If you have Huawei P Smart mobile phone, you may have noticed its annoying tendency to kill third party background applications randomly, even those set to be managed manually:
The auto-launch setting also does nothing (at least on my phone using excellent Blokada and Auto Auto-Rotate applications).
To fix this you’ll need to follow the steps outlined here. I didn’t have PowerGenie app they mention installed, but I did have something called hwaps, and uninstalling it fixed my problem with a phone randomly killing background applications and not starting them on boot.
You can restore deleted application by issuing the following command: adb shell pm install-existing –user 0 com.huawei.android.hwaps
I bought Samsung Galaxy S2 & Samsung Galaxy Note 10.1 couple of years ago and for the better part of the last half a year both devices became unbearably slow. I went through the usual motions of cleaning junk and cache and memory but nothing helped, so I just kinda written of bad performance as a case of “applications becoming more bloated and device performance staying the same”. However, recently I read that Android didn’t have TRIM support until 4.3 version (more about this here). Problem is, that highest supported version of Android by Galaxy S2 and Galaxy Note 10.1 is 4.1.2. I didn’t want to try custom roms, so I tried fixing my performance using third party software Trimmer (fstrim). Before trying this program you need to have your device rooted, you can read about it here (Galaxy S2) and here (Galaxy Note 10.1).
