[Android Q&A, Help & Troubleshooting] mazabin:
Hi!

I'm new on XDA, so I'm sorry if the thread is placed in wrong subforum - if it is, I'm asking mod to move it in more proper place.

I bought Lenovo Lemon 3 - it was advertised as Vibe K5 Plus, but apparently the seller wasn't that reliable as I thought. As far as I know, the differences beetwen these models are little or none, but I have pretty big problems with the phone.

First of all it has some preinstalled software, which isn't in Play Store and some of them I can't even find in the net. The apps I would like to get rid off are KingRoot, MaxxAudio and SecurityIT. I successfully managed to disable MiBrowser - with help of KingRoot tool Purify actually. I tried to disable SecurityIT also, but if I do that I can't enter Settings->Apps. When I try the com.android.settings is stopped and it's not working till i enable SecurityIT again.

Second of all is that process com.android.phone is stopping randomly. Sometimes I click "ok" and I it starts working again. But sometimes it keeps crashing until I restart the phone. Since it's a dual sim phone and I'm using only one sim I thought that maybe this is causing a problem, but inserting second card wouldn't work, so currently I have no idea what is causing the problem. I tried cleaning cache and appdata with no effect. If the process is crashing and somebody will call - the phone restarts itself when I try to answer.

Thirdly it's hot. Even if I'm not doing anything and all apps are off and Im charging the phone it sometimes says that it can't be charged because of too high temperature on battery. Sometimes it works fine, but sometimes it's too hot too touch and I don't know why.

Oh, and one more thing. Something is installing random software. It looks like every time I open Chrome something is opening new tab and redirecting to PlayStore. I am trying to close these tabs while they're loading, but sometimes it loads too fast. Every morning I uninstall some new app, which is apparently installed by night. And those apps aren't added to my Play Store Account. I have disabled unknown sources, but I can see that phone is checking for updates around 2 a.m - so maybe those apps are from there - but I can't see any possibility to disable auto-updates. I have disabled auto updates in Play Store and I have "Lenovo Enhanced Experience" unchecked. Most of apps I installed from Play Store are games I had on the previous phone so I am sure they're not dangerous. Any ideas to prevent the installation of this unwanted software will be appreciated.

Since I used KingRoot to disable MiBrowser I apparently rooted it, but I was reading that this works only with KingRoot installed and with internet connection. And it's sending some data to China, which is not nice. RootChecker says it's rooted.

Lenovo Launcher it's not great either, I downloaded Lollipop Launcher from store and it works fine, but I had to block Lenovo Launcher from autostart, because it was very irritating and was enabling few times.

I am living in Europe so I was thinking is it possible to put on this phone Lenovo Vibe K5 Plus Stock ROM? Or is it this "trashy" like the one I have? I really like specs of the phone and I don't wanna return it, but I don't like the software behavior. Can you tell me what I can do to improve this? I don't care about warranty and I would like to have pure, non trashy Lollipop, so if it is possible somehow I would be glad for any help.

Thank you in advance for any help!
