I want to improve the signal of my 9350. Does anyone know of any products, tricks, or tips to improve signal? My biggest issue is when I'm watching videos on youtube. Really looking forward to some good ideas.
Other than complain to Sprint about poor service where you are, I don't think there is much that can be done. If you have been with them for a while you could get a free signal booster box (my friend did with a similar issue with her iPhone and her family has been with them for like 15 years now so they got it for free without the $50/month service charge for it).
Install the app called "Signal Refresh". I use it quite a bit and it seems to help some.
It doesn't do anything to boost the signal strength. What it does do is disconnect the phone from the network and then reconnects it again, causing the phone to re-register with the network and find the strongest signal that's available.
