Android - Last position in seekbar is difficult to reach -
i have seekbar 4 positions, first 3 works well, reach last position have move finger outside seekbar. i'll try put example:
1 2 3 4 ↓ ↓ ↓ ↓ -------------------- | seekbar | -------------------- ↑ ↑ ↑ ↑ 1 2 3 4 the arrows above steps set, arrows below zone have put finger set arrow in position, first 3 positions works zones near them, last must @ position or after (i can't touch after that, because there no screen left).
