I changed, but to the very same phone, after my last S3 LTE crashed
Third time bought I9305, for me and two times for my wife
. This device has more power than we actually need.
Every has their own needs, but some features when increasing their parameters make more problems than benefits.
- biger screen resolution consumes more power and needs a stronger GPU
- more MPix on camara with the same physical size of sensor worsens the quality of images
Main problem in every device is software, that is crappy much often and S3 LTE is good example here, cause was introduced after normal S3 and shortly before the Galaxy S4, whose sales were more important for Samsung than support for previous products.
Any Cyanogen/AOSP/AOKP could be good replacement, but has a few problems with functions that for certain users are very important (camara, compass).
2 days before I downgrade to stock 4.1.2 with JKay mod and for me this is perfect setup (with Nova launcher, exDialer, Chrome, and for tweaking: Autostart, Disable Service, Greenify Tasker)
