Hi, I recently did the update from kitkat to lollipop on my Grand x Max + and ever since my network signal is intermittent. Sometime I cannot connect for long periods of time and sometimes it works great. I tried a network enhancer app which seemed to help by adding more sources for my signal but I still lose signal. Before the update this never happened. Now it happens all the time. Does anyone have this problem besides me and is there a fix?
