Phone: Moto G5S Plus
Plan: My Choice + 1 GB
I purchased this phone from Republic Wireless in January 2018. It was great up until about a month ago. Then it started developing some odd performance problems - if this were happening on a Windows PC I would bring up the Task Manager to see what’s using up CPU resources, but I haven’t really found a good analog on Android. Here are some of the behaviors that seemed to start all at the same time:
Phone needs multiple tries to unlock. Sometimes I will press the power button and I will see that the backlight turns on but it is otherwise all black, and the timeout just turns the screen back off after 10 seconds. Or sometimes I’ll see the background and the back/home/square buttons (should be microphone and lock buttons), but no notifications - buttons shown are non-responsive, and the phone takes 5-10seconds to populate the notifications, and then I can start using the phone. And then sometimes it works just like new, immediately giving me notifications and being perfectly responsive.
Phone forgets that I’ve already entered the PIN to allow fingerprint unlocking. It wants the PIN every time, and then after like 5-10 times it finally decides I can use the fingerprint recognition to unlock.
My train ticket app is incredibly slow. In Chicago, the “Ventra” app requires you to activate a ticket, and then it shows you an animated screen you have to tap in order to prove the ticket is valid. It contacts a server to generate/check the certification, and this used to take ~3s. Now it usually takes about 60s. It will show the “generating ticket” popup for about 10s, and then show a black screen for 30-45s. Once it starts rendering the animated screen, it takes about 10s before it will actually respond to touch. It’s been a real nailbiter a few times with the conductor giving me the “why didn’t you activate your app earlier” look. As far as I can tell, this is the only app that is giving me problems.
Rebooting does not appear to help in any way, the phone is immediately slow to show notifications. Wondering if this does indeed sound like a CPU issue to others, and whether there are CPU analysis apps or built in tools that people recommend. Or if I need to start uninstalling apps.
