Crashing and much more

My planned device (Lenovo Yoga Tablet 2 per 33 cm (13.3-inch) tablet PC (Intel Atom Z3745, 1.3GHz, 2GB RAM, 32GB eMMC, touchscreen, wireless, pico projector, 4G LTE, Android 4.4 ) Platinum with Android 4.4.2) I get the app to run only garnicht.
Start crashes right expires in Semi background Next (dropdown menu) open from there brings nothing but further crash report.
Funnily enough run 2 processes the main process so the graphical interface that crashes constantly and he; Mini Player runs in the status menu.

On my second device (Samsung Galaxy Note 3 smartphone (14.5 cm (5.7 inch) AMOLED touchscreen, 2.3GHz, quad-core, 3GB RAM, 13 megapixel camera, Android 4.3) white with Android 4.4.2) Is it possible to open the app but running very slow and depends on when adding and subsequent playback.
Music is played on the background Still process and end the process makes the app then return to normal but inertia and hangers are available at all times.

The design is top but does not help if the app only runs very sluggish and constantly crashes and indeed even on high-end devices.
Solang Poweramp is still my number one stay.

The Direct Crashen what my predecessor and I have is probably due to the excessively high resolution which my tablet and the smartphone LG G3 (14 cm (5.5 inches) Quad HD IPS display, 2.5 GHz quad-core processor have Titanschwarz from speakers Both qHD display and the app can not handle is that I've seen in other apps crash either directly or shortly thereafter -, 13 mega pixel camera, 16GB memory, Android 4.4).

Update Version 1.3.5

After the update to version 1.3.5 of the crash bug has been fixed on the qHD display devices and can be controlled but the Lenovo the player while adding my album has been pushed Depends on when to play and stops music is still open and to play through the background process If the player then with the open player without any problems.
At Samsung, it is still being tested.
