media- and my settings all the way I like them- the one thing I have been doing- On a whim is turning off Sync and WiFi before Restarting the phone.

That all said- I am current on my 5th White Beautiful Note 3- everything works great except Bootloops- I hope that this may help to find an answer since this could still happening to me/Others and I know that this is getting a bit ridiculous! Everyones apps seem to be causing different issues- Someone, Somewhere has to be the genius we all need to fix this without Rooting!! PLEASE HELP!!
