Need Recommendation..

1. Brand: Any
2. Budget: Below 2k
3. Specs: 2GB Ram (3GB better) / Screen size (more than 5" better)
4. What you need in the phone (Quality/Durable/Most important no LAG) best camera/battery

im currently using htc m8 but it lags so bad now
i think probably will be ok if i reset it but my coc will be deleted so wanna find new one before reset
probably gonna sell m8 after

so many phones now hard for me to choose
im looking for note 4 2nd hnd but my experience with note 2 is quite bad..so not sure bout samsung
i love htc but their new phones seems meh..n camera is not the best

im thinking also to try sony phone but sony screen looks bad
