i write because i don't know what to do.
I have two strange problems on my Nexus 5, the first (less important) is that when i put the phone in landscape it starts to lag, but after a few seconds it works fine...this problem is less important because a reboot ever fix the problem...but what can be the cause?
The second problem that is bad and it is that i have issues with my mobile data...when i tried to use internet it is really slow and it doesn't work fine...in first place i thought to some network problems but people with Nexus 5 and also other phones told me that they haven't any problem with the same carrier.
Then i clean flash a new rom (Carbon Rom) and i noticed that the problem was gone..however after some strange reboot in calls i decided to revert to stock rom (again with clean flash) and the problem with network is here again! Is a baseband (modem) issue? Maybe the Carbon Rom uses a different baseband?
I tried also to disable Xposed (that i use on stock rom and that there isn't in Carbon) but the problem is still here!
Of course i installed the same apps on Carbon and on Stock then i was in the same conditions. I used franco kernel (both on stock and Carbon) and changing kernel is the unique thing that i didn't make but i think it's useless!
What are your advices? Thanks in advance!
