I have about 50 apps installed on my phone (not counting system apps). And my phone is absolutely unusable this way. Everything lags so bad that I can barely even enter my lockscreen pattern. I assumed this was because the apps can magically run in the background as services or whatever, but after freezing about 40 of them and making sure that only a very few services were running like whatsapp, my alarmclock app and my firewall app. My phone is still extremely slow.
Why is that?
Back when I only had these 10 apps installed that are running right now, everything worked pretty smoothly.
So what is wrong? A frozen app shouldn't have an impact on performance in such a way. Is there any way to get it fast again?
I've already removed as much preinstalled apps/bloatware as possible and cleaned the system using SD-Maid and used Autorun Manager to disable a ton of receivers that could start some apps. But it is still really slow.
