Hi. I have a galaxy s3. I have around 43 apps installed. How many apps do you have? Is it considered alot? Does it have an effect having alot of installed apps?
43 apps are not much. Performance depends on the processor speed, RAM and free space avaialbe (which in turn comes to number of installed apps). So unless and until you feel your phone sluggish you can continue installing apps
I've around 60 apps (and counting) and I don't see any performance problem in my Nexus 4...
