After being with windows mobile in its various guises since WM6.5... HTC Touch HD, Samsung Omnia 7, Lumina 800, Lumia 1020 and my current Lumina 950, I finally had enough yesterday and ordered a Galaxy S7.
I've not been happy with my 950 since having it and successive updates only seem to have made it worse. It refuses to receive push notifications on time, battery is terrible, supported apps have been decreasing in number, Bluetooth is patchy along with numerous other quibbles. Hard resets made no difference.
Final nail in the coffin for me was the creators update. Since that I've been having random freezing, crashes, even worse battery life, weird screen artefacts, emails are hit and miss now, data connection randomly stops working, WiFi is temperamental and push notifications are even worse than before.
I go with a heavy heart. I really love this platform and was heavily invested in the MS ecosystem. Phone, tablet, desktop, Xbox, Groove music, Xbox live etc... but Microsoft complete apathy towards mobile has done for me.
I have mixed feelings. Part of me is excited to try something new, popular and well supported etc. But then I am genuinely sad as I feel I've been driven away from using this by MS themselves.
