check out this tempered glass that has matching coloured sides to fully cover note 4. Anyone tried it before?

looks good in pics. Seller said it has curved edges but not very confident with the brand lol

It is a known issue for many devices. Sometimes charging interferes with screen sensitivity.

My note 4 review after 4 months. Jumped from Xperia Z.
- Before Root got about 3.5hours SOT. After root + Greenify + change browser to CM browser = 6 - 7 hours SOT.
- TBH, this is my first Samsung and I find Touchwiz to be feature packed and snappy. The exynos chip and 3gb ram can be thanked for that. Gain root and remove the bloatware.
- Note4 confirm has signal issues. A user claiming to be a network technician said N4 was underwhelming in their tests. However, just because you don't have a full bar, doesn't necessarily mean the data speed is bad. Just means signal may change from H+ to 3G easier. I found by selecting only WDCMA/GSM instead with LTE, I have a slightly more stable signal. Overall disappointed this area of phone.
- I use celcom line and have not encountered drop calls like some digi customers.
- Phone heat during heavy usage is fine by my standards, try holding an Xperia Z while playing a graphic intensive game,  now that is HOT.
- if u really want to save batt, stop using Chrome browser.  Dolphin and CM browser really makes a difference. Just needs getting used to. 
- If you have poor signal issues, advisable not to use a bumper with metal or aluminium. It is known to affect signal reception. First made known in xda forums with the verus iron shield.
- Camera is a freaking beast. My most loved feature in this phone. If free, will post some photos. In fact others should to.
- Love the Spen. Use it to make notes and have a lot of fun making doodles on photos of friends.
- Bluetooth works well, listening beat music via wireless earphones while shopping in Tesco is priceless.
- Screen quality is really amazing. If you upgrading from 2/3 ++ year old phone, be prepared to pamper your eyes.
- For me sound from rear speaker is pretty ok and loud but only when it's not laid on its back or covered up.
- For a big phone, the vibration when phone rings or from notifications is not strong enough.
- I find the autobrightness sensor to be not fast enough to detect changes to ambient lighting but it definately has a great wide range of brightness to select.
- Fast charging is OMG! Where have you been all this while?
- If you are facing buggy IR blaster, uninstall all updates to get it to work again.
- Really cool mobile multimedia consumption device - games, movies, shows, music.
That's all I can think off. If you can afford this phone, and live in an area with good network reception, then go ahead and buy this phone.

If you just flashed lollipop, give it a few days to regain the battery life. Can't say if custom rom will have battery issues or not but most custom rom tends to be more optimized than stock, but if a bug(eg: battery issue) exist on stock rom, it will most likely be carried over to the custom roms that based on it.
Nova Launcher Prime, I have been using it on all my android devices.
