Hi,

Today, at work, I noticed slower app response. It took longer for them to start, and typing wasn't exactly the fastest either. But, since I was working, I didn't had chance to use it for more than few minutes so it didn't bother me. After work ended, I tried to text a friend, and it actually took me quite some time to do it.

Typing the code to unlock the phone took quite some time, sometimes it didn't even register that I pressed a number, typing a message too, though here it was with both text and numbers. Starting apps was slow too.

At that point, what I saw with "top" command, were 4 processes, each one taking about 45,6% of the processor, each one ran by user "nemo".

Since at that point I was still walking home, I figured I'd try to see if they finished doing whatever they were trying to do by the time I got home.

About 15 minutes later, still the same situation, so I decided to check what was occupying processor.

I ran "top" again, wrote down the PID's and decided to check which apps were they: (pid - cat /proc/{pid}/cmdline)

922 - /usr/bin/lipstick-plugindevtouch:/dev/input/event0:rotate=0-pluginevdevkeyboard:keymap=/usr/share/qt5/keymaps/boston.qmap--systemd

879 - /usr/bin/timed-qt5--systemd

933 - /usr/bin/msyncd

1139 - /usr/bin/contactsd

About two minutes into writing them down, two of them finally "finished", while two of them occupied around 89% (922 & 933). Few moments later, 933 finished and 922 was occupying about 92% of processor. Few moments later, 922 finished too and now my phone works "normal" again.

I have Sailfish OS Version 1.0.2.5.

Apps I have installed are following:

• Maps
• Calendar
• Mail
• Clock
• Calculator
• Documents
• Notes
• Media
• Microsoft Exchange
• Snow White
• Tethering
• chro.mono

I don't have Android support installed, nor any android apps. (Seemed annoying, most comments I read were that it either doesn't work, or works partially for most apps so I just figured I'd wait for native ones)

I didn't notice this behaviour before, so I'm not sure if it could be the reason, but difference between today and days before today was that I got tired of turning on/off mobile/wireless manually based on whether I'm in apartment or outside, so I turned both of them on.

Other difference was that I turned the touch screen vibration off since, well besides it probably draining a nice amount of battery by the time someone writes a normal message, it is annoying when it vibrates like I'm receiving ~20 messages when I'm trying to type "at work now, can't talk".

Thank you,

Ranko

Also, my phone just stopped responding to the point I had to reboot it... so I'm pretty sure this is some kind of a bug... guess I'm back at manually switching between mobile/internet and seeing if that helps...
