i think you may be correct... i cannot prove this but i have a theory...
when i first got this phone it was used, it was rooted but stock, never had a rom flashed and im pretty sure it rebooted on me once or twice like that, and i had and still have NO plan at all with metro (so never had 4g), I only use wifi lol but since i started flashing roms with the mod'd kernels i have not had the reboot happen to me at all!!! not once lol.. so you may be correct, it could be the kernel, but i have yet to have 4g on this device yet so im not sure if that will or could cause a reboot...
but if it does, than sadly i will be moving on to another device lol there no friggin way im dealing with random reboots on a 400 dollar phone
so the one thing i can think of to test it is to...
first i will upgrade to zvc, but i wont get a plan yet, ill just keep zvc for a while and do my daily usage.. if it reboots then the kernel is def the suspect...
then, if we have no reboots i will start a plan with metro and crank the 4g to its friggin limits lol then if we have reboots after that we will know what the hell the problem is lol
if anyone would like me to extend this testing method in any way please let me know!!! i would love to get to the bottom of this A.S.A.P.
so after some time giving these few methods a test run i have come to a conclusion:
after purchasing the device i had to wait 30 days before activation, so i had time to test these out..
got phone on ZVB, had NO data plan through metro (NO 4G) and never had an issue with rebooting, not once
upgraded to ZVC, same results.. had no reboots what so ever.. so after downgrading back to zvb i decided to test other things to see if maybe there was a specific 'thing' causing the reboots, but after testing everything available i still had not come across any rebooting issues...
so after my 30 days were up i finally got a data plan through metro
soon as i got home i ran through these same tests but i noticed i wasn't getting 4g at all.. tried upgrading, downgrading again.. still nothing. i thought it was something i did so it delayed my testing a little..(turns out metro was doing tower 'work')
the day i got 4g, litterally the split secong my phone caught a 4g signal it had rebooted lol
so of coarse i downgraded to zvb, did the same tests and rebooting ONLY happened with 4g/data enabled same for being rooted with various kernels, would reboot only with 4g enabled..
Next was ZVC, results were the same!! rebooting only occured when 4g data was enabled..
so my conclusion is that 4g is without a doubt the culprit of our beloved rebooting issue
the only thing i cant figure out is... why...? it doesn't seem to occur while doing any specific 'thing' it seems more 'random' if anything.. unless theres something behind the scenes that im not noticing...
