Hello, Do yourself a favor and clean out your phone real good before you do the update! Do a partition wipe and a good cache clean 1st. This can only help. the partition wipe will clean out all of the old temporary and junk files that can cause the new update to malfunction. This is only the minimum precaution you should take. Doing nothing will in many cases cause a bad update. I am only trying to help. Good luck.
i was just told in chat with a Sprint rep...
Nathan S.: We can update it via store and it will be our store representative who will set it up for you. But solicit advice, I would suggest to stay on the current version since the new one needs to be enhance, just giving an advice.
I updated my S5 on Saturday the 14th. The UI was very bad on my eyes. That all white background that I could not change. The battery started draining and I have very few app mind you. I dont do social media like that. I did some net surfing and went back to Kit Kat 4.4.4.
