12.17.2015. Yea, my 4g service quit,too. Only get 3g. Was on phone with tech support for an hour and assured me my phone Samsung J1 should receive 4g. She kept saying i should go to contract???. It is prepaid and my wife is contract and she gets 4g everywhere. I also did Verizon troubleshooting, no good. Removed battery and sim card for 60 seconds no good. I pay for 4g so Verizon should provide 4g, I think it's a conspiracy by Verizon to bump up prepaid customers to contract. I saw an update Oct 1, 2015 it's around the time 4g . Otherwise great phone with lots of unique features. disappeared. I noticed in settings LTE service "grayed " out.? Going to Verizon store soon.Otherwise great phone with lots of unique features
it does not hang if you urn off powersaver mode it limits cpu performance making it lag and just usable for call and text

Limited internal memory available for use out of the 4GB internal memory of the phone.this is bad.

Bought mine yesterday but has been hanging every time I install apps nkt
Usman, 12 Dec 2015When we had 512 RAM at that time Min requirement of applications were also Max 512 RAM but now... moreCould be Samsung using intelligent auto ram booster but anyway the device memory should not be filled up that could cause problems for auto update and also can added extra loads to the ram. Just my thoughts.
Cheap Have More Fun, 01 Dec 2015hanging problems are a concerns of your telco not of a smartphone, in the old days all desktop... moreWhen we had 512 RAM at that time Min requirement of applications were also Max 512 RAM but now its not .
