A:AnswerYes it will work with the S9 and beyond. It works great for my Note 9 and for my wife's Iphone XR. Only reason it may not work for a phone that is wireless charging capable is if that phone is in a case that doesnt allow wireless charging through it because of material or it is too think. Wife and I both have Otterbox Cases on our phones and it does work with them.
A:AnswerI have a Samsung Galaxy S9+ and it will sometimes charge. But doesn't increase the battery just keeps it at whatever percentage you had before putting it in the holder.
A:AnswerI have a Note 9 but it is slightly larger than the Pixel 4. My phone fits fine in the holder with room to spare. I have an OtterBox case and that does not hurt the charging feature. My phone always connects to the charger.
A:AnswerNo not at all. so far for what I have notice it leaves a ring around the dash board which I WBA’s able to clean off easily with basic car cleaning products.
A:AnswerYes it will! I have an Xs max, and it works perfectly with it. I even have my phone in a otter box symmetry case, and it still charges the phone!
A:AnswerThis will be fairly easy to take off once you are done. If any residue is seen, it usually is from dust buildup. Use windex or some type of cleaner to easily wipe off the residue. DONE!
