Osmand-friendly device

I am seeking the device with support of Osmand Android App. Now I am trying to use it with Galaxy Relay phone, but this device cannot catch GPS signal thoroughly and generally is not functioning well.
Is there any device approved by Osmand and which has proven its reliability/compatibility with it?

What about Motorola Moto G … or Moto E ?

Both are quite affordable!

Definitely get an unlocked Moto G. It doesn’t have 4GLTE but it’s pretty good phone and affordable. Make sure it’s the 2nd gen and not the obsolete 1st gen. There’s no difference in price on those two so it’s better to get the newest.
