[AT&T Samsung Galaxy Note 4] yasirfaheem:
Hello Smart People,

I have an unlocked at&t note 4 and for the past 2 week my phone will freeze for 1-2 minutes then it will be useable again or if it is not doing that will randomly reboot when I am using the phone. So benging of last week I called tmobile since I have them now. I spoke to tech support. Told them my problem and they had me turn off the phone and take the sd card out and then boot into recovery to clear the cache. That did not work. Within 5 minutes of have the phone back at the home screen it froze again. So tmobile said that it was not the sd card in the phone. Told me to turn the phone off and put the sdcard back in the phone. Then I rebooted back the home screen. They said that at this point all I could do was back the info on my phone and do a master factory reset of the whole phone. I told them I could not do it right then and there. They said if it still happens after the master factory reset then you will need to get the phone reflashed to have the software fully reinstalled and they could not do the reflash of the software since my phone was an at&t branded version of the note 4 so I would have to call at&t and see if they could reflash it for me. So the next day I backed up my phone using samsung smart switch software on my pc and master factory reset the phone from the recovery menu. When it was done I resetup the phone and it still froze and reboot randomly. So I called at&t and spoke to tech support and told them my problem and what tmobile say to do. They told me they could do the reflash but since I am no longer a customer they was nothing they could do for me. But I could go to best buy to a Samsung experience store and they could reflash my phone with for me with the latest software that at&t had out. So I went to the Samsung store inside of best buy. I told the lady my problem and what tmobile had me do and what at&t told me. She told me she could do the reflash but I already had the latest version of the at&t software on my phone all ready. I told her that tmobile told me the hardware in my phone is all good and that however I got the at&t update it did not apply correctly and that I need a reflash. She took my phone and started to plug in to her computer to do the reflash. After it was done she gave me my phone back. On the screen it was in recovery mode trying to reboot back to the phone screen. I showed the phone to the Samsung store lady and she told me I had to wait and it would reboot to the home screen. I thanked the lady for helping me out and left the best buy store. Got to my car and the phone now had a black screen so I took out the battery and put it back in and turned on the phone and it booted in to recovery mode not the home screen. From the recovery screen I picked reboot the phone and once again booted to recovery mode. So I walked back in to best buy and talked to the Samsung lady and was like this is very weird it should not be doing this. She also took out the battery and put it back a few times. Still phone was rebooting to recovery mode and not the home screen. So she called her tech support to figure out how she could fix my problem since now my phone was 100% not useable. The Samsung lady’s tech support had her plugin the phone to the computer again and reflash the software. But it failed at 3%. She was told to tried it again it failed at 20% this time. So she was told try it again and it failed this time at 50%. So she was told to try it one last time and this time it went all the way to 100% and she keep the phone connected to the pc until it was fully rebooted but again it rebooted to the recovery more screen not home screen. She told me that she would have to keep my phone and next day ask Samsung for the full flash of the software to download for my phone since she only had the latest update. So I left my phone with her and waited for her to call me and let me know that my phone was all good to go. I went back the second day after giving Samsung my phone and the lady told me that she did not run the full flash because she came in the first day after I give her my cell phone and it was at the home screen. I thanked the lady and left the best buy store. When I got home I download an app from the google play store and the phone rebooted on me. So the problem is still there! The phone so far has not frozen on me which I guess in grand scheme of things is good, but I am not calling this over just yet. So smarter people of xda Is there anything I can do to fix this phone so I can still use it and not have to worry about it or is it time to just bite the bullet and get a new phone even though there is nothing out that I like.
