had to downgrade to 2.7 because of dc issues every say 20 min or so, also when making calls, earpiece speaker not working just external speaker, so no privacy unless you use headset. hey thats no good, and there is no option to switch between speakers, so hey microsoft, fix please, or you will have lots of paid customers like myself, changing apps, like viber is great, and stable. also with new 2.8 when making a call, you hear two types of ring tones when making call, update please and fix, or again you will start losing customers
