I have a bionic which is in excellent condition so I don't want to replace if I don't have to. The problem is that it runs extremely slow much of the time and as an example it can sometimes take 10 - 20 seconds to tap through the security lock and unlock the phone. Launching apps is equally slow and I've taken to running system panel lite to shut down apps after which it runs more quickly for a while. the phone is not rooted and is running 4.1.2. Is there any hope reducing the latency of this phone? thx!
