"Pokemon Go is lagging too much"

#PokemonGO: I have been experience terrible lagging in Pokemon Go. I try to open the menu an scroll in my Pokemon and it stucks. The game seems unplayable. I cannot play gyms because the game freezes too much.I cannot throw a pokeball properly because while throwing the screen becomes unresponsive and I end up wasting it.I cannot perform more than 30 evolutions during the 30 minutes of the lucky egg because the game will freeze and I will have to restart many times.Can you please suggest all the possible ways to solve this?Should I buy a new phone?Currently it seems my phone has 550 MB of free RAM so I guess this is being used by game.I have cleaned the cache but it won't totally solve the problem.Thank you all in advance. via /r/TheSilphRoad http://ift.tt/2h8U73b
